Q.My Phlomis Hasnot Flowered
We planted 3 Phlomis pants purchased from Crocus last year and while we have lots and lots of leaves no flowers have appeared, we added sulphate of potash around the roots last month but no noticeable difference still just leaves. the ground is mainly spent compost , leave mould and soil. when is the best time to transplant these plants to a more free draining /grit soil?

I think the simplest answer is that your soil probably contains too much nitrogen. You may want to do a soil test to be sure. Excess nitrogen generates lots of leaves, but doesn't allow for flowering.

Since the plants are otherwise healthy, it doesn't sound like a drainage problem. If you can wait until spring to transplant them, they might respond better, but wait until there's no more chance of frost.
