Wergali seeds can be obtained as a monster drop (see below), from Managing Miscellania if your workers are assigned to Farming, from clearing a dead herb patch if a player has the Scroll of life effect on their account or bought from the Vinesweeper minigame for 3800 points each. The following table shows the profit yield, assuming all the herbs and seeds are purchased/sold at the Grand Exchange, for the guide price. If the herb dies, you will lose coins. Supercompost yields a minimum of 5 herbs.
