your welcome VT
Advice from the Citrus Centre where i got mine was spring to autumn feed citrus food each time you feed, and stop during winter, i put mine in a wood cabin about two feet from a window throughout the winter, they don't like frost. During the summer it lives on the patio,
Last year due to the weather it doubled in height.
When harvesting take the leaf stem, cutting back will stimulate growth, their is a stack of stuff on youtube.
good luck
