Description
Made for nursery stock and other container crops that are grown outdoors, sometimes over several seasons. Bark and coarse coir fibre provide plenty of air-filled pores and a structure that does not collapse, not even after a wet winter.
A coated controlled-release fertiliser releases nutrients over a longer period, supplemented by a small starter dose for the first few weeks.
- 30% white peat, 30% bark, 25% coarse coir, 15% wood fibre
- Fraction 0-40 mm, coarse
- Coated fertiliser with a stated longevity of approx. 8-9 months; other release periods available as a bespoke mix
- Only available in bulk: loose or in big bags
