Willow tea etc

[Anthony Nelson-Smith]

I, too, would be glad to know about willow tea.  I have a big old Black Hamburg vine, in a long lean-to glasshouse, which has suffered from intractable mould/mildew over the last couple of years.  I grow nettles and mares-tails without effort (!) and also have numerous pussy-willow trees (Salix caprea), valuable as an early source of pollen for my bees - any use as an anti-fungal tea ?                 Tony N-S.
