Q: I have a Meyer lemon and a Key lime tree in a three gallon pot. They’re about two feet tall. I intended on separating them into different containers but they have started blooming. Should I go ahead and separate the two plants so they have more room to grow? 

A: I think the plants would be happier if you went ahead and separated them now. Give each one an 18″ wide pot in which to grow. When you bring them indoors give them as much supplemental lighting as you can afford. I put three 100 watt CFL bulbs on my Meyer lemon during the winter months. Remember that the fluorescent bulbs need to be no more than 12 inches away from the foliage.
