For vigorous, easy to root species, rather than being struck into small cells cuttings can be struck into 9cm liners or even larger pots up to 1.5 litres. This shortens the production cycle and reduces costs. Many HNS plants grown for landscape planting can be grown this way, eg Rubus tricolor, Ivy (Hedera Helix Hibernica) and Cotoneaster dammeri. Pot Plants such as Geranium (Pelargonium) and Pot Mums (Chrysanthemum) can also be grown this way over a shorter crop cycle.
With this production system plants’ nutrient demands change dramatically over time. Initially a low nutrient growing media is required to encourage healthy roots. With a small cutting in a large pot, moss and algae growing on the surface of the growing media can be a problem. After rooting, the plant demand for nutrients will increase as the plant grows rapidly.
With its unique double coating Osmocote Exact High End (25% less), perfect to encourage rooting. After 6-12 weeks (depending on the longevity) there is enhanced release optimizing growth and giving the best quality.
