Confused about cumulative height
I have 200 feet run of 8 ft ficus hedges that are getting attacked by whiteflies. How much do I need to apply to soil?
You will need to know approximately how many individual ficus you have and multiply that by 96 inches (8 ft) to get the cumulative height measurement. This is how you will determine how much product you need to apply to the soil for white fly. You will need to use 1.6 oz of Adonis WSP for every 24-48 inches of cumulative shrub height.
