Similar to other berry bushes, lergberries may be individually picked, without waiting for a full harvest, and they are also renewable, i.e. if the patch is not cleared, more berries will appear after growth. 3 lergberries are the payment demanded by the zombie farmer for tending kalferberry bushes, and 5 lergberries will convince him to tend your shengo herb plant.
