Dr.Soil Green Compost — Sieved Vegetable Compost, 1 L

Fully matured green compost produced from plant material, laboratory tested for quality and maturity, and finely sieved to a uniform, crumbly texture. Peat-free and produced from renewable plant material. Feeds the soil food web, improves structure, retains moisture, and builds long-term fertility with every application.

What Is Green Compost?

Dr.Soil Green Compost is produced from green vegetable matter — lawn clippings, leaves, hedge trimmings, and plant residues — processed through a controlled aerobic composting cycle that generates sufficient heat to eliminate weed seeds and pathogens, break down complex organic molecules into plant-available forms, and stabilise the final material into fully mature humus. The compost is laboratory tested for maturity and heavy metal content before being finely sieved to produce a uniform, consistently textured product.

The critical distinction between green compost and an immature or unstabilised material is the carbon-to-nitrogen (C:N) ratio. In fresh or partially composted material, the C:N ratio is high and microbial activity focused on decomposition will tie up available nitrogen from the surrounding soil — actually depriving plants of nitrogen in the short term. Dr.Soil Green Compost is fully matured to a stable C:N ratio, which means it releases nutrients rather than locking them up, and supports rather than competes with the soil food web from the moment of application.

What Green Compost Provides That Synthetic Fertiliser Cannot

Synthetic fertilisers supply NPK in soluble form — immediately available to plants but equally immediately vulnerable to leaching, and providing nothing for soil structure or biology. Green compost feeds the soil rather than the plant: it supplies slow-release nutrition that is metered out by microbial activity rather than dissolving with the first rainfall; it improves the physical structure of both clay and sandy soils; it introduces and sustains the biological community — bacteria, fungi, actinomycetes, protozoa — that drives the natural nutrient cycling on which all healthy soil depends. These benefits compound over time, making each application more effective than the last.

What Is It Designed For?

Dr.Soil Green Compost is designed as the organic foundation component of any growing medium — the ingredient that provides nutrition, structure, biological activity, and moisture retention simultaneously.

• Potting and container mixes — the organic foundation of any homemade peat-free substrate blend; provides nutrition, moisture retention, and biological activity that forms the basis for all plant growth
• Garden bed improvement — worked into existing soil annually to progressively improve structure, fertility, and the biological community
• Surface mulching — applied around established plants to retain moisture, suppress weeds, and feed the soil as it breaks down
• New lawn preparation — incorporated into topsoil before seeding or turfing to dramatically improve establishment on poor or compacted ground
• Compost tea — steeped in water to produce a liquid soil drench that delivers soluble nutrients and biological inoculant to container and bed plants
• Peat-free growing — a renewable, sustainable base for all peat-free substrate blends; produced from materials that would otherwise contribute to landfill or biomass combustion

Key Advantages

• Improves soil structure — opens compacted clay soils by creating aggregate structure; binds loose sandy soils by providing the humus that holds mineral particles together; creates the crumbly, workable texture that healthy productive soil requires
• Feeds the soil food web — provides the organic carbon that fuels bacterial and fungal communities; supports earthworms, protozoa, and the full soil food web that drives natural nutrient cycling and plant health
• Slow-release nutrition — nitrogen, phosphorus, potassium, and a full range of micronutrients released gradually over weeks and months as microbial activity processes the organic matter; no leaching risk, no nutrient burn
• Improves water retention — humus holds moisture and reduces irrigation frequency; particularly valuable in free-draining or sandy soils and in peat-free container mixes
• pH buffering — moderates both acidity and alkalinity, moving the soil gently towards the neutral range at which the widest range of nutrients are most available to plants
• Peat-free and sustainable — produced entirely from renewable plant material; replacing peat with green compost prevents the destruction of irreplaceable bog habitats and the release of the carbon they store
• Progressive fertility building — unlike synthetic fertilisers whose benefit is consumed within a single season, each application of green compost leaves the soil permanently richer than it was before

How to Use

Important: Do not use as a standalone seed-sowing medium — the nutrient concentration is too high for germinating seeds and may cause damping off. Blend with a neutral substrate (coir, vermiculite, or perlite) at no more than 20% for propagation and germination mixes.

When Is It Best to Use?

Green compost is most effective applied in early spring, before planting begins, when it has the full growing season ahead to release its nutrients and improve soil structure. A second application in autumn, after the growing season, feeds soil organisms through the winter months and ensures the bed is in peak condition by the following spring. As a potting mix ingredient, use at any time of year when preparing fresh containers or repotting. The most important principle is consistency: annual application builds soil fertility progressively, with each year improving on the last.

Compatibility and Pairing Suggestions

• Dr.Soil Worm Castings — the natural complement to green compost. Compost provides the bulk organic matter and primary nutrition; worm castings add the biological complexity, plant growth hormones, and nutrient bioavailability that compost alone cannot deliver. Together they create conditions that replicate genuinely fertile, living soil. Blend at 70% compost + 15% worm castings + structural amendments for an outstanding all-purpose container substrate.
• Dr.Soil Biochar — biochar is the preferred pre-charging medium for worm castings and the natural long-term companion to green compost in soil improvement. Compost provides the organic matter and biology; biochar provides the permanent pore structure that retains it all. The combination continuously improves over successive seasons.
• Dr.Soil Perlite Grade 6 — blending green compost (30%) with perlite (20%) and coir (50%) creates a lightweight, well-draining, peat-free general-purpose potting mix suitable for most ornamentals, vegetables, and herbs.
• Dr.Soil Zeolith — adding zeolite to a compost-based mix significantly extends the effective life of the nutrition the compost supplies by capturing released ammonium and potassium and metering them out to roots over a much longer period. Less compost is needed; nutrients last longer.

Storage and Handling

Store in the original sealed bag in a cool, shaded location. Keep slightly moist — the microbial community in the compost remains active at low moisture levels and contributes to ongoing maturation, but the bag should not be stored waterlogged. If the compost has dried significantly during storage, dampen lightly before use to reactivate biological activity. Use within one to two growing seasons for best biological performance.

Fully matured green compost has a clean, earthy smell similar to healthy forest floor soil. Any ammonia or unpleasant odour suggests the material has not fully matured — Dr.Soil Green Compost is laboratory tested to confirm complete maturation before dispatch.
