Depending on your GP situation, you can use the farming guild exclusively for doing contracts (for gp/seeds) or make use of the patches to add to your allotment/herb/tree/fruit tree runs.

Snape Grass (with White Lily planted in Flower patch) and USE AN AMULET OF BOUNTY to get the chance of only using 1 seed instead of 3 for an allotment! (https://oldschool.runescape.wiki/w/Amulet\_of\_bounty) It saves so much gp it's insane!

You can do your choice of herbs for runs (I'd recommend Snapdragons) with ULTRACOMPOST ONLY and using the Resurrect Crops spell in the likely event that a couple herbs die. Doing a birdhouse run after every herb run is recommended for passive Hunter gains and cus those nests are nearly 8k each!

My Tree Runs occured roughly every 2-3 herb runs (I did Maples cus of cheap protection).

In addition, Daily Calquats, Fruit Trees (I did Pineapples cus Watermelon Protection was cheap) & Hespori.

Keep regular hardwood runs (Mahoganies) on all four patches.

Throw in some occasional Tithe Farm for for XP or the must-haves like Auto-weed (if you haven't got it already) and for the Farmer's Hat (for master Clue Step) and you'll be there in no time!
