It is a gel based propagation aid, which, unlike other rooting gels, is placed directly into the central dibble of the plug. Just one ml or less is sufficient to ensure rooting of softwood/greenwood and many semi-hardwood cuttings (but not acid-loving plants, such as Azaleas).
Gel4Plugs is a unique formulation and is synergistic with the plug, helping root development with minimum maintenance. It loses hydration very slowly within a moist plug and so delivers its active ingredients over a long period. This ensures maximum effect of the ingredients working the internal repair mechanism of the plant to encourage new root bud development. The thixotropic gel forms a physical seal around the cut surface of the cutting, aiding uptake and helping prevent dehydration and infection.
Gel4Plugs has obvious potential for both gardeners and commercial growers. It could be used in automated filling systems as well as manually dropping a tiny amount into each plug from the squeezy bottle. It is economical in use and, providing the plugs remain moist, success rates are extremely high.
