Answer: Citrus trees love warmth so I'd move them out of freezing temperatures as soon as possible. Start by moving them into an unheated basement or garage for a few days, then gradually expose them to indoor temperatures. If you move them directly into a heated house from outdoors, they will go into more shock than they're already experiencing. Once you've got them indoors, place them in a bright, sunny location. Expect the damaged leaves to drop and the plant to look forelorn until it adjusts to its new growing environment. It should adjust with time and begin to produce new foliage. Best wishes with your project!
