Expert Gardener Neem Oil Insect and Disease Control, 12 fl oz. Concentrate

Great concentrate to refill my 16 oz neem spray bottle. 1/2 tbsp for 16 oz, up to 2 tbsp a gallon. I've tried so many products. This is the only one that really works. I try to spray once a week if there's an issue and spray or water with the diluted mix once a month for upkeep. Gets rid of all the little pests on the plants and even the gnats that like the damp soil. It doesn't smell good but the smell doesn't last long. Important- Spray at the end of the day or keep the plant out of the lights/sun that day as it can burn the leaves when sprayed on them then exposed to light for too long.

I started having a horrible time with aphids, black spot, white dusty powder on my flowers, my hydrangeas, my hibiscus I felt I was going to have to dig them up. This is my 2nd purchase of Expert Gardner. I don't know what the difference is between this Neem oil and the 2 other manufacturers but it is starting to clear up on my roses. If my hibiscus snap out of it then I will say this is the gold. I will update with I pictures when my flowers are back to normal.
