My maple tree is not looking good this year. I thought my neighbor might have hit it accidentally with Roundup over spray and wounded it and/or maybe it's suffering from some bugs or disease.
I'm not a better living through chemicals kinda guy and don't want chemical warfare in my yard, but neem oil might be exactly what I'm looking for.
Also, have you ever used AzaSol? From a web search: "AzaSol is the water soluble powder azadirachtin extracted from the Neem seed."
Now I just need to find a cheap sprayer that can shoot 20' or more to hit the upper leaves.
I feel the same way. I ordered a quart of neem oil from Amazon three years ago for $16 and I’m still using it! I’ve not tried the other stuff, but if you do tell us what you think!
