re: amputated 'Raspberry Ice'
I've been removing the upper two rows of mature stem leaves, to allow more room and light to the "resurrection chicks", the 12 I potted up still look fine, and there are about 15 more lengthening chicks on what's left of the chicks.
Raspberry Ice, view of resprouting chicks, and when I pulled off some of the mature leaves to allow from for chicks, I potted a few leaves up as cuttings, on the left, purely an experiment.
View of my shaded Semp surgical recovery area. I might end up with nearly 30 'Raspberry Ice' if all of the regenerated chicks survive, and more if per chance the leaf cuttings work. In lower left center is 'Kip' just starting to show re-emerging growth after surgery.
