Hello- I want to plant some native groundcover in my backyard that’s quite shady and fairly dry. Something low maintenance. I am looking at Allegheny Spurge or a sedge. My question is, can I plant either of these now (end of August,) starting from small plants?
You can plant now if you can find the plants. You will have to keep watered up until the ground freezes so the root systems can get established. Mulch lightly and keep away from the base of the plants. Alleghany spurge is very slow to grow and does not like dry soils. Some suggestions include Pa sedge, sedum ternatum, pussy toes, and Christmas ferns.
