I've continued with sowing more saxes this winter and now have a number of pots of different species coming along quite well. What would be the next step? At present I believe they are too small to do much with other than let them grow onto a bigger size. I'm assuming that each little seedling will grow into a small plant and eventually a larger plant after some years. Should I: a) grow them on for a year and then try to prick them out into individual pots; b) just repot them in the fall into a slightly larger pot and then wait another year before pricking them out; c) let them grow in the same pot for another year and then cut the soil into quarters and plant each quarter into a separate pot; d) do something else?
I've been fertilizing them with half-strength liquid fertilizer 10-15-10 each time I water, but comments I've read on the Forum indicate that I shouldn't fertilize too often. What I'm trying to do by fertilizing them is to get them to develop a bit quicker than they normally might if left in a poor soil. I plan to grow these saxes outside in my garden where they will have to acclimatize to our cold winters here in Eastern Ontario - although normally we get enough snow to protect them from the coldest temperatures and drying winds. I've included a photo of Saxifraga canaliculata that has germinated so far. Presently, I have them growing in my unheated garage under lights. Day time temperatures are about 12-15C and night time 7-10C. The lights are on for 16 hrs per day.
