The Eil and Tasmanian Institute of Agricultural Research has been researching the use of hemp straw as a mulch for use in orchards.

Both the bast and the hurd are highly absorbent and good insulators and make excellent mulching material. Trials on apple trees in Tasmania have shown that the hemp mulch compared well with other mulches, both in terms of soil fauna and in fruit quality. It is also thought that a hemp mulch could be useful for stabilising sand dunes that are liable to erosion.

Madsativia was correct :thumbsup:. However I would still have to agree with Bedrockbob if there was a problem in the prior crop.
personified Reviewed by personified on . MJ Mulch What do you think? If you took the stems and leaves (if not used or left overs from making hash) then ground them down add some water with a little fertilizer as a binder then compress into plugs or squares. It seems that this part of the plant could be both good for retaining water and act like a fertilizer or just a good over all mulch. In my mind there is energy in the stems. Give me your thoughts or experiences if you have tried it. Rating: 5
