Everyone is talking about lasagne pots and they are very easy to put together and really effective.
Choose a selection of bulbs that will flower in succession, planting the latest to flower on the bottom layer of compost with compost between each group. Top the pot off with some violas and the bulbs will come through in the spring and look gorgeous. Some will inevitably overlap so choose colours that will compliment one another.
It is easy to choose a selection that can be colourful from February to late May.
