On this page, we’ll give you an in-depth look at recommended vegetables, flowers, herbs, and landscape plants that thrive in June.

Vegetables To Plant

June is a vital month for planting various heat-loving vegetables. Here are ten exceptional choices to consider for your garden this summer.

Tomatoes

Tomatoes are a staple in summer gardens, celebrated for their rich flavor and versatility. Ideal temperatures for tomatoes range between 70°F and 85°F. In northern climates, such as USDA Zones 3 and 4, it’s best to start seeds indoors around 6-8 weeks before the last frost date and transplant seedlings into the garden by mid-June, once the soil has warmed sufficiently. In warmer zones (5-10), you can plant transplants or seeds directly in mid to late May, with June being perfect for planting any late varieties.

Tomatoes require full sun and well-draining soil rich in organic matter. They need consistent watering but should not be over-watered, as soggy soil can lead to root rot. A trellis, cage, or staking is recommended for vigorous varieties to ensure upward growth and allow for better air circulation.

Cucumbers

Cucumbers thrive in temperatures ranging from 70°F to 85°F. These warm-season crops should be directly seeded into the garden whenever soil temperatures reach a consistent level above 65°F, which typically occurs in early to mid-June in northern zones but as early as late May in areas like southern California (Zones 9-10). Cucumbers prefer full sun, well-drained soil, and ample watering; they are sensitive to drought, so regular moisture is crucial.

Rapid-growing, cucumbers can be cultivated in various forms—bush types are great for containers while vining varieties like ‘Marketmore 76’ can be planted in most garden beds. Mulching around the plants helps retain moisture and reduces weed competition, which is especially beneficial as temperatures rise.

Beans

Beans are among the fastest-maturing crops and thrive in warm temperatures between 60°F and 85°F. Planting can begin in June in most regions after frost danger has passed. In cooler northern areas, such as Zones 3-5, you can expect to plant bush varieties directly in the ground around mid-June, while southern Zones 6-10 can start as early as mid-May.

Beans improve soil health through nitrogen fixation, benefiting successive crops in the rotation. They prefer full sun and well-draining soil, but make sure to space them for good airflow to avoid disease. Keep an eye out for pests like beetles, which can chew on leaves, and provide support for pole varieties.

Peppers

Peppers, whether sweet or hot, prefer warmer climates with temperatures between 70°F and 85°F. For May-June planting in cooler northern regions (Zones 3-5), start seeds indoors around 8-10 weeks before the last frost; transplant them outdoors in mid to late June. In warmer Zones 6-10, you can directly plant seeds or put transplants in the garden from mid-May onwards.

Peppers require full sunlight and thrive in rich, loose soil. Regular watering and feeding with a balanced fertilizer promote healthy growth and fruit development. Different varieties like ‘Habanero’ or ‘Bell’ can yield bountifully, enhancing your summer culinary experiences.

Squash

Summer squash, including zucchini varieties, flourishes in temperatures between 70°F and 90°F. It can be directly seeded into the garden once the soil is consistently warm, typically by late May to early June in southern regions and mid-June in northern areas. Squash prefers full sun and rich, well-draining soil to support its vigorous growing habits.

Growth can be rapid, so be prepared to harvest frequently. Provide adequate space for sprawling vines, or consider vertical gardening techniques for smaller plots. Regular watering helps prevent blossom end rot—a common issue related to inconsistent moisture.

Corn

Sweet corn needs warm soil temperatures of at least 60°F to germinate successfully. Corn can be planted in late May in southern zones and by early June in northern regions. It thrives in full sun and well-drained, nutrient-rich soil, necessitating regular watering, especially when tasseling and setting ears.

Sweet corn matures in about 70 to 100 days, making it ideal for summer harvests. Plant in blocks rather than rows to improve pollination. Be sure to protect young seedlings from pests like corn earworms; monitoring and employing row covers can be effective strategies.

Carrots

Carrots prefer cooler soil temperatures, ideally ranging from 60°F to 75°F, making June the last chance to seed carrots for an autumn harvest. In northern regions, sow seeds in early June, while southern gardeners may start as late as mid-June. Carrots require loose, well-drained soil to grow straight and healthy, so it’s essential to prepare the beds thoroughly.

Keep the soil consistently moist until germination, which can take 2-3 weeks. Thin seedlings to ensure proper spacing for root development. Varieties like ‘Nantes’ or ‘Danvers’ are well-suited to summer planting, yielding sweet, crisp roots by late summer.

Basil

Basil thrives in the warm temperatures of summer, ideally between 70°F and 85°F. It can be directly seeded or transplanted from nurseries once nighttime temperatures stay consistently above 60°F—usually around mid to late June in northern zones. Basil prefers full sun and rich, well-draining soil.

Regular harvesting promotes bushy growth and robust flavor, and be mindful not to overwater, as basil is susceptible to root rot. This aromatic herb adds freshness to many culinary dishes, and varieties like ‘Genovese’ or ‘Thai’ can yield flavorful leaves throughout the summer.

Okra

Okra is a heat-loving plant that excels in temperatures from 75°F to 95°F. Directly plant seeds in warm soil in June after frost risks have passed, typically suitable for Zones 7-10. Northern gardeners should wait until soil temperatures are consistently warm.

Okra requires full sunlight and well-drained soil to grow robustly, reaching heights up to 4 feet. Regular watering is crucial during dry spells, and providing adequate spacing promotes good air circulation to prevent fungal diseases. Varieties like ‘Clemson Spineless’ are particularly popular due to their consistent production and tender texture when harvested young.

Melons

Melons thrive in warm temperatures between 70°F and 85°F, making June an excellent planting period. Sow seeds directly in loose, well-draining soil once nighttime temperatures remain above 60°F, usually from mid-May in southern regions and throughout June in northern areas.

Sugar-rich varieties like ‘Crimson Sweet’ (watermelon) and ‘Sugarcube’ (cantaloupe) require full sunlight with regular watering during fruit set to ensure sweetness. Mulching can help retain moisture in hot summer months and keep weeds at bay, speaking volumes for the health of these delicious summer fruits.
