Plants not growing under Cedar tree
Why doesn't anything but weeds grow under my cedar tree?
Submitted by trollkarl9141

Hi, Cedar trees, and other conifers, are almost impossible to grow plants under because of the root and light competition (and sometimes the soil pH is more acidic under mature conifers). We generally recommend mulching underneath conifers instead of trying to grow things underneath them. Some weeds seem to do fine in those conditions, but most plants we like don't do well. Or, you can trim up the tree and place containers filled with shade-loving flowers there to perk things up, but don't bother trying to grow anything nice in the soil underneath.
