Rumncoke,

Pull the soil off of the base of the tree - even though it is in a pot, it may be too deep. Clear the soil away until you can see the root flare - or the trunk flare - that part is supposed to be exposed, but lots of nurseries add extra dirt to pots before they sell plants. You'll be surprised how much that one move can make a tree happier.

We have a chance of showers for a few days (it hasn't rained much this month) and supposedly winter temperatures will return next week, but the forecast doesn't show any nights at or below freezing and highs in the 60s aren't typical February temperatures.
