we bought three lemon trees when we moved in to this house. Same size as your lime tree. 2 years later:I'd say it's at least 8" taller. Can't wait for limes...
That’s one, two behind it are 25% the size - going to move them to a sunnier place Hoping maybe a harvest early next year? In HK we got a single lemon in years. (Got a single pineapple too) no one grows lemons here - limes are ubiquitous because cooking (they call limes lemons as well which gets really annoying)
I keep meaning to transplant a lime cutting on to it - long way out but have you thought of doing that? Frankenlimon
