5 Ways to Overwinter Potted Trees and Shrubs

Overwintering potted trees and shrubs can be a bit tricky, but it’s definitely doable. Here are five methods you can use to keep your plants healthy and thriving throughout the cold months.

  1. Bring Them Indoors

This is the most straightforward method, especially for smaller plants. If you have enough space indoors, bring your potted trees and shrubs inside to a cool location such as a walk-in basement. Avoid placing them near heat sources or cold drafts.

  1. Move Them to a Protected Area Outdoors

If you don’t have room indoors, you can move your plants to a sheltered spot outdoors. This could be a root cellar, greenhouse, garage, or even a shed. Make sure the area is protected from harsh winds and heavy snowfall and ensure that it is cool, dark, and has good ventilation.

  1. Insulate The Pots

Applying a thick layer of mulch around the base of your plants can help protect their roots from frost. Mulch also helps to retain moisture, which is important during the dry winter months. Consider wrapping the pots in burlap or bubble wrap. You can also put the pots in large cardboard boxes and stuff the open spaces and corners with fall leaves or straw.

Temporarily planting or burying the trees / shrubs while still in their pots for the winter is another great method. Just dig up the pots in the spring and plant them in their final location.

  1. Potting Up

If you’re worried about your plants not surviving the winter in their current pots, you can pot them up into larger containers. This will give their roots more room to grow and help them better withstand the cold.

Additional Tips:

  • Water Properly: During the winter, your plants won’t need as much water. However, it’s important to avoid letting the soil dry out completely.
  • Prune Carefully: If necessary, prune your plants before winter to remove dead or damaged branches. Avoid heavy pruning during the cold months.
  • Check Regularly: Periodically check your plants for signs of stress or damage. If you notice any problems, take steps to address them promptly.

By following these tips, you can help your potted trees and shrubs survive the winter and thrive in the spring.
