I have used neem oil deluted in water and with soap for several years now. But my main problem is to stop sprayer bottles from blocking. When I prepare the mixture I usually use warm water but my sprayer bottles do not last long because neem oil blocks them. Is there any solution?
Pre mix it and filter it through one of them coffee filters. Only mix enough for each use and don't leave it in the sprayer
That seems like a very good idea - I may very well copy your method if I need to use Neem oil during the summer.! Thanks!
