I live in Buffalo, NY (snow anyone?) and last summer started with a 2-3 year old Meyer Lemon from Four Winds Growers. It was potted, left outside for the summer, brought inside this winter (our house was kept at 66 when we were home and awake and 58 when we were away or asleep). It had a few flower blooms over the winter and in the spring just before we took it outside again, 2 lemons started growing. Haven't picked them yet, but there are now 6 full size lemons (still green though), and at least 10 smaller ones starting to grow. No insect problems to speak of...yet...Very easy to take care of. If the leaves start yellowing a little, we give it some fertilizer for acid-lovers, and they perk right up again. Very excited for some lemons...
