Good morning all.
This is my first year growing brugmansias and I read here somewhere that I should use neem oil for mites and aphids. I bought the concentrated bottle and have about 1/2 gallon left over. Can anyone tell me whether it goes "off" and should I just make a fresh batch each time? Just trying to be frugal :)
Neem Oil
If I remember correctly, after you make the mixture it will only be good for about a week, then you need to make a new batch. Hope that helps, Cheryl
Thanks Cheryl. I'll make a smaller batch next time.
I never knew for sure but I used it within the week, and like you I learned to make smaller amount and use it in one day,it is too expensive to waste, I also found a soap spray ready mixed in Wal-Mart that worked just as well and just $4.99 a bottle.

well I assume you're praying as you thought there was a sprayable condition.. a need to spray.. often it's best to follow up with another spray after 4-5 days.. andcatch the newly emerging.. and perhaps to catch what mighthave been missed the first time around.. being frugal and combative...I'd give everything a blast again.. before discarding it..
