Disease Update after Hail Storms


The hail and heavy thunderstorms that seemed to arrive nearly every day in May will affect our landscapes into the summer season. Several diseases that are common in many of our ornamental landscape trees often become prevalent after hail storms. Small cuts are formed in the twig tissue when hail crashes into the tree. It is then very easy for bacteria and fungi floating around in the environment to infect the wounded tree. Symptoms in the leaf and twig tissue will take a few weeks to become obvious, but by then it is too late to prevent additional stress to the tree.

Fireblight bacteria, cytospora canker, leaf spot and powdery mildew are a few of the diseases that will thrive in weather conditions that include heavy rain, hail, and high humidity. Symptoms manifest themselves in leaf tissue and can include necrotic spots, distorted leaf tissue, dead leaves, gummosis, and branch dieback. It is important to identify infections early and develop a plan to encourage a recovery in plant health. Treatments for diseases vary, and include trunk injections, foliar applications, modifying irrigation systems, pruning, and debris clean up.

MHT ~ SEASONAL TOPICS
from Craig Little
Craig LittleIt’s time to prune your Lilac bushes. As the flowers fade away it is important to prune your Lilac bushes now to promote vigorous growth and new flower bud production. Be sure to prune out the older canes that have died to encourage new sprouts from the root system. Avoid pruning more than 20% of the live growth in one season. Prune all dead, damaged and diseased material to maintain healthy and happy shrubs.

Ascochyta Symptoms
Lee's Lawn Tips:
ASCOCHYTA - The most common lawn problem
of late spring and summer

Ascochyta symptoms may develop throughout the growing season but are more common during hot, droughty periods that were preceded by cool, rainy conditions.

Large irregular patches of turf rapidly turn a straw-color and appear dead. Often times Ascochyta is mistaken for burns or fertilizer striping since it can follow mower tracks - leaving lines of damaged grass in a lawn. From a distance, the yard may appear to have a silvery sheen since it is only the tips of the blades being affected. Although the dieback within an area appears complete from a distance, healthy leaves are often intermingled within the patch.

Ascochyta Mowing Stripes
Ascochyta is usually restricted to the leaves; bluegrass crowns and roots typically are not killed. Leaves infected with Ascochyta often exhibit a tip dieback that extends about a third to halfway down the leaf blade. The margin between healthy and diseased tissue is abrupt and slightly pinched. In addition there is often a dark band between the green portion of the grass blade and the blighted tip.

The disease normally hits in the late spring and summer. It is closely tied to moisture changes, especially drought stress caused by watering restrictions or poor irrigation system coverage. However, the disease may also develop during periods of hot weather preceded by unusually wet soil conditions caused by excessive rain or over-irrigation. Frequent mowing and dull mower blades may contribute to disease severity by creating more infection sites (wounds).

Management

Ascochyta can be managed by following good lawn care practices to minimize stress in the lawn.
  • Maintain grass height between 2½ and 3 inches. Minimize excess damage of the leaf blades by maintaining sharp mower blades.
  • Mow when the yard is dry. Avoid mowing during wet weather, especially when Ascochyta is active.
  • Ascochyta tends to follow mower tracks; washing the under carriage of the mower after mowing and cutting infected areas last can help. Bagging the clippings and removing them also takes infected material away from the lawn.
  • Try to maintain even soil moisture. Check the irrigation system to make sure all sprinkler heads are working properly and insure water is being distributed evenly to avoid drought stress. Extra watering of Ascochyta infected areas is the best way to help grass outgrow the disease.
  • Turf usually recovers completely after a couple of weeks with extra water being applied to damaged areas. Watering deeply less often is far better than more frequent shallow watering. Keep in mind humidity levels are normally very low in Colorado, so the first several minutes of watering often does not get a chance to get into the soil.

Although several fungicides will inhibit Ascochyta growth, they can be expensive and difficult to apply. Furthermore Ascochyta leaf blight development is sporadic and rapid, making timing of preventive fungicide applications all but impossible.

Update on a Montclair Project:

We thought we’d show you an updated photo of a project we did in 2011 – we installed a new walkway, replaced ugly Juniper trees with beautiful front gardens, and put in a flagstone walkway to a side garden. We also yanked out Junipers in the front of the house and planted trees, shrubs and perennials. Check out how the plants have grown, and notice how green and weed free the lawn is. We have been fertilizing the lawn with our Nature’s Way organic fertilizer since 2011 and the lawn has never looked better! We would enjoy helping you create an outdoor space for your lifestyle too.

Colorado Springs Tree PlantingHail Damage in Colorado Springs

A swath of Colorado Springs was damaged by hail on May 21. A strong storm with 50 plus mile per hour winds and damaging size hail blasted through the Broadmoor, Ivywild, Downtown and the Old North End. It broke windows, damaged roofs and cars and stripped trees of their foliage. Spring is a critical time for defoliation to occur. Having just put out leaves and in many cases flowers, many trees are at a low in carbohydrate reserves. This makes it difficult to flush a second set of leaves, yet most healthy trees are able to do just that.

Moisture and nutrients are important in helping a tree put out a new set of leaves and to form wound callous around the small wounds on their branches. It is also important to prevent further defoliation of your trees by damaging insects.

If you would like an inspection of your trees or get set up for a fertilization or appropriate insect control, call our Colorado Springs Office at 719-444-8800.
