Answer: Sparse root mass might indicate over-watering, or soil that drains too slowly for your Arbutus. It likes regular water, but the roots will suffocate if the soil remains soggy for any length of time. Thin, leggy growth might also indicate stress from root problems. If your lawn is watered by automatic sprinklers, try shutting off the sprinklers that soak the soil directly beneath the tree. If you hand water, avoid watering beneath the tree. This will encourage deep root growth, which will also improve the tree's ability to anchor itself in the soil. Best wishes with your Arbutus!
