neem oil shelf life
Hi all. I'm going to try neem oil for the first time this year. I read the sticky, which has lots of good info. I'm thinking of ordering a 32 oz bottle of dyna-gro, but I was wondering if it has an expiration date, or if it would weaken over time. Tks.

I have no memory of WHEN I purchased my Rose Defense. I know that it was after we moved to this house (which was in July 1997). So that's an early bound. I know that it was before April 2007, when I had knee-replacement surgery. So that's a late bound.
And it still works very well. As of this month, then, the Rose Defense (neem oil/azadirachtin active ingredient) is somewhere between 3.25 and 13 years old.
It lives outdoors, on a 4-foot-high "potting table," in a carport.

Vergil is sleeping very soundly, and has been for the past 2 or so hours, since we came home from being outdoors all day. We left the house at 0645--very early for him at any time, esp. post-op--and his extended sleep has allowed me my first extended visit to the forum since before his surgery on May 26.
