Bayer Advanced 12 Month Tree and Shrub Protect and Feed II Concentrate is limited to 1 application per year. As long as you watered in the product and/or there was rainfall after the application, then product will still get to the root zone. For best results, keep the treated area moist for 10 days following the application.
