Go to the farm field and click on a pile of loosely turned earth to plant a seed. Now click on the Water Jug in your inventory to water the seed. Do this to five piles of earth. By this time you can return to the first and right-click on the mature plant to harvest the Albidis Plant. Repeat until all five are harvested.
The game has changed, slightly. It used to be, you could plant and water all 5, then go back to #1 and harvest them all. Now there are Shadow Rabbits that will appear from nowhere and eat your sprouts if you do not defend them! All you have to do is right-click the rabbit to kill it.
