Frequently Asked Questions

How do I use Root & Grow Root Stimulator?

Dilute the concentrate per the label rate and apply at transplanting to stimulate early root formation. It's formulated as a fertilizer plus IBA growth hormone concentrate rather than a standalone fertilizer.

What does the IBA growth hormone do?

IBA is a root-forming hormone that stimulates early and strong root development. That's part of why this product is positioned specifically for transplant situations rather than as a general feeding fertilizer.

Will this help with transplant shock?

Yes, the label states it reduces transplant shock and promotes greener, more vigorous plants after transplanting. Reducing that setback period helps new transplants establish faster.
