What to Plant in June: A Zone-by-Zone Guide for Vegetable Gardeners

June can feel like a lot is happening all at once in the garden. Some crops are still going in the ground, others are wrapping up, and if you’re paying attention, you’re already thinking about fall.

This guide breaks down what to plant in June by USDA hardiness zone. Whether you’re in a short northern season or a long southern one, there’s something productive to be doing this month.

We’ve separated outdoor direct sowing from indoor seed starting so you know exactly where each crop belongs.

How to Use This Guide

June planting looks very different depending on where you live. A gardener in Minnesota is racing to get warm-season crops in before summer slips away. A gardener in Texas is shifting focus to fall and thinking about what to start indoors now.

Find your USDA zone below. If you’re not sure of your zone, check the USDA Plant Hardiness Zone Map. Zones are grouped here to keep things practical.

Each section lists crops for direct sowing outdoors and crops worth starting indoors for a later transplant.

Zones 3–4: Make Every Warm Week Count

June is prime planting time in cold-climate zones. Frost risk is finally low, and the soil has warmed enough for heat-loving crops to take off.

Direct sow everything you can right now. Your growing window is shorter than most, so getting seeds in the ground quickly matters more here than anywhere else.

For more detail on seed starting timing in these zones, see our guides on When to Start Seeds in Zone 4b and Zone 4a.

Zones 5–6: Full Speed on Warm-Season Crops

Zones 5 and 6 hit their stride in June. The last frost is well behind you, and days are getting long. This is the sweet spot for filling beds with warm-season vegetables.

You can still get a solid harvest from crops planted now, but don’t wait too long. Late June sowings of long-season crops may struggle to finish before fall.

Zones 7–8: Warm-Season Crops and Fall Planning

By June in zones 7 and 8, the summer garden is well underway. You’re likely already harvesting some things. But June is also the time to start thinking ahead to fall.

Early June is your last realistic window for warm-season direct sowing. Late June is when smart gardeners start fall brassicas indoors.

Zones 9–10: Focus Shifts to Fall

In zones 9 and 10, June heat is serious. Most warm-season crops that aren’t already in the ground will struggle to get established now.

The smart move in June here is starting fall and winter crops indoors where they’re protected from the heat. You’ll transplant them out in late summer or early fall.

For more tailored timing in these zones, our guides on When to Start Seeds in Zone 9b cover this in more detail.

Zone 11 and Above: Year-Round Considerations

If you’re gardening in zone 11 or higher, your planting calendar works differently than most. June is hot and often humid, but with the right crops, you can keep the garden productive.

Heat-tolerant crops like okra, sweet potatoes, and tropical herbs do well direct sown now. Fall planning is also very much in play, with brassicas and root vegetables coming in late summer.

• Direct sow: okra, sweet potatoes, tropical herbs, yard-long beans
• Start indoors: tomatoes, peppers, eggplant for a fall planting cycle
• Avoid: cool-season crops until temperatures drop significantly

A Few Crops That Work Almost Everywhere in June

No matter where you garden, a handful of crops can go in the ground in June across most of the country. These are reliable picks for filling gaps in the garden.

• Beans: Fast-growing and heat-tolerant. Direct sow in zones 3–8, early June only in zones 9+.
• Cucumbers: Love warm soil and long days. A June sowing works well through zone 8.
• Summer squash: Quick to produce and easy from seed. Works in all zones through 8 in early June.
• Basil: Direct sow once nights stay above 50°F. Perfect for June almost everywhere.
• Beets: Can handle light heat in cooler zones. Direct sow in zones 3–6 for a summer or fall harvest.

Frequently Asked Questions

Is it too late to plant tomatoes in June?

In zones 3–6, you can still transplant tomato seedlings in early June if your last frost has passed. Direct sowing tomatoes outdoors in June is too late for most northern zones. In zones 7–9, early June transplants are fine.

Can I plant lettuce in June?

Lettuce bolts quickly in June heat. In zones 3–5, you can still sow it early in the month. In warmer zones, wait until late summer to start lettuce for a fall crop. Heat-tolerant varieties like Jericho or Concept handle summer better than others.

What vegetables can I still direct sow in June?

Beans, cucumbers, summer squash, zucchini, beets, and carrots are all solid June direct-sow options in most zones. Corn works too if you’re in zones 5–7 and act in early June.

Should I be starting fall crops indoors in June?

Yes, especially if you’re in zones 6 and warmer. Brassicas like broccoli, cabbage, and cauliflower benefit from being started indoors in late June so they’re ready to transplant in late summer when conditions cool down.

What should I not plant in June?

Avoid sowing cool-season crops like spinach, peas, and most lettuces outdoors in June in zones 6 and warmer. They’ll bolt or struggle in the heat. Save those for late summer starts instead.
