My 3-yr old clematis vine was full of beautiful large blooms (blue 6-7 petals) early to mid spring, then died back. Now it has new growth and blooms. I remember something similar last year. Any ideas?
Clematis fall into 3 groups, mainly for pruning. If it flowers before June as yours has, you should (have) pruned it after flowering. Enjoy the second flowering but to maintain the shape you should trim back after next year's flowering.
