Im growing in my own water only organic soil and I juat noticed spidermites today should I order neem cake or neem oil and can I make something with the carb meal I already have?
Neem oil is a great defense tool ...apply once the seedlings are about 3 weeks old, its systemic too to my blog: http://forum.grasscity.com/blog/1093/entry-9709-ne...
So I couldn't easily find this info on spidermites so I hope this is helpful. To get rid of spidermites a neem oil spray applied to the top and bottom of every leaf and the stem every 48-72 hours for a month or so. That's the preferred way. You can an also take 1 tablespoon pure canola oil mix with about 32oz of water and 1 or 2 drops of dish soap. Mix and spray the same as the neem. That's the I'm poor method. There's also 5 or 6 other essential oils that can be made into sprays but I'm unfamiliar with these.
