Not just for health
I use neem oil for my garden. It is a great insect repellent, cat and bird deterrent and soil conditioner. Undiluted and dripped around the area where cats are littering or blackbirds digging up the soil immediately puts a stop to their activities. This neem oil is thick and value for money (unlike hardware store variety) so rain won't wash it away and the natural smell and bitter taste stops unwanted pests from destroying my garden. Highly recommend it for garden use. I have also diluted it and used it as a spray for the plants too.
