passion flower not blooming

Question

Have a very green healthy looking passion flower on a fence which gets sun and shade. Had 3 beautiful flowers on which opened about 2 weeks ago. Now have about 6 more buds which fail to open and are just dry inside. Have watered regularly. What am I doing wrong, please?

Answer 1

Make sure the water is draining properly.
A midsummer fertilizer is a good idea, look for a balanced fertilizer.
Bone Meal also can promote flowering.
