Question 1

When is the best time to trim trees in Central Texas?

Accepted Answer

For most species, late fall through winter, while the tree is dormant and its structure is visible. Oaks we take year round, because what protects an oak is sealing the cut as it is made and cleaning tools between trees, rather than the month it is done in. Full detail in when to trim oak trees in Texas.

Question 2

How do I know if a tree has oak wilt?

Accepted Answer

Look for veinal necrosis, where the veins of a live oak leaf brown while the tissue between them stays green, and for leaves dropping while still partly green in summer. The strongest clue is several nearby oaks declining together, because the fungus moves through interconnected roots at 75 to 100 feet per year. Red oaks typically die within four to six weeks of infection. See our oak wilt questions and answers.

Question 3

How much of a tree can be pruned at once?

Accepted Answer

No more than 25% of the canopy in a single year, and less on a tree already carrying drought stress. Cuts belong just outside the branch collar, and it is best to avoid removing branches larger than four to six inches in diameter where you have the choice.

Question 4

Why do trees fall here when they looked healthy?

Accepted Answer

Thin soil over limestone means trees anchor with wide, shallow root plates rather than deep roots. Saturated ground plus wind lifts the whole plate, which is why Hill Country failures cluster after heavy rain rather than in drought. Long overextended limbs make it worse by adding leverage.

Question 5

Does clearing cedar on my property stop cedar fever?

Accepted Answer

No. Ashe juniper pollen travels a very long way on wind, so most of what affects you in January did not come from your land. Clearing is still worth doing for water competition, fire fuel and access. See cedar fever in Central Texas.

Question 6

Should pruning cuts be sealed?

Accepted Answer

For most species no, because wounds close better uncovered. Oaks are the exception and it is not a marginal one: seal oak cuts promptly, year round, with a wound dressing or plain latex paint. Do the same for accidental bark damage from a mower or vehicle.
