Last year I planted up a pot of mixed miniature iris for my brother, which, to his delight and my surprise, came up well. So this year I am trying planting up a terracotta bowl of crocus. I know these can be planted straight out but I'm hoping by sheltering them in the garage overwinter they will bloom earlier.
As plants in patio pots and tubs die back, these can be revitalised for winter colour with wintering flowering pansies, violas and heathers. Or 'layered up' with a selection of bulbs. Providing the compost is disease and pest free (the dreaded vine weevil grubs) then remove any roots, mix in some slow release fertiliser and you're ready to go. The larger bulbs (such as daffodils and tulips) should go near the bottom with the smaller varieties in successive layers above. Top off with some fresh compost if necessary and leave outside, preferably in a sheltered spot out of the worst of the weather. Good drainage is vital to prevent the bulbs from rotting in wet conditions.
