How much sun are they getting? Many kinds need at least a few hours of direct sun a day to form buds.

if you only moved them last year they may flower well this year. Most are happy in shade.

I apologize. I had better stick to plants that I have grown personally. And have a talk with my Aunt!

I have been juggling my geraniums about a bit recently. I put several small bits(no longer blooming) in a battered old pot as a temporary refuge. They have galloped away after starting off on shade. Now in what will be dappled shade. They thrive well in between taller plants. Some varieties can be a bit feisty if not checked. They can be like a trailing plant, in the shade, if the pot is raised up. I have one pink one.....none invasive and one purple which goes where it wants....then gets pulled out in autumn!!!!!. It has dropped seeds and is a chancer. Always blooms....but it has chosen where it blooms.
