Hi, Brian. I don't know how A. belladonna behaves in the UK, but here in California they grow close to the surface, either with the tops at soil level or with the top quarter of the bulbs exposed. In my garden, blooming tapers off when the clumps get very crowded, although some of the bulbs in a clump will generally bloom each year. Longtime Amaryllis grower and breeder Les Hannibal said the best time to transplant them is during or just after bloom, because the roots are just starting to grow and the plant can more easily regenerate them. If you get the timing right, they won't necessarily skip the next year's blooms. They definitely do not appreciate root disturbance at other times of the year. Hope that helps.
