blind primroses

Question

I bought 80 primroses in plug form and when they matured, at least 50% were blind and had no flowers. The ones that flowered were perfect. Tey were brought up in a cold greenhouse.

Answer 1

We have a number of articles on the cultivation and care of primroses:

If you are not satisfied with the performance of the plants you ordered, you should certainly take it up with the grower and/or supplier.
