At Lawn Ranger we like to provide the best service possible. Our trained technicians are always aware of the weather conditions and use their best judgment when applying your treatments. In general, all technicians will stop applying treatments 2 hours prior to a heavy rainfall to ensure effective results. This holds true for applications that may be affected by the rain. Keep in mind, some applications benefit from the rainfall. If you have any questions or concerns whether your treatment will be affected, please feel free to call our office.
