>>803744Weird... you seem to be in a much more tropical climate than I am (I'm 50°N) and my lemon seedlings (sprouted in mid-July last year) over wintered just fine (had them inside from mid-October to late April, with gradually increasing outside periods on warm days to get them used to the sun again starting in early February)
We get very little sunshine here over winter (sunrise/sunset 8:20/16:30 in mid-December) so I put them on the south-facing window in the kitchen (temps there being around 17°C that time of the year) and they did just fine, with slow but consistent growth
As of now they're growing more quickly again, btw we have a very similar looking garden table (IIRC ours was bought back in 1999)
