Ball moss (Tillandsia recurvata) is usually harmless since it is unlike true moss that absorbs valuable nutrients from the trees. Instead, ball moss uses a tree as its home, not its food source. Over time, ball moss can become heavy and dense. This can cause your tree to bud less and may kill some of the branches. Whether the ball moss is harming your tree or you simply do not like the way it looks, there are ways to kill ball moss which do not require any chemicals.
Put on the garden gloves. Remove as much ball moss as you can with your hands. Use a ladder, if necessary. Landscapers often use cherry pickers. Throw the balls away in bags or take them to your local dump.
Power wash the tree. Use a low setting to wash away the ball moss. Discard the ball moss so that it does not reseed.
Mix the baking soda and water in a spray bottle. Wet the ball moss with a hose and spray it with the baking soda and water mixture. The wet moss will absorb the mixture and die.
Apply a fungicide as an alternative to the baking soda mixture. Use a fungicide that contains copper, such as Kocide 101, and is labeled to kill ball moss. Apply the fungicide according to the manufacturer's instructions.
