Tree Root Care

Most of a trees critical roots are the very fine, fibrous roots lying especially close to the surface and if these roots are buried by more than a few inches, the tree could die due to a lack of oxygen.

But there are ways to successfully plant ground cover plants under the tree just make sure not to add more than a couple of inches of soil and compost around the base of the tree.

Be careful about putting a large amount of soil over tree roots. Tree roots need oxygen, and dumping a thick layer of dirt on them can suffocate them.

How do you prepare a ground cover around a tree? Good question … and I’ve got the answers below.

Ground cover will thrive when you follow these tips.

Preparing the Site

Ground cover can be planted any time of the year but early spring or late spring, and fall are always the best times to plant.

1) You want to make the bed the same size as the tree canopy. I eyeballed it but you can lay a hose or spray paint the area to figure out the right size before you start.

2) Use a flat head shovel (I like one like this with a handle) to create a border all the way around the tree. Digging is much easier if the ground is soft so try to do this after a rainstorm or a good soaking with a hose.

3. I used the same flat head shovel to lift away the top layer of grass. My husband preferred doing this part with a spear head spade. Pluck out any patches of grass around tree roots by hand.

Tip: Removing grass by hand is the best way since chemicals can harm the tree.

4. Add topsoil if your bed needs it but be careful about putting a large amount of soil over tree roots since they need oxygen to breathe.

5. With plants in their pots, lay them out in the bed so you can space them evenly. Don’t plant anything too close to the large roots closest to the tree.

Choose the location of plants carefully to avoid the need to chop out larger tree roots but you can cut through a few of the smaller, fibrous roots without damaging the tree.

Tip: Choose plants with shallow roots if you have lots of exposed tree roots.

6. Using a small, sharp hand shovel or a bulb planter (what I used), dig holes deep enough to fit the ground cover and plant each so that the top of the soil in the pot is even with the top layer of earth.

Tip: Watering the potted ground cover before planting makes the job easier.

The ground cover will spread quickly and cover the entire bed! I’ll just have to trim it occasionally it to keep it from spreading out of the bed and into the grass.

Vinca Minor Ground Cover

I planted 51 vinca minor that came in 3 1/2″ pots (almost three full flats) around my tree. Also known as creeping myrtle, common periwinkle, dwarf periwinkle, this is a tough, low-maintenance semi-evergreen, flowering ground cover that is pest resistant and simple to grow. The bonus is that butterflies and hummingbirds love the cone shaped blooms!

These hardy perennials ground cover spreads quickly and will soon cover the mulch and be a spectacular bed of green foliage. It is considered invasive so it needs to be cut back if it starts growing outside of the bed.

Vinca minor grows well in zones 7, 8 and 9 so be sure to check out the USDA Plant Hardiness Zone Map to see if vinca will grow in your area. If not, there are lots of other ground covers to choose one so pick one best suited for your area and sun exposure.

I love that this perennial can be planted in full sun to full shade making it a great option for many landscapes and once established, they are drought-tolerant.
