Treehouse Builders questions, answered by experts

No, you don’t need a pruning seal for trees post-trim. Pruning seals (applied to the cut ends of branches) are widely sold but they aren’t designed for every tree and in many cases can cause more harm. Trees have their own healing processes after pruning, so the best thing you can do is supply them with plenty of water and add some dormant-style fertilizer.

Pruning seals are primarily recommended for very vulnerable species like elm trees in areas where dangerous tree diseases like Dutch elm disease are spreading. In these cases, a sealant’s protection outweighs its downsides.

Carefully pruning small roots no thicker than three inches in diameter won’t harm the tree. However, cutting larger roots may impact the tree's stability and nutrient absorption. It's advisable to consult an arborist or tree care professional to evaluate the root's size, the tree's health, and the potential impact of cutting. Proper tree pruning techniques and timing can minimize damage, but larger root removal may necessitate expert guidance to avoid compromising the tree's overall health and stability.

Yes, pruning makes trees stronger because it fosters proper growth, weight distribution, and balance of the crown. By increasing the structural integrity of the tree through pruning, it’s less likely to experience disease, pests, broken limbs, and storm damage. Pruning the right branches and limbs is key to improving a tree’s strength and balance.

It is possible for you to cut down your own tree, but only take this project on if it’s a small tree and you’re experienced handling a chainsaw. If you need to use a ladder to cut down the tree or tree limbs, it’s too large (and dangerous) for you to remove yourself. 

Hire a pro instead who can safely remove the tree without injury to you, themselves, or your home. Either way, look into tree removal regulations for the state you live in before having a tree removed to ensure it’s not a historic tree or protected by your city.

Light-bark trees are most notorious for producing lots of sap when wounded. These varieties include maples, birches, poplars, dogwoods, magnolias, and elms, and they will bleed more when the trees are dormant. That’s why it’s a good idea to prune them in the summer months rather than waiting until winter.
