When I bought my geraniums at the beginning of March they were healthy and produced lots of repeat flowers. I religiously dead-headed the plants on a regular basis and fed with MiracleGro to encourage growth.
and
by April the flower stalks had started to rot. I sprayed with a fungal spray but it did not seem to make a difference.
then i noticed the main fleshy stems were rotting from the inside. When I cut the geranium stem open it was rotten inside.
and
and
Within a couple of months I now have two sickly tubs of geraniums
After extensive research I now think they have stem rot. I am gutted. I thought geraniums were meant to be easy to grow. Has anyone else experienced this problem with geraniums?

There is a brownish coloured moth which you will see around the geraniums in june. It lays eggs and they hatch and burrow into the stem cutting of the transport system. You will see small holes all along the woody stems if u look closely. The only thing u can do is to try and protect them from the moth.
