The garden was abandoned and full of leaves, dry grass and debris.
Three gardeners worked for three days just to cleanup! ...and all this vegetable trash was burned on a "dirty" area of the house.
After a couple of days of hot and humid wind (the Scirocco from south est) the pomegranate trees and the oleanders was full of aphids. Damn!
I made a biological insecticide with potassium salt soap, neem oil and baking soda: I sprayed the insecticide on the trees and killed those damn aphids almost instantly!
