What to plant this week in Cleveland, OH
In Cleveland, the calendar officially flips to late spring as our average last frost date of April 3rd passes, signaling that hardy summer crops like basil and beans are finally ready for your beds. With overnight lows hovering near freezing only in early April, the immediate priority is maximizing this narrow window before the soil warms up enough for rapid germination.

- Cleveland's heavy clay-loam soils retain moisture well but work slowly; avoid tilling wet ground to prevent compaction as you plant these warm-season crops now.
- The urban heat island effect in neighborhoods like Tremont and Little Italy allows you to start outdoor tomatoes and peppers a week earlier than the county average suggests.
- Plan your garlic harvest for early November, aiming to pull bulbs by Nov 6 before our first frost forces premature growth cessation.
- Monitor soil temperature closely; while we can sow transplants now, waiting until mid-April ensures root establishment in our often-cold Ohio spring.

Seasonal tips
- Succession sow bush beans or carrots every two weeks to extend your summer harvest window.
- Pinch back the tips of basil and Italian herbs like summer savory to encourage bushier growth before frost.
- Start planning your fall crop rotation; avoid planting nightshades in beds that held them last year.
- Apply a light layer of compost around perennials now to strengthen roots for winter dormancy.
Pest & disease watch
- As temperatures rise above 50°F, watch for early aphid colonies forming on the undersides of newly emerged bean leaves.
- Spider mites may appear if any late-winter indoor starts are moved outside too soon and exposed to dry, windy conditions typical of our lake breezes.
- Fungal issues like powdery mildew can start developing on cucurbits (cucumbers, squash) as humidity increases in the afternoon.
Watering this week
Water deeply in the morning to keep roots hydrated during heat waves while reducing fungal risks on leafy greens.
Harvest watermelons when they make a hollow sound upon tapping, ensuring you get the sweetest fruit before the first frost hits.
