I have a very large (male) Yew Tree alongside and quite close to my
greenhouse, shed and garden. *Parts of the tree, pollen, leaves etc blow
onto the roof of the shed and greenhouse and stay there for some time
until I clean them off. *

I would like to collect rain water from the roof of the shed and
greenhouse to water the vegetable plants both in the garden and
greenhouse. *The question is, is it safe to use the water that has yew
pollen and leaves have soaked in ??

The vast majority of leaves are dead and brown with only occasional
green leaves being on the roof

Many thanks ...............

I had a garden once surrounded with yew trees. I never noticed any
problems with the fallen needles.
