We have found that the best way to avoid problems is to communicate very clearly with the farms you intend to visit.
Always telephone or e mail before visiting a farm. Please never just turn up unexpectedly on a host’s doorstep expecting to be made welcome.
Try to plan your movements well in advance and keep hosts informed of changes in your plans.

Make sure that you have a clear agreement with your host as to the basis of your stay (e.g. hours, food, accommodation, facilities, arrangements if you take children with you etc.) before you arrive. Tell them about yourself and what you expect. The farm owner should give you plenty of information about what is happening on the farm at the time you intend to visit, how long the hours will be, what needs doing, what the accommodation is like, what there is to do in your free time, places to visit etc.
Make sure you have a valid address for the farm you intend to visit.
Always take suitable clothes i.e. gloves and good shoes or boots. It may be necessary to take a sleeping bag.
It would be a good idea to make sure you and your host have a language in common!
Always have a copy of your WWOOF Italia membership card with you as hosts will wish to see it.
