We had a very successful crop of limes last fall - about 250 limes, from which we squeezed about a litre and a half of juice. As recommended by Will B. in a post last year, we froze most of the juice in ice cube trays and have used it for mixed drinks (G and T, Daquiris, Margaritas, etc.) over the fall and winter months. We did have a scare last winter though. The tree is in the ground, so it has to be protected over the winter. The risk is that we have a power failure during a cold snap and lose use of the electric heater. (When it gets below about -7 C the 7 watt Christmas lights that we rely on to keep the tree a few degrees above freezing need to be augmented. The back-up heat is from an electric heater with a thermostat that kicks in and out.) During the third of our three deep freezes last winter, when the ambient temperature was about -13 C we had a 5 1/2 hour power failure and the tree suffered some damage with several of the branches dying from frost bite. I'm happy to say that it has survived and there is lots of new growth following the recent warm spell.
