Plan Now for Summer Pests
The time to treat pest infestations and diseases in your landscape is before they occur. And early spring is a good time to start with a program of Integrated Pest Management.
The Bristlecone Pine
Bristlecone pines are tough customers. They grow where nothing else will and last for centuries. In fact, a Great Basin bristlecone pine in California’s White Mountains has been calculated as being 5,067 years old, making it the oldest known individual tree on earth. Clonal colonies of plants and microorganisms can last for 10,000 or more years—the Pando colony of quaking aspens in Utah, for example—but when it comes to individual organisms, the bristlecone is champ.
Be Careful With Deicers
With recent heavy snows and record low temperatures, it’s important to remember that misuse of chemical deicing compounds can cause serious damage to your trees and plants. And you might not know how much damage they’ve done until spring when grass, plants and trees are dead and walks and driveways are riddled with pits and cracks.
