    Curious who has used neem oil for spider mites and such, and im going to try and create a format to keep this organized.

    first - what percentage (70, 80, 100%) and brand of neem oil did you use?

    second - how much did you mix per how much water?

    third- how often did you spray it on your plants, or did you dip them in it?

    fourth- did it harm your leaves/plants?

    fifth- any other tips or secrets?


    thanks everyone

    The label has how much you use. Mine used 20ml per Litre. Spray them twice within a week and make sure you spray the WHOLE plant. Under the leaves, EVERWHERE because you have to kill the eggs too. To prevent them ( or help kill them now) you should do a combination of lowering your temperature and increasing your humidity. Both of these make it harder for mites to live

    :bigjoint:I have had some problems with whiteflies in my garden-I tried a spraycan of pyrethrin-no help. I tried Safer insecticidal soap-little help. I then bought a little jug of neem oil,made by DynaGro. Followed the directions at 1 1/2 teaspoons per quart(6 tsp. per gallon)- next day,I had so many leaves burnt looking and falling off that I thought I might have ruined all my girls-funny thing,only the lower and inner leaves were affected-all the top and outer leaves looked fine-and only one type(snowbud) was affected-the others-G13 and Mango-were totally unaffected-STRANGE! After a few days,all plants looked good-but whiteflies were back at it again. So this time,I cut back to 4 tsp. per gallon-and made it a gallon of Safer Soap-made it from concentrate-this time,no leaves were affected,and the whiteflies seem to be pretty much gone-though today I did see a few,so will spray again tonight-I do think this mix will take care of business. Also,you should spray when your lights are off-I do it when the lights just go out-so they have 12 hours of no intense light,which will help keep the leaves from burning.
    I hope this helps you out brother....:bigjoint:
