I've recently bought some cucumber plugs and after planting them up I now notice there are dozens of tiny flies around them.
I used potting compost from last year that has been in the shed and assume this is where they've come from.
My question is, what are the flies and will they destroy my plants?
I am squashing them as I see them but there just seems to be more next time I look.
any advise would be gratefully received.
Thanks in anticipation,
