What to plant this week in Toledo, OH
With the average last frost date for Toledo set at April 21, most hard frosts have passed, but watch for occasional cold snaps that can dip toward -5°F. This week marks the perfect time to plant out warm-season giants like pumpkins and summer squash before the October 24 first frost ends their season.
The next 7 days
Toledo, OHGrowing in Toledo right now
- Toledo's heavy clay soils near the Maumee River bank slowly; add organic matter or use raised beds for root crops and melons.
- The city sits in a microclimate prone to late spring frosts until mid-June, so keep sensitive transplants like zinnias under cover if a cold front approaches.
- Summer thunderstorms are common and can wash away topsoil on sloped yards; mulch heavily around newly planted watermelons and cucumbers.
- Wind from Lake Erie can be brisk in unsheltered areas of the city, so stake tall sunflowers and pole beans early to prevent snapping.

Seasonal tips
- Succession sow bush beans and cucumbers every two weeks for continuous harvests through August.
- Mulch heavily around young transplants and newly planted garlic to retain moisture as daytime temperatures rise.
- Pinch back the tips of bush beans and zucchini plants once they reach 6 inches to encourage branching and heavier fruit production.
Pest & disease watch
- Spider mites may appear on basil and zinnias if this week's dry spells persist despite recent rains.
- Cucumber beetles are actively seeking out young cucumber, squash, and melon vines for their first feeding wave.
- Aphids often cluster on new growth of okra and sweet corn during warm, humid Toledo afternoons.
Watering this week
Water deeply at the base of plants early in the morning to reduce evaporation and prevent fungal diseases.
Harvest zucchini and summer squash frequently when they are small (6 inches) to signal the plant to keep producing fruit.
Toledo gardening questions
3When should I plant my watermelon and cantaloupe seeds in Toledo?
You can sow these now outdoors or transplant them immediately since the danger of a hard frost has passed. Ensure you choose varieties that mature before mid-October to avoid losing fruit before the first freeze on October 24.
Is it safe to put out my garlic bulbs this week?
Yes, planting garlic now is ideal for Toledo's zone 6b climate as winter dormancy needs are met by early fall. Choose a sunny spot with well-drained soil and water in lightly before the ground freezes solid.
How do I protect my basil from the occasional late cold snap?
Cover young basil plants with row covers or old blankets when night temperatures threaten to drop near zero degrees. Remove covers during the day to prevent overheating and ensure they get enough light for bushy growth.
