Soil conditioners include compost, manure, organic soil conditioners and other soil improver concentrates (a blend of soil improvers) and are necessary for your soil to perform at its optimum level.

TerraCottem Soil Conditioner

Each TerraCottem soil conditioner is rich in microbial life and contains a combination of water absorbing, growth stimulating and nutritive components. They all work in synergy, stimulating microbial activity, with water holding capacity adding plant nutrients and stimulating root development when mixed with soil, increasing aeration and growth even when planting in poor and degraded garden soils.


The effect is twofold: you get sustainable healthy growth & savings of up to 50% in irrigation water, even when planting your new plants under challenging conditions. TerraCottem Universal is the "original" TerraCottem Soil Conditioner, however all TerraCottem variations are suitable for a range of soil types.

Clay Soils

Clay soils tend to compact easily, which limits aeration, drainage and the soils ability to absorb and retain moisture. Adding organic matter like screened peat moss or composted organics helps make compacted clay soils more porous and improves drainage and their ability to hold nutrients and water.

Organic matter can be purchased in the form of peat moss or a rich black compost; it's also possible to add organic material like leaves, grass clippings, ground up compost, sheep/cow manure or other materials.

Sandy Soil

If you have sandy soils or sandy garden beds, you may have noticed that they don't retain water or nutrients well, leading to dry soil conditions that stress plants and make them more susceptible to disease. Using organic matter and irrigation can help sandier soils store more water and greatly increase the time between watering cycles.

Bentonite Clay incorporated into sandy soil aids soil wettability (the ability of moisture as a liquid or gas to spread out over a surface), increases water holding capacity (the amount of moisture that fills pore spaces within the soil), improves nutrient retention (adds nutrients to live organisms in a habitat) to maintain and protect and enhances biological activity (the process by which organisms interact with one another).


When adding organic matter to existing soil, make sure that it is free of weed seeds and disease organisms by purchasing only from reputable sources; ideally, try to buy locally produced material for new plants so that it hasn't been sitting around for a long time before use.

Avoid using soil conditioner and composts with a high nitrogen or salt content, or compost that has been sitting around for a long time before use (more than six months).


An organic soil improver or soil conditioners are a great way to improve poor quality soil, but they're not the only additional nutrient options. Many other organic materials can be used as soil amendments such as composts, peat moss, and cow manure. Great for phosphorus sensitive plants.
