Organic Liquid Compost - 32oz (Case of 12)
Details
Case of 12 × 32oz — retail-floor pack for garden centers.
Composting without the pile. Liquid Compost is a fast-acting soil amendment built from fish manure, sea kelp, volcanic ash, and mycorrhizal fungi — the nutrition of finished compost in a bottle, ready to go to work the moment it touches your soil.
Real composting is slow, smelly, and requires turning. For most gardeners, the math doesn't work — you need the result, not the project. Liquid Compost gives you the result. Made from high-quality organic inputs (fish manure, fish emulsion, sea kelp, volcanic ash, mycorrhizal fungi), each bottle delivers a broad spectrum of nutrition — nitrogen, phosphorus, potassium, calcium, magnesium, silica — alongside a living microbial community that improves soil structure season after season. OMRI Listed for organic use. CDFA approved. Made in the USA.
Results
Faster establishment after transplant or seeding. Healthier root systems and visibly thicker top growth. Better water retention as soil biology improves. Suitable for annuals, perennials, trees and shrubs, lawn and turf, and field crops.
Ingredients
Fish manure, fish emulsion, sea kelp, volcanic ash, mycorrhizal fungi. Broad-spectrum NPK plus calcium, magnesium, and silica. No synthetic additives, no chemicals, no fillers.
How to use
Landscaping: drench the root zone during new plantings, transplants, or seasonal cleanups; repeat every 2–4 weeks during active growth. Fields & pastures: apply prior to, during, or after each crop cycle. Established gardens: use every 2 weeks during active growth. Foliar option: dilute and apply through a sprayer for faster correction of nutrient deficiencies.
Frequently asked
How is this different from a compost pile?
A compost pile takes 3–12 months to finish and needs turning. Liquid Compost delivers the same broad-spectrum organic nutrition and microbial community immediately — no pile, no turning, no waiting.
Will it smell?
Mildly, on application — it's made from fish. The smell dissipates within an hour. For indoor or balcony use, our Indoor Houseplant Food is finished with peppermint oil for a cleaner scent.
Can I use it on edible plants?
Yes. OMRI Listed for organic use and safe on all vegetables, herbs, fruit, and edible flowers. No waiting period required before harvest; we recommend rinsing produce before eating.
How do I dilute it?
For soil drench, 2 oz per gallon of water. For foliar spray, 1 oz per gallon. For new transplants, water in lightly after application.
How often should I apply?
Every 2 weeks during active growth, every 4 weeks during dormancy. Field crops: prior to, during, and after each cycle.
Is it safe around pets and children?
Yes, when used as directed. No synthetic chemicals, no toxic inputs. No waiting period after application for lawns or play areas.

How to use Organic Liquid Compost
Three simple steps — no expertise required.
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.
Apply
Drench the root zone, mist the leaves, or work into soil — depending on the product. Water in lightly when applying to soil.
Repeat
Most products: every 2–4 weeks during active growth. Reduce or skip during dormancy. Biochar is a one-time application — permanent.
