Meet the Gardening Help Volunteers
The CSU Extension Master Gardeners usually pick up the gardening helpline at the Denver Botanic Gardens or answer questions when people walk-in the door. Even though buildings at DBG are closed for now, gardeners can still get their gardening questions answered by Gardening Help from Colorado Master Gardeners at Denver Botanic Gardens, only remotely.
The interest in gardening has soared ever since people have had to hunker down at home and find ways to keep busy. First-time gardeners will likely have questions on how to get started, what to plant now, what can grow in containers, and much more.
Even gardeners with some experience have questions, too. All gardening questions can be emailed to firstname.lastname@example.org and a CMG, working remotely, will reply by email.

Gardening Help is a project of the CSU Extension-Denver Master Gardeners at the DBG. Volunteers provide reliable and research-based information to thousands of home gardeners each year.
Volunteers commit to at least one year in the role, with a minimum of six shifts spread across the year. The commitment starts early in the year with an orientation and training from Nancy Downs, project coordinator.
Many volunteers are GH regulars and they return to the project every year. In addition to being an active CMG, they have to satisfy DBG volunteer requirements, too. That means they’re a member of the DBG and enrolled there as a volunteer.
Some of the key characteristics of GH volunteers are good research, plant identification and diagnostic skills. Because the project is located at DBG, volunteers need to keep on top of what’s blooming at the DBG by season, so they can answer common questions that might pop up.

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.
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.
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.
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.
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!
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.
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
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.
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
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?
Meet the Garden Squad is a new blog feature and a way to get better acquainted with some of our CSU Extension Master Gardener volunteers.
Meet Maureen Horton
The first CSU Master Gardener Plant Sale was a small community event on a Saturday in May. Only a few hands planted seeds for the 1400 plants available that year.
Over the last 14 years, the fundraiser for Denver Master Gardeners has grown to include 25 pairs of volunteer hands planting and tending more than 7,200 fruit and vegetable plants. The sale dates are May 18 and 19 this year.
While many things about the sale have changed, there’s something that’s remained the same: the work of Master Gardener Maureen Horton. She’s volunteered every year of the sale since the very beginning. She’s taken on the important task of coordinating all the planting in the City Park Greenhouse for the plant sale.
“I love filling the pots, planting the seeds, nurturing them and watching them grow,” she said. “It’s almost like a mother thing, nurturing them and then they go away, like your children.”
Maureen joined the Master Gardener program around 1999, but she’s been interested in nurturing plants since she was 5 or 6 years old. Her earliest gardening memories are of walking with her grandmother and uncle to tend the family garden plot in New Hampshire.
She recalls her grandma explaining the shoveling and watering to her, as well as harvesting lettuce and “lots and lots of potatoes.”
Now her Denver garden includes xeric plants, roses and her favorite ‘Purple Cherokee’ and ‘San Marzano’ tomatoes, among others.
Maureen’s approach to her own garden is all about nurturing, too. “Once I plant it, I nurture it to its maturity with care and the proper nutrients to grow the healthiest plant possible. It’s all about loving the soil and earth.”
She must really love the soil to commit to leading the greenhouse planting effort over six months each year, from November to sale day in May.
“We start in November and go through all the seeds we didn’t use the year before,” she explained. “We’re cost conscious and want to use all the seeds we can.”
Then the what-to-grow lists are compiled. One list includes the most popular plants from the previous sale. There’s another list of plants that are researched to find new, reliable varieties to add to the sale. Because of the heat and extreme weather from last summer, heat-tolerant tomatoes were researched for this year.
That list includes favorites like ‘Yellow Pear’, ‘Red Brandywine’, ‘Burbank Slicing’, ‘Costoluto Genovese’, ‘Great White’, ‘Green Giant’, ‘Marble Stripe’ and ‘Purple Calabash’.
In addition, two new heirloom marriage tomatoes are now growing for the sale: ‘Cherokee Carbon’ and ‘Genuwine’. Heirloom marriage tomatoes are hybrids that cross two heirloom varieties to produce a tomato with the best qualities of each heirloom, plus the disease resistance and improved yields of a hybrid tomato.
Chile pepper research also figured into the list for this year’s sale. Of 23 pepper varieties, 21 are from New Mexico State University’s Chile Pepper Institute in Las Cruces.
“We’ve really babied those peppers,” Maureen said. “We’re introducing 18 new varieties of chile peppers to the sale.”
One of the new varieties is ‘NuMex Trick or Treat’. This pepper looks like a habanero and has all of the flavor of one, but with none of the heat. Another unusual pepper is ‘NuMex Twilight’ chile, an edible ornamental with peppers that mature in color from purple to yellow, then orange to red.
Once the seed order is placed, Maureen figures how many total flats of seeds to plant and the number of flats for each variety. Much of that is determined by how many benches the greenhouse allocates to the Master Gardeners for the sale.
In exchange for the space in the greenhouse and the use of a couple of their machines, the greenhouse also benefits from the help of Master Gardener volunteers.
Once the call for volunteers goes out, “people come running. It may be 40 degrees outside, but it’s 72 degrees in the greenhouse,” Maureen said. “It’s wonderful in there.”
While the planting is serious business, there’s always time for a few laughs. “We love it. There’s a lot of camaraderie and there’s a passion for it. Everyone works hard during their three hours to meet the goal of planting 40 flats.”
Once planting is complete, there’s twice weekly maintenance needed right up to the time the plants leave the greenhouse headed for the sale.
Last year the plant sale raised $36,000 to support Master Gardener programs in the community. More than half of that total came from selling the plants grown in the greenhouse.
It’s easy to imagine a high level of stress goes with the responsibility of nurturing more than 7,000 plants for the biggest fundraising event of the year.
“From doing it all these years, there’s not much stress,” said Maureen. “You have to roll with the punches. The only stress is if a flat of seeds doesn’t come up.”

Do you have a stash of old seed packets tucked away with your gardening gear, thrown on a shelf in the garage or mingling with this-and-that in a drawer? I bet you do. Do they hold the promise of healthy plants or are they past their prime?
Seed packets have a sell-by date, but depending on the seed type and the storage, they can be viable far longer.
According to Colorado State University, flower and vegetable seeds can be stored at room temperature for a year without significant loss of germination. Given optimal dry and cool conditions, some seeds can be viable for up to ten years. Colorado’s semi-arid climate is advantageous for seed saving as moisture shortens seed’s shelf life. This CSU publication contains details on seed saving, the longevity of common plant seeds and germination rates.
If you want to know if your past season’s seeds are worth planting, you can easily find out by doing a germination test. Count out 10, 20, or 30 seeds and spread them on several layers of moistened paper towels. Carefully roll them in the paper so the seeds stay separated. Place the roll in a plastic bag and store in a warm spot without direct sunlight, such as the top of the refrigerator.
Check your seeds for signs of sprouting after 2-3 days and daily after that for about two weeks, keeping the towels moist. After that time, divide the number of sprouted seeds by the number you started with and you have the germination rate. You’ll likely find that the rate is reduced, but the seed is still useful if you plant more seed than you need, using the germination rate as a planting guide.
If few seeds sprout, they are too old and not worth saving. By doing the test, you’ll avoid being disappointed by poorly performing plants in the garden.
February is a great time to take stock of your seed stash and purchase what you need for the year. And if you have some still-good seed you don’t want, consider sharing them with a gardening friend or donating them to a school or community garden.

It’s only January, but seed catalogs are arriving in the mail and gardeners are dreaming of summer. One way to get a head start on your vegetable garden is to start your own seeds indoors. It is relatively inexpensive to create your own seed-starting set up. In the long run you will save money because seeds are cheaper to buy than plants. If you want to take it a step further, you can save even more money by saving seeds from your favorite plants to start next year.
One of the great benefits of starting your own plants indoors is the amazing variety of seeds available at garden centers and in catalogs. It’s great fun on a cold, snowy day to browse seed catalogs and find new and interesting varieties of your favorite vegetables to start for your garden.
Each type of seed has its own germination and growing requirements, but most seeds need to be started 6 -8 weeks before they will be planted in the ground. To get seeds to germinate, you will need adequate light and soil temperatures above 70 degrees. A warm sunny window may be adequate, but to ensure good germination and sturdy plants some extra help is often required. Cool soil temperatures and too little light will result in poor germination and spindly, weak plants.
To provide good light, use two four-foot florescent shop light fixtures suspended close

over the seedlings. The key to using florescent shop lights is to have one cool white and one warm white tube in each light fixture. The combination provides the proper light spectrum for growing plants. Keep the lights on for 16 hours a day using a simple light timer. To avoid leggy, weak plants, keep the lights very close to the tops of the plants. This can be accomplished by hanging the lights from chains that you can adjust up or down.
To get the seeds to germinate you will need a warm, moist (not wet) environment. To ensure the proper environment for germination, use peat pots placed in seed starting trays with clear plastic covers.
Seed tray and clear cover
The plastic covers keep the peat pots warm and moist until germination. Use a seed starting soil mix in the peat pots. Regular potting soil and soil from your garden are too heavy for starting seeds. Most seeds need soil temperatures of 70 degrees or above to germinate. To ensure adequate soil warmth, use heat mats under your seed starting trays.

Once the seeds have germinated and are growing, the heat mats and clear covers should be removed. The trays, covers, pots, starting mix and mats are all available at local garden centers.

Two four-foot shop light fixtures placed side by side fit perfectly over two standard 10.5” x 21” seed starting trays set end to end. Each tray holds 32 – 2.5” peat pots.
As the seedlings grow, raise the lights little by little to keep them just above the plants. Water just enough to keep the peat pots moist, but not soggy. The pots should not be sitting in standing water. Too much water will lead to poor germination and weak plants. You can also use a spray bottle to mist the plants to add moisture. Once the plants are growing and develop true leaves, a weak solution of a Miracle-Gro type fertilizer will promote strong plants. Put two or three seeds in each peat pot to make sure at least one plant germinates per pot. As the plants grow,

keep the strongest plant in each pot and thin by snipping the weaker seedlings near soil level. Always snip, don’t pull. Pulling out the weaker plants can disturb the roots of the remaining strong seedling.
About two weeks before you plan on putting the plants in the ground, start hardening off the plants by placing them outside for part of the day. Start off slowly! The leaves will be tender and susceptible to damage from too much sun or wind. Start with a few hours in dappled shade on a mild day. The daytime temperatures should be above 55 degrees. Day by day, the plants will become stronger and can be left out longer and in more direct sun. Do not leave them out overnight if the temperature will dip below 50. Peats pots are small and can dry out very fast. Make sure the plants have adequate water while hardening off. One way to avoid plants drying out while they are hardening off is to transplant the seedlings from peat pots to 4 ½ inch or one gallon pots with regular potting soil. The plants really take off with the extra room and the larger pots are not as prone to drying out.
After two weeks or so, your hardy plants are ready to go into your garden.
