Can hosta's be cut back in the fall?
Yes, when the foliage has yellowed, you may cut it down to the ground. If it is a type that has thin leaves, it may compost in place. Hostas with thicker leaves like the blue-tinged varieties are best placed in the compost pile after chopping them up a bit. If you have a new garden, you may want to mark where the hosta are located so you don't accidentally dig into one. Hosta never need dividing but spring, just as they start to emerge, is a good time to divide them if you want to increase the number of plants.
