Lily bulbs

Ones I had never seemed to bulk up, but you should be able to propagate more from removing scales from the parent bulb. I did say should - never tried it as I got fed up of lily beetles weakening them. Someone did tell me earlier this year that bug clear ultra works on them, so I may try again at some point as I love oriental lilies and snakes head fritillaria (which also used to suffer from attacks)

Before anyone tells me off for using an insecticide it will probably never get used as I never actual do what I intend to do and I would be immensely selective anyway as the wildlife has grown year on year in my garden and really wouldn't want to lose the majority of it.
