Plant Doctor Potting Mix and Soil Improver is a granular conditioner that is blended into any potting mix or garden soil to add a range of beneficial minerals, silica and long-lasting organic matter. It comes in a 4.5L pack. The granules are not soluble in water, so they stay in the mix and last for many months.

Why you'll love it

  • It holds water inside the granule. The improver raises the water-holding capacity of a mix and holds that moisture internally, which prevents waterlogging.
  • It holds nutrients as well. The granules attract and hold nutrients, so less fertiliser is lost to leaching.
  • It feeds soil life. It helps to increase and feed the beneficial microbes in a potting mix.
  • It adds silica. Silica helps to strengthen plant cell walls, guards against environmental stress and improves the uptake of water and minerals. The blend also contains neem.

How to use it

Blend the granules into potting mix or soil before planting, at 5 to 20% of the total volume, which is 50 to 200ml per litre of mix. Use the higher end for cheaper mixes and the lower end for premium ones. For a plant already in a pot, sprinkle the granules over the surface and work them gently into the top of the mix. When planting into the ground, put them in the bottom of the hole and mix with the soil; around plants already in the ground, scatter liberally and work in lightly.
