How to Manage Pests

Pests in Gardens and Landscapes

Whitewashing trunks

Prevent sunburn by applying white interior (not exterior) nonenamel latex paint diluted with an equal amount of water to young trunks. Whitewash trunks from 1 inch below ground level to at least 2 feet above to prevent sunburn. Borers, especially flatheaded borers, are frequently a problem on young trees whose trunks have been sunburned.
