I really can’t tell much of a difference so far. I put all 3 of your products down in front flower bed and some in vegetable garden.

Very happy with John and Bob's products
I have purchased twice now. It definitely resulted in better growth and production of vegetables in 2022. I recently paid for new landscaping in Dec. I applied maximize and optimize to all newly planted trees and shrubs before the snow and rain started. Looking forward to Spring to see results.


Review Maximize
Maximize was my first purchase from John and Bobs. Results were excellent. I purchased Maximize to help my yard recover from some “brown spot” issues. I worked great. Not only did those areas recover but the entire yard turned greener and required less watering this past summer.
