I have a blue hydrangea in an indoor pot that flowered once already. I pruned it and it started to have new growth, however, the leaves have what looks like an odd mold in round patches, and the soil seems to always get mold on the top of it. Also, now the leaves are getting wilty on the edges.
I put it in water every week for about a day (soaking from the bottom) and it is in an Eastern exposure, so it gets sun for a good part of the day.
I recently re-potted to a larger container, but I still have this problem.
Is it too much water?
Thanks for any help you can offer!
