The lemon tree seedlings didn't survive the transition to Sask weather except the biggest one, which was maybe 16 inches high and also got frozen in the greenhouse. However, the various branches and stem stayed green so I took off all the leaves and kept it watered...and it has come back like gangbusters but almost entirely from soil level. So now instead of a little tree it looks like some sort of hedge in the making. Should I thin any of the stems out? They are all growing pretty much straight up, no branching so far at all, the longest about 7 inches or so. It's looking really happy (the weather has turned to the upper 20sC) so I don't want to do anything to damage it.

Any way to encourage them to develop their own roots? I hate to waste any, the three main ones are already about 8 inches tall, can't determine what the situation is with the thick cluster of leaves at soil level, but everything looking lush and happy! I don't know, though, if the stems are big enough crosswise to try air layering..
"but almost entirely from soil level." UM, hate to be a downer, but was this a grafted lemon tree? if so, check that the growth is from above the original grafting.....might just be tough prickly rootstock coming away ....and ready for you to add your own graft onto this growth. ;-]

No not grafted, I grew it from seed. It froze back in the greenhouse this spring. It does have thorns on the stems though. I grew a bunch so not sure which batch this one was from, it was the only survivor. It's grown like gangbusters though, loved this 30+ C weather we've had recently. Now I just have to figure how to keep it alive over our -30C winter. Not a whole lotta light for it inside.
The lemon tree is able to resist up to -3°C without important damages.A freez at -5°C could killed the branch but he could start again at the trunk.
Its very important to simulated a winter: a temperature between 7°C and -3°C put the lemon tree in vegetal rest.
How time of light have you the winter? For the seedling of my tomato , i use a grow light and i put them toward a windows. With a programmer, you can on the light before the sunrise and during the sunset and off the light during the day.
For exemple A sum of 9h00 in december 9h30 in january 10h00 in february

Our winters here are very short days, and the outside temps can get down to -35C on a bad day. I don't know how cold it actually got in the greenhouse but the other smaller trees all gave up. Thanks for the info re temperatures that makes them dormant, every little bit of info helps.
For me the winter is influenced by the atlantic ocean and the russian anticyclone. We could have a very sweet period (up to 15°C) or a cold period (generaly-10°C up to -15°C) in february. Thr big danger is the false spring due at the atlantic perturbation.February could be a month perturbate and march could be a month antyciclonic with coldwave. but generaly our coldwcoldwave is in february.
I grow a fig tree and a persimmon and an apricot tree. Sometimes when i found a seed in the fruit, orange, lime, or lemon, i put the seed in a pot but i have not germination.
Wow , I am learning more, thank you . When the weather gets very bad in winter I bring my potted bears lime, mandarine orange and yuzu lemon in the house . THey seem to suffer more from the stale potting soil and dry and warm in the house but I was thinking outside might be too harsh . In a very bad winter we can have up to minus 20 celsius in the north winds . I am thinking however to put them out near the end of February to avoid the worst weather and in spring plant them in a south facing location that would be sheltered from the north wind and could possibly protect them with some temporary plastic panels and christmas lights next winters as was suggested by a grower here in British Columbia , Canada in a favourable climate but north of the 49th parallel. I was thinking living soil and humidity might be much better for the plant ?
