potting on


There is definitely an optimum time to do pot on. We prick out into 
cell trays and pot on into 9cm pots  just as soon as the root ball 
will come out without disintegrating. We then pot on before the plant 
starts to show signs of stress (in theory anyway)

As well as wondering how long a plant should be left before potting
on I am interested in how big a pot on can be made and the
balance between giving enough room and too much. Aspects such as the
changing microclimate ( speed of soil cooling/warming, humidity
levels, drying out, air movement etc) and their balance against the
labour cost (monetary or otherwise) of potting on and/or spacing.
It seems there is a vast range of possibilities for control and 
growth optimization/retarding here,not just for the commercial grower 
but the home gardener too.

I have large flowering Kale in my vege/flower garden now (just 
planted out of 17cm pots) and very tiny flowering kale that were 
surplus to requirements and remained in the cell trays.
