Layered bulb pots
I planted layers of bulbs in pots, for the first time, last year. The crocuses are currently flowering and I'm looking forward to similar displays from the tulips and hyacinths. However, I'm not entirely sure how to deal with them once the flowering has ceased. My understanding is that tulips should be lifted each year, once the foliage has died back; which means that the other bulbs will have to come up too. Is this correct and is it also best to do this with the crocuses and hyacinths too (it would be nice to use the pots elsewhere)?
