I am thinking of ordering a quantity of Trichoderma granules for mixing into compost etc. There will be too much for me to use (or to afford!). Anybody interested in a share?

Anne, what sort of quantity/money are you expecting to share?
-
I'm thinking of ordering 5kg of granules for mixing into compost, and maybe 500g of powder for watering on as well.
The powder is used at a rate of 3g (about a level teaspoon) in 10L of water for first application, then at half strength thereafter. These quantities are £65+vat each. If anyone can get it without paying vat please let us know!
The granules are used at 750g per cu m in compost (or a pinch a pot!).
Here is an interesting article someone told me about last year:

PS Lesley said the granules have to be incorporated into the growing medium and not just sprinkled on the surface.

Yes, that's what the literature always says, I suppose because there's nothing on the surface for the fungus to start work on. It needs moist humus to work.
It works a treat on any clematis I've planted in recent years. Haven't lost one to wilt as previously. I just dig about a tbspful into the planting hole.
