Gardening isn't just good for the planet, it's good for you. Even if you're just getting started, gardening can increase your activity levels and lower your stress. According to the Mayo Clinic, the activity can also get you outside more, improve your diet and help build your social connections. But not every flower or vegetable is suitable for spring gardening. To have the best success and reduce frustration, you need to know when it's the best time to plant. Here are suggestions for what to grow in May.
Plants don't have an iPhone or a calendar to tell them what day it is. Instead, they rely on environmental clues. Since the Earth is on a tilt, the length of day and intensity of the sunlight as well as the temperature are all in a constant state of change. Plants register these factors and use their built-in circadian clock to evaluate them and determine which season it is. This is how a plant knows if it is time to grow, blossom or go dormant.
If you've ever gone out to dinner on a Friday or Saturday night at around 6 p.m., the experience can be more frustrating than enjoyable. This is because it's a popular time to go out, so everyone is trying to get their fill from a limited amount of resources. If you dine at 4 p.m., you can get what you need without trouble.
Nature is the same way. If every plant bloomed at the same time, there wouldn't be enough resources to sustain all life. Consequently, the amount of time it takes a plant to go from seed to sprout to full maturity is different for each plant. The prime growing season differs from plant to plant as well. Some flowers will thrive when you plant them in May, while others might not do as well. To have the best flower or vegetable garden, you need to know which seeds are best sown now.
Just a few hours of temperatures that are at or below freezing can be enough to damage or even kill your tender spring seedlings. It's important to only plant after the risk of overnight frost has passed. However, most plants won't germinate until the soil is around 60 degrees. Even when there's no longer a risk of frost, if your soil isn't warm enough, your seeds won't turn into plants. Additionally, planting (or transplanting) too early in the gardening season can cause wilting and stunted growth as well as increased susceptibility to disease.
In May, the temperatures across most of the United States are warm enough and stable enough to begin planting outdoors. It's early enough to give you the maximum amount of safe growing time for plants that thrive in warm weather, and it's a good time for plants that require a longer time until harvest.
If you want to sow vegetable seeds or flower seeds, May is a good time for green beans, corn, gladiolas, dill, cilantro, lilies, squash, parsley, sunflowers and more. For transplants, May works for tomatoes, mums, peppers, thyme, mint, eggplant, cucumber, blueberries, zucchini and others.
