Currently the only way to get to the Zeah farming patch is by teleporting to the Woodcutting Guild and walking all the way around the river and back down to the south east edge just to get to the patch itself. Then when you do get to the patch there is no tool leprechaun so you can't keep the full inventory of limpwurt roots and whatever herb you may be planting. My suggestion now is to hopefully have a Zeah Patch teleport added or potentially exchanging out rock crabs for ::train with sand crabs. Larger area which would mean more spots for people to train (I understand that people don't necessarily train at rock crabs in the first place) and would also give a close enough teleport to the farming patch.
