Chemical deicers and rock salt are useful in keeping wintery roads safe for driving, but they can wreck havoc on trees. One way to help protect trees is to be proactive: Apply salt to your driveway before winter weather strikes. When you throw deicing products on top of snow-covered driveways, the chance it can slide and spread to trees is greater. If you plan on planting new trees in the spring, consider salt-tolerant species like ashes, ginkgo, Norway maple, red oak and pines like Austrian pitch and Japanese black. They can thrive well without much damage from salt and chemical deicers. As always, simple sand is a safe bet to protect trees and make your driveway less slick.
