Today I noticed my Rose plant is infested by scales. The whole branch is covered now.. Not sure how I missed to check this.. Anyway I have been told that this can be easily fixed by applying soap and oil concoction.. So I made one by myself. The details about the recipe is as below.
For smaller batch
1 tablespoon or 15ml dishwashing liquid
1/4th cup/60 ml vegetable oil
mix this well
and add 1 part concoction with 20 part water and spray..
This will suffocate the scales and kill it..
Try to do this after sunset...
