My crocus sativus does not flower

Question

I planted about 20 crocus sativus bulbs two years back in two big pots. Last year I got lot of spiky leaves but no flowers. I kept them dry throughout summer and then this year I got spiky leaves also, but only two flowers. Can you please tell me what I am missing? Thanks for your help.

Answer 1

I would try giving the plants some phosphorous. Bone meal is a good source of this. Phosphorous is needed in order for plants to bloom and being in pots, they may be lacking this.
