I planted a bishop of LLandaff last year and a bishop of York this year.The llandaff came back with a vengeance this year. My question is when do I need to seperate the bulbs? Do I wait for them to die off for the year or just stop flowering? Also my bishop of york is quite small as it was only planted this summer so do I leave it? Do I just store the tubers in a plastic bag for the winter and plant in spring?
