Vicki's notes for this recipe:
A Microscopic Fungus --
Black spots on roses appear mainly due to high humidity, and watering late in the day, which doesn't give the leaves a chance to dry.

Although black spots can be transferred to roses for a number of reasons, via the air, the moist conditions are a perfect storm.

Prevention is the best to deal with this.

Directions

1
Mix all ingredients in a clean bowl or bucket, mix well.

Pour desired amount in a spray bottle. In the morning or early part of day spray your rose bushes genereously. It is best to do this in the early part of spring to also prevent the early pests.
2
Another preventative for Black Spots on Roses is "Milk".

Put in a spray bottle, and spray leaves top and bottom - in morning or early part of day.
3
Dormant oils stick to the insects and suffocate them by clogging the pores they breathe through.

Petroleum Based -
Most dormant oils that are commercially sold are refined from petroleum oil and have an emulsifier so they can mix with water. These are known as mineral oils.

WHY DORMAN OIL?
The oils work best when the insects are just emerging from their dormancy period early in the spring.


Dormant oil is a liquid substance that is sprayed onto trees when they have no leaves, thus the term dormant. It acts as a fungicide and pest control agent to prevent damage to the buds that will open in the spring.
4
SPRAY WHEN OUTSIDE TEMPERATURE IS ABOVE 50 deg. for a couple of days.

Pour 1 cup of vegetable oil into the garden sprayer, followed by 2 tbsp. of liquid dish soap.

Add 1 gallon of warm water to the sprayer tank or bottle. Shake well and saturate trees, exposed bark, branches - before budding in the spring.

I'm happy to help, Millie. The timing of this is important. That fungus on the roses are terrible! Just remember Not to water the bushes late in the day.

I'll be posting other things tonight.

I look foward to seeing your other posts.
We try to never water in the evening. I'm hoping to get some soaker hoses in the beds this year. Not a big fan of over head watering either.
