Introduction
June in USDA Hardiness Zone 10 presents an extraordinary opportunity for gardeners. While many regions across the country begin to wilt under summer heat, Zone 10’s unique climate allows for vibrant growth and diverse planting options. With average temperatures ranging from 70°F to 100°F, this warm subtropical zone creates ideal conditions for heat-loving plants to thrive.
This comprehensive guide will walk you through the best vegetables, flowers, herbs, and landscape plants to grow in June in Zone 10, with practical advice on planting techniques, growth requirements, and care tips to ensure your garden flourishes throughout the summer months and beyond.
Vegetables To Plant in June
The warm June temperatures in Zone 10 create perfect conditions for growing a variety of vegetables. Here are ten excellent options that will thrive in your summer garden:
1. Tomatoes
Temperature Tolerance: 70°F to 85°F (can endure up to 95°F with adequate watering)
Planting Dates: Mid-February through June
Tomatoes are quintessential summer vegetables that love the warm weather Zone 10 provides. For best results:
- Choose heat-resistant varieties like ‘Solar Fire’, ‘Heatwave II’, or ‘Sun Master’ for Zone 10’s summer temperatures
- Plant in full sun, spacing plants 18-24 inches apart for proper air circulation
- Install support systems (stakes or cages) at planting time to avoid root damage later
- Water deeply at the soil level, avoiding foliage to prevent disease
- Apply a 2-3 inch layer of organic mulch to maintain soil moisture and temperature
- Monitor for pests like aphids, whiteflies, and tomato hornworms regularly
Pro Tip: For late-season planting in June, select early-maturing varieties (60-70 days) to ensure a harvest before fall temperatures arrive.
2. Peppers
Temperature Tolerance: 70°F to 90°F
Planting Dates: Late March to June (when soil temperature reaches 65°F)
Peppers thrive in Zone 10’s summer heat, offering varieties from sweet bells to fiery hot peppers:
- Space plants 18-24 inches apart in nutrient-rich, well-draining soil
- Provide consistent moisture, particularly during fruit development
- Side-dress with compost or balanced organic fertilizer when flowering begins
- Consider afternoon shade in the hottest locations to prevent sunscald on fruits
- Harvest sweet peppers when they reach full size but are still firm; hot peppers can be harvested at any stage depending on desired heat level
Recommended Varieties: ‘California Wonder’ (bell), ‘Anaheim’ (mild), ‘Early Jalapeño’ (medium heat), and ‘Thai Bird’ (very hot) all perform well in Zone 10’s summer conditions.
3. Cucumbers
Temperature Tolerance: 70°F to 95°F
Planting Dates: Late March until mid-June
Cucumbers grow rapidly in warm weather, making them perfect for June planting:
- Direct sow seeds 1 inch deep and 2-3 feet apart
- Train vines on trellises to save space and improve air circulation
- Water deeply and consistently (1-2 inches per week) to prevent bitter-tasting fruits
- Harvest frequently when cucumbers are still young and tender (generally 6-8 inches long for slicing varieties, 3-4 inches for pickling types)
- Choose heat-tolerant varieties like ‘Armenian’, ‘Beit Alpha’, or ‘Suyo Long’ for summer planting
Companion Plants: Grow alongside sunflowers, corn, or trellised beans for natural shade during the hottest part of the day.
4. Squash
Temperature Tolerance: 70°F to 95°F
Planting Dates: March through June
Both summer and winter squash varieties thrive in Zone 10’s June heat:
- Create planting mounds enriched with compost, spacing 3-4 feet apart
- Plant 4-5 seeds per mound, thinning to the strongest 2-3 seedlings
- Water deeply at the base of plants, avoiding foliage
- Monitor for squash vine borers and squash bugs, which are common in warm weather
- Harvest summer squash (zucchini, yellow squash) when young and tender
- Allow winter squash (butternut, acorn, spaghetti) to fully mature on the vine until the skin hardens
Pollination Tip: Plant flowering herbs or annuals nearby to attract pollinators, ensuring better fruit set.
5. Beans
Temperature Tolerance: 70°F to 90°F
Planting Dates: Late March to June
Beans are fast-growing, nitrogen-fixing plants perfect for summer gardens:
- Direct sow seeds 1 inch deep, 2-4 inches apart

Tips for Summer Planting Success in Zone 10
To ensure your June plantings thrive despite the summer heat:
Watering Strategies
- Water deeply and less frequently rather than shallowly and often to encourage deep root growth
- Apply water in the early morning to minimize evaporation and fungal disease
- Consider drip irrigation for efficient water delivery directly to plant roots
- Use moisture meters to avoid both over and under-watering
- Group plants with similar water needs together for efficient irrigation
Mulching Benefits
- Apply 2-3 inches of organic mulch around plants (keeping it away from stems)
- Replenish mulch as it decomposes to maintain soil temperature regulation
- Consider light-colored mulches in extremely hot areas to reflect heat
- Use coconut coir or pine straw for water retention in sandy soils
- Apply compost as mulch to improve soil quality as it breaks down
Shade Protection
- Provide afternoon shade for sensitive plants using shade cloth (30-50%)
- Plant tall crops like corn or sunflowers on the west side of heat-sensitive plants
- Use row covers to protect seedlings during establishment
- Consider temporary shade structures during extreme heat events
- Plant near existing trees for natural filtered light (being mindful of root competition)
Soil Care
- Add organic matter before planting to improve water retention and drainage
- Avoid disturbing soil during extreme heat to prevent moisture loss
- Consider using water-retaining polymers in container plantings
- Test soil pH and adjust according to plant needs
- Apply compost tea monthly to boost soil microorganism activity
Pest Management
- Monitor for pests regularly, as hot weather can increase insect populations
- Use lightweight row covers to protect vulnerable crops from insects
- Introduce beneficial insects like ladybugs and lacewings for natural pest control
- Apply organic pest controls in the evening to prevent leaf burn
- Remove severely infested plants promptly to prevent spread
Conclusion
June in Zone 10 offers exceptional opportunities for gardeners. By selecting the right plants and providing appropriate care, you can create a thriving garden landscape despite the summer heat. Focus on heat-loving varieties, proper watering techniques, and strategic planting locations to maximize success.
Whether you’re growing vegetables for your table, flowers for color and pollinators, herbs for culinary use, or landscape plants for long-term beauty, June planting in Zone 10 allows you to garden productively year-round.
