Description
Perennials often stand on the field for a long time and have to cope with rain, drought and fluctuating temperatures. This peat-free mix combines fine coir as a water buffer with bark and wood fibre for air and structure.
A small proportion of clay increases the buffering capacity and gives the pot more weight, which helps to stop it blowing over. Part of the nutrition is organic.
- 35% fine coir, 25% bark, 25% wood fibre, 10% coarse coir, 5% clay
- Peat-free, pH 5.5-6.5 (indicative)
- Mineral base fertiliser supplemented with organic fertiliser
