What to Plant in July: Fall Garden Starts and Heat-Tolerant Crops

July is a strange month for gardeners. Northern gardens are in peak production; southern gardens are barely hanging on through 95°F days. But in every zone, July is the month fall gardens get started. Miss the July window and you’re stuck with empty beds from September through the first frost.

Here’s what to plant in July, zone by zone, with a focus on the fall crops that matter most.

Zones 3-4: Still Planting Summer Crops

First frost: September 1–15

In the coldest zones, July is your last real planting window before the days start getting noticeably shorter. The focus is on quick-maturing varieties that can finish before September’s first frost.

Direct sow early July (if not already in):

• Bush beans (60-day varieties)
• Carrots, beets, radishes — fall harvest
• Lettuce, spinach (in a cool, shaded spot)
• Fast-maturing corn (if you started late)

Start indoors:

• No fall brassicas — your season is too short to justify the effort in zones 3-4
• Focus on extending current crops with row cover instead

Maintenance focus:

• Stake everything — summer storms can take out a tomato in one gust
• Side-dress tomatoes and squash with compost or a balanced fertilizer

Pro tip: Count backward from your first frost date. If a variety says “70 days to maturity,” you need 70 days from direct-sow date to harvest — plus an extra 10-14 days as a buffer for slower growth in cooler fall weather.

Zones 5-6: Fall Garden Starts Now

First frost: September 15 – October 15

July in zones 5-6 is the pivot point from spring/summer garden to fall garden. Start fall brassicas indoors now for August transplant — miss this window and you lose the fall harvest.

Start indoors (for August transplant):

• Broccoli, cauliflower, cabbage, Brussels sprouts
• Kale, collards
• Kohlrabi

Direct sow:

• Bush beans (succession, 55-60 day varieties)
• Carrots, beets, turnips, radishes — fall harvest
• Cucumbers, summer squash (second planting for September harvest)

Late-July direct sow:

• Spinach, lettuce (in cooler, shaded beds)
• Chinese cabbage, bok choy
• Cilantro (it will stop bolting as days shorten)

Harvest and preserve:

• Garlic and shallots are done — cure in a dry, shady spot
• Summer squash is in glut mode — harvest every 2-3 days and freeze or give away

Pro tip: Brassicas started in summer heat need shade. Use a board or shade cloth over the seedling tray until germination, then 30% shade until they’re transplanted.

Zone 7: Transition Month

First frost: October 15 – November 1

Zone 7 gets two distinct gardens — summer and fall — and July is the month they overlap. Summer crops are producing heavily while fall crops get started.

Start indoors:

• Tomatoes — fall transplants go in August for October harvest in the South
• Peppers, eggplant (for September transplant)
• Broccoli, cauliflower, cabbage, Brussels sprouts

Direct sow:

• Bush beans (55-day varieties for September harvest)
• Second plantings of cucumbers, summer squash
• Carrots, beets for fall
• Fall corn (80-day varieties at the latest)

Late-July direct sow (cooler parts of zone 7):

• Bok choy, Chinese cabbage, mustard greens
• Radishes, turnips

Pest and disease:

• Squash vine borer damage peaks now — remove infected plants immediately
• Tomato foliar disease (early blight, septoria) — prune lower leaves, mulch, water at soil level

Pro tip: Fall tomatoes need to be in the ground by August 15 in most of zone 7 to fruit before frost. If you’re starting seeds in July, pick determinate varieties — they set fruit faster and finish before cold arrives.

Zones 8-9: Full-On Fall Planning

First frost: November 1 – December 15

July in zones 8-9 is primarily a management month — keep summer crops alive through the heat, and plan the fall garden in detail. Most actual planting starts in August, but July is when you order seeds and start the heat-tolerant fall transplants.

Start indoors (in air conditioning):

• Tomatoes, peppers, eggplant for August/September transplant
• Broccoli, cauliflower, cabbage
• Lettuce, kale (seedlings wilt in direct heat — use shade)

Direct sow:

• Okra, southern peas, yard-long beans — last call
• Sweet potato slips (if you haven’t already)
• Pumpkins for Halloween — must go in by mid-July

Heat survival:

• Shade cloth (40-50%) over everything that isn’t okra or peppers
• Deep morning watering only
• Pull anything that’s clearly done — bolting lettuce, exhausted spring squash

Pro tip: Order fall seeds in early July. By August the good seed companies are sold out of the popular varieties (especially tomato and pepper seeds), and you’ll be stuck with what’s left.

Zone 10: Hurricane Prep and Heat

First frost: rarely freezes

Zone 10 in July is about making it through peak hurricane risk and extreme heat. Planting continues but in a narrower variety set.

Plant now:

• Sweet potatoes, yard-long beans, southern peas
• Okra (still great), hot peppers
• Calabaza, chayote, luffa
• Tropical herbs: lemongrass, ginger, turmeric, culantro

Pause on:

• Tomatoes (restart in September)
• Most lettuce and spinach (Malabar spinach is the exception)

Storm prep:

• Stake and secure trellises
• Harvest anything ripe — hurricanes will strip fruit
• Clear debris from around the garden

Pro tip: Florida and Caribbean gardeners often have a better fall/winter garden than summer. Plan September-through-February crops seriously — cool-season lettuce, brassicas, and tomatoes thrive then.

July Planting Checklist

Universal July tasks no matter where you garden:

1. Start fall crops indoors — brassicas, lettuce, and fall tomatoes all start indoors in July in most zones
2. Harvest aggressively — squash, beans, cucumbers, and okra produce more when picked frequently
3. Side-dress heavy feeders — tomatoes, peppers, corn, squash benefit from mid-season compost or fish emulsion
4. Mulch and water deeply — July heat punishes shallow roots
5. Order fall seeds now — delays mean sold-out varieties by August
6. Log and photograph — end-of-season data starts building now
