Zwann's Watering Can (Magic Can)

Invented by the noted botanist Salerno Zwann, this otherwise ordinary watering can is activated when the user fills it with two gallons of water and lets it stand undisturbed for 30 days. At the end of that period, the user may sprinkle the water from Zwann's watering can over a patch of tilled soil no larger than a 25-foot square. Seeds subsequently planted in this treated soil grow normally, but are permanently immune to disease, drought (the plants never need to be watered again), insects, bad weather (such as hailstorms and early frost) and all other forms of nonmagical trauma. The plants can be harvested normally by the planter.
Water from Zwann's watering can has no effect on already maturing plants. It cannot revive withered, diseased, or insect-infested plants.
The patch of soil retains its effectiveness for one year, after which time it must be watered again for the effect to be renewed.
