Head over to Oasis, which is easier said than done.  It's all the way up north, somewhere around the middle of the latitude.  You'll have to follow the highway tracks until you get to a valley-like landscape.  Look around for a small path between the rocks, which should be a block away from a large road on your map, a block on the right that is.  How vague can I be?  This vague, apparently.  It's best to use a map for this.

Once you've found the place you're quickly hailed as a savior - although you don't really know what's going on at all.  Hear their story and follow Tree Father Birch inside after agreeing to help.  Proceed the story by continuing the conversation until it becomes clear you must undergo a ritual first.  Drink the Sap from the Basin of Purification and you can continue.

In the next area, find the talking tree (a little too much Oblivion inspiration here so it seems..) and hear him out.  He wants you to kill him, we'll have to see about that.  Return to Oasis and find Tree Father Birch and his wife to the south.  Overhear their conversation, then get an additional two optional objectives.  You'll now have three choices.  First of all, get the key from Branchtender Cypress, who should be nearby.

Now you can enter the cavern on the west.  Prepare for a cavern full of Mirelurk enemies - you may even encounter a Mirelurk King if your level is high enough.  Make your way through the extremely straightforward tunnels until you get to a pool. Dive in and go through the southern tunnel.  Emerge and make your way through another straightforward cave tunnel until you reach a door that leads to the Cavern Tunnels.

Head west at the intersection to find a pile of rubbish.  Inspect the trash to find a [STEALTH BOY], [CHERRY BOMB x2], [10MM ROUND x2], [DARTS x20], plus a bed for resting.  Make your way through the cavern until you get to a small pool.  Destroy the Mirelurk and dive in the pool.  You can find a [MINI NUKE] underwater.

In the next cave, curve around the center and find a skeleton on the north among his supplies: [BLOOD PACK], [RADAWAY], [MISSILE], [PURIFIED WATER], [STIMPAK].  Waste the two Mirelurks in this room, then proceed to the southern area and find your mission's objective: Harold's Heart.  You now have three choices:

1. Destroy Harold's Heart.
2. Apply Birch's Sap to stop his growth.
3. Apply Laurel's Liniment to accelerate the growth.

The best reward lies in destroying the heart, for it will grant you the Barkskin Perk that adds an instant 5 DR.  The other two will grant you a unique outfit, but more about this in a minute.

Head south and find the door to the Damp Cave.  Follow the straight path and drop down in a large cave with two Mirelurk Kings and a Mirelurk.  Waste them and check the skeleton on the right (east) to find an [AMMO BOX], [STIMPAK], [MED-X], [RADAWAY] and a [SNIPER RIFLE] (I guess it didn't help him).  Dive in the water and swim through the underground tunnel on the NW to reach the Grove.  Find Tree Father Birch near the former Harold. Speak with him and the quest will end.

Note: If you had chosen Birch's option you will be rewarded with a Missile Launcher and Missiles, plus the unique Druid's Outfit.  If you instead would have chosen to help his wife Laurel, you'll be rewarded with a Brotherhood Outcast Power Armor and a Villager Hood.  The Armor gives 10 Rad Resist, 5 Big Guns, 1 STR, -1 AGL.  Overall it's not better than Ranger Armor.
