This guide will focus on what to plant in June in Zone 10 when warm temperatures are conducive for vibrant growth.

Vegetables To Plant

June is an excellent time in Zone 10 to plant a diverse array of vegetables. Here are ten options, with detailed information regarding their temperature tolerances, ideal planting practices, and growth specifics.

Tomatoes

Temperature Tolerance: Tomatoes thrive in temperatures ranging from 70°F to 85°F but can endure heat up to 95°F with adequate watering.

Planting Dates: In Zone 10, tomatoes can be planted as early as mid-February through June.

Tomatoes are warm-season crops that require full sun for healthy growth. Start seeds indoors or purchase young plants. Space them about 18-24 inches apart to allow for air circulation and sunlight penetration. Tomatoes need consistent watering during dry spells but avoid wetting the foliage to minimize disease risk. For disease resistance, choose varieties like ‘Celebrity’ or ‘Better Boy.’ Supported by stakes or cages, these plants can yield fruit from summer into fall. Regularly inspect for pests, such as aphids or tomato hornworms, and ensure they receive sufficient nutrients for robust growth.

Peppers

Temperature Tolerance: Peppers are comfortable in temperatures from 70°F to 90°F and can tolerate some heat, though extreme heat can hinder fruit set.

Planting Dates: In Zone 10, peppers can be planted as soon as the soil temperature reaches 65°F, typically from late March to June.

Varieties include bell peppers, jalapeños, and serranos. They require full sun and should be spaced about 18 inches apart. Soil should be well-draining and rich in organic matter. Regular watering is crucial, especially during fruit development, but avoid overwatering which can lead to root rot. Fertilization with a balanced fertilizer can enhance growth. Harvest peppers before maturity for a milder taste or allow them to ripen on the plant for a sweeter flavor.

Cucumbers

Temperature Tolerance: Cucumbers thrive in warm weather with an optimum temperature range of 70°F – 95°F.

Planting Dates: Sow cucumber seeds directly in the garden from late March until mid-June.

Cucumbers are fast-growing vines that require full sunlight and moisture-retentive, well-drained soil. They can be grown on trellises to save space and allow for better air circulation, which helps prevent diseases such as powdery mildew. Plant cucumber seeds about an inch deep and two feet apart. It’s essential to water consistently, especially when fruiting begins, as inconsistent watering can cause bitterness. Harvest cucumbers regularly when they’re still young to encourage continuous production.

Squash

Temperature Tolerance: Squash prefers warmth, thriving best in temperatures between 70°F and 95°F.

Planting Dates: June is an optimal time to plant both summer and winter squash in Zone 10.

Summer squash (like zucchini) matures quickly, while winter squash (like butternut) takes longer. Space plants according to the variety’s growth habits; bush types need about two feet, while vining types require more room or a trellis. Plant in rich, well-draining soil, and water deeply, particularly during hot spells. Be on the lookout for pests such as squash bugs. Harvest summer squash when they are small for tenderness and winter squash once they’re fully mature and before frost.

Beans

Temperature Tolerance: Beans are happy in warm weather with an ideal range of 70°F to 90°F and can handle some heat.
