Go to Bob!

Buy seeds, starting off with very first ones.

Teleport to Farming spot from skilling teleports. Plant a seed to Tree patch.

After that pick herbs by simply clicking patch.

Clean herb by clicking on them in inventory.

Go buy vial of water from bob and use it on cleaned herb!

Get ur seeds, plant n' pick em. Just don't bring water there, you can do it later. Use all ur seeds and then start herbloring. Thats it
