Vitax Q4 Rootmore is packed full of beneficial organisms and biostimulants to boost root growth and create healthier plants. Mycorrhizal fungi form a symbiotic relationship with plants. They live in and on the roots, extend their hyphae into the soil and make phosphate, nitrogen, other nutrients and water available to the host plant. They extend the effective root area many hundred times, so plants establish and grow faster, larger and stronger with less fertiliser and water. This results in reduced losses during transplanting and establishment, improved draught tolerance, reduced need for fertiliser and stronger and more resilient plants. This product contains a range of endomycorrhizal and ectomycorrhizal fungi, seaweed and other humates in a natural carrier. Directions for use: when transplanting from the container, pot or open soil, sprinkle Q4 Rootmore evenly into the bottom of the planting hole, so the plant sits directly in contact with the plant's roots. It isn't necessary to add Q4 Root more to backfill when planting.
