Hello, I planted 5 original Globemaster alliums about 4 years ago which have now split into 3 or 4 bulbs each - they all flowered last year but I completely forgot to split them in the autumn - out of sight out of mind! Now they are all showing themselves again, some are 5 inches, some only 2 inches. Would I be completely mad to - extremely carefully, dig them up and split them now? Thanks, Wren
