Pacysandra choking rhododendron roots?

Asked August 18, 2019, 8:51 AM EDT

Does pacysandra choke out the roots of other plants? I have a planting with azalea's, rhododendrans, and boxwoods. Pacysandra has spread underneath and around the shrubs. One rhododendran is now dying. I wondered if it were dying due to thirst or perhaps the pacysandra wrapping around the plants.

Pachysandra is very thick and highly competative for water and nutrients. Established shrubs can usually compete with it, but rhododendrons and azaleas are shallow-rooted and certainly may need extra watering during dry spells as they get established.

Pachysandra is a non-native plant that is considered invasive and should not be allowed to spread near woods, parks or natural areas as it takes over and out-competes the native plants that our wildlife evolved to need.
