Have you met the Emerald Ash Borer?

In January of 2017 I attended the Northern Green, an annual green industry get together, and it’s Master Classes for tree geeks. The dangers of standing ash trees falling apart due to heavy infestations of emerald ash borer (EAB), was one of the main themes of the conference. The effect of EAB, an agrilus beetle […]

  • Q: How do we start working on my trees?

    Usually in one of two ways:

    • An arborist stops by and looks your trees over and leaves a proposal.
    • An arborist meets with you to hear your concerns, assess the job, hand you a proposal and goes over the proposal with you.
    Either way, the proposal will outline the exact work to be done, and the price for each service item.

  • Q: Can I prune my trees in the winter?

    Winter is an excellent time to prune trees. After leaves fall branch structure is more obvious and pruning can be more effective. Although in some winters with heavy snow cover it's difficult to get a good clean-up job.

  • Q: How can you tell which branch is dead?

    Many signals of branch health are apparent in the fall and winter months. Branches lacking any bark are the most obviously dead. Branches with loose bark can be dead or perhaps dieing. Branches without the small twigs on the end can be dead, or the branch may be a live stub in which case it should probably be removed. Branches without buds on the ends of the twigs are dead. The least obvious sign of a dead branch is a branch with buds that are dead, dry or under developed. Dead buds on some tree varieties in the Midwest, such as locust, are even frustrating for experienced arborists to determine. To further complicate matters branches with leaves on in the winter (such as Norway Maples) can be newly dead.
