Crinkly leaves on Gerbera Daisies
I over-wintered a beautiful yellow Gerbera Daisy, then purchased a new red one this year. I planted them together in a 12 inch pot. Both are growing well, the red one is blooming, however the yellow one has excellent growth but very crinkly dark green leaves. No yellow blossoms yet. What causes the crinkly leaves and how can I cure it? Thanks for your response.
This is, usually, caused by a pH issue. It is best to have a soil tester to be able to test the pH in order to know how much acid or alkaline product to add. You will want to go for a target pH of 5.5 to 6.5 for the best results.
