How to Manage Pests

Pests in Gardens and Landscapes


Lightning most commonly strikes isolated, exposed, or tall plants. Lightning kills bark or wood in a long, vertical band and can cause plants to explode or burn. Lightning strikes can seriously damage roots even though the damage on the aboveground portions of the plant appears relatively minor.


Lightning rods wired to the ground can be installed at the top of especially valuable, tall trees in areas where lightning is prevalent. Have an expert inspect lightning-struck trees for root damage that may cause the tree to fall.
