Aquatic Compost 35L bag - By Jamieson Brothers

Fungus gnats are a common frustration with many mass-market composts, but we take plant health seriously. Our compost is professionally screened and stored in a clean environment to ensure it is free from infestations. By choosing our specialised mix, you are making the correct decision to keep your home pest-free while providing your plants with a clean, healthy start.

Creating a healthy pond environment starts from the bottom up—and standard garden compost just won't sink to the occasion. Our Jamieson Brothers Aquatic Compost is a heavy, grit-enriched 35L blend specifically formulated to stay exactly where you put it: at the base of your pond. Designed for water lilies, marginals, and oxygenating plants, this loam-based mix provides essential stability and controlled-release nutrients without leaching into the water or triggering unsightly algae blooms. It’s the professional choice for maintaining a balanced underwater ecosystem while ensuring your pond remains crystal clear and your aquatic life thrives.

A common complaint with cheaper alternatives is finding "green waste" or unwanted seeds in the bag. Our Aquatic Compost is a refined, high-quality medium that is strictly monitored for purity.

You can be confident that you are receiving a consistent, professional-grade product that contains only the nutrients and structure your houseplants need, with no unwanted surprises or contaminants.

Inferior composts can often arrive bone dry or as a fine dust that is difficult to water. Because our mix contains John Innes, it has a much better physical "body" and weight. This helps it retain the correct amount of moisture without becoming waterlogged or dusty. It is easy to handle and provides the perfect air-to-water balance that is essential for the delicate roots of indoor varieties.

Buying a “bargain” compost often leads to the hidden costs of replacing pond plants, cleaning cloudy water or repotting plants in a more suitable medium. Our Aquatic Compost is an all-in-one professional solution. Its heavier, stable structure helps anchor aquatic plants while creating suitable growing conditions around their roots without behaving like ordinary garden compost.

It is the most reliable choice for planting and repotting aquatic plants in ponds and water features.
