I have four large, deep containers at the front of the house that I plant up using this method. After about 4 or 5 years I replace the soil and re-plant them with new bulbs - this lot came from the RHS online shop as a package for layering: crocuses, muscari, hyacinths and tulips. The top layer of soil is deep enough to plant pansies, heathers, cyclames etc in the autumn before the bulbs come through and bedding plants after the greenery dies back.
At the back of the house, which is mainly paved with stone, I have a collection of smaller pots and troughs, mostly terracotta and stone. I plant these with just one variety of bulbs each and move them round so that I can see them from the house when they are in flower and at their best. In the summer I fill them with bedding plants.
The ones at the back will need replanting this year as a family of squirrels moved in last winter and they dug up some of the bulbs and ate them! I also have an odd assortment of bedding plants this year as the nursery where I get my plants was closed during lockdown and when it re-opened I just bought what was available!
