Guam seed

Guam seeds can be planted in a herb patch in order to produce grimy guams. This requires a Farming level of 9.

A nearby gardener will not watch over your growing guam.

Guam seeds may be bought from the Vinesweeper minigame for 10 points each, by pickpocketing Farmers and Master Farmers, as a drop from various monsters, and from Managing Miscellania.

When planting a Guam seed, it is recommended to use any type of compost in order to maximise potential yield and to reduce the chances of the patch becoming diseased and dying.

Farming

1. ^ Applied on Wilderness herb patch only.

When farming, there is a chance to save a harvest when using Magic secateurs, yielding more produce. This can be calculated as ${\displaystyle SaveLifeChance={\Big \lfloor }{\big \lfloor }0.56\times }$${\displaystyle +24.44{\big \rceil }\times (1+}$${\displaystyle ){\Big \rfloor }\div 255}$. Yield can be further improved by using boosts such as compost and the greenfingers aura.

Profit
