How can we best look after the tree, particularly in terms of any
watering? The man at the shop where we bought it was very blase about
what we did with it and wasn't much help.

Keep the tree as cool as possible (within the limitations of having it
in the house) and WATER it. The redcommendation is at least one pint a
day, but with a tree as large as the one you have, I'd go for two pints
a day. Invest in a good size, deep, tray/saucer thing (sorry technical
term has escaped me....) to put under the pot to catch the excess water.
