I just read that marigold flowers are a mosquito deterrent.
I've just been attacked in my garden by tiny mosquitos and am now determined to get rid of these pests. My backyard pool is nearby this garden so it is a 'mozzy haven'. At the top end of the pool is another garden with marigold flowers (terribly handy in this situation of mine).
I now plan to transplant some of the marigold to the bottom end of the pool in the garden where the mozzy's are feasting away. I'm not sure if this is going to work or if the marigold will survive the migration but i'm going to try.
Keep you posted.
