I don't know if there is already a thread about this, but I"m sure that someone will tell me if there is, I am, atm having awfull problems with mites on my trees, mainly the plums, but all trees are effected to some degree (even the large fruit trees) and In my research I came across a number of natural remedies, so I thought, why not start a thread, listing recipes, and warnings (ie, don't spray white oil in the middle of the day on a 35degree day) don't spray surface spray directly onto a tree etc.....
I will go first, I made up a white oil mix out of cheep vegetable oil, dishwashing detergent and boiled up garlic, 1 cup oil, 2/3 cup detergent, and prob 3 cups water of garlic water, threw this in a 6 litre spray bottle, topped up with water, and sprayed everything in sight (minus dogs and kids) nothing is dead yet, including the mites I guess... lol
However,

it will work....
Any other suggestions??
