What to Plant in July by Zone

Here’s what you can still plant in July, broken down by region and zone—with specific variety suggestions to keep things simple and reliable.

Zones 3–4 (Short-Season Northern Areas)

Focus on the fastest maturing crops and look for varieties that can tolerate a bit of chill if frost comes early.

  • Bush Beans:
    • Contender Bush Bean – 40–55 days. Great for cool nights. Tender and stringless with heavy yields.
    • Topcrop – 50 days. Reliable early bush bean with upright plants and high yield. In Zones 3–4, it can still be planted in mid-July. Sow as early in the month as possible, and consider using row cover or a low tunnel to help ensure it reaches maturity before frost.
    • Tendergreen Improved – 45–56 days. Strong heat-tolerant option with rich flavor and resistance to common bean viruses. It’s a good option, but make sure to sow it early enough to mature before fall frost. A row cover or low tunnel can help extend the season by a few weeks if frost threatens before harvest.
  • Summer Squash:
    • Early Prolific Straightneck Squash – 45-55 days. Dependable and fast; pick young for tender fruit. These can still be planted in Zones 3–4, but timing is critical. Keep an eye on frost dates, and consider row cover or low tunnels in early fall if needed.
    • Early Summer Crookneck Squash – 50–55 days. Classic yellow crookneck with excellent flavor. Like other summer squash, this can still be planted in Zones 3–4 if started early enough. Watch for frost in fall and use row cover if needed.
    • White Bush Scallop – 50 days. Unique shape and good productivity in hot weather. Timing is key—plant in early-mid July and consider frost protection to ensure a full harvest.
  • Cucumbers:
    • Boston Pickling Cucumber – 50–60 days. Prolific and fast-maturing; good for fresh eating or pickling. These can still be planted in Zones 3–4, but frost may come before they finish. For best results, sow early and consider frost protection like row cover in the fall.
    • White Wonder Cucumber – 55–60 days. Creamy white skin and crisp texture, excellent for slicing. Timing is tight in Zones 3–4—plant early to mid July and monitor frost forecasts. Row covers or low tunnels may be needed to bring the crop to full maturity.
    • National Pickling Improved Cucumber – 50–55 days. Excellent for quick pickles and steady yields. Like others, it’s possible in Zones 3–4, but frost protection may be needed to finish the crop.
  • Leafy Greens:
Black Seeded Simpson Lettuce with tender, light-green leaves—ideal to plant in July for fast, fresh greens.

Note: Even heat-tolerant lettuces like Black Seeded Simpson and Simpson Elite can bolt quickly during unexpected heat waves. In Zones 3–4, consider planting in partial afternoon shade, near taller crops, or in cooler microclimates to help slow bolting and extend your harvest.

Tips for Success:

Extra July Gardening Tips

1. Water Deeply and Consistently:
July is hot. Keep soil moisture even to avoid stress and bitterness in leafy crops. Water early in the day to reduce evaporation and fungal issues.

2. Mulch Matters:
A thick layer of mulch (straw, shredded leaves, or grass clippings) keeps roots cool and holds in moisture—especially critical for tender greens and newly-sown beans.

3. Use Shade Wisely:
In very hot climates, planting greens near taller crops or using lightweight shade cloth can extend your growing window.

4. Fertilize Lightly:
Warm-season crops grow quickly, but don’t overdo nitrogen—too much leads to lush leaves and no fruit. A balanced fertilizer or compost tea every few weeks is often enough.

5. Succession Planting Works:
For crops like bush beans, cucumbers, and greens, sow a second or third round in late July or early August for continuous harvests through early fall.

6. Prepare for Fall While You Harvest Summer Crops:
In Zones 7–9, you can start preparing for fall brassicas (like cabbage and broccoli) by starting seeds indoors in late July. Transplant them in mid to late August for a fall crop.


Final Word

July gardening is all about quick decisions and faster crops. When you plant in July, choosing fast-maturing heirloom varieties gives you a solid chance to enjoy fresh beans, squash, cucumbers, and greens before frost hits. With careful soil prep, smart watering, and a layer of mulch, your garden can still thrive. Even if you plant in July a bit later than planned, thoughtful shading and consistent care help ensure a strong summer finish.

FAQ:

Can I really plant vegetables in July and still get a harvest before frost?

Yes! In USDA Zones 3 through 9, July is still a viable planting window for many fast-growing heirloom varieties. With warm soil and long daylight hours, crops like bush beans, cucumbers, summer squash, and greens can still mature before the season ends—especially if you plant early in the month.

What are the best vegetables to plant in July for Zone 3 or 4?

Focus on quick-maturing crops like Contender Bush Beans, Early Prolific Straightneck Squash, and Boston Pickling Cucumbers. Start them as early in July as possible, and consider using row covers or low tunnels to extend your harvest window before frost.

Is it too late to plant cucumbers in mid-summer?

Not at all—varieties like Boston Pickling and National Pickling Improved mature in about 50–60 days and do well when planted in July. However, in Zones 3–4, you’ll want to plant early in the month and keep row covers handy in case of early frost.

Which bush beans are best for a July planting?

Top choices include Contender, Topcrop, Blue Lake 274, and Provider. These varieties mature in 40–60 days, thrive in warm soil, and can often be succession planted for staggered harvests through early fall.

What are good summer squash choices for a late start?

Quick-growing varieties like Early Prolific Straightneck, Golden Zucchini, and White Bush Scallop are excellent for July planting. Most mature in 45–60 days and produce heavily in warm conditions.

Can I plant leafy greens like lettuce or spinach in July?

Yes, but choose heat-tolerant varieties such as Black Seeded Simpson Lettuce, Simpson Elite, and Giant Nobel Spinach. In hotter areas, provide afternoon shade or plant near taller crops for better success.

What can Zone 9 gardeners still plant in July?

Zone 9 gardeners can grow heat-loving crops like Clemson Spineless Okra, Cow Horn Okra, Black Beauty Zucchini, and Purple Hull Pinkeye Cowpeas. Fast-maturing winter squash like Delicata also perform well if planted in early July.

How can I protect July plantings from summer heat or early frost?

Use row covers, low tunnels, or lightweight shade cloth depending on your region. In northern zones, these protect from early frost. In southern zones, they help cool tender greens during peak summer heat.

Is fertilizing important for July-sown vegetables?

Yes, but go light. Use balanced fertilizers or compost tea every couple of weeks. Avoid too much nitrogen, which encourages leafy growth at the expense of fruit and root development.

Can I plant a second round of crops in late July or August?

Absolutely. This is called succession planting. Crops like bush beans, cucumbers, and leafy greens can be planted again for an extended harvest, especially in Zones 5–9 where the growing season is longer.

      J.M.J.
      Hi Katie,

      Thank you for your question. Here’s more info to help with perennial flowers in July:

      Most of Indiana falls into USDA Hardiness Zones 5b through 6b, so planning for zone 5–6 conditions is spot on. July can actually be a great time to establish many potted or container‑grown perennials, as long as you keep them well‑watered through their first few weeks. Here are some reliable, bloom‑worthy perennials you can plant right now:

      Echinacea (Coneflower)

      Zones 3–9, drought‑tolerant once established

      Loves full sun and well‑drained soil

      Blooms midsummer into fall; excellent for cutting and pollinators

      Rudbeckia (Black‑eyed Susan)

      Zones 3–9; tough and long‑blooming

      Thrives in full sun; tolerates light shade

      Seedheads provide winter interest if you leave them standing

      Daylilies (Hemerocallis)

      Zones 3–9; extremely adaptable

      Plant divisions or potted fans in sun to part shade

      Water deeply twice a week until roots take hold

      Sedum (‘Autumn Joy’ and other stonecrops)

      Zones 3–9; succulent foliage resists drought

      Full sun; sandy or average soils

      Late‑season flowers attract butterflies

      Coreopsis (Tickseed)

      Zones 4–9; self‑seeding in good light

      Prefers full sun and well‑drained soil

      Deadhead spent blooms to prolong flowering

      Salvia (Perennial sage)

      Zones 4–8; heat‑loving and deer‑resistant

      Full sun; average to dry soils

      Spikes of purple, red, or blue blooms midsummer

      Phlox paniculata (Garden phlox)

      Zones 4–8; fragrant, tall flower clusters

      Prefers rich, moist soil and full sun

      Watch for mildew—ensure good air circulation

      Asters (New England or New York aster)

      Zones 4–8; ideal for late‑season color

      Full sun; moist, well‑drained soil

      Divide crowded clumps in fall or early spring

      Heuchera (Coral bells)

      Zones 4–9; grown more for foliage but also bloom

      Part shade to sun (in cooler spots); rich soil

      Keep evenly moist until established

      Baptisia (False indigo)

      Zones 3–8; deep taproots once mature—no transplanting later!

      Best planted now as potted stock; full sun

      Blue‑purple pea‑type flowers in late spring

      Planting Tips for July

      Prep the soil by working in plenty of compost or aged manure to improve moisture retention.

      Water deeply at planting and keep a twice‑weekly watering schedule (more often if you get less than an inch of rain).

      Mulch with 2–3 inches of organic material (bark, straw, or shredded leaves) to keep roots cool and soil moist.

      Pinch back or shear spent flower stems on blooms like salvia and coreopsis to encourage a flush of rebloom.

      Watch the heat—if you have a heat wave, consider temporary afternoon shade (a light fabric or dappled canopy) until plants acclimate.

      With consistent moisture and good soil preparation, these perennials will settle in now and reward you with stronger, fuller displays next spring.

      Hi Joan,

      Thanks so much for your comment. Yes, totally, we know many great people in “Commiefornia”, as you call it. Beautiful state, and much good still there, praise God!

      Great question! You’re totally right, we missed Zone 10 (Southern Florida, parts of Southern California, southernmost Texas, etc.), which has a very different planting calendar because it stays warm year-round — but mid-summer planting in July is often not ideal for many crops.

      ️ Zone 10 in July: What You Can Plant

      In July, it’s usually too hot and humid for most vegetables to thrive unless you’re focusing on:

      Heat-lovers that handle extreme temps

      Prep for fall planting, including seed starting indoors

      Cover crops or soil recovery

      Possible to Sow in July:

      Okra: Clemson Spineless, Burgundy, Emerald

      Southern Peas: California Blackeye #5, Purple Hull Pinkeye

      Sweet Potatoes: Slips planted now will do well before fall

      Yardlong Beans (Asparagus Beans): Grow well in heat and humidity

      Hot Peppers: Can still be started from transplants

      Eggplant: Heat-tolerant varieties like Black Beauty may still do okay

      Roselle (Florida Cranberry): Tropical hibiscus used in teas — loves July heat

      Malabar Spinach: Not a true spinach, but grows fast in heat and humidity

      Avoid Planting in July:

      Leafy greens (except tropical ones like Malabar spinach)

      Most cucurbits (melons, squash, cukes) unless you provide ample shade and pest control

      Beans and tomatoes often struggle unless planted earlier

      Tips for Zone 10 July Gardening

      Shade cloth is essential for success with most crops.

      Mulch deeply to retain soil moisture and protect roots.

      Start fall crops indoors or in shaded seedling beds — August and September are your prime transplanting windows.

      Monitor for pests constantly — aphids, whiteflies, spider mites thrive now.

      We hope this helps! Thanks again for bringing this to our attention. 🙂 Thank you for your patronage, and God bless and keep you,
      John, Sarah, and Family
