do you fertilize clematis
Fertilize your established clematis once per month throughout the growing season, starting in early to mid-spring and continuing into midsummer. Use a balanced 10-10-10 fertilizer at a rate of approximately 4 tablespoons per 10 square feet of garden around the vine. Discontinue fertilization if blooms appear, because applications of fertilizer during bloom can shorten the length of bloom time for the clematis.
