Everything you need to know about growing plants from propagation
Grow, nurture, protect your propagated plants
Vegetative plant propagation is the process of replicating plant species from a singular parent plant, allowing growers and breeders to produce consistency within their plant stock from year to year. There are a number of plant propagation techniques, including micropropagation, division, budding, and grafting, but cuttings are the easiest and most popular.
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.

Cuttings are typically struck into small cells in a humid environment often under mist, fog or contact polythene with bottom heat. Cool tops and warm feet to encourage rooting.
Initially a low nutrient growing media is required to encourage healthy roots. After rooting nutrients are required to develop buds and further roots, any check in plant development at this stage will lengthen the production time and reduce final plant quality. Water soluble feeds are quickly leached in this production system and likely to cause moss and algal growth.

The it starts to increase, giving the established plant, enhanced release optimizing growth and giving the best quality. Quality is enhanced by the OTEA enhanced trace element system which ensure optimum levels of trace elements are available to the plants roots giving the best leaf colour. For small cell volumes use Osmocote Exact Mini 5-6m.
To keep plants free of pest and diseases ICL offer Prestop within the growing media mixes to help prevent root disease and keep plants healthy.
ICL also have a the Vitalnova range of biostimulant to help boost plant health throughout the growing season.
ICL offers standard off the shelf solutions with its Levington Advance Peat Reduced Seed and Modular or Levington Advance Sustain Peat free Modular Seed as well as bespoke Levington Advance Solutions growing media mixes as required, Bark or Perlite is often added when using mist.
Specifically developed for small cells, Osmocote Exact Mini has granules 5X smaller than Osmocote Exact, making mixing in growing media very safe and even in small plugs. A good distribution can be achieved even in volumes starting at 20 ml.
The Osmocote Exact Mini not only contains NPK but also Magnesium and Essential trace elements for optimum healthy growth.
