How to Remove Ball Moss From Trees. Ball moss, part of the bromeliad family, resemble small, pale green tumbleweeds attached to the branches of trees. It uses the tree branches for support and is not a parasite. Trees provide the perfect combination of shade, humidity and limited airflow allowing it to pull all the food and moisture it needs from the surrounding air. When ball moss becomes overwhelming however, it can be unsightly. Read on to learn how to remove ball moss from trees.
Prune the tree first, in the very early spring or very late winter when foliage is at its thinnest. This will take care of some of the ball moss first and make the job easier.
Spray the ball moss with a potassium bicarbonate (an organic fungicide that works on ball moss, as well as powdery mildew) mixture according to the packaging directions. You can also use a copper-based fungicide which you can find in most gardening centers.
As the ball moss dies--usually within five to seven days--it will lose its hold on the tree branches. Wind and rain will cause most of the ball moss to fall to the ground. Remove the remaining ball moss by hand if there are still quite a few clinging to the branches.
Prevent ball moss from taking over your trees by pruning and trimming your trees, keeping deadwood to a minimum.
