Q.watering mexican lime tree
just i got a mexican lime tree that nobady was taking care,
most of the leaves are falling, i started to watering inmediatly.
my question is: its gonna survive? it was a christmas gift.

If this is in container, and indoors... then this is common. Even in the brightest window in a house, there will not be enough to keep it happy. There are a few things you should keep handy. Dolomitic lime, iron sulfate, and citrus fertilizer. These should be applied once or twice per year. A 200 watt horticultural fixture will be enough light for a small tree.
