After recently reading about the use of neem oil to treat mildew and control aphids (millions of them this year!). I bought some and have used it only once. I was puzzled that I'd never seen this product in garden centres so Googled it. Imagine my surprise when I discovered that it's not approved in the UK! Has anyone used this and has any thoughts about it, good or bad.

Interesting. Yes, the aphids are amassing daily on my roses. Every day I blast them off with a water jet and every day they are back.

It is a natural product and really works to get rid of a variety of bugs. You should allow time for it to dissipate if used on an edible product. Here in the Azores, they require a permit for a lot of the 'normal' treatments, so I have switched to Neem Oil.
