Last Fall I planted a Nikko maple (Acer maximowiczianum) for one of my neighbors. Somewhat uncommon, Nikko maple is a small statured, 20 - 30’ at maturity, trifoliate, hardy tree with nice fall color. It has good urban tolerance and was a good fit for its location with overhead utilities. I have been watering this tree somewhat regularly with a large watering can that I can easily carry across the street and have been pleased with the healthy appearance and good amount of new growth that has emerged this year. As far as I could tell the tree looked great so you can imagine my surprise when I came home recently from a long weekend getaway and discovered that the top half of the tree’s canopy had turned brown.
When and How to Prune Lilacs
Common lilacs (Syringa vulgaris) are a favorite landscape shrub here in Ohio and beyond, with flowers that provide beauty and an unmistakable fragrance every spring. Other cultivars of lilacs offer different habits and uses in the landscape, but provide the same display of flowers that we all love. In order to ensure you get the most flowers on your lilac year after year, it’s important to know when and how to prune them.
Don’t Get Fooled by the Fall Color of Conifers!
Every fall I get calls from folks concerned about yellow needles on their evergreen trees. Often times I’m told that the trees are sick or that they appear to be dying from the inside out. There are some disease and insect problems that can cause yellowing and premature loss of needles in conifers but most often what people are reporting is just normal fall color.
Are Your Trees Being Suffocated By Their Own Roots?
More and more trees are growing up in confined urban environments that force their root systems to wrap around the base of the tree causing girdling roots. Girdling roots will block vital nutrients to flow to the tree's canopy which can eventually cause the tree to die. The good news: girdling roots can be fixed if caught early!
