Can You Still Plant Vegetables in June? (Yes — Here’s What to Try)

Yes, you can still plant vegetables in June in the Cleveland area. While it’s too late for early spring crops, June is perfect for heat-loving veggies like beans, squash, cucumbers, and even a second round of greens. With warm soil and longer daylight, it’s prime time for fast-growing, summer-harvest varieties.


Introduction

Thought you missed your chance to plant a garden? Think again. June might be late for peas and broccoli, but in Cleveland’s growing zone (6a–6b), it’s the perfect time to direct-seed summer vegetables and even sneak in a few quick greens.

Whether you’re filling in empty spots, starting a new bed, or reviving a failed spring crop, this guide will show you:

  • What vegetables grow well when planted in June

  • How to time harvests before fall frost

  • Tips for Cleveland’s unique summer climate

  • Mistakes to avoid for late-start gardens


Cleveland Climate: What You’re Working With

Cleveland sits in USDA Zone 6a/6b with:

  • Last frost date: ~May 10

  • First frost date: ~October 15

  • Growing season length: ~155–165 days

That means June plantings still have 100+ frost-free days, which is more than enough time for most summer crops — especially if you choose fast-maturing varieties.


Top Vegetables to Plant in June (Cleveland-Approved)

🌱 1. Bush Beans

  • Why it works: Warm soil speeds up germination; beans grow fast.

  • Time to harvest: 50–60 days

  • Pro tip: Try ‘Provider’ or ‘Contender’ varieties for reliability in local soils.


🥒 2. Cucumbers

  • Why it works: These heat lovers thrive in June warmth.

  • Time to harvest: 50–70 days

  • Pro tip: Direct-seed near a trellis to save space and reduce disease.


🎃 3. Zucchini & Summer Squash

  • Why it works: Quick-growing, high-yielding — and June is their moment.

  • Time to harvest: 45–60 days

  • Pro tip: Watch for squash vine borers around late June; row covers help.


🌽 4. Corn

  • Why it works: It loves warm soil and long summer days.

  • Time to harvest: 70–90 days

  • Pro tip: Plant in blocks (not rows) for better pollination and fuller ears.


🥬 5. Leafy Greens (Heat-Tolerant Types)

  • Why it works: Varieties like Swiss chard, collards, and ‘Red Russian’ kale can handle summer better than lettuce.

  • Time to harvest: 30–60 days

  • Pro tip: Grow in partial shade or under row cover to reduce heat stress.


🌶 6. Peppers (Transplants Only)

  • Why it works: June soil is warm enough to support fast transplant growth.

  • Time to harvest: 60–90 days

  • Pro tip: Use black landscape fabric or mulch to retain heat and speed up ripening.


🍅 7. Tomatoes (Transplants Only)

  • Why it works: Still enough time to ripen, especially if you pick early or determinate types.

  • Time to harvest: 60–75 days from transplant

  • Pro tip: Choose fast-maturing varieties like ‘Early Girl’ or ‘Celebrity’ for reliable Cleveland harvests.


🥕 8. Root Crops (Late June/Early July)

  • Why it works: Carrots and beets can be seeded now for a fall harvest.

  • Time to harvest: 60–75 days

  • Pro tip: Keep soil consistently moist until germination — especially during Cleveland’s dry July spells.


Bonus: Succession Planting Ideas

If you planted spinach, arugula, or radishes in April and they’ve already bolted or been harvested, June is your chance to replant. Use that space for:

  • Bush beans

  • Mini cucumbers

  • Summer lettuce mixes

  • Compact zucchini or pattypan squash

This keeps your garden productive without starting from scratch.


Cleveland Tips for June Gardening Success

✅ Watch for dry spells

June in Cleveland often starts wet, but by late June, soil can dry out fast. Mulch and consistent watering are key.

✅ Don’t forget pest control

Japanese beetles and cucumber beetles show up by late June — check plants daily.

✅ Use row covers or shade cloth

Especially helpful for leafy greens and young transplants during heat waves.

✅ Harden off late-start transplants

Even in June, transplants from a nursery or indoor grow tent need 3–5 days of gradual outdoor exposure.


FAQ: June Vegetable Planting in Cleveland

Is it too late to plant tomatoes in June?
No — as long as you’re using healthy transplants. Look for fast-maturing varieties to ensure harvest before fall frost.

Can I still grow lettuce or spinach in June?
Only with shade and heat-tolerant varieties. Traditional spring lettuces will bolt in full sun.

Should I fertilize June plantings?
Yes — especially for heavy feeders like squash, corn, and tomatoes. Mix compost into soil or use a balanced organic fertilizer.

How often should I water new seeds in June?
Daily at first — soil dries quickly in sun-warmed beds. Once seedlings emerge, switch to deeper, less frequent watering.

Can I grow fall crops if I plant now?
Absolutely. June plantings of carrots, beets, kale, and collards can mature nicely into fall with the right timing.
