How much of the tree do you remove in a thinning?
Never more than about a quarter of the live canopy in a season — the standard rule, not our invention — and usually well under it. Much of what leaves a typical crown is deadwood, which does not count against the tree at all.
What is lion-tailing, and why does it keep coming up?
Stripping the interior branches off a limb and leaving a tuft at the end. It is common because interior wood is easy to cut, and malpractice because it moves the load to the limb tips — the position most likely to snap. A bid promising to 'clean out the inside of the tree' is describing exactly this.
Will thinning make my tree safer in storms?
It helps, measurably: wind passes through instead of loading the crown like a sail, and the branches most likely to fail are gone. It is not a guarantee — no pruning is — and a tree with a structural defect may also need cabling or reduction, which we will say plainly at the estimate.
Will grass really grow back under the tree?
Often, if deep shade was the problem — thinning turns it dappled, and turf can live with dappled. Under a Norway maple, though, shallow roots steal water as fast as the shade steals light. When we think seeding will fail, we will tell you before you spend on it.
How often does a tree need thinning?
Every few years for a mature shade tree here, and the visits get smaller each time. Annual thinning is almost always too much — a tree that needs live wood removed every year is being over-pruned, not maintained.
When is the best season for it?
Dormant season for most species — structure is visible and the tree closes wounds in spring. Oaks only in the cold months, because of oak wilt. Deadwood can and should come out whenever it is found.
Can you just top it instead? It would be cheaper.
No. Topping is the one cut we refuse site-wide, on every species, at any price — it creates weak regrowth and decay we end up removing as a hazard years later. If a crown is dense, thinning fixes it. If a tree is too tall, reduction fixes what can be fixed. Topping fixes nothing.
