Have you trimmed your Elm and Oak trees? Stop what you are doing and pick up the phone; time is limited to trim these trees. April 1st usually marks the end of this trimming cycle, unless colder temps (below freezing) continue. See the winter tips for more information.

With the warm spring weather approaching the trees will begin to break their dormancy. During this time the new foliage is fresh and vulnerable to fungal infections. Quite often the symptoms of fungal diseases do not appear until well after the initial infection begins. Many of the most common fungal diseases can be prevented with properly timed applications of fungicides. Diseases such as Apple Scab, Powdery Mildew, Rust, Anthracnose and the many leaf spot diseases begin in the early spring when the temperatures are cool and the spring showers wet the buds, leaves, and flowers. High humidity, fog, and cloudy days help with the spread of fungal diseases.

Remember, when you see the symptoms of fungal diseases, the plants are already infected. Infected plants will continue to spread the disease to new foliage on the plant as well as other susceptible plants in the area as long as conditions favorable to the disease are present. For treatment information please check out “Spraying” under the Services tab.

This is also a good time to do new plantings. Make sure you check with the nursery to see which trees grow best in the space allotted to the sapling. You can also consult an arborist for suggestions. This is money well spent when the expert can advise you on the best type of tree for your needs.
