This unique formula is a ‘Trade Secret’ and has been invented by Plant Doctors founder, Daniel Fitzhenry, with unbelievable results. Stimulizer has been used by Hydroponics’ Growers and professional growers across Australia and the world. It is an immediately available form of food, both to the plant, and the soil microbes needed for a healthy soil. Stimulizer eliminates root rot diseases under certain conditions and stimulates roots unlike any other known product. Stimulizer is compatible with a wider range of materials, whether they are acidic or alkaline. Arguably, Stimulizer is the most valuable input in creating a healthy well-balanced soil for plants to thrive in. It is also described as the ‘missing link’ in plant nutrition.

Great for healthy lawns

Bought this with some other PD products as part of trying to reduce my retic use and keep my lawn healthy. Sprayed a couple of times already in my spray mix and can see the soil is retaining water longer and leaf colour and density doesn’t fade as much. Great to help hold onto water and nutrients, and for the normal residential lawn a bottle lasts a long time!

Simply Amazing

After adding a very small amount of stimulizer to each of my Plant doctor mixes, the results have been amazing! The Grass is so heathly, and the soil and root system has really become fertile and holds moisture even in our WA hot summers!. Using this product each time I apply seaweed Secrets, and active8 it has really taken my lawn to the next level! Would highly recommend using this in combination with other Plant Doctor Products with an overall turf care management plan. Thanks Plant Doctor!!!

What a bang for your buck this is. 3ml per 100sqm, I put this in with everything. Every time something in sprayed on my lawn stimulizer is in the mix. I has made a world of difference especially in conjunction with products like liquid iron, seaweed secrets and Acti8mate. Another staple with her spray.
