Ranarr seeds can be obtained as a monster drop, by pickpocketing Master Farmers, from Managing Miscellania if your workers are assigned to Farming, looting nature implings, cleaning out a bird's nest, as a gamble reward from the Barbarian Assault minigame or bought from Vinesweeper for 4000 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. Note: Supercompost yields a minimum of 5 herbs.
