Now is a good time to plant baby lettuce, spinach and micro-greens for early Fall harvest. You do not need a deep container to grow salad greens and you can grow the greens from seed. Covering the potted seeds with loose plastic wrap holds the moisture and heat and encourages sprouting.
Growing Container Salad Greens: “You will be able to harvest your first crop in just a few short weeks, using the small tender leaves that are often not available to buy. These micro-greens are the mix of choice for gourmet salads. Leafy greens also make a flavorful addition to sandwiches or wraps.”
Radishes also mature quickly. Use radish greens instead of basil in your pesto recipe.
As a container gardener you can quickly move your salad bowl inside if we get a sudden Colorado frost. In a sunny window you can keep growing salad all winter.
If you need an incentive, a CSU Extension publication lists the nutrients in different salad greens and has notes about taste. It has great photos — I can now identify Mizuna. Enjoy!
