The best time to trim most trees in North Texas is late winter through early spring, before bud break. That means January and February for most of Collin County, and into early March in a cool year. There is one big exception: oaks should not be pruned between February and June because of oak wilt.
Late winter pruning has real advantages. The branch structure is visible with the leaves off, so it is easier to see what should stay and what should go. Cuts heal fast when the tree wakes up in spring. And insect pressure is at its lowest, so freshly cut branches are less likely to attract pests.
Oak wilt is the reason for the February to June restriction. Oak wilt is a fungal disease spread by beetles that are attracted to fresh oak wounds. In North Texas the beetles are most active in the spring, so pruning a live oak or red oak during that window can invite the disease into the tree and, worse, into the whole root-connected grove. If you must prune an oak between February and June for safety reasons, paint the cut immediately with pruning sealer.
Bradford pears and other flowering ornamentals should be pruned right after they bloom in spring. Prune too early and you cut off the flower buds. Prune too late and you set up next year's blooms. Cedar elms, hackberries, and Chinese pistache can be pruned in the winter dormant window without issue.
Storm damage and safety pruning are the exception to every rule. If a limb is cracked, hanging, or over the roof, it comes off when you see it, not on a calendar. That is true year-round.
How much should you prune? Most healthy trees can handle roughly 15 to 25 percent of their canopy removed in one year. Topping (cutting the tops off large branches) and lion-tailing (stripping the interior branches) are both bad practices that weaken the tree and shorten its life. A good pruning job removes deadwood, crossing branches, and specific problem limbs, and leaves a natural-looking canopy.
