The Consequences of Hail

The damage that hail does to our homes and cars is easy to recognize and annoying to deal with. Unfortunately, hail damage doesn’t stop there. Trees, shrubs, and flowers are also vulnerable to the damage that hail inflicts. With the frequency and intensity of the recent storms, we will no doubt be finding evidence of hail damage on trees very shortly. The most obvious sign of hail damage in trees is found on the

leaves. Tears, holes, and breaks in the tissue will begin to dry out and brown margins will develop. As the tissue dries, it dies out, stops producing chlorophyll, and becomes non conductive. These damaged leaves may eventually fall off, leaving the tree with the responsibility of producing new tissue that will keep the tree living. One year of repeated hail storms is damaging to the tree, but several years of hail will continue to impact the tree and its amount of stored energy. The stored energy allows the tree to replace damaged tissue, but when the stored energy is depleted the tree will start to show signs of decline. It is very important for the tree to rebuild energy reserves so that it can withstand the next summer of hail storms.

Leaves aren’t the only part of the plant that is damaged in a hail storm. Twigs and branches are also damaged by hail. When the hail slams into twig tissue it opens up wounds that become entryways for pathogens. The most frequent pathogen that enjoys the opportunity that results from hail damage is a fungus known as Cytospora. There are many species of cytospora, but the one that affects Spruce trees in Colorado is one of the most aggressive. Cytospora is carried in the dust and rain particles during storms. When the spores land on open tissue they invade the vascular tissue and begin clogging the plants conductive tissue. Over time the tree will shows symptoms of the infection. Sparse needle canopies, twig dieback and short needle size are all symptoms of an infection. The most apparent sign of an infection is evident in the blue colored sap discharge. When the tell-tale discharge is noticed, it’s time to make a decision about what course of treatment option is best. This decision is best made on a case by case basis with the help of your friendly neighborhood Arborist.

An article posted on the website, Boulderdaily.com boasted a headline that read, “Nearly all walnut trees like to die.” This may seem like a rather dramatic statement but it may indeed come true. A pathogen is being transmitted by a very small beetle that enjoys attacking Walnut trees. To date, hundreds of majestic Black Walnut trees have been infected and subsequently removed in Colorado. Hundreds, if not all, will soon fall to the insect and its virulent disease. Homeowners with Walnut trees on their property are urged to be proactive. Control programs are available to help lower the chances of an attack and infection. Unfortunately, it is essentially impossible to save a tree after an infection has occurred; therefore, we must spread the word about this disease in order to have a chance of saving some of our beautiful Black Walnuts.

Tree Doctor Tip ~ Turf Issues: Our lawns have greatly benefitted from the extreme amount of rainfall since May. I’m sure I’m not alone when I say I have been mowing my grass almost twice a week for the first time I can remember. Rainfall amounts for May and June have been several times over the normal precipitation. The excessive rainfall has increased the occurrence of a few turf pathogens, including leaf blight and ascochyta. As the temperatures increase and the abnormally heavy rainfall decreases, the symptoms of these diseases will dissipate. At the height of their damage, these pathogens can create very large dead and brown spots all over your lawn. If you notice anything unusual in your turf, let us know about it.

  Japanese Beetles on the prowl.  

Be on the lookout for
Japanese Beetles!

Summer has finally arrived and we expect to be finding more Japanese Beetles than ever before. The adult beetle is easy to recognize. The adults have a hard green metallic shiny covering on their wings. Their appetites allow them to enjoy the nourishment of every plant ranging from herbs to trees and everything in between. These pests will defoliate their host without regard to the impact they make on the trees. Heavy infestations can severely impact the largest and healthiest tree. The larva stage of the Japanese Beetles is also damaging to plants. These grubs live in the soil and devour the roots of turf, shrubs, and flowers. The adult populations can grow to numbers that remind us of a Hitchcock film. Be sure to inspect your gardens in the coming weeks and let us know if you find this pest making a home amongst your greens.
