I have seen this in stores "Superthrive" it's very exspensive and has anyone ever tried it and does it work? The world wants to know....as well as I. Thanks, you folks are amazing.
Every situation has specific nutrients in specific amounts that may be called for. There is no fertilizer product that is going to automatically produce a benefit every or most times it is used - that's not how it works. Same as with nutritional supplements being used by humans - if you need more of what a supplement provides, in the amount it provides it then a benefit is possible. Otherwise, not.
