Application guide

How to use Organic Liquid Lawn & Turf Food

Three simple steps — no expertise required.

1
Measure

Open the bottle or bag and follow the dilution rate on the label. Liquids: 1–2 oz per gallon of water. Biochar: one cubic foot per 64oz bag.

2
Apply

Drench the root zone, mist the leaves, or work into soil — depending on the product. Water in lightly when applying to soil.

3
Repeat

Most products: every 2–4 weeks during active growth. Reduce or skip during dormancy. Biochar is a one-time application — permanent.

The 3-in-1 advantage

Plants need
what you need.

Food. Vitamins. Probiotics. Most products give you one. Ours gives you all three.

Food
Macronutrients
N · P · K

Nitrogen, phosphorus, and potassium. The fuel that makes things grow. You can survive on food alone for a while — but you won’t thrive.

Vitamins
Micronutrients
Trace minerals

Calcium, magnesium, iron, zinc, sulfur. The supporting cast that makes your food actually work. Without these, even the best diet falls flat.

What makes us different
Probiotics
Probiotics
Living microbiome

Billions of beneficial microbes that live alongside roots — same principle as gut bacteria for humans. They unlock nutrients, fight disease, and keep the whole system humming.

*Dr. Earth lists mycorrhizae in their ingredient panel — viability of those microbes by the time they reach soil is the open question. Our biochar pre-loads live, active microbes the moment it hits the ground.

The science inside

300+ species.
Billions of each.
All in one bag.

Our biochar is studied in a multi-year USDA ARS field trial. Initial results suggest the curated microbial community we pre-load it with contains rare plant growth-promoting species not present in raw or uncharged biochar.
