Spring Tree Care Calendar

Spring is a good time to prune winter-damaged branches, thin or remove deadwood, and prepare your landscape for summer. Check regularly for active pests and diseases, and avoid pruning oaks and elms due to insect activity.

Summer Tree Care Calendar

Water trees during hot, dry periods when rainfall is insufficient (about 1 inch per week). Monitor leaves for signs of stress like browning, holes, or early drop. Prune non-oak and non-elm trees to reduce storm damage and remove weak branches.

Fall Tree Care Calendar

Fall is a great time to prepare trees and shrubs for winter. Pruning helps reduce storm damage and improves spring growth. With leaves down, structure is easier to see, and improved soil conditions help strengthen trees against stress, pests, and disease.

Winter Tree Care Calendar

Winter is ideal for pruning since tree structure is clearly visible and there is less risk of damaging surrounding plants. Frozen ground improves access and safety, and winter pruning can also reduce exposure to certain pests and diseases active in warmer months.
