Answered Farming

pretty much what Zep said, I used to log in and do my tree run and then my herb run, I'd also bind my amulet of nature to my last herb patch so when that last herb patch was ready all the rest would be also.

my route has always been:

Trollheim, Ectophile, Falador (cabbage tele), Ardy, Camelot.

back when I was farming seeds weren't anywhere near as expensive as they are now and I'd grow the highest lvl herb I could for my lvl, if I were you i'd farm whatever seeds you can for your budget.
