As long as it's been outside for a few days to acclimatise again, I'd just plant it. They don't need anything special, just prepare the ground it's going into with some decent compost, a bit of general fertiliser like Blood, Fish and Bone, and water in well. A mulch of bark or some manure will also help to retain moisture. You only need to water if there's a long dry spell until it's established. It will then look after itself unless planted in an unsuitable location.
I'm assuming the soil you have is in reasonable condition, and isn't either waterlogged or sandy. If the ground's poor, the compost will give it some nourishment, and adding some well rotted manure is also useful whether the soil's heavy or very light.
