by

Planting groundcovers under trees can enhance the beauty of your landscape, suppress weeds, and protect the soil. For gardeners in Zone 3, choosing the right groundcover is essential due to the cold winters and short growing seasons. Here are some top picks that thrive under trees in Zone 3.

Factors to Consider When Choosing Groundcovers for Zone 3

Before selecting a groundcover, consider factors such as:

  • Cold hardiness: Must withstand harsh winters.
  • Shade tolerance: Adaptability to low-light conditions under trees.
  • Root competition: Ability to coexist with tree roots without causing damage.
  • Maintenance needs: Low-maintenance options are preferable.

Top Groundcover Picks for Zone 3

1. Creeping Phlox (Phlox stolonifera)

This hardy perennial forms a dense mat of vibrant flowers in spring. It tolerates shade and cold temperatures well, making it ideal for planting under trees in Zone 3.

2. Sweet Woodruff (Galium odoratum)

With fragrant white flowers in late spring, sweet woodruff thrives in shaded areas and is very cold-hardy. It spreads easily and requires minimal maintenance.

3. Bearberry (Arctostaphylos uva-ursi)

This evergreen groundcover offers year-round interest. It tolerates shade and cold climates, and its low-growing habit makes it suitable for planting beneath trees.

4. Hosta (Hosta spp.)

While not a traditional groundcover, low-growing hostas can fill in shaded areas under trees. They are hardy in Zone 3 and provide lush foliage throughout the growing season.

Planting Tips for Success

To ensure your groundcover thrives under trees, follow these tips:

  • Prepare the soil: Improve soil drainage and fertility if necessary.
  • Avoid planting too close to the trunk: Leave space for root expansion.
  • Water adequately: Newly planted groundcovers need consistent moisture.
  • Mulch lightly: Use organic mulch to retain moisture and suppress weeds.

Choosing the right groundcover can transform shaded areas under trees into lush, low-maintenance parts of your landscape. With careful selection and planting, you can enjoy a beautiful garden year-round in Zone 3.
