Mulch

When and how much mulch should I apply?

 For best weed suppression, apply mulch in early spring. Remove any existing weeds before applying mulch. Mulches applied for winter protection should be laid down in early winter, before the soil has frozen. For trees and shrubs, spread mulch evenly to a depth of 2 to 3 inches. For trees and shrubs in beds, mulch the entire bed. For those in a lawn, mulch a wide ring (extending from 3 to 6 feet out from the trunk) around each plant. Never pile mulch against tree trunks. Pull mulch back away from the trunk about an inch or so. As organic mulches decompose, they may need to be replenished somewhat every year; but don't let mulch build up to depths greater than about 4 inches. For flower beds, mulch can be applied up to 3 inches deep (after settling), but should be kept pulled back slightly from plant stems. Mulches should thoroughly cover an area to a uniform depth to be most effective. Low or bare spots are prone to weed problems.
