More peonies, please – Peonies never have to be disturbed if they’re blooming happily, but if you want to make more plants by dividing a plant, you can do so in the fall, Ward Upham of Kansas State says. Be aware, though, that it can take three years for the plants to reach full size and bloom. Be sure that the places where you plant the divisions get at least a half day of full sun.

Here are Upham’s instructions for dividing:

First, remove the leaves, then dig up the entire plant. Shake and wash off as much soil as possible so that the pink buds or “eyes” are visible. Each division should have three to four buds, and you’ll need to use a sharp knife to cut through the tough roots.

Space the plants so that there is at least 2 feet between dwarf types and 4 feet between standard types.

Planting for divisions is the same as for new plants: Make sure the pink buds are about 1 inch below the soil, and no more. As you place soil around the plants, keep firming the soil as you go so that the eye does not sink any lower than 1 inch. Water in well, and continue to water through fall and winter as needed to keep the soil moist.

After the soil freezes – usually sometime in December – add a mulch of straw, leaves, compost or other organic material.

Plant – Lettuce, radishes, spinach and turnips.

Asparagus and rhubarb – Asparagus and rhubarb plants are now building up reserves that they’ll need next year, Upham says. Water the plants when the weather is dry and remove the weeds, he says, and be sure to leave the plants’ foliage until all the green is gone. It can then be left for the winter to help collect snow or can be removed, he says.
