I live by the professional courtesy rule myself, both my self and my brother worked for other landscapers prior to stating our own business, Neither of them tried to discourage us growing and doing our own thing. I believe if you have professional courtesy and don't step on each others toes it is fine. If someone calls me to bid a property and it happens to be a close friend of mines property i will decline kindly and say sorry i'm not interested, and vice versa.
There is plenty of work for everyone and no need to try and discourage/sign a non compete. That's just plain stupid.
