I plan to try and persuade the new dahlia I planted to survive the winter with compost/leaf chippings over it. Do I cut it back first?
I have some small michaelmas daisies that I planted this year and they have been fine - bloomed well. I thought they might die back in the winter - but they look as if they have actually died! Is this how they look when they die back?
Yes, I would cut back the Dahlia, hope it survives. Michaelmas daisies will die right back and can be cut down to ground level. They will send up fresh leaves next year. Both these plants give late colour, I wouldn't be without them.
