In many cases, the size of a terrace or balcony is the limiting factor for the number of species and colours of flower bulbs that can be enjoyed in spring. For gardeners with limited space, the "lasagna system" or "layered planting" of bulbs can be a good solution. On the right is an image that visually shows the concept (in this case crocuses, hyacinths and tulips)
By layering bulb varieties one above the other in the same pot or container you create longlasting and/or many colours in one relatively small place. There are two ways to go about layering bulbs:
1. Combining different colours or varieties that bloom simultaneously.
The tallest plants are planted at the bottom of this. Some combinations could for example be:
Dwarf daffodil "Tête à Tête" and / or Muscari 'White Magic' on top, Hyacinth 'Delft Blue' in the middle, and early Tulip "Calgary" on the bottom.
You can also experiment with just one dominant colour such as a combination of the orange / yellow dwarf daffodil "Jetfire", Hyacinth 'Gipsy Queen", and Tulip "Hermitage".
2. Combining bulb varieties that bloom in succession for an extra-long flowering period.
Early flowering bulbs such as crocus or dwarf daffodils will be planted on top, and later bloomers like tulips should be planted at the bottom of the pot. Possible combinations could include:
Crocus "Flower Record” on top, Hyacinth'”Purple Sensation” in the middle, and Tulip “Passionale" below. This combination gives a beautiful purple-coloured flower pot or container from late February to early May.
Another combination for a long-flowering pot or container could for example consist of Crocus "Joan of Arc", Narcissus “Thalia”, Hyacinth "Aiolos" and Tulip "Inzell".
When planting in pots or containers ensure that there is a drainage hole at the bottom, so that abundant water can drain away. Don’t forget to first put a layer of stone shards or pebbles in the bottom of the pot before adding compost. This allows for better drainage and prevents the drain hole from getting clogged up immediately. Then each time you plant a layer of bulbs and inbetween you add a layer of soil.
The above suggestions are of course only a few ideas, but there are many more combinations you can create. Using the colour and blooming time search features in the spring bulb category of our webshop, it is now easy to create some very nice combinations for your own bulb lasagna.
