On this page, we will explore a wide range of edible and landscape plants that you can plant in May in Zone to help you maximize your garden’s potential.

Warm Weather Vegetables To Plant

Tomatoes

Tomatoes are one of the most popular garden vegetables and are perfect for planting in May, as they thrive in environments where temperatures are consistently between 70°F and 85°F. When planting, ensure to choose a sunny location, as tomatoes require at least six to eight hours of sunlight each day. Consider starting with disease-resistant varieties like ‘Early Girl’ for a quick yield. Planting tomatoes in well-drained, nutrient-rich soil is crucial; adding compost can help improve soil structure and nutrient content. Stake or cage them early to avoid stressing the plant later during its growth.

Peppers

Capable of producing sweet or spicy fruits, peppers should be planted in May after the soil temperature reaches at least 70°F. They prefer similar conditions to tomatoes, thriving in full sun, with ample watering to support fruit development. To encourage growth, consider using a balanced fertilizer before planting and then applying a slow-release fertilizer as the plants flower. Be mindful to space plants 18 inches apart to allow for airflow, which helps reduce the risk of blossom end rot and fungal diseases.

Eggplant

Eggplants flourish in heat, making May the ideal time for planting. These vegetables love full sun and can be grown in containers or traditional garden beds. For best results, amend the soil with organic matter to retain moisture and provide nutrients. Eggplants can suffer from pests like aphids and flea beetles, so consider using row covers early in the season to protect young plants, then manage pests with organic insecticidal soap if necessary.

Cucumbers

Cucumbers are quick-growing vegetables that do best in well-drained soil and sunny conditions. Planting them in mounds allows for better drainage, which reduces the risk of rot. Setting up trellises can save space and promote air circulation around the plants. Regular watering is essential, especially during dry spells, to prevent bitter-tasting cucumbers. You can sow seeds directly into the soil or start seedlings indoors for a jumpstart.

Squash

Zucchini and summer squash can be planted directly in the garden soil in May, utilizing the heat for rapid growth. Select a location with full sun and ensure the soil is rich in organic matter for optimal yields. To prevent common pests like squash bugs and vine borers, consider interplanting with herbs like basil or marigolds, which may deter these pests naturally. Hand-pollination can also boost fruit development during blooming.

Beans

Beans are a warm-weather crop that can be directly sown in May when soil temperatures are warm enough. They enrich the soil naturally through nitrogen fixation, which benefits subsequent plants. Plant bush varieties for easier harvesting or pole varieties for vertical growth; both require adequate spacing for moisture and nutrient absorption. Regular but moderate watering is crucial during flowering and pod development to ensure a good harvest.

Corn

Corn is a classic summer vegetable that loves the heat, making May its ideal planting month. When planting, sow seeds in blocks rather than single rows; this ensures better pollination, which directly affects the yield. Corn thrives in rich, well-drained soil and benefits significantly from regular moisture during tasseling and cob formation. Using mulch can help retain soil moisture and suppress weeds.

Okra

Given its love for warmth, okra can be a great addition to a May garden. Start seeds in a sunny spot with well-draining soil and watch for growth as temperatures soar. Its fleshy pods can be harvested early for tender eating, but allow them to grow larger for drying and cooking. Watering deeply but infrequently encourages strong roots, so be mindful of soil moisture levels!

Melons

Melons thrive in the warmth of late spring and into summer. They prefer sandy or loamy soils and ample sunlight. Plant seeds directly in the garden with plenty of space for sprawling vines—ensure sun exposure for optimal sweetness. Use mulch to regulate soil temperature, keep moisture, and suppress weeds. When fruits begin to develop, try to keep soil consistently moist but not waterlogged.

Sweet Potatoes

Planting sweet potatoes in May allows the tubers to develop throughout the warm summer months. They require well-draining soil and should be planted in mounds to encourage drainage. Providing adequate spacing is crucial, while the plants also accept regular fertilization, especially if the foliage turns yellow. Keep the soil moist, as this helps reduce stress during the hot summer.
