I am new to this gardening thing and need some help as to what to do!
I was wondering if there is any gardening solution to pest control
without using pesticides, the kind of pests I am interested in
controlling a whitefly, greenfly etc...


It is quite satisfying to run the fly infested stalks and leaves between
your thumb and finger. Sounds sadistic but it works. Other than that,
I find diluted washing up liquid reasonably useful.
