Clematis may take 2-3 years to begin blooming. Here are a few care tips that may help your plant flower: most Clematis prefer their “feet” in the shade and their faces in the sun, so apply a layer of mulch around the plant leaving about 2-3 inches clear around the base of the plant. Water regularly when in the growth and bloom cycles and feed with a slow-release or organic fertilizer after blooms are spent. Be careful not to use a high nitrogen fertilizer as that will encourage leaf growth over flower formation.
