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.
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.
Osmocote Exact Mini 3-4 month is ideal for faster rooting softwood cuttings. Ideally used with a specific low nutrient propagation growing media.
Use Osmocote Exact Mini 5-6 month for slower rooting Semi-ripe and Hardwood cuttings.

Osmocote Exact mini can also be topdressed after rooting, great for those batches of cutting where potting on has been delayed or no Osmocote was added at sticking.
