[edit] Beginning the Quest

Asking the gardeners.

Fairy Nuff and the Queen.

Zandar Horfyre.

Digging for the skull.
Talk to Martin the Master Gardener (you must not have pickpocketed him recently or he won't talk to you). He's walking around the pig pen north-west of the bank in Draynor Village. He'll mention that his Mister Lincoln roses haven't been doing as well as they used to, and he suspects something's wrong. He wants you to ask the other members of G.A.G. (Group of Advanced Gardeners) if they're having the same problems he's having.
[edit] Gathering Info
You can choose any of the gardeners near the farming patches (allotments, hops, trees or fruit trees—anywhere you could pay a farmer to watch your crops) around RuneScape. You need to talk to 5 of them. Ask if they are a member of the Group of Advanced Gardners.
The easiest ones to reach are the those north of Catherby; next to the bar in Port Sarim; south-east of Falador; north-east of Lumbridge and behind Lumbridge Castle; if you have no weapons or armour then off to Entrana to Francis; and if you've done Ghosts Ahoy, teleport by Ectophial and go west to Lyra. There is also a patch over near Rimmington.
All of them say the same thing: They've been having trouble with poor crops. They all have different explanations of what's wrong, though. However, the last person you ask will have a more interesting explanation. He or she will suggest maybe the fairies have something to do with it. While it does seem to be a bit fantastical, that would only be if it weren't for the fact that you know a few of them.
Go back to Draynor, and talk to Martin again. After telling him about the different ideas, go check up on the one you have the most control over. Get your Dramen Staff or Lunar Staff and head south-east to Zanaris.
[edit] Trouble in Zanaris
Head to the Fairy Queen's chamber. It's just south of where you enter the city, in the room with the Slayer master. However, something's wrong. The queen herself is missing, and instead, someone called the Fairy Godfather is here instead. He'll tell you that the queen has fallen to some sort of illness. She's under the care of Fairy Nuff. To find the queen, head west and go to the room to the north just past the windmill.
Talk to Fairy Nuff, and she'll tell you the details of the queen's illness and give you a symptoms list to take to a wizard named Zandar Horfyre.
[edit] Investigating the Illness
Walk or teleport to Falador, and from there head west and enter the Dark Wizards' Tower. Head up to the top floor, and talk to Zandar. He'll take the symptom list and then suggest you talk to Malignius Mortifer.
He can be found east of the Crafting Guild and directly south of Falador, along with four elemental wizards. Talk to him, and he'll tell you he could probably help but wants something from you first. He wants a skull from a grave near Draynor manor.
Go to the manor and around to the back (north side). Dig up the grave there. If you need a spade, there's one that respawns in the manor.
[edit] Magic Secateurs
Once you have the skull, go back to Malignius and give it to him. He'll tell you that the queen's problem has to do with a creature called a Tanglefoot. To kill it, you need to enchant a pair of secateurs to turn them into magic secateurs. To do this, Malignius will tell you to get three or four items. These are different for everyone, so you cannot just get any combination of the following items. You must get the items assigned to you.
The requested items may include items from the list below. Warning: Ghasts in Mortmyre swamp will eat any foodstuff you carry. If one of the required items is edible, there is a risk that you may lose it.

Beware! Items of food will rot as you make your way through the swamp. It is advised to bring more than 1 of your desired consumables.
When you are finally ready, grab the 3 items Malignius told you to get, your Amulet of Ghostspeak, Druid pouches, and secateurs, and go to the Mort Myre Swamp. Walk uthso until you find the Grotto Tree, and talk to the Nature Spirit. He'll bless your secateurs, at which point they'll take on a green glow.
[edit] Killing the Tanglefoot

Tanglefoot
Head back to Zanaris. Bring your armour and food. Head south-east from the bank to the mysterious ruins of the Cosmic altar. (You can take a shortcut if your Agility is 46, and a better one if it's 66.) At one side of the room is an opening you can climb through. The Gatekeeper there will try to stop you, but when you tell him what you're up to, he'll let you through.
Inside will be a bunch of Baby tanglefoots, and at the end of the tunnel will be a large level 111 Tanglefoot, in a chamber. Approach it. Note: if you have Protect from Melee, this is an excellent time to use it.
Wield your magic secateurs to kill it. Make sure you are wielding them or you will not attack! Grab the Queen's secateurs that the tanglefoot drops.
Head back to the Fairy Godfather, and give them to him to finish the quest.
