How do I winterize my outdoor plants?

When should I winterize my outdoor plants?

Late fall is the best time to winterize perennial plants. A hard frost can be the signal to prep the beds for winter. If below-freezing temperatures are forecasted overnight, or you wake up to frost on the ground, it's likely a good idea to winterize your perennials within the next few weeks.

How do you winterize plants for the winter?

Build a small screen around plants, heap soil over roots and stuff the screened-in area with leaves or straw. For some tender perennials, cut back top growth and place a layer of packing foam over the plant crown, topped with several inches of soil. Once that freezes, add a mulch layer for extra protection.

How do you winterize outdoor potted plants?

Wrap pots in burlap, bubble wrap, old blankets or geotextile blankets. It isn't necessary to wrap the entire plant because it's the roots that need shielding. These protective coverings will help to trap heat and keep it at the root zone.

Should you cover outdoor plants in winter?

If you're leaving them outside, push them together and cover them. Wrap the containers in plastic or burlap to help them stay warmer. A layer of mulch can help protect perennials and newly planted shrubs and trees when cold temperatures hit.

Can I leave perennials in pots over winter?

You can overwinter them by moving the pots into a cold frame or unheated garage for the winter after the first hard frost. Since all perennials require a period of dormancy or a cold treatment to bloom, don't overwinter them in a greenhouse or other warm place where they will not go dormant.

Can I cover plants with garbage bags?

Yes – if you secure the plant properly. Garbage bags work to cover plants and protect from frost, but they must not be allowed to touch the plant's surface. Use stakes and supports to create a tent-like structure over the plant, which will retain warm air. Make sure the trash bag goes all the way to the ground.

Should you cut back perennials in the fall or spring?

Some perennials, like hostas, peonies and daylilies, need to be pruned in fall to avoid winter damage. Plants like these should be pruned after the first few frosts in late fall or early winter. Other perennials like mums and coneflowers are better off being pruned in spring just before new growth comes in.

Can you keep soil in pots over winter?

Any storage containers that will keep the soil dry will work, including bins, small garbage cans, or heavy-duty plastic bags. Exposure to freezing temperatures is good for stored potting soil, because it will make life difficult or impossible for any insects that may be present as adults, pupae or eggs.

How do you protect perennials in the winter?

The best time to mulch perennials is after the top 1-2 inches of soil has frozen. The mulch provides insulation, keeping the soil consistently cool through winter.
