Organic liquid fertilisers are the fastest way to deliver nutrients to a plant — applied as a foliar spray for direct leaf uptake, or watered in at the roots for rapid soil-level feeding. They're ideal for correcting a deficiency, supporting heavy fruit set, or running a regular weekly feed alongside dry amendments. Dr Forest's liquid range is made with organic ingredients and covers everything from micronised mineral suspensions to chelated trace elements and concentrated seaweed biostimulants.
What's in the range
-
Liquid suspension fertilisers — micronised minerals (calcium phosphate, magnesium, gypsum, silica) suspended in pourable form. Easy to dose, fast to absorb, no mixing required.
-
Liquid gypsum — 20% calcium and 15% sulphur as micronised calcium sulphate. Acts as a fast-acting clay breaker and calcium source for chloride-sensitive crops.
-
Liquid silica — micronised diatomaceous earth that strengthens cell walls and improves heat and drought resilience.
-
Chelated micro-nutrients — Micro 7 delivers seven essential trace elements bonded for maximum plant availability.
-
Seaweed biostimulants — concentrated kelp extracts loaded with growth promoters, alginates and natural plant hormones.
-
Seedling root drench — NPK plus humic acid for the first weeks of growth and after transplanting.
-
Microbial liquid feeds — living soil-style foliar and root applications that combine biology with nutrition.
How to apply
Most liquids in this range work both as a soil drench (watered in at the roots) and as a foliar spray (misted onto leaves for fast uptake). They layer cleanly into any feeding programme — pair with dry organic amendments for steady release plus targeted top-ups. Application rates are on each product page.
