Hi



Thanks for the letters.



I just read in Adrian Slack's book that it is best to wait until there is at least 4 crowns.



After division, do you suggest that the plants should be given less hot sun than before division?



Also, I may buy some second hand pots from a nursery that may be dirty. Is it worth the trouble to sterilize the pots by possibly dipping in a bleach solution or would just a quick rinse be all right?



Your help is appreciated
Regards Richard.
