Frequently asked questions
-
What do you do with the wood and chips?If requested, we can leave firewood. Other debris is chipped into the back of a truck. The resulting "arborist chips" are an excellent material to spread under your tree and in gardens. As they breakdown, they give the soil added nutrients, help retain moisture, regulate temperature and reduce weeds. Ask our team about dumping chips for your garden project.
-
Can I use the wood in my fireplace?While some types of wood burn better than others, most can be used in your fireplace. Remember, that unless we are removing “deadwood” from your tree, the wood will need to dry for a season before burning.
