Are you growing in containers or in the ground?

Are these special microbes, or just more of what is already in your garden soil?

Using microbes, or mycorrhizae can work wonders when you grow a plant for a long period of time. It takes months for the colony to grow to the point that they are doing a good job.
The problem is that they will die of you have too much phosphate in the fertilizer you use, or most any other harsh fertilizer, for that matter. If your soil or your water is too alkaline, it will kill them. There are other things that kill them also. So bottom line, if you go totally organic and do everything right, they will help a lot. If you do anything that kills them, you are throwing a lot of money right down the toilet.

I use them, I apply monthly for any loss of the organisms.
I had really good luck with them. Growth rates are noticeably better on treated plants in my experience.
I use MycoGrow and Biota Max

MycoGrow is cheap so if in a budget, just use that product.

I've used Espoma Starter Plus with very good results. It
gave the root system a really good start. Four pound bag
was about $10.00 or $12.00
