Spring Bulbs - Lasagne Planting
Last year, for the first time, I planted up large planters of spring bulbs which gave me a fantastic early spring display. All the flowers are now finished and the foliage is starting to die back. I am not sure whether I now need to dig up the various 'layers' of bulbs or whether I can just leave them in the pots for next year. Do I cut back dead foliage or just leave it? If it is OK for the bulbs to remain in the pots, could I plant any annuals over them so that there is interest and colour for the summer, as the planters are quite prominent on the patio? Thank you.
