Organic All-Purpose Liquid Plant Food - 1G
Details
1-gallon jug — refill size for regular users. Makes up to 128 gallons.
Liquid nutrition for everything you grow — vegetables, herbs, flowers, trees, and shrubs. Broad-spectrum organic NPK plus the trace minerals and living microbiology your plants need to actually thrive, not just survive.
Most plant food is just NPK — the macronutrients plants need to grow, and nothing else. Our All-Purpose Liquid Plant Food is built around what plants actually want: a broad spectrum of nitrogen, phosphorus, and potassium, plus calcium, magnesium, silica, and the trace minerals that make those macros work. Made from real organic inputs — fish manure, fish emulsion, sea kelp, volcanic ash, mycorrhizal fungi — and finished with peppermint oil for a clean, garden-friendly scent. OMRI Listed, safe around children and pets when used as directed.

Frequently asked
What's the NPK?
Approximately 1-1-0.45 — modest by synthetic-fertilizer standards, much higher in usable nutrition because of the calcium, magnesium, silica, and microbial activity that unlock what's already in your soil.
Can I use it on edibles right up to harvest?
Yes. OMRI Listed for organic use with no required waiting period. We still recommend rinsing produce before eating.
How do I mix it?
1 oz per gallon of water for most uses; 2 oz per gallon for trees and shrubs. Shake the bottle before measuring — natural inputs settle.
Can I use it as a foliar spray?
Yes, at the 1 oz per gallon ratio. For a ready-to-use foliar option, our Broad-Spectrum Plant Spray comes pre-mixed in a spray bottle.
Is it safe around pets and children?
Yes, when used as directed. No synthetic chemicals; no waiting period after application.
How long does an open bottle last?
Roughly 12 months sealed, 6 months once opened, stored cool and away from sunlight. Some natural separation is normal — shake before each use.

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