Making your own horticultural oil
I found these two recipes for making your own pest horti spray and wondered if I could successfully use the first one (Generic oil spray) on a small scale problem??? I already have veg oil in the house that the first recipe requires.
I went to Lowe's today to buy some h. oil but they didn't have any at all.
I was recently given a bunch of spider babies that I planted in a hanging basket. a few weeks later I noticed some of the leaves looked funny, some were folded in the middle like you would fold a piece of paper in ha;f, that's when I discovered a few scale. I would normally toss anything with scale, but, this one time I wanted to see if I can't get rid of them.
Here are the two recipes....
Generic oil spray
1 cup vegetable oil
1 tablespoon dishwashing liquid
Mix 1 tablespoon with 2 cups of water. Fill a spray bottle and shake well.
Pest and Foliar disease oil spray
1 tablespoon baking soda
2 tablespoons ultra fine canola oil
1 gallon of water
Combine all ingredients and shake well. Use on plants to combat fungal diseases.
Will the oil dry on the plant in a week, then I would need to repeat treatment right?
