Frequently Asked Questions
Q1 What are the best plants for Ohio gardens?
The Ohio buckeye is the iconic native choice. Purple coneflower, black-eyed Susan, spicebush, and wild geranium all thrive in Ohio's clay soils and climate. Hostas and daylilies are reliable performers for shady and sunny spots respectively.
Q2 When should I plant in Ohio?
Spring planting (late April to May) is best for most perennials and annuals after the last frost around mid-May in central Ohio. Fall (September to mid-October) is excellent for trees, shrubs, and bulbs. The growing season runs roughly 150-180 days.
Q3 How do I garden in Ohio clay soil?
Don't fight the clay — work with it. Amend the top layer with 2-3 inches of compost each year. Choose clay-tolerant plants like switchgrass, aster, and Joe Pye weed. Avoid rototilling wet clay as it creates brick-like clods. Raised beds work well for vegetables.
