Nena from Midlothian, Illinois writes
The instructions say to use 1 oz of concentrate per inch distance around the tree. My tree is 36” at the smallest part of the trunk and 46” at the very base, but the diameter is about 12”-15”. Around the trunk to me sounds like circumference, but many of the answers on this page say diameter. So which is correct?
We apologize for any confusion. Per the product label, use 1 oz of Bio Advanced 12 Month Tree and Shrub Protect and Feed II Concentrate for every inch of distance around trunk so that would be the circumference around the tree.
