Itās a little something called Bulb Lasagna
The fall bulb parade continuesāand this week Iām sharing a bulb trick that blew my mind.
Itās a technique for planting spring blooms in flower pots called ābulb lasagna.ā
Bulb lasagna?
Yep, you read that right!
Also known as ābulb layering,ā it refers to layering different types of flower bulbs in one large flower pot.
The result is one flower pot with a sequence of blooms continuously through spring. This is an extra special feat, considering almost no spring flower blooms the entire season.
How it works
Bulb lasagnas are remarkable because of how the bulbs navigate growth.
At first glance, it might seem that layers of bulbs would be overcrowded, or that lower layers of bulbs would surely be stunted by upper layers.
But fall bulbs are both hardy and adaptableāthey figure it out. Bulbs on the bottom of the pot grow around and through the upper layers, all the flowers making room for the others as they grow.
The key to doing this successfully is planting layers based on the flowerās bloom time.
Understanding bloom times
There are three primary bloom times:
Early spring
Mid spring
Late spring
These bloom times are widely recognized across nurseries and growers. Any bulb you buy will state its bloom time on the package or website description.
(PS. More details on bloom times and sequencing are in the Spring-flowering bulb guide.)
Try it this fall
Hereās what youāll need:
2-3 layers of flower bulbs. The bottom layer should bloom earliest, and the top layer should bloom the latest. Late-season tulips, mid-season daffodils and earl-season crocuses are a go-to combination, but feel free to experiment.
Flower pot. Iād recommend at least a 12ā pot.
Drainage material. This could take the form of rocks, broken up terracotta, or re-used packing peanuts.
Nutrient-rich potting soil
Optional: gravel
Instructions:
Note: Spring-flowering bulbs must be planted in the fall
Place a layer of drainage material at the bottom of the pot.
Add a layer of potting soil, about 8ā deep. Optional: Mix gravel into your potting soil to increase drainage
Add the first layer of bulbsāthe latest-flowering ones of the mix. Place them close together, but not touchingāthe space between should be about the width of the bulb.
Add 3-4ā of potting soil over top, then plant your middle layer. Use the same spacing rule as the first layerāabout a bulbās width apart.
Add soil over top, until the surface is fairly close to the top of the pot (a few inches below the rim). Place your final layerāthe smallest bulbs of the bunch. Press them into the soil surface, and cover with a final thin layer of soil.
The pots can live outside through the winter, but need protection from deep freezes. Cover them with hay or bubble wrap to keep protected. Alternatively, leave them in a cold but protected place, like a garage, until February.
The show begins in late winter or early spring, depending on your top layer of bulbs. When the pot finishes booming, remove the bulbs and store them for next year, plant them in the garden, or just keep them in their pot for next year!

š What Iām reading
My copy of The Overstory by Richard Powers just arrived. All I know is that itās a novel all about the wonder of trees. Which is all I really need to get excited about it!
š What Iām inspired by
Iāve been looking deeper into the works of Hieronymus Bosch. And if you know his work, you know the depths of it know no bounds.
Something that strikes me with Bosch is how fantastical and absurd his subject matter isānot something one would expect from his time (late 15th century/early 16th century).
I bet he would have been fun to have a coffee with.
