I sprayed Neem last year and it kinda had a browning effect on my trees! Very undesirable, I wanna avoid that like the plague this year, the directions say to mix 2-4 tbs per gallon, I wanna make it as strong as possible without any ill effects, what do you guys suggest?
Thanks

Most oil products will cause leaves SUN burn depending on sun power, I might be wrong, If you mix it stronger, After spray leaves, Do not put trees under sun for few day.

I am loser for Fig bud mites, Canada ban all long lasting pesticides, I can not win,  I am waiting for mild outdoor cold winter here with agricultural lime to clear them at the winter time.

I use 2 tablespoons of neem per gallon of water in a small sprayer for white flies, mites, etc. I only spray at dusk causing no damage with good results. If you spray during the day the neem will cause sunburn on most fig trees.
Good luck

Yes,spray in the evening.

This is another problem, During this time of year, Most fig trees are in strong vegetable growing with lots of Young / thin leaves, I sprayed my newly arrives mail order fig trees with pesticide due to fig bud mites found, After 5 weeks, It droped all leaves, not sure other people can give your good advice on this one.

I use Neem oil all the time on my plants. What I learned spray in the evening and WATER WELL before spraying.
I did learned this after burning some of my plants leaves.
