As far as I know you cant pick grapes there are no such thing
Well, as far as i know grapes are not produced on runescape, you can get them from these four places: you can buy them in the grand exchange, you can kill goblins and pick them up, you can kill guards and pick them up, or you can go to the cooking guild and pick then up from the spawn on the top floor
Buy them on the Grand Exchange. Another option is to kill guards around Varrock - they drop grapes.
Put Grapes In A Jug Of Water For Ten Mins.
They pick it at random.
After they have frozen.
pick the berries!
Out side the cook's guild or everywhere around runescape except the wilderness part.
you can pick flax at lletya, gnome stronghold, or catherby flax field.
pick pocket ham people.
You don't. You plant them and grow them and finally pick them.
Go to the Grand Exchange and buy them.. i think they also might be in the cooking guild EAt them and you will poo them out!
If your combat level 25+ then I would recommend that u go to varrok and fight guards tht a level 21 and they wil drop 3 grapes every once in a while.
