No More Buds? Turn to Earbuds.

By this time in the year, I’m at the point of good riddance! with the weeds and careful tending (shout out to this cold spell for sealing the deal). Pretty much everything is done and put to bed. I then spend the next two weeks really dialing into my houseplant game before I get bored and start Spring dreaming. My Fall break from the garden is short-lived so I start listening to old episodes of now-defunct podcast series and dream with new ones.  Here are a few of my favs:

Gardenerd Tip of The Week

Gardenerd.com is the ultimate resource for garden nerds. We provide organic gardening information whenever you need it, helping you turn land, public space, and containers into a more satisfying and productive garden that is capable of producing better-tasting and healthier food.

https://gardenerd.com/

My thoughts: The host lives in LA, so this one is great for winter listening as we get chillier, I love hearing about the warmth of Southern California and what’s coming into season. Interviews with other experts and educators in the horticulture field discussing plants, but also cultivating grains, discussing bees, and seeds. Each episode ends with the guest’s own tips, many of which are news to me and have been incorporated into my own practices. 

On the Ledge

I’m Jane Perrone, and I’ve been growing houseplants since I was a child, caring for cacti in my bedroom and growing a grapefruit from seed; filling a fishtank full of fittonias and bringing African violets back from the dead.

https://www.janeperrone.com/on-the-ledge

Houseplants, if new to the podcast start here for an overview, and guidance.

Jane is a freelance journalist and presenter on gardening topics. Her podcast has a ton of tips for beginners, and more advanced info for longtime houseplant lovers, as well as interviews with other plant experts. The website is also useful to explore the content of an episode if you aren’t able to listen. I could spend an entire morning traveling in and out of the archives. 

My thoughts: As the growing season comes to a close, my indoors watering schedule starts wobbling between what the plants need and my summer habits of watering too many times per week–welcome back,  fungus gnats! Here’s an entire episode on them

Plant Daddy Podcast

We aim to create a listener community around houseplants, to learn things, teach things, share conversations with experts, professionals in the horticulture industry, and amateur hobbyists like ourselves. We also want to bring the conversation beyond plants, since anybody with leaf babies has a multitude of intersectional identities. We, ourselves, are a couple gay guys living in Seattle, Washington, with a passion for gardening and houseplants. A lot of our friends are the same, though each of us has a different connection, interest, and set of skills in this hobby, demonstrating a small amount of the diversity we want to highlight among plant enthusiasts.

https://plantdaddypodcast.com/

My thoughts: Plants are visual, podcasts are auditory- episodic overviews with links to viewable content available on their website. Are you also seeing Staghorn Ferns everywhere? They have an entire episode (photos included!) on the fern and how to properly mount it for that vegan taxiderm look. Matthew and Stephen are self-identified hobbyists with a passion for plants all the way down to the Latin–it’s impressive.

Epic Gardening

The Epic Gardening podcast…where your gardening questions are answered daily! The goal of this podcast is to give you a little boost of gardening wisdom in under 10 minutes a day. I cover a wide range of topics, from pest prevention, to hydroponics, to plant care guides…as long as it has something to do with gardening, I’ll talk about it on the show!

https://www.epicgardening.com/

My thoughts: The Netflix-episode-when-you-just-don’t-feel-like-a-movie kind of podcast. Addresses the best varietals, composting, soil pH, and troubleshooting some common issues in the garden. With daily episodes archived back to December 2018, there is a quickly digested thought for some of your own curiosities. The website is also a wealth of knowledge. 

Eatweeds Podcast: For People Who Love Plants

Eatweeds: An audio journey through the wonderful wild world of plants. Episodes cover modern and ancient ways wild plants have been used in human culture as food, medicine and utilitarian uses.

http://eatweeds.libsyn.com/

My thoughts: most recent episode (and appropriately timed!)  On edible acorns. My fav topics include foraging and wild yeast fermentation; and when I really start missing the Pacific Northwest, The Wild and Wonderful World of Fungi sends me back to a misty forest wander politely decorated by les champignons. Posting of this pod is sporadic–only 25 episodes since 2014.

You Bet Your Garden

(no longer on air, but archives available)

 

You Bet Your Garden® was a weekly radio show and podcast produced at WHYY through September, 2018. The show’s archive is available online. It was a weekly syndicated radio show, with lots of call-ins. This weekly call-in program offers ‘fiercely organic’ advice to gardeners far and wide.

https://www.wlvt.org/television/you-bet-your-garden/

My thoughts: Host, Mike McGrath, spends much of the show taking calls and troubleshooting, reminiscent of another public radio behemoth with Click and Clack, the Tappet brothers. McGrath incorporates a lifetime of organic gardening tips with humor. McGrath features one tip to find a local “rent a goat place” (no joke) to get goats to eat the most troublesome weeds to a concerned caller considering setting much of her yard on fire.

Cultivating Place: Conversations on Natural History and the Human Impulse to Garden

Jennifer Jewell, the founder of Jewellgarden and Cultivating Place, achieves this mission through her writing, photographs, exhibits about and advocacy for gardens & natural history and through her weekly public radio program and podcast Cultivating Place: Conversations on Natural History and the Human Impulse to Garden, on gardens as integral to our natural and cultural literacy.

https://www.cultivatingplace.com/

My thoughts: sort of like On Being, but for gardening.

A fav episode:

If you aren’t so sure about this podcast thing, and just want a place to start, start here.

Do you really need a brain to sense the world around you? To remember? Or even learn? Well, it depends on who you ask. Jad and Robert, they are split on this one. Today, Robert drags Jad along on a parade for the surprising feats of brainless plants. Along with a home-inspection duo, a science writer, and some enterprising scientists at Princeton University, we dig into the work of evolutionary ecologist Monica Gagliano, who turns our brain-centered worldview on its head through a series of clever experiments that show plants doing things we never would’ve imagined. Can Robert get Jad to join the march?

tree walk.

Last Monday, my dear friend and Community Forester, Chuck Sugent, and I took a neighborhood stroll to identify trees because I find myself recommending (or “oh, that’s an oh-no-no’ tree!”) at the farmer’s market; but when it comes down to it, I can hardly identify any trees at all and rely on the Front Range Tree Recommendation List. or the Denver approved tree list. My learning style is not entirely visual but seeing and discussing something certainly increases the likelihood of future accurate recitation. After a minor location miscommunication (“Heading your way!” “Good thing you sent that. I thought I was heading your way. Oy!”), we set off through a tree-lined neighborhood between downtown and City Park.

Chuck is the kinda guy who’s gonna be the good guy: he’s got the information, and he wants to share it (perhaps with an old-timey gangster of New York wiseguy affectation). So he took no pause when I suggested the idea of a tree walk. We’ve talked about the CMG program and community forestry in terms of our own participation for community stewardship, and have oft discussed a crossover—and thus, we went! We set off to name the trees and, in addition, ended up pretend-pruning, dreaming, and trouble-shooting all the ailments. Everything I espouse, I learned from Chuck (it was a very informative afternoon). Here’s an absurdly simplistic overview of the main players:

Crabapples

Gorgeous and quite popular. Responsible for the pinkening of the city each spring. Many varieties of different sizes and fruits. Also, edible. I grew up with a crabapple tree at my grandmother’s house which was the source of many summers dares to the youngest of us to “just try it! You’ll love it!” followed by giggle fits at the sight of desperate acceptance puckering away at the tiny bite. So—raw is a no, but cooked with sugar and acid makes for delicious desserts; or my family fav: Crabapple whiskey. Fill a jar with crabapples, a cinnamon stick, ginger, cloves and top with whiskey. Tuck it away until Christmas, strain and serve.

Silver Maple

Thirsty mother lovers. They grow quickly and provide lots of shade. We have a ton of them in our metro canopy, but they are currently on a moratorium from planting in city right-of-way areas.

Honeylocust/Black Locust

Black Locust has a darker trunk than the Honeylocust. Tiny leaves, gorgeous lemon color through the fall. However, tiny leaves make a mega mess–however, however, the leaves decompose quickly and return the nutrients to the soil. Also, a popular choice in this area, and continues to be on recommended tree lists for a new planting (NOTE: many varieties are on the recommended list, but the Sunburst Honeylocust is also on the moratorium list for street planting in Denver)

Sugar Maple

Classic Canadian flag. Gorgeous flaming fall coloring. The moisture level is moderate for this group, and they do not tolerate salty soil very well but are fairly drought tolerant. 

Hackberry

This one makes Chuck’s shortlist of recommended trees for the metro area. The Hackberry has no known local pest, is native to Colorado, and drought tolerant. The Hackberry can get up to 50 feet tall, so consider this one for a street-side as a shade option. Lovely red berries darken to maroon in the Fall and provide home and a food source to the critters. Chuck calls this one a Hammer Tree; an all-around good selection.

Linden

When we happened upon our first Linden of the walk, Chuck took a step aside and said, “There are two kinds of Linden trees, and here’s how I remember them: LLL.” At this point, he raises his voice to denote the first type “LARGE LEAF LINDEN” followed by a substantially lower volume for the “littleleaf Linden.” He proceeded to crack himself up, and we carried on. There are many cultivars of Linden recommended in this area. Lindens are an attractive pyramidal shape, sensitive to salty soils, and their flowers attract bees and birds. Beware of the area you are considering, Lindens do not love high heat areas and should be planted away from any hardscaping. 

Oak

Ever sturdy and reliable. The oak leaves have a bit of a leathery texture to reduce evapotranspiration, making them more drought-tolerant, and an excellent tree choice for this area. Their leaves differ in pattern depending on the cultivar but typically have the characteristic lobes and sinuses. The Bur Oak (recommended for the Metro area), is roughly obovate with many lobes and is pale and fuzzy underneath.

Ash

If you’re reading this… need I say more? See Plum for contingency planning. We have a million (estimated 1.45 million in the Denver Metro area) Ash trees. Aside from the EAB creeping into town, the Ash tree has a tendency to appear real leggy under the canopy when not properly pruned. We saw many examples of Ash trees with a lot of deadwood inside the canopy; this can be problematic when the wind picks up. They served a great function for our canopy by growing quickly and providing robust shade; but unfortunately, we’ve got to continue considering the impending Armageddon. What build projects shall we consider for a future influx of Ashwood? Denver also has a moratorium on planting Ash trees in public right-of-ways. 

Plum

The purple leaf plum is my fan fav, and will likely be planted in my own front yard next Spring since my future self called and said: “This giant elm thing in your front yard was planted improperly, is massive, and when it goes, your front yard is gonna be U.G.L.Y.” Contingency planning in full swing. I encourage y’all to take a walkabout your own homes and chat with future self, especially regarding anything that is shade bearing. Something I picked up from my buddy whilst traipsing on the tree walk: purple leaf plums require regular pruning for flowering (Is anyone else as smitten by the plurality of prunes in this context?)  Remove the deadwood and prune 1/3 the length of new growth. We found a perfect example and made pernicious prunes with finger scissors.

Colorado Blue Spruce

Beautiful. Also better at a higher elevation. We did see a few stunners, though, and learned a neat trick for tree ID: the leaf of a fir tree will be flat and flexible. Spruce, on the other hand, will be square and sharp (see what he did there?). Grab a leaf, roll it between your fingers, and name it quickly with this handy guide.

Aspen

May make it to a mature size but inevitably will crash and burn. I’ve been touting this gospel for a while now, and take every opportunity to point out a struggler to my wife. which has become problematic, because now she counters by showing me all the healthy Aspen in the Metro area. The truth of the matter is an aspen tree (or maybe even a small clump of them) has the ability to thrive with the proper tender loving care… for a while. Above and beyond the statistically insignificant number of Aspen in the front range who appear to be doing well, they aren’t built for this elevation, and forcing them to do so causes undue stress, and makes them more vulnerable, hastening their predisposition to die anyway. Don’t do it. Go to the mountains more often and enjoy them in their own territory.


Beyond my self-imposed (and singularly played) trivia that entailed me interrupting, pointing, and shouting guesses; we also discussed the conversational piece of tree maintenance. Chuck indicated he has many chats with his neighbors about their trees and takes these moments to build his community and integrate his passion with friendly educational moments. We discussed the evidentiary tribulations of a tree in demise, that twists it’s trunk and bears the stripes of turmoil. We debated the suckers: their yappy attempts to address internal stress, and what to do with them (should we leave them and let it try to capture the energy it is craving? OR whack them back always? And when?) We talked about injury to a tree, and how the tree may cover and scab the wound, but the wound remains and the tree is still vulnerable. Chuck showed me a hackberry tree covered in galls. We both got lost in our attempts to recall the origins but settled on something about defense mechanisms and how they rarely hurt the tree.

As we were nearing our last corner on the way home, Chuck remembered a tree we hadn’t encountered that he loves. I’ve developed a habit this summer that whenever I see this tree, I shout it’s name, probably because it’s so fun to say, but shouting also seems appropriate just to communicate the whimsy of the CATALPA! Just try and say it without a bit of a shout. The Catalpa is also a recommended and robust tree for our area. It’s got those built-in wands and/or swords for play, and bright green wide leaves provide a huge amount of shade. . They are another tough tree, worthy of your scape.

Other items on Chuck’s “Oh no-no” list? Planting a tree too deep? Oh, no-no. Scoffing at the bare root and opting for a burlapped and caged tree? Oh, no-no. Planting anything from the Birch fam in Denver? Oh no-no.  Hiring an arborist annually to tame your trees? Oh, no-no. With a little reading, Youtube-ing, or friendly forester finding, folks can save bunches of bucks by learning how to make the minor pruning adjustments to your tree every year to avoid the future big bills from an arborist. Trees can easily be grown and cared for by their owners working from reliable and factual info. Of course, always consult a pro when your tree questions start toeing the line safe vs. unsafe. 

https://extension.colostate.edu/topic-areas/yard-garden/#trees

As DMG’s we get loads of questions about trees at the farmer’s markets. We try our best to offer small sagelings of fact-checked info, but what I’ve found to be more helpful is keeping the company of a forester. Trees are just as essential to the garden crew as our lawns, beds, and weeds. I encourage everyone to branch out (a thousand apologies for that one) and get connected–or get involved and become a Community Forester, yourself!


PS. Did you know if you live in Denver you can get nearly *free* trees?

Heirloom and Modern Tomatoes at CSU’s Master Gardener Plant Sale

The 14th annual CSU Master Gardener plant sale fundraiser will take place at Denver’s Harvard Gulch Park, 888 E Iliff Avenue (at Emerson) on Saturday, May 18 from 8 am to 3 pm and Sunday May 19 from 10am to 3pm or till sold out.

In preparation for the sale, Denver Master Gardeners have been busy nurturing over 7200 fruit and vegetable plants from seed in the City of Denver’s City Park Greenhouse. When the plants make their debut you’ll find a dizzying selection of strong, healthy specimens for your summer garden. Herbs, annuals and perennials round out the offerings.

The tomato plants are definitely one of the stars of the show – forty seven varieties in all – including heirloom and modern (hybrid) cultivars.

What differentiates a heirloom from a modern tomato?

Horticulturists define heirloom seeds as those that are “open pollinated” by  insects, birds, wind or other natural means and retain the same traits from generation to generation. Seedlings will produce the same size and color fruit on a plant with the same growth habit and the same flavor from one generation to the next.

Depending on the variety, heirloom tomatoes can be red, purple, green, yellow, speckled or bi-colored. The fruit can have smooth skin but many varieties have a beautiful ribbed surface. Popular indeterminate (produce fruit throughout the season after maturity) heirlooms available at the sale include:

 

‘Brandywine Red’ – a large, flavorful red-pink beefsteak fruit which matures in 90 days.

‘Purple Cherokee’ – pink-purple fruit with a rich, sweet flavor. Excellent in salads and on sandwiches. Matures in 80-90 days.

‘San Marzano’ – Favored by Italian cooks for a meaty, complex, sweet flavor which is especially delicious on pizza and in sauces. Matures in 85-90 days.

‘Aunt Ruby’s German Green’ – Large (up to 1 lb!) green fruit with a strong, sweet fruity flavor. A frequent taste test winner which slices especially well. Matures in 85 days.

Many experts define heirloom seeds as those introduced prior to 1950. By contrast, modern (hybrid) varieties were introduced to the market after World War II for the purpose of improving disease resistance and increasing shelf life and yields. The modern varieties became popular because the home gardener could avoid battling tomato diseases and commercial growers could count on reliable, cost effective crops.

If you are thinking that modern tomatoes lack classic, true tomato taste, you are not alone. Some hybrids sacrifice flavor for other traits. However, in fairness, taste is highly subjective!  

Modern varieties are popular taste-pleasers and are definitely worth adding to your garden. We’ve grown ten hybrid cultivars including two crowd pleasing indeterminate cherry varieties.

‘Cherry Sun Gold’ – Prolific golden-orange cherry-sized fruit with high sugar content. A frequent taste test winner which can be grown in a large pot. Matures in 70 days. Kids eat ‘em like candy!

‘Chocolate Cherry’ – Clusters of 1” port wine fruit with a rich, tangy flavor. A productive plant which matures in 70 days.

As Plant Sale Chair Maureen Horton explained here, two heirloom marriage tomatoes ‘Cherokee Carbon’ and ‘Genuwine’ are new this year. Heirloom marriage tomatoes are hybrids that cross two heirloom varieties to produce a tomato with the best qualities of each heirloom.

Truly the “best” tomatoes are the ones you enjoy the most and thrive in your garden. It’s also fun to introduce a new variety to your garden and palette. If you join us for the sale, master gardeners will help you make your selection and share tips for success.

Colorado Blueberries: A Success Story

Blueberries grown in peat moss bales

Make no mistake about it, blueberry plants want what Colorado’s soils can’t deliver – high acidity. Attempts to grow them in our alkaline soil will frustrate the most accomplished gardener. However, research at Colorado State University found the plants can be grown successfully in this region when planted directly into a bale of peat moss, which has been tucked into the garden bed. The process is described in detail here.

Five years ago, armed with bales of peat, solid research and determination, Denver Master Gardener Jill Fielder decided to add blueberries to her raised beds. Given the proper environment, regular care and careful plant selection, she’s been enjoying berries every summer since.

According to Jill, “Blueberries are both insect and wind pollinated and the bees love ours. Most experts believe that blueberries set great yields when there’s cross pollination with another variety that flowers at the same time, so we have a couple different cultivars.” Northcountry Blue (small, flavorful berries, upright habit), Bluegold, (productive with a somewhat sprawling habit) and Bluecrop (large berries, the newest addition) are 3.5′ to 4.5′ feet tall and doing well. Northblue didn’t produce well and was replaced.

Spring buds

Plants were purchased on-line from reputable growers and were planted in the spring. The plants are feed monthly during the growing season with a water soluble fertilizer for acid-loving plants. A drip irrigation system provides moisture.

Jill’s raised beds are in a protected area of her yard, bordered by a fence and garage so she has not covered or wrapped the plants in the winter. However, winter protection is recommended in less protected areas. Late in the winter, plants are trimmed to remove dead or damaged wood and maintain shape.

If you’re looking for a new gardening challenge and can commit to the specific needs of these plants, why not give them a try?

Espalier Tree: An Experiment

Espaliers are a beautiful addition for: a kitchen garden wall, the side of a house, plopping under window, a privacy screen or employed as yard zone divider. Espaliers take up very little space and are easily accessible for people with limited mobility, and also a fun height for children to harvest. Moreover, espalier fruit trees have surprisingly bountiful fruit production. And interestingly espaliers often live longer than more naturally grown trees/vines, including some very old specimens. These plants have the advantages of sunlight that reaches all the branches, less breakage, and importantly if planted against a wall they have the added protection against a late frost, and so potentially retain more blossoms.

When we first moved into our house there was a wall in a small garden that I felt needed a pear espalier. I didn’t feel brave enough (or patient probably) to start a bare-root dwarf fruit tree and establish the training from scratch. So a couple of years ticked by as I waited to win the lottery for a nursery grown one (a four tier espalier can cost over a thousand dollars). The more affordable two tier plants, that are more commonly sold, are perfect for planting under a window, but not for a taller height. To add to this, most of the nursery grafted espaliers have a different variety of fruit on each branch, which although theoretically sounds exciting can actually present aesthetic and practical issues, and not surprisingly the rootstock can dominate in time too.

My experiment was – could I take a mature sapling and train it into an espalier. I am writing this blog as I did not find the information I needed on the internet, and so I plunged ahead into the unknown and broke pretty much every gardening rule. This is an experiment that may or may not succeed.  Any input will be gratefully received! The ideas below are not endorsed by any educated gardener.

I did follow one cardinal rule: “Right Plant- Right Place”. I had my heart set on a pear tree.  But at the nursery I chose the European Stanley Plum as the “right plant”.  It is a hardy choice for Denver, and a larger tree (not a dwarf fruit- the regular espalier choice) should be alright for my wall? Moreover, this sapling had the right growth pattern, as it was fairly two dimensional and symmetrical.  This young tree also sported the required flexible branches for training. Then for the location: the eastern wall, which is bathed in sunlight but not unrelating heat was I felt this “right place”.  I followed correct planting rules! CMG How to Plant a Tree Continue reading

4 Ways to Share the Harvest

Share the HarvestOn August 8 I saw a picture on social media of three oversized zucchini squashes lined up against someone’s front door.

Apparently it was National Sneak Some Zucchini On Your Neighbor’s Porch Day and gardeners were making the most of it to get rid of their giant zucchinis.

I know summer squashes can be the punch line to gardening jokes, but I didn’t know there was a whole day devoted to surprising neighbors with jumbo fruits that might go to waste.

Good gardeners know that zucchinis are best when they’re small and tender. To avoid club-sized fruits, harvest early and often, when fruits are about 5-7 inches long. It pays to remember at the height of the season, fruits can be ready to pick within a week of flowering.

Instead of unloading zucchinis onto unsuspecting neighbors, why not donate the extra produce to people who will appreciate it? Here are four ways to share the harvest with a food pantry that will distribute it to our neighbors in need:

AmpleHarvest.org
Ample Harvest is a national charitable organization that connects gardeners with local food pantries by zip code. On the website homepage there’s a Find a Pantry button at the top of the page. When I keyed in my zip code, I found a dozen pantries within a 9-mile radius.

Colorado Hunger Free Hotline
In addition to being a food resource, the Colorado Hunger Free Hotline can help gardeners find a food pantry that accepts fresh produce. Call 855-855-4626 (Monday-Friday, 8:00 a.m. to 4:30 p.m.) and ask about food pantries located in your zip code. Then get in touch with the pantry for details about dropping off your fresh fruits and vegetables.

Fresh Food Connect
Fresh Food Connect is a local project of Groundwork Denver, Denver Food Rescue and Denver Urban Gardens. The program has three goals: reduce food waste, collect fresh produce and employ low-income youth. Fruits and vegetables are collected from your front porch and either donated or sold at a youth farm stand. If you live in zip code 80205, you can sign up and get a weekly email asking if you have any produce to donate. Someone on a bike with a trailer will ride by and pick it up.

Fresh Food Connect organizers say the program will expand to other neighborhoods, so even if you don’t live in the 80205 neighborhood, sign up so they’ll have an idea of where to expand the program in the future.

Project Angel Heart
Project Angel Heart takes fresh fruits, vegetables and herbs and turns them into healthful meals for their clients with life-threatening illnesses. Project Angel Heart has a list of accepted items, especially chard, tomatoes, zucchini! and yellow squash (see the full list and other details on the website).

Produce must be harvested and dropped off on the same day: Mondays, from 8:00 a.m. to 3:00 p.m., at the Denver office and kitchen (4950 Washington St.).

If you have a favorite drop-off spot, please add it to this list and help other gardeners find the best use for their extra produce. And let’s start celebrating zucchinis for their important role they play in our gardens — and kitchens.

How to Grow Blueberries in Colorado Gardens

BlueberriesColorado gardeners who fall in love with the idea of growing their own blueberries may be disappointed with the results. There just isn’t enough room on a planting tag for all the information they need.

Even if they carefully follow the basic planting instructions, blueberries need much more than “Full sun, acidic soil (incorporate peat moss or organic matter into soil), good drainage, fertilize in early spring, moderate watering.”

That’s because blueberry shrubs arrive in Colorado from growers in the northeast or the northwest where conditions are ideal for growing the plants. The climate on each of those coasts is significantly different from Colorado’s land-locked and semi-arid climate.

The two main challenges the blueberry planting tags don’t cover are the soil pH problems and the way winter dries out plants in our region.

Both of these problems can be solved, but it takes extra effort.

Thanks to CSU Extension blueberry experiments, gardeners have a proven blueprint for blueberry success.

The experiments, conducted by Joel Reich while he was a CSU Extension Horticulturist, are detailed in a one-hour webinar recorded in August 2012 called Blueberries for Colorado Gardens.

Anyone with online access can view the free program to learn all about the best blueberry varieties to plant, where to find them, how to plant and fertilize them, best practices for winter protection and how to keep birds and deer from getting to the juicy fruits before gardeners can enjoy them.

The blueberries growing in CSU’s trial gardens in Longmont show that if gardeners plant in sphagnum peat moss and provide special winter protection, they can enjoy fresh blueberries season after season.

Joel grew blueberries in the trial garden for more than 16 seasons in the same bales of peat moss. He devised a fertility maintenance program with a special combination of acidic fertilizers to use on a May, June, July schedule.

Planting

Best practices for planting blueberries mean planting directly inside the sphagnum peat moss bales. The bags are opened only part way to help retain moisture. Holes in the bottom of the bag provide drainage. Drip irrigation is important to make sure the soil stays consistently moist.

The bags are placed in trenches so they’re at grade level, but they could also be placed in a raised bed. Gardeners could grow plants in patio or balcony containers if they select the blueberries classified as “half-high.”  Plants growing in containers will need even more protection from wind in winter.

Protection

The key to providing winter protection is to prevent the damage caused by dry weather, low humidity and winds. It’s especially important to wrap or cover each plant so winter winds can’t suck the moisture out of the dormant buds.

The blueberry shrubs need to be wrapped in layers of burlap with the branches tied up and together. An alternative is to cover each plant with a trash barrel that’s weighted down.
