Plant seeds in farming patches (herbs, trees, fruit trees and vegetables) at different locations, wait for them to grow in real time, then harvest for crops and Farming XP. Higher Farming levels unlock better seeds. Vegetable patches (Potato at level 1, Sweetcorn at level 9) yield 1-50 crops per harvest — a higher Farming level just weighs the roll toward a bigger harvest, it never guarantees one. Harvest everything at once with Harvest All. Magic Secateurs — the untradeable Lithe Farm reward — double the crop from every herb patch while wielded; they carry no combat stats. Seeds and saplings come from the General Store (basics), the Trading Post, and slayer monsters — the higher a monster's Slayer requirement, the better the seeds it drops; Potato and Sweetcorn seeds are common early drops from low-combat monsters and the Master Farmer. Every herb a potion needs is farmable, from Greenthorn at level 1 up to Thornspire at 94 — the higher the Herblore level of the potion it goes into, the higher the Farming level to plant it. Pickpocketing the Master Farmer rewards one seed per steal from that whole ladder, and the higher a seed's level the rarer it is: Greenthorn and Potato seeds pour in, a Thornspire seed is roughly one steal in a thousand.
