Each box can feed 8 trees 3" in diameter. Stakes have a duration of approx 12 months and have a specially designed cap so they are easily inserted into soft soil with a small mallet. Sakes can be pounded close to the feeder roots.
The application rate is easy and can help the user decide how many boxes will fill the job. The 12 month lifespan is generous and means you are not limited to when you can apply them. The plastic drive caps reduce stake breakage, makes installing them at the surface easy; no need to dig a hole or back-fill Inserting them close to the feeder roots means more nutrient uptake and less waste.
