Groundcovers for Central Oregon

Look around Central Oregon and the groundcover of choice appears to be Kentucky Blue Grass which turns a lovely shade of green in the summer when we pour hundreds of gallons of water and fertilizer on it. Grass has its place in some landscapes, but we should be looking for other alternatives to use.

There are a variety of groundcovers that can be used to solve many landscape challenges such as steep banks or slopes, shady areas under trees and next to buildings; transitioning from driveways or sidewalks to shrub borders; areas where tree roots grow close to the surface; and very dry conditions.

Groundcovers under trees can be used to reduce the possibility of mower damage to the base of the tree. Some ground covers can protect the roots of shallow rooted trees by shading the soil and keeping it from drying out rapidly.

If you decide to use groundcovers in your landscape, make sure the area is clean. Remove all turf and plant only on a site that is free of weeds. Add compost to our sandy soil to provide nutrients and to help hold onto water. After planting, soak plants well and keep the soil moist until they are established. Apply 3” of mulch to help keep out weeds while the plants are filling in the space. Some hand pulling of weeds may need to be done in the first one or two growing seasons.

Cornell University conducted a five year study on groundcovers that are useful for suppressing weeds and there are some that thrive in Central Oregon. Groundcovers with a Good to Excellent Weed Suppressive Rating that grow in Central Oregon are:

  1. Its like you read my mind! You seem to know so much about this,
    like you wrote the book in it or something.
    I think that you can do with a few pics to drive the message home a bit, but other than
    that, this is great blog. A great read. I will certainly
