Also question is, does clematis bloom all summer?

Keeping this in consideration, why is my clematis not blooming?

Fertilizer – Improper fertilization is often the reason for a non-blooming clematis. Usually, the problem isn't lack of fertilizer, but too much, which may produce lush foliage and few blooms. Age – Be patient if your clematis is new; give the plant some time to establish and develop healthy roots.

Do clematis come back every year?
