I have St. Augustine (floratam) lawn in S. FLorida where the temperature never really drops below 50 for more than a few days at a time. It seems like weeds never stop germinating. Does it make sense to apply this product more than once in spring and fall? How much time should I leave in between? Thank You
When using Hi-Yield Weed and Grass Stopper with Dimension, you can either do more frequent applications using less product, or you can use higher rates and apply less frequently. There is an annual maximum rate that you can use, however, so if you are still needing additional weed control, then you may need to alternate with a different pre-emergent product. There is a maximum single application rate of 9.2 lbs per 1000 sq ft, and an annual maximum of 27.6 lbs per 1000 sq ft per year. The 4-4.7 lb rate will give you 3-4 months of control, so if you used that rate 3-4 times annually then you would still be within the annual range. Keep in mind that not all weeds can be controlled with Dimension, and not all plants can be controlled with any pre-emergent herbicide. So for the best treatment plan, be sure you have identified all the target weeds so you can have a comprehensive treatment plant. Let us know if you need further assistance!
