Kalferberry bush

A Kalferberry bush is a Herblore Habitat farming resource, needing 77 farming to plant it. It can attract certain kinds of Jadinkos while it's growing or when it matures. After growing into its full size, you can pick Kalferberries. To prevent the chance of disease, the Zombie farmer can be paid three lergberriess to take care of it.

It can get diseased as well, having the need to use a pair of secateurs to cure it, however, pruning it with Magic secateurs will turn it into a Kalferberry bush, making you gather Kalferberries.
