The following is a further explanation of the Fall Lawn Maintenance Tips that may help with some of your decisions.
1. Weed Control: Pre-Emergent is a chemical that is used before weed seed germination. Early application, before September 30th, will control your winter weeds that come from seed.
Asking for help wherever you buy your turf products is critical. Make sure the weeds you are after are on the label and put out at label rate. The incorrect rate will result in very poor weed control. If you do have some weeds that were not controlled for some reason, make sure you seek a professional opinion when trying to control them. Not all chemicals are labeled for all types of turf.
2. Low Nitrogen Fertilizer: A Fall fungus that is problematic is Brown Patch.
Brown patch loves highly fertilized turf. Using a lower percent of Nitrogen, 9 or less will help to prevent Brown Patch from happening. Brown patch loves cool damp nights. When soil temperatures get below 75 degrees, and there is adequate moisture from irrigation or mother nature, Brown Patch can occur. Brown Patch is a soil born fungus. When the conditions are right, cool damp nights, the possibility exist for Brown Patch to occur. A preventative can be applied before the conditions occur. Watching your weather report will give you a good indication of soil temperature because the soil temp and the Beach Water temp at Galveston are just about the same for the Houston area.
3. Phosphorous and Potassium: These are the second and third numbers in your fertilizer analysis. Makes these two chemicals 2x the Nitrogen number and you will be promoting root growth and your plants will be stronger and healthier once spring gets here.
4. Irrigation: Place stable flat containers in your lawn area. Run your irrigation for a set time and then measure the amount of water collected in your containers. Place the container on a level flat surface and use a ruler to measure the water. Adjust the times of your system accordingly.
5. Insecticide: It is critical that the bugs you are after are on the label. Make sure and follow the manufactures rate recommendations. Ask for help and read the label. This is very important.
