Florida gardeners planting in June should prioritize vegetables that tolerate humidity and resist common southern pests and diseases. Finding the best vegetables to plant in June in Florida means choosing heat-loving crops that thrive when temperatures regularly hit 90°F. Your summer garden can still produce heavily if you pick the right varieties and follow a few key timing rules.
June is actually a prime month for many warm-season vegetables in Florida. The key is knowing which ones handle the intense sun, afternoon thunderstorms, and persistent insects like whiteflies and hornworms. Below is your complete guide to what works and what to skip.
Best Vegetables To Plant In June In Florida
This list focuses on crops that germinate quickly in hot soil and produce before fall cool-down. Each selection has been tested by Florida gardeners through humid summers.
Southern Peas (Cowpeas)
Southern peas are practically bulletproof in June. They laugh at heat, fix nitrogen in your soil, and need almost no care once established.
- Varieties: Blackeye, Purple Hull, Cream 40
- Planting depth: 1 inch
- Days to harvest: 60-70
- Spacing: 4 inches apart in rows 3 feet apart
These peas actually produce better in hot weather than in spring. They resist most pests and only need water during dry spells.
Okra
Okra is the quintessential Florida summer vegetable. It thrives on heat and keeps producing until frost.
- Varieties: Clemson Spineless, Emerald, Burgundy
- Planting depth: 1/2 inch
- Days to harvest: 50-60
- Spacing: 12 inches apart
Soak seeds overnight before planting to speed germination. Okra pods get tough quickly, so harvest every 2-3 days when they are 2-3 inches long.
Sweet Potatoes
June is the perfect time to plant sweet potato slips in Florida. They need 90-120 days of warm weather, which you have plenty of.
- Varieties: Beauregard, Covington, Centennial
- Planting depth: Bury slips up to the leaves
- Days to harvest: 90-120
- Spacing: 12-18 inches apart in ridges
Sweet potatoes are drought-tolerant once established. They also suppress weeds with their dense vine growth.
Summer Squash And Zucchini
These fast growers can be planted in June, but you must watch for squash vine borers. Use row covers or plant resistant varieties.
- Varieties: Yellow Crookneck, Zephyr, Tatume
- Planting depth: 1 inch
- Days to harvest: 45-55
- Spacing: 24 inches apart
Plant in mounds to improve drainage. Harvest when fruits are 6-8 inches long for best flavor and texture.
Long Beans (Yardlong Beans)
Regular green beans struggle in June heat, but long beans love it. They produce heavily through summer.
- Varieties: Red Noodle, Asparagus Bean
- Planting depth: 1 inch
- Days to harvest: 60-80
- Spacing: 6 inches apart along a trellis
These beans need support to climb. Pick them when they are pencil-thin for tender eating.
Malabar Spinach
Regular spinach bolts immediately in June. Malabar spinach is a heat-loving vine that produces tender leaves all summer.
- Planting depth: 1/2 inch
- Days to harvest: 70-85
- Spacing: 12 inches apart
This is not true spinach but tastes similar when cooked. It grows vigorously up trellises or fences.
Peppers (All Types)
June-planted peppers will produce until November in Florida. They need heat to set fruit properly.
- Varieties: Bell, Jalapeño, Cubanelle, Habanero
- Planting depth: Same depth as nursery pot
- Days to harvest: 60-90 from transplant
- Spacing: 18 inches apart
Use transplants rather than seeds for faster harvests. Peppers benefit from afternoon shade in extreme heat.
Eggplant
Eggplant loves Florida summers. It produces steadily through the hottest months.
- Varieties: Black Beauty, Ichiban, Rosa Bianca
- Planting depth: Same depth as nursery pot
- Days to harvest: 65-80 from transplant
- Spacing: 24 inches apart
Harvest when fruits are glossy and before seeds turn brown. Eggplant needs consistent watering to prevent bitter fruit.
What NOT To Plant In June In Florida
Some vegetables simply cannot handle June heat and humidity. Avoid these until September or October.
- Tomatoes (most varieties stop setting fruit above 90°F)
- Lettuce and leafy greens (bolt immediately)
- Broccoli and cauliflower (require cool nights)
- Peas (English and snow peas need cool weather)
- Carrots (germination fails in hot soil)
If you really want tomatoes, try heat-set varieties like Heatmaster or Solar Fire, but expect lower production.
How To Prepare Your Florida Garden For June Planting
Success with June planting depends on soil preparation and timing. Follow these steps for best results.
Step 1: Improve Soil Drainage
Florida summer rains can drown roots. Raise beds or add organic matter to improve drainage.
- Mix 3-4 inches of compost into existing soil
- Create raised rows 6-8 inches high
- Add sand to heavy clay soils
Step 2: Use Shade Cloth
Many vegetables benefit from 30-40% shade cloth during June afternoons. This reduces heat stress and prevents sunscald.
- Install shade cloth on hoops or frames
- Remove cloth when temperatures drop below 85°F
- Use white cloth to reflect heat
Step 3: Water Deeply And Consistently
June heat evaporates water quickly. Drip irrigation is best for Florida gardens.
- Water early morning between 6-8 AM
- Avoid overhead watering to prevent fungal diseases
- Mulch with straw or pine bark to retain moisture
Step 4: Manage Pests Proactively
Florida summer pests are relentless. Use these strategies before problems start.
- Apply neem oil weekly for whiteflies and aphids
- Use Bacillus thuringiensis (Bt) for caterpillars
- Plant marigolds and basil as companion plants
- Inspect leaves daily for eggs and damage
Best Varieties For Florida June Planting
Choosing the right variety is critical. Standard northern varieties often fail in Florida conditions.
Heat-Tolerant Tomato Varieties
If you must plant tomatoes in June, choose these heat-set types.
- Heatmaster
- Solar Fire
- Florida 91
- Phoenix
These varieties set fruit even when night temperatures stay above 75°F.
Disease-Resistant Squash
Powdery mildew and vine borers are common. Look for these resistant types.
- Tatume (resistant to borers)
- Zephyr (tolerates humidity)
- Yellow Crookneck (good air circulation)
Humidity-Loving Beans
Standard bush beans rot in June humidity. Choose these instead.
- Yardlong beans (Red Noodle)
- Rattlesnake pole beans
- Contender bush beans (tolerates heat)

Problem: Blossom Drop On Peppers And Squash
High humidity prevents pollination. Solution: Hand pollinate in early morning.
- Use a small paintbrush to transfer pollen
- Gently shake plants to release pollen
- Provide air circulation with fans
Problem: Powdery Mildew On Leaves
Humidity promotes fungal growth. Solution: Use milk spray or sulfur.
- Mix 1 part milk with 9 parts water
- Spray leaves weekly in morning
- Remove infected leaves immediately
Frequently Asked Questions About June Planting In Florida
Can I Plant Tomatoes In June In Florida?
Yes, but only heat-set varieties like Heatmaster or Solar Fire. Standard tomatoes stop setting fruit above 90°F. Expect lower yields than spring planting.
What Is The Fastest Growing Vegetable To Plant In June In Florida?
Summer squash and zucchini produce in 45-55 days. Okra also grows quickly once soil warms. Southern peas are ready in 60 days.
Should I Use Fertilizer For June-planted Vegetables?
Yes, but use slow-release or organic fertilizers. Fast-release nitrogen burns roots in hot soil. Apply compost tea monthly for steady nutrition.
How Often Should I Water My June Garden In Florida?
Water deeply 2-3 times per week, not daily. Shallow watering encourages weak roots. Check soil moisture 2 inches down before watering.
Can I Grow Cucumbers In June In Florida?

Final Tips For Florida June Garden Success
Your June garden can be productive if you work with Florida’s climate, not against it. Focus on vegetables that evolved in hot, humid conditions. Southern peas, okra, sweet potatoes, and long beans are your safest bets.
Use raised beds to improve drainage during rainy periods. Install shade cloth for afternoon protection. Water deeply but infrequently to encourage deep root growth. Monitor daily for pests and diseases, treating early before problems spread.
Remember that June planting sets you up for a fall harvest of many crops. Sweet potatoes planted now will be ready in September. Peppers and eggplant will produce until November. Okra keeps going until first frost.
Dont be afraid to experiment with one or two new varieties each year. Florida’s diverse microclimates mean what works in Miami might fail in Tallahassee. Keep notes on what performs best in your specific location.
Your June garden may look different from a spring garden, but it can be just as rewarding. The key is choosing the best vegetables to plant in June in Florida and giving them the care they need to thrive through the hottest months. With proper planning, you will harvest fresh vegetables all summer long.
