Since my last blog about Spanish moss, a few people questioned this plant’s impact to trees. Many people assume that it causes damage and ultimately the death of the tree it lives on. This plant grows best on aged trees. The dead branches in older trees slough off important nutrients the plant needs to thrive. The weight of Spanish moss on dead limbs will cause the branches to fall especially with after heavy rains and strong winds; this is a form of natural pruning. But if you have one of these old trees on your property have it evaluated by a reputable arborist who can advise you one maintaining the health of the tree.
