Hi Weezie,
I had to do a little research to find out just what is in Spray n' Grow. Bottom line: You pay a lot of money for very little.
plants use mostly macro nutrients (nitrogen, phosphorous, and potassium), minor nutrients (in small quantities) and minor or micro nutrients (trace elements) in very tiny quantities. Quality fertilizers are complete. That means they contain ALL of the essential nutrients. Check the fine print of a fertilizer label to see if it ontains mico or trace elements. If it does, then that is all you need.
Spray n' Grow contains only two of the meicronutrients and nothing else, none of the more important macro nutrients. So you have to use the stuff in addition to a fertilizer that has all of the nutrients except zinc and iron and that is very hard to find. It is also expensive.
The whole fertilizer,
plant food ,
plant nutrient business is vastly over rated. The claims made are outrageous and prey on people's ignorance of what
plants really need. Most
plants are grown in potting mixes that have more than enough nutrients to supply a
plant until it needs fresh soil.
The manufacturers never tell you that the hazards of over fertilizing are far greater than under fertilizing.
For those who want to know more on this topic, I have written an article on
plant foods that I will email to anyone who emails me a request at
