June hits different in the garden. The soil is finally warm, the days are long, and everything you planted in April and May is starting to show real progress. But here's the thing most planting calendars won't tell you: what to plant in June varies wildly depending on where you live. A gardener in Zone 4 Minnesota is just getting warm enough for heat-lovers, while someone in Zone 9 Phoenix is already strategizing around triple-digit afternoons. This june planting guide breaks it all down — zone by zone, crop by crop — so you plant the right things at the right time, no matter where you garden.
Whether you're succession planting your third round of bush beans or finally transplanting those pepper starts you've been babying since March, June is one of the most productive planting months of the year. Let's get into what goes in the ground right now.
What to Plant in June: Understanding Your Zone
Before you grab a single seed packet, you need to know your USDA Hardiness Zone. It's the single biggest factor in what to plant in june and when. Here's how June breaks down across the country:
Zones 3–4: The Late Starters
If you garden in Zones 3 or 4 — think northern Minnesota, Montana, parts of Maine — June is your real spring. Your last frost date likely fell somewhere in late May, which means the soil is just now hitting the 60°F (15°C) threshold that warm-season crops demand.
Plant now:
- Direct-sow bush beans (Phaseolus vulgaris), cucumbers (Cucumis sativus), and summer squash (Cucurbita pepo) in early June once soil temps are consistently above 60°F (15°C)
- Transplant tomatoes, peppers (Capsicum annuum), and eggplant (Solanum melongena) — but keep row covers handy for cold snaps
- Direct-sow sweet corn (Zea mays) varieties with short days-to-maturity (70–80 days) like 'Early Sunglow'
- Plant potatoes if you haven't already — mid-season varieties like 'Yukon Gold' still have time
Pro tip: In these zones, every day counts. Use black plastic mulch or dark landscape fabric to pre-warm beds a week before planting. It can raise soil temperature by 5–10°F (3–5°C), which makes a real difference for germination rates.
Zones 5–6: Peak Planting Season
Zones 5 and 6 — the Midwest, mid-Atlantic, parts of the Pacific Northwest — are in the sweet spot. Last frost is well behind you, soil is warm, and you've got months of growing season ahead. This is arguably the best june planting window in the country.
Plant now:
- Succession-sow beans every 2–3 weeks for continuous harvest through September
- Direct-sow cucumbers, squash, melons (Cucumis melo), and pumpkins (Cucurbita maxima)
- Transplant peppers, eggplant, and any remaining tomato starts
- Start fall brassicas indoors — broccoli and cauliflower seeds started now will be ready to transplant in July for fall harvest
- Plant sweet potato slips (Ipomoea batatas) — they need warm soil and a long season, and early June is ideal
Zones 7–8: Summer Vegetables to Plant Before the Heat
In Zones 7 and 8 — the Southeast, Texas, parts of the Southwest — June is a race against rising temperatures. You're transitioning from spring crops to summer survivors. Soil temps are already in the 70s and 80s°F (21–27°C), which is perfect for heat-lovers but means cool-season crops are done.
Plant now:
- Southern peas (Vigna unguiculata) — black-eyed peas, cowpeas, crowder peas all thrive in summer heat
- Okra (Abelmoschus esculentus) — direct-sow now; it loves heat and produces prolifically once it gets going
- Lima beans (Phaseolus lunatus) — need warm soil to germinate and handle summer temps well
- Sweet potatoes, yard-long beans, and Malabar spinach (Basella alba) as a heat-tolerant greens substitute
- Last call for tomato and pepper transplants — get them in by mid-June or they won't establish before the worst heat
Zones 9–10: The Heat Strategy
Zones 9 and 10 — Southern California, the Gulf Coast, South Florida, the Desert Southwest — play a completely different game. Summer here isn't "growing season" for many crops; it's survival season. Your june planting guide looks nothing like a Zone 5 gardener's.
Plant now:
- Armenian cucumbers (Cucumis melo var. flexuosus) — they handle heat far better than standard cucumbers
- Monsoon crops in the Desert Southwest: tepary beans, Sonoran milkweed, devil's claw
- Sweet potatoes — they love 100°F+ days and keep producing through fall
- Heat-tolerant herbs: Thai basil, rosemary, oregano
- Start planning your fall garden — in many Zone 9–10 areas, you'll begin planting tomatoes and peppers again in August
If you followed our May planting guide, you're already ahead of the curve. June is about building on that momentum — filling in gaps, starting successions, and pivoting to heat-adapted varieties.
Summer Vegetables to Plant in June: The Big Producers
Let's dig into the specific vegetables that make June planting so rewarding. These are the crops that turn a garden from "nice hobby" into "we're drowning in produce by August."
Succession Planting: Beans and Cucumbers
If you only do one thing this June, make it succession planting. The concept is simple: instead of planting 40 feet (12 m) of beans at once and getting a single overwhelming harvest, plant 10 feet (3 m) every two weeks. You get a steady supply from July through first frost.
Bush beans are the king of succession planting. Varieties like 'Provider', 'Contender', and 'Blue Lake 274' go from seed to harvest in about 50–55 days. Plant a row in early June, another mid-June, and a third in early July. By August you'll be picking beans every few days instead of frantically trying to process 20 pounds at once.
Cucumbers benefit from the same approach. A second sowing in June — especially a variety like 'Marketmore 76' or 'Diva' — ensures you have fresh cukes through September, long after your May planting succumbs to powdery mildew or cucumber beetles. For more on growing great cucumbers, check out our complete cucumber growing guide.
Transplanting Peppers and Eggplant
June is prime time for transplanting peppers and eggplant in most zones. Both are members of the Solanaceae family and demand warm soil — ideally 65–70°F (18–21°C) — to establish strong root systems. If you've been hardening off pepper starts on your porch, now is the moment to commit them to the garden.
Peppers: Space sweet peppers 18 inches (45 cm) apart, hot peppers 12–15 inches (30–38 cm). Dig in a handful of compost and a tablespoon of bone meal per hole. Don't rush — planting peppers into soil below 60°F (15°C) stunts them for weeks. 'Carmen' (sweet), 'Shishito' (mild), and 'Thai Dragon' (hot) are all reliable June transplants.
Eggplant: Give these more space — 24 inches (60 cm) between plants. They're heavy feeders, so amend with compost and a balanced organic fertilizer. 'Black Beauty' is the classic, but 'Ichiban' (Japanese) produces earlier and handles heat well. Stake them early; eggplants get top-heavy fast.
Other Summer Vegetables Worth Planting
- Summer squash and zucchini — Direct-sow in hills, 3 seeds per hill, thin to the strongest. You'll be giving away zucchini by late July.
- Edamame (Glycine max) — Direct-sow in early June. 'Midori Giant' matures in about 75 days and handles a range of zones.
- Melons — Cantaloupe and watermelon transplants go in now. They need warm soil, full sun, and consistent moisture. Drip irrigation is your friend here.
What Flowers to Plant in June
June isn't just about vegetables. Some of the showiest summer flowers go in the ground right now, and they'll reward you with blooms from midsummer straight through October.
Zinnias: The Easiest Win
Zinnias (Zinnia elegans) are the ultimate june planting flower. Direct-sow seeds after your last frost — they germinate in 5–7 days in warm soil and start blooming in about 60 days. No transplanting needed, no fussing. Just scatter, thin to 6–12 inches (15–30 cm) apart, and wait.
The variety range is staggering. 'Benary's Giant' produces dinner-plate blooms perfect for cutting. 'Queen Lime Orange' is a florist favorite. 'Profusion' series are compact and disease-resistant. Plant a mix and you'll have bouquets on every table from August through frost. Cut-and-come-again — the more you harvest, the more they produce.
Sunflowers: Still Time to Start
Sunflowers (Helianthus annuus) are another direct-sow June winner. Most varieties go from seed to bloom in 60–90 days, so a June planting means late summer and early fall flowers. Plant seeds 1 inch (2.5 cm) deep, 6 inches (15 cm) apart, and thin to 12–24 inches (30–60 cm) depending on the variety.
'Autumn Beauty' gives you a mix of warm reds, oranges, and yellows on branching stems. 'Mammoth Grey Stripe' is the classic towering single-head sunflower. For pollinators, 'Lemon Queen' is unmatched — it produces a continuous succession of pollen-rich blooms that bees absolutely mob.
Dahlias: The Late-Summer Show
If you haven't planted dahlia (Dahlia spp.) tubers yet, early June is your last good window in most zones. Dahlias need 90–120 frost-free days to bloom, so the math is tight if you're in Zone 5 or below. In Zones 7–9, June planting is perfectly timed for spectacular September and October blooms.
Plant tubers 4–6 inches (10–15 cm) deep with the eye facing up. Don't water until you see growth — overwatering before sprouting is the number-one killer of dahlia tubers. Once they're up, pinch the center shoot when they reach 12 inches (30 cm) to encourage branching and more blooms. 'Café au Lait' (cream-blush), 'Thomas Edison' (deep purple), and 'Bishop of Llandaff' (scarlet with dark foliage) are all stunning choices.
What Herbs to Plant in June
June is prime time for heat-loving herbs that refuse to cooperate in cool spring soil. These aren't the parsley-and-chives crowd — these are the Mediterranean and tropical herbs that finally come alive when temperatures climb.
Basil
Basil (Ocimum basilicum) is the poster child for June planting. It needs soil temps above 60°F (15°C) to even germinate and grows fastest when nights stay above 50°F (10°C). Direct-sow or transplant now and succession-sow every 3 weeks for continuous harvest. 'Genovese' for pesto, 'Thai Sweet' for stir-fries, 'Purple Ruffles' for visual drama. Pinch flower buds aggressively to keep leaves coming.
Other Must-Plant June Herbs
- Cilantro (Coriandrum sativum) — It bolts fast in heat, so sow every 2 weeks and plant in afternoon shade. 'Calypso' is the slowest-to-bolt variety available.
- Dill (Anethum graveolens) — Direct-sow now for summer harvests. Let some go to seed for pickling and to attract beneficial insects.
- Rosemary (Salvia rosmarinus) — Transplant container starts into well-drained soil. Once established, it's drought-tolerant and nearly indestructible in Zones 7+.
- Lemongrass (Cymbopogon citratus) — A tropical perennial that thrives in summer heat. Buy a stalk from the grocery store, root it in water, and plant out. It grows into a gorgeous 3-foot (1 m) ornamental grass.
What NOT to Plant in June
Knowing what to plant in june is only half the battle. Knowing what to skip saves you time, money, and the heartbreak of watching crops fail.
- Peas (Pisum sativum) — Cool-season crop. If your soil is above 70°F (21°C), pea seeds will rot or produce sickly plants that yield almost nothing. Wait until late summer for a fall crop in Zones 5–7.
- Lettuce and spinach — Bolt immediately in June heat for most zones. The exception: Zones 3–4 can still get a quick crop in early June. Everywhere else, switch to heat-tolerant greens like Malabar spinach, amaranth, or New Zealand spinach (Tetragonia tetragonioides).
- Broccoli and cauliflower transplants — Don't transplant them into a hot June garden. Start seeds indoors now for transplanting in July or August (fall harvest).
- Garlic — Garlic planted now won't have time to form bulbs. It needs fall planting and overwintering. If you missed it, buy from the farmers market this year and plant in October.
- Bare-root perennials — The shipping and planting window closed in April. Container-grown perennials are fine, but bare-root stock will struggle to establish in summer heat.
Tips for Hot-Weather Planting in June
Planting in June isn't the same as planting in April. Higher temperatures, stronger sun, and faster evaporation mean you need to adjust your approach. Here's what works:
Water Smart
Water deeply in the morning — early, before 9 AM. This gives plants time to absorb moisture before afternoon heat drives evaporation. Deep watering (soaking the top 6–8 inches / 15–20 cm of soil) encourages roots to grow down instead of staying shallow and vulnerable. Drip irrigation on a timer is the gold standard. For a deeper dive on watering technique, see our complete watering guide.
Mulch Everything
A 3–4 inch (7–10 cm) layer of organic mulch — straw, shredded leaves, wood chips — is the single most impactful thing you can do for a June garden. Mulch keeps soil temperature 10–15°F (5–8°C) cooler than bare soil, retains moisture, suppresses weeds, and feeds soil biology as it decomposes. Don't skip this step. It's not optional in summer.
Plant in the Evening
Transplant in the late afternoon or evening — never in the heat of midday. Seedlings transplanted at 6 PM get a full cool night to recover from transplant shock before facing the next day's sun. This alone can be the difference between a transplant that takes off and one that wilts and dies within 48 hours.
Use Shade Cloth for New Transplants
A 30–50% shade cloth draped over newly transplanted seedlings for the first week reduces transplant shock dramatically. You can DIY this with old sheer curtains or lightweight row cover. Remove it once plants show new growth — they'll be established enough to handle full sun.
Amend and Feed
June-planted crops are going into soil that's been growing things for a couple months already. Before planting a new succession or filling a gap, work in an inch (2.5 cm) of compost and scratch in a balanced granular organic fertilizer. Think of it as refueling the soil for the next round of production.
Sam's June in San Diego: Real Talk
Sam from San Diego learned the hard way that June planting in Zone 10a is its own game. "I moved from Ohio three years ago and kept trying to plant like a Midwest gardener," he says. "Peas in June? Dead in a week. Lettuce? Bolted before I picked a single leaf." His turning point came when he stopped fighting the climate and leaned into what actually thrives: Armenian cucumbers, yard-long beans, and Malabar spinach replaced his cool-season staples. He built a dedicated shade structure for his herbs and switched to 100% drip irrigation.
The biggest game-changer? Connecting with other local growers through Tendra's Twin Plant Mates feature. "I matched with a neighbor two blocks away who'd been growing 'Dragon Roll' cucumbers and 'Thai Purple' eggplant for years in the same microclimate," Sam explains. "She taught me about thermal mass watering — soaking the raised bed walls at night so they release moisture slowly during the day. My transplant survival rate went from maybe 50% to over 90%."
Sam's setup now includes succession plantings of beans every three weeks, a dahlia patch that blooms from August through December in his mild climate, and a herb garden that's essentially a year-round operation. His advice for fellow warm-zone gardeners: "Stop looking at national planting charts and start talking to the people actually growing food on your street."
Make June Count
June is one of those months where the garden either gains momentum or stalls out. The gardeners who keep planting — succession sowing beans, tucking in one more round of cucumbers, getting those dahlia tubers in the ground — are the ones harvesting armloads of produce and bouquets in August and September. The ones who stop planting after May miss half the season's potential.
Know your zone. Plant what works for your climate right now. Mulch like your garden depends on it (it does). And don't plant peas in June — just don't.
