For the 65 farming and herblore requirements what can I use to boost my level. Can I just get 60 and use stew or is there some sort of limit?

Would not rely on stew since it's a 1/30 chance to get the +6. You can use mature greenman's ale for a +2 to herblore although you won't find them on the ge and it's hard to brew so just rely on the regular one for a +1. For farming, use a garden pie for a +3 boost.

You need 63 herblore and 62 farm for the boost works ;)

What would I use to boost from there?

garden pie and mature greenmans ale

So I CAN use stew if it will boost me high enough?

Yep, I believe so. Depends on what part of the quest needs it.

OK thanks, I might get 61 or 62 and try my luck :

You only need to boost to start the quest. I boosted farming and herblore using stews and immediately talked to the NPC and thanked god afterwards. I was worried when I had to plant/pick the herb as I didn't have the boost during that part of the quest and I just went on with it. To my surprise I could do it.

 

 

 

I believe I brought 3 garden pies and 6 greenman ales and a [bleep] load of stews (The colour of stew in order to boost farming and herblore is the same) and basically ate the pie and ale first then drank the stew. Once you notice that your farming and herblore is at the requirement, immediately click the npc.

 

 

 

Trust me, it works.
