Roots Organics Lush, Potting Mix, 1.5 cu ft

Water-Only Fertility Mix for Mature Flowering Plants, 1.5cuft

Feeding a container by hand every few days is a maintenance burden that grows with every additional plant in a garden, and it's one many growers would happily trade for a mix that carries its own fertility. Roots Organics Lush is built around that trade: a precise ratio of peat, coir, perlite, pumice, and worm castings amended heavily enough that most plants can run on water alone for roughly eight weeks before needing added nutrition.

This 1.5cu ft bag is compost-free and NPK 1-0.5-0.5, drawing its fertility from earthworm castings, dolomite, rock phosphate, bat guano, langbeinite, feather meal, fish bone meal, soybean meal, fish meal, blood meal, crab meal, alfalfa meal, kelp meal, and a handful of other natural amendments rather than from compost.

Key Features & Benefits

• Compost-free amended formula — peat, coir, perlite, and pumice base carries the fertility instead of compost
• Feeds up to eight weeks on water alone — most plants need no added nutrition during that window
• Heavily amended nutrient package — earthworm castings, bat guano, feather meal, kelp meal, and more supply sustained fertility
• NPK 1-0.5-0.5 — a mild base ratio suited to a slow-release, water-only feeding approach
• Ready to use — place directly in a container or cut open the bag and plant straight in

Who Should Use Roots Organics Lush

Gardeners growing mature flowering plants who want a heavily amended, reduced-maintenance mix suited to a water-only or minimal-feeding schedule will find Lush fits that approach.

About Roots Organics

Lush is one of the more heavily amended mixes in the Roots Organics catalog that Aurora Innovations has built out of Eugene, Oregon since 2000, aimed at growers who want a mix to carry most of the season's fertility on its own.

Frequently Asked Questions

How long can plants feed on Lush without added nutrients?

Most plants can run on water alone for roughly eight weeks before the mix's built-in fertility needs supplementing. Exact timing depends on container size, plant size, and how heavy a feeder the specific crop is.

Is this mix compost-free?

Yes, Lush draws its fertility from a peat, coir, perlite, and pumice base amended with earthworm castings, bat guano, feather meal, and other natural inputs rather than from compost. That keeps the nutrient release more predictable than a compost-based mix.

How do I use it?

Place it directly in a container with drainage, or cut open the top of the bag and plant straight into it. No additional amending is needed before planting.

What is the NPK?

Lush carries an NPK of 1-0.5-0.5, a mild ratio suited to slow, sustained release rather than a quick nutrient spike. That mild ratio is part of what lets it support plants for weeks on water alone.

When should I start adding nutrients again?

Once the eight-week water-only window has passed, or sooner if a plant shows signs of running short, start layering in a standard feeding program. Picking that program back up is what carries the plant forward once Lush's built-in fertility runs down.
