Did you notice? Summer began a little while ago, but it began quite late. We had a very wet, cool spring. This year, as the spring continued to hang on well past the official start of summer, we received large volumes of phone calls and email regarding plant diseases. In some cases, these diseases had not been seen on the particular plant in question ever before. Diseases flourished in this cool wet weather and especially flourished when this weather persisted, not allowing plants to dry out. Some of the diseases that were brought to our attention included: Twig Blight on Atlas Cedars, Septoria on Poplars and Cottonwoods, Verticillium Wilt on maples, Shothole (Coryneum blight) on Plums. These were just a few of the many that came to our attention. At this point, Whitworth Pest Solutions and our Tree Care customers whose plants have been affected by these diseases are hoping to continue to get some extended dry periods that will help minimize or even kill some of these diseases and allow plants to recover.

Birches, maples, oaks and other tall trees are susceptible to aphid infestation during the growing season. The dripping you are seeing is a sticky substance that the aphids excrete while sucking on the leaves. This substance is not only annoying but can be damaging to patios, decks and automobiles.
We can help you prevent this problem by treating your trees now. One injection of a systemic insecticide in February will give you year-round aphid control. Call us for a free quote.
It was very nice to see everyone that came to the pruning class in December.
Once again, we lucked out with the weather. Although it was very cold, it remained dry throughout the day. As in past years, the class started inside and then moved outside for some hands-on experience. I hope everyone in attendance left with a better understanding of proper pruning techniques to try out on their landscape.
If you were unable to attend this class, please watch for an announcement of the next one in our fall 2010 newsletter. In the meantime here are a few tips to help you prune trees properly:
First, decide why you are pruning the tree. If it is because the tree is too big for the location and you want to make it smaller, the tree should probably be removed.
Before beginning, visualize how you want the tree to look when you’ve finished pruning.
Remember to never remove more than 1/3 of the living tree tissue in one year.
Begin by removing large limbs first.
Remove all diseased, broken, or dead branches.
Remove crossing or interfering branches.
For fruit trees, thin out the middle of the tree to allow better air circulation and light penetration.
These are just a few of the basic rules for proper pruning that will encourage a beautiful and healthy tree.
We’re pleased to announce that we now offer one-on-one pruning lessons. The charge is $150.00 for a one-hour class. It includes consulting on what needs to be done specifically in your landscape, and hands-on instruction of proper pruning techniques. If you are interested in setting an appointment, please give our office a call.
