The Bulb Lasagna Method

Bulb lasagna or bulb layering is a technique of layering bulbs in containers that will produce a miniature bulb display next spring. By choosing a variety of bulbs that all bloom within a few weeks of each other you can create continuous blooms for nearly two months.

The most important consideration in creating a bulb lasagna is choosing a container that is both wide enough and deep enough. For example, a 10-inch deep container can only hold two layers of bulbs and a 14-inch deep container will hold three layers of bulbs. Choose bulbs that grow to different heights to create a more interesting spring display. For example, a classic combination is tulips, daffodils and grape hyacinth. Avoid planting bulbs too close to the sides of the pot. Bulbs perform better in groupings - read the planting depth instructions on the bulb packaging when designing your layered container garden to ensure that your plan will work with the container you’ve chosen.

To layer, first place a layer of gravel across the bottom of the container, then apply a thick layer of potting soil mixed with bulb food. Place the first layer of bulbs in the pot and cover with a layer of soil. Continue layering. Cover the top layer of bulbs with a final layer of soil, as if you were planting outdoors.

Water thoroughly, then let the fall rains take over. And anticipate a beautiful spring!

Molbak's tip: if you don't want to look at a bare pot of soil all winter, overplant with a combination of Pansies, Heuchera, Hardy Cyclamen, Dusty Miller and small grasses. The bulbs will poke up through in spring!

For weeks  of continuous bloom.
If you are planting three layers of bulbs in your container, consider the following options:

Top layer:
Muscari, Crocus, Scilla, Chionodoxa, Puschkinia, Tritelia, Ixia, Freesia

Middle layer:
Tulips, Hyacinth, Galanthus

Bottom layer:
Daffodils, Allium, Fritillaria, Camassia, Lilies, Ipheon
