Stimulate plant growth in your plants and crops by supplying them with trace minerals and nutrients using RootMost Seaweed Root Growth Promoter.

RootMost is a highly concentrated liquid comprised of pure natural seaweed extracts with natural microelements that are very helpful at developing strong and healthy roots in unrooted cuttings and young plants. RootMost adds soil nutrition to help develop the root system and improve growth following transplant procedures. It is capable of providing a balanced plant nutrition to help prevent plant diseases and often reduces recovery time after transplanting.

RootMost helps plants absorb exogenous plant growth regulators, increasing their survival rate above 95% and shortening their revival time 3-7 days down before transplanting. It also improves seed germination, enlarges root zones, increases hair roots from 50% to 100%, and stimulates root elongation and thickness by natural nutrition and regulation.
