I don't wear a lot of make up, so when a friend of my then boyfriend bought me a make up brush set, I used the brushes for cleaning the dust off my cacti and fertilising the flowers. I recently found them again (they were at my folks' house where my cacti live) and brought them back to Wales for use in the greenhouse. Handy for brushing soil off leaves after repotting plants, etc. Was there somewhere a comment that plants are happier if their leaves are brushed?
