Care Guide

Planting

Plant your Coyote Willow in full sun in a location where it can access consistent moisture - ideally near a water feature, low-lying area, or spot where you can maintain regular irrigation. This willow tolerates poor drainage and various soil types as long as moisture is abundant, so don't worry about amending heavy clay. Space it with other wetland plants and shrubs, and note that it will eventually spread via underground shoots to fill any wet soil it can reach, so plan accordingly for its mature size of 10 to 23 feet.

After Planting

Water consistently to keep the soil moist through your first summer and beyond - this is not a drought-tolerant plant and drying out is your biggest risk. Once established, maintain that moisture-rich environment year-round; you're not really weaning it off water the way you would other plants. The plant is deciduous, so expect it to drop its leaves in winter and regrow them in spring. Prune after flowering or during dormancy to manage its spreading growth habit, but the Calscape data doesn't specify detailed pruning methods, so consult a local nursery for technique specifics.
