Humics are the most natural and organic way to provide plants and soil with a concentrated dose of essential nutrients, vitamins and trace elements. They are complex molecules that exist naturally in soils, peats, oceans and fresh waters. The best and most concentrated sources of humic acids are derived from a compressed organic compound known as Leonardite derived from fresh water deposits. Leonardite is the completely decomposed remnants of living organisms derived from 70 million years of humification. Like manures and other organic compounds are used to build richly fertile compost, so too Leonardite is the end result of nature’s own composting derived at a time when the earth had minimal pollutants. As a comparison, Peat is derived from only a few thousand years of decomposed organic matter. Plant Dr Humic will help you grow plants like never before.

Q. Is the powder 100% soluble?
A. Yes, but it may take a little bit of mixing to dissolve. I suggest pre-mixing it in a small jar or mug first as it takes a little bit to dissolve. Fill the jar up with about 100-150ml of water, then mix, tip into the watering can (or application device), there will be some powder still stuck to the jar, so I add another 100-150ml of water and mix again. Continue doing this until all dissolved.

Fantastic results, will definitely be purchasing more down the track. Only need a small amount if applying with a pressure sprayer.

Using in conjunction with other PDr products. Mixes well after making 3L batches. Soil activity has really improved. Will continue to use in lawn mix.

This stuff is great. As I use a backpack sprayer to apply I mix amount I need in a bucket with a few liters of water, mix with a stick and then while preparing my other plantdoc products it dissolves completely. This has brought great balance and health to the soil. Seen an increase in worms which is great. Grass seems to be less brown and less sunburn spots in the hot days.

By: Mathew on 4 November 2018
I mix with luke-warm water to make it soluble and add to other plant doctor products, my root growth has been fantastic since using this product.

Been using this on my lawn for a few months and it has helped the soil microbiology. I have a premdominate sand based and now I get small mushrooms which indicates excellent health. Mixing with a stirer/while mixing is key as it can clump otherwise
By: Ashley on 11 October 2018
Been using this product for over 3 months on lawn and vegetables. So far results seem great.
Only negative would be that it is difficult to mix up. Not that soluble.

First time owning lawn. Gave the team at plant doctor a ring and they supplied me with a wealth of information. Products turned up quickly.
Will definitely be getting more 8 weeks difference been using stimulizer, activ8mate, soil wetter, seaweed secrets and champion fertiliser. Was super fast delivery.
Amazing products!! The results are excellent and the prices are even better! Postage was only 2 days as well. Highly recommended!
Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
