This is the 1 to 2mm granular grade of Plant Doctor VolcaMin, an agriculture grade clinoptilolite zeolite. VolcaMin is a natural mineral used as a permanent soil conditioner: its porous structure takes up nutrients and water, keeps them in the root zone and gives them back slowly as plants draw on them.

Why you'll love it

  • Fertiliser is stored, then released. VolcaMin charges with nutrients when they are plentiful and releases them on plant demand, much as a battery would.
  • The middle grade. The 1 to 2mm granule sits between the fine powder and the coarse 2 to 4mm grade, and suits potting mixes, seed raising and garden beds.
  • It holds water and nutrients against leaching. The crystalline structure improves water infiltration and retention and reduces the fertiliser lost to leaching or runoff.
  • It raises the soil's holding capacity. Zeolite boosts cation exchange, which improves fertiliser efficiency, and it buffers acidic soil with a mild liming effect.

How to use it

Apply once a year. Blend it into potting and growing mixes at 2.5 to 10% of the mix volume, which is 25 to 100kg per cubic metre, or dig it into the top 10 to 15cm of garden beds. When planting trees, use 5 to 10kg in each planting hole, or 3 to 5kg per tree in a circular trench. On lawns and garden beds the general rate is 25 to 100g per sqm. It blends well with compost, worm castings and fertiliser. Wear a dust mask when handling large amounts.
