Herb runs are the ones that make money. If you're not planning to be a GF for your bank then you should also plant herbs and do them few times, and RS gold if you're too lazy, then complete them as other trees. Regular trees you CAN do two times a day, however, it's all up to you.
Here's how I used to do: 5 Fruit trees (Papaya) 5 regular tree (Maple). Regular: Lumbridge, Varrock, Gnome Stronghold, Falador, Taverly. For fruit, go to Juju Place (Buy the Juju spirit bag and head straight south. There's also a fruit area for the trees), Gnome stronghold, Catherby (theres a herb patch in the middle of the road FFS), Brimhaven (Take the boat from Ardy) and the Tree Gnome Stronghold. Supercompost all regular trees as well as pay for ALL trees. Paying farmers to remove the normal trees for you will also save time.
There are many topics on this, but what is the best method for me? I thought of breaking every melee brother so I don't need to bother with pray for them, and melee ahrim/karil. Doesn't it sound like a good idea?
I'd recommend you get 82 mage for Blitz and Karil's bow for Ahrim. Building 50+, and an apartment with a home altar and canafis portal is also a good idea. I use this setup... The 94 mage. 70 def 64 prayer, 50 cons.
I make use of prayer pots when needed (tunnels only, and you won't require them for Karil/DH because even I don't, and Ah can be tanked easily). Monks are eaten as needed. I use Barrage (you could also use the blitz) and then side-step using the sally approach for everyone except Ahrim. Blitz freezes for another 4 atts (sally/mage) Barrage lasts will last buy OSRS GP for six (sally/mage). After Ahrim I typically begin to have a shortage of the prayer point, and I just straight into tanking it for Verac, Torag and Guthan (Right before the brother gets free of frozen, I immediately switch to Guthan's pl8 or to the skirt of V).
