my Rhus is over 30years old, and approx 15ft high, the main trunk has a split of about 14ins with a thick resinous goo exuding from it. There a sucker growing next to the trunk which i have kept as a replacement. The problem is it next to a garden wall, in a very small area, and is always putting out suckers. The foliage seems to get thiner each year, and the flower small and pale. The birds love this tree as the branches are wide. Being next to the road i am fearful that it will topple, and land on my car. Help what can i do.
