I had a wonderful display from Allium Schubertii last year. This year, just a few starggly leaves. I have now dug them up to investigate: the bulbs are large, firm and well-shaped - but appaer to have no roots! Should I keep them and replant in the Autumn? If so, do I keep them dry until then or put them in pots and keep moist?
They have no roots now as they have gone into their Summer rest. They aestivate. You can dry them off and replant in Autumn if you have already dug them up. Watch out for mould growing on them, sprinkle a bit of Sulphur on them . The shops seem to store them in wood shavings, but a paper bag somewhere dry and cool should be good.
yet i have had a better year with all my alliums, big globes purple and the smaller ones cant remember all the names, and frittilia, even customers have remarked how theirs have come on too, all this rain? but the rest of my garden needs some sun.
