A month by month calendar. Cut this out and keep it.
| Dec to Feb | The main window. Best time for structural work on most hardwoods. Take out crossing limbs, clear the roof and the drive, take weight off long horizontal limbs. You can see the shape with the leaves off. |
|---|---|
| Feb to Jun | Hands off the oaks. This is oak wilt season. The beetles that carry it are flying and they are drawn to fresh cuts. If an oak has to be cut in this window, paint the wound the same day. |
| Mar to May | Watch, do not cut. Spring growth is the best look you get at a tree all year. A limb that leafs out thin, late, or not at all is telling you something the bare canopy hid. Make a note and deal with it next winter. |
| Jun to Aug | Light work only. Summer cuts slow a tree down, which is sometimes what you want. Keep it light. Heavy cuts on a stressed tree in a North Texas August are a bad combination. |
| Sep to Nov | Storm prep. Take weight off anything hanging over the house before winter, and clear whatever is growing into a service line. |
Some cuts do not wait for a season. A dead limb over the drive comes off when you find it. So does a cracked branch after a storm, or anything grown into a power line. The risk of leaving it beats any argument about timing.
Topping. Cutting the head off a tree makes it throw up weak shoots that snap in the first
real wind, and you cannot undo it.
Cutting oaks in spring. See February to June.
Taking too much at once. A tree needs its leaves. Removing more than about a quarter of a
canopy in one go is a shock it may not recover from.
