Chlorosis
Our designers and estimators have been noticing that birches and maple trees have been affected by leaf chlorosis. Chlorosis is a yellowing of the leaves with dark green veins. This is caused by nutrient deficiency in the soil or a high alkalinity or Ph level. It could also be due to damage or compacted roots or poor drainage. If left untreated, the tree will be unhealthy, it’s growth will be stunted, and it could die. If the cause is a root issue, core aerification, tiling, or mulching could be possible solutions. If the problem is the soil, there are trunk applications that could last for several years, but they do take a few weeks to see results. There are also soil treatments that could be done, but a soil test should be taken first.
Spraying for Weeds in the Fall
If you want to have a great lawn next year, the time to spray for weeds is the fall. Weeds start to grow in the fall, then go dormant over the winter, and fully emerge the next spring/summer. If you know you have an issue with specific weeds every year, such as dandelions, chickweed, or henbit, you can spray for them when they are growing back with the warm days and cool nights that fall brings. If you have any spots where the weeds grow in clusters, or areas of your yard that are prone to weeds, this is where you should focus your spraying. Make sure you use the proper herbicide, and determine the right time as well, if you are spraying pre-emergence or post-emergence.
