“Well balanced product can be used on many crops”
"I like Dr Forest's general-purpose feed, which is organic, made here in the UK, and full of good stuff."

Named after my grandfather Dr Forrest.
Dr Forest is named after my grandfather, Dr Forrest, a GP from a mining town near Preston. Off-shift he kept a back-garden plot growing runner beans for the piccalilli he made for family and friends.
We've taken the evidence-based approach of medicine and applied it to soil, guided by peer-reviewed science, not dogma. Every batch is hand-blended here in Stockport. No mystery NPK fillers. British-sourced minerals where possible, organic plant meals and microbial biology. Every ingredient named on the bag.

Soil-first. Organic always.
Every Dr Forest blend is built around British-sourced minerals, organic plant meals and live microbial biology, feeding the soil so the soil feeds the plant.
It's slower than synthetic NPK. It works for longer. And it leaves your soil in better shape every season, the way good gardens have always been made.

I decided to try granular potash to take some of the strain from regular watering. I can’t recommend this product enough. My fruit trees and flowers are thriving with little effort from me. I’ve made some bags up for family and friends and they’re impressed with the product. A little goes a long way. It’s clean and easy to use. The potash was delivered shortly after ordering. I would definitely order from Dr Forest again.
My shrubs, herbaceous plants and lawn seem generally healthier, lusher, more floriferous, and I think larger flowers. Also an efficient service.
I’ve used Dr Forest potato fertiliser on multiple varieties of normal potato and sweet potatoes. I’ve noticed the foliage has exploded, the stems are nice and thick as well. Another great product from Dr Forest. Great service and great knowledge about what fertilisers you need. Get some before it’s gone.
Well packaged, showed up on time and my plants love it as both a mulch layer as well as broken down to make new living soil mix, will buy again and maybe other things I need as well.
Good quality and slow-release no-till amendment, also very easy to use. I would definitely recommend to other growers.
I didn’t want to rely on harsh chemicals to feed my roses, I appreciate that Dr Forest Premium Rose and Flower fertiliser is both organic and sustainable, looking after the soil and the roses, slowly releasing nutrients. I’ve used this food for two seasons now, I noticed how well my roses were growing with several flushes of blooms with good colour and fragrance.
Most-read guides.
In organic gardens you'll often hear that pH doesn't matter because the soil buffers it. Only partly true. pH drifts even in well-tended organic systems, slowing growth before you notice. How to test it, how to raise or lower it gently, and which UK plants want what.
Yellow leaves on a tomato plant aren't one problem. They're a symptom of half a dozen different things, and the right fix depends on which one. The position of the yellow on the plant and the pattern inside the leaf together name the cause. The diagnostic guide, plus a feeding programme that prevents most cases.
