Tips for Gardening in Clay Soil
Add Organic Matter
Mix compost, shredded leaves, or well-rotted manure into the soil. This improves drainage and helps roots grow.
Mulch Your Plants
Mulch keeps moisture in and prevents the soil from turning hard. Use straw, bark, or leaf mulch.
Avoid Overwatering
Clay holds water, so water less often—but deeply.
Don’t Dig When Wet
Clay is sticky when wet and crumbly when dry. Wait until it’s just moist before digging.
