never stay in 1 place to farm, and never watch your crops either. Where possible, get the farmer to look after one of the allotments on each patch, that way you will guantee get at least 1 patch's xp. Move onto to trees when you get the level, and again, let your farmer, not you, watch the crops. you will get the farming for rannarrs in no time. (though you will lose some to disease. however if you use super compost, it will reduce the chance drastically)
