does anyone have a list on what you can farm and at what levels you must be to farm them? I know a bit but not sure how many you actually can so id appreciate the help :D

I only know few I'll list them:
Oran berry-lv.1 gives 1exp
weaper berry-lv.5 gives 1exp
sitrus berry lv.5 gives 25 exp
watmel berry lv.5 gives 25exp
wheat lv.15 gives 225exp
pecha berry lv.25 gives 625exp
that's all I can think about right now if I remembered more I'll edit :)

so far...

Oran Berries= Level 1
Wepear Berries= level 1
Sitrus Berries = level 5
Wheat= Level 15
Pecha Berries = level 25
Sugar Cane= Level 100
Watmel Berries= not sure on the level of this

Thank you both :) I just reached level 5 so I'm planting Sitrus berries to hurry onto wheat then pechas :D any idea how much exp sugar cane gives though?

how can you farm? i'm wondering how it is done..

After you've bought a House with at least 1 Garden Spot, you can go to "Your Home" and click on the Garden Spot.
Then choose a Berry or Item able to be Planted in the drop down menu and click "Add Item".
Finally, wait until the item is done growing and take it from the Garden.
Repeat the steps over and over.
