You can jennyporche
But if you take care of your plants like you are doing then there will be no need for expensive neem oil?? Why do you have it or have you just bought it, before you wrote this?
If you ever chop fresh garlic then it will be left on your fingers and that will be just as good to your plants as neem oil (in tests) apparently.
I prefer test results myself.
Forgive me but I picture you cutting garlic with gloves on. Am I wrong? (or perverted)
You obviously have neem oil beforehand and it is good so use it but it is no better than Garlic (in tests) and will not help BLACK SPOT that is a systemic fungal disease similar to cancer in a way, that needs a alkaline treatment that has been tested and works on plants. (I do not mean for Cancer in humans that is still under observation and has no base in human medicine) This method is only proven to work on plants.
Its one of my favorites alkaline based cures for plants. It helps with mildew on sweet pea at this time of year and stops damping off.
Sodium bicarbonate / baking soda. (NOT baking powder!)
1 teaspoon to 1 ltr.water spray (you can try 2-1 for Black spot if you like. Please let us know the results.))
