Gardening in USDA Zone 7b offers a unique advantage due to its temperate climate, characterized by four distinct seasons. Known for its mild winters and warm summers, Zone 7b allows for a diverse range of plants to flourish. May is particularly significant as it signifies the end of frost season, making it the perfect time to start planting various vegetables, flowers, fruits, and landscape plants.

Vegetables To Plant

May is the prime month for planting a wealth of vegetables, and Zone 7b’s climate allows for the growth of both cool-season and warm-season crops.

Tomatoes

Tomatoes are a staple vegetable and do exceptionally well in Zone 7b. It’s essential to plant them when the soil temperature reaches at least 60°F (about mid to late May). Choose disease-resistant varieties to combat common issues like blight and end rot. To encourage healthy growth, amend your soil with compost or well-rotted manure before planting, and consider adding mulch around the base to retain moisture and regulate soil temperature. Tomatoes prefer full sun and should be checked regularly for moisture, particularly in the hot summer months, as they are susceptible to blossom drop and sunscald if not adequately watered.

Peppers

Peppers thrive in warm soils and can be planted in late May after the last frost. In Zone 7b, varieties like bell peppers and jalapeños produce delicious fruit in ample sunshine. Start your seedlings indoors in early April to get a jump start, then transplant outside once the danger of frost has passed. They enjoy a sunny location and benefit from well-drained, fertile soil. Remember to keep them consistently watered; using a soaker hose can help to keep the foliage dry and minimize disease risk.

Cucumbers

Cucumbers can be direct-seeded into your garden in late May, where they’ll thrive in the sun. The warm climate of Zone 7b ensures rapid growth, and you can expect a harvest as soon as 50-70 days later. They prefer rich, sandy loam for good drainage, and regular watering is essential, especially during flowering and fruiting stages. Twining cucumbers up a trellis can save space and help decrease the likelihood of disease, as it keeps the fruit off the soil.

Beans

Beans are excellent companions to other crops in a vegetable garden. With the warm soil temperatures typical in May, both bush and pole beans can be directly seeded into well-tilled soil. Beans enrich the soil by fixing nitrogen, benefiting consecutive crops. Given their relatively fast growth, regular harvesting can encourage further production throughout the summer months. Remember that in Zone 7b, it’s crucial to plant them after the danger of frost passes to avoid damage from unexpected cold snaps.

Squash

Warm-weather squash, including zucchini, is best planted in May. Squash prefers rich, well-draining soil, and the warm temperatures in Zone 7b maximize their growth potential. They can be planted in mounds or hills to ensure good drainage, especially in wetter seasons. Regular watering and careful monitoring of pest populations—such as squash bugs and vine borers—will help maintain healthy plants.

Carrots

Carrots can be direct seeded into the garden in May; however, they prefer cooler weather and benefit from partial shade. The fertile, sandy soils of Zone 7b are ideal for root development. Carrots need consistent watering to avoid splitting and ensure sweet flavor. Thinning seedlings is crucial to allow adequate space, as overcrowding can lead to smaller, deformed roots.

Lettuce

While lettuce prefers cooler temperatures, heat-tolerant varieties can be successful when planted early in May. Zone 7b typically allows for succession planting, giving you continuous harvests. Provide partial shade during particularly hot spells to prevent bolting—a common issue with lettuce that can arise with heat stress. Regularly harvest outer leaves to encourage new growth.

Radishes

Radishes are among the fastest-growing crops, making them perfect for spring planting in Zone 7b. Sown directly into the ground, they thrive in loose, well-drained soil and can tolerate slightly cooler temperatures. Regular watering ensures crisp and flavorful roots, and staggered sowing every few weeks allows for continuous harvest.

Beets

May is a great time to plant beets, which will flourish in the warm, nutrient-rich soils of Zone 7b. Direct sow seeds into well-tilled soil, and keep them adequately watered to support steady growth. They also tolerate heat well—harvest both the roots and the greens for a versatile crop.

Pumpkins

Pumpkins should be planted in late May in Zone 7b, where they can take advantage of the warm soil and long growing season. They require ample space, so consider planting in mounds about 3 feet apart. Regular watering is essential during their growth stages, particularly before the heavy fruit sets in late summer, and incorporating straw mulch can help retain moisture and control weeds.

Flowers To Plant

May signifies a time to plant beautiful annuals and perennials that will add color and life to your garden.

Sunflowers

Sunflowers are not only cheerful but also highly adaptable to various soil conditions, making them an excellent choice for May planting. Their height can be a stunning focal point, especially when planted in large groups.
