Hmm.
It may be that some people don't realise that the ownership of the house has changed and if they do, some don't appreciate that you might not have either the propagation ability, or, have the time and interest to want to carry on the tradition.
It was very convenient for many in the past to have this no doubt "free" facility, but you are in no way obligated to continue it.
Don't make a rod for your own back.
It might prevent any confrontation if you put up a notice by your gate to the effect that you are a new owner and regret that you do not have the skill or the time to continue with this previous practice.
If you do something for one, it'll get around and everyone will want something.
