Can someone please refresh me on the reasons for getting short scapes? I seem to recall (perhaps incorrectly) the reason being a deficiency of some sort, but I don't know what element(s), and if the timing of the deficiency has anything to do with it.
Also, can things other than nutritional deficiencies cause short scapes? A relative lack of water? Temperature swings or cold nights during bud set?
A couple of years ago I planted out 'Ballerina on Ice' and 'Arctic Lace', which were previously in pots that had a fair amount of shade, into the garden. (Their garden location is as close to full sun as I can manage here.) The scapes have been stunted ever since. (I've also had other cultivars not produce scapes to their registered height, whether in shady pots or in a sunnier garden location.)
This is driving me mad, and I'd like to fix it.
