Globe Maples are stunning, but let’s be real—those shallow roots can be a bit of an eyesore when they start poking out of the ground. If you’re looking to tidy up the base of your tree and add some visual interest, planting groundcovers is the way to go.
What are the best plants to grow under a Globe Maple?
Because of the dense root system, most typical garden flowers and perennials just don’t have the space to thrive under a Globe Maple. However, there are a few tough contenders that don’t mind partial shade or “root competition.” These groundcovers are perfect for the job:
- Barrenwort (Epimedium)
- Periwinkle (Vinca)
- Waldsteinia (Barren Strawberry)
The blooms on these plants look fantastic against the tree’s vibrant foliage, which puts on a show well beyond just the autumn months. If you’re looking to plant something directly against the trunk, you’ll need a hardy variety that can handle full shade. My top picks for those spots are:
- Foamflower (Tiarella)
- Ivy
- Wood Rush
How to properly plant under your Globe Maple
The sweet spot for underplanting your maple is between July and September. By this time, the tree has finished most of its seasonal growth, so your new plants won’t have to fight as hard for water and nutrients. That said, you can technically do this anytime during the growing season. Here’s how to get it done:
- Soak the root balls of your new plants in a bucket of water before you start.
- Clear away any weeds or grass from the area directly under the tree’s canopy.
- Use a hand trowel to gently feel around for open pockets between the tree roots.
- Mark these spots with small wooden stakes or sticks so you know where to dig.
- Spread a 1.5 to 2-inch layer of fresh potting soil or garden compost over the entire area.
- Dig your planting holes at the marked spots.
- Let the new plants drip dry for a second, then tuck them into their new homes.
- Firm the soil down with your hands and give everything a generous watering.
