This is a recipe I came across yesterday because the aphids and lily beetles drove me further over the edge than usual .. I tweaked it for a quick use this morning but have a look and tailor it to your needs !
4 cloves of garlic
1 small onion
1 small jalapeno pepper
1 tsp. Murphy's oil soap
1 tsp. veggie oil
Pulverize garlic, onion and pepper in blender or take it out on them manually to release your frustrations !
Steep in a quart of warm water for 2 hours .. strain mixture dilute liquid 3 parts warm water to one part this concoction and ADD Murphy's Oil Soap at this stage .. spray several times a week if you have to .. get those little buggers !!
Powdery Mildew Solution
1 gallon warm water
3 tablespoon baking soda
1 tablespoon Murphy's soap
mix well and spray both sides of foliage every 7 to 10 days
I did a quick version of oil soap, baking soda .. a bit of veggie oil in warm water for my spritzer bottle and blasted my roses and lily plants .. I'll let you know if I screwed up with the amounts from my mad scientist routine ! ..
