• Last frost date: ~May 10

• First frost date: ~October 15

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.
