How do you get your farming level up?

Farming takes awhile to get up because you have to plant crops which take a long time to grow. A good way to start of farming is to do some quests which give farming reward or use experience lamps on farming, then after your level is quite high grow the more experienced crops/trees which give alot more xp. When you grow something you have to water it every few minutes and check if it is diseased or not. Check out Http://www.tip.it/runescape Click on the skill guides and quest guides. This should give you a much better understanding as the skill guides are very good :)
