Weeds in potting compost
I've had far more weeds in my pots this year than ever before. In the past I've never had more than the odd little weed seedling to remove which has most likely been blown in. Today I've just removed a number of really well established weeds which I strongly suspect developed from weed seeds in the compost. I hadn't noticed them before because the pots are closely planted and the weeds have just started to stick their heads above the other plants. The large weeds are only in pots with new compost.
Anybody else had similar problems. I've used the same make of potting compost for a number of years but the stuff this year has been very poor by comparison to previous years.
