If you’ve never heard of a bulb lasagne you’re probably raising your eyebrows right now. It is a real gardening ‘thing’ though!
What is a bulb lasagne?
A bulb lasagne is a clever way of layering up spring-flowering bulbs to create a display of flowers that lasts for months. It’s really easy to do and will give you a lovely display throughout the winter months for very little effort. What’s not to like?
Can you layer bulbs?
Bulbs will be perfectly happy to be layered up in a container. The important thing to get right is the order in which you plant them. The ones that flower first should be planted on the top layer, with the ones that flower next on the second layer, and so on.
When is the best time to plant spring bulbs?
It’s important to plant bulbs at the right time of year, and this varies according to the variety you choose; check the packaging if you’re not sure. Spring flowering bulbs should be planted in autumn.
If you want to plant a bulb lasagne with bulbs that flower in summer, such as gladioli and dahlias, you need to plant it in spring.
Can I plant on top of bulbs?
Absolutely. Winter bedding plants are a great way to give your display a head start before the bulbs flower.
How to plant a bulb lasagne
This time of year is perfect for planting spring flowering bulbs, so if you’d like to have a go at planting a bulb lasagne, here’s how to do it.
Assemble your bulb lasagne ingredients
You’ll need a variety of *bulbs that flower at different times for your container. The aim is to get a lovely display of flowers for as long as possible, so check the flowering month on the bulb packet before you buy.
Prepare your container
When planting a bulb lasagne you’re after a big impact, so you need to pack the container full of bulbs; bear this in mind when choosing a size.
It’s a good idea to put some ‘crocks’ (broken pieces of pot) in the bottom of the container to help with drainage, then half fill the pot with general purpose compost.
Plant your bulb layers
Plant the latest flowering bulbs in the half-full container, then cover them over with compost.
The bulbs that flower before the bottom layer go in next; again, cover them over with compost.
The top layer should be the bulbs that flower first.
It’s important you plant your bulbs in the right order, and it’s surprisingly easy to get mixed up! I’ve found that laying out each variety in a line before I start really helps.
While you’re planting your bulbs, you might want to save a few and force them to flower early for a lovely indoor display. Find out how to do that here.
Add plants to the top of your container
Your bulbs won’t flower until late winter, so you need to add plants to the top of the container to create a lovely display in the meantime.
Keep your container moist but don’t be tempted to over-water; bulbs hate sitting in cold, soggy soil.
What to plant with bulbs in containers
Winter flowering pansies, violas, cyclamen and heather are all great options for the top of your bulb lasagne. I think it’s also worth adding in some foliage plants such as ivy, heuchera or cineraria to really boost the impact.
Great bulbs to plant in a bulb lasagne
Here are some ideas for *spring bulbs which you could use on each layer of your lasagne:
Bottom layer: tulips, hyacinth
Next layer: narcissus, daffodils, anemone, muscari
Top layer: snowdrop, crocus, miniature iris
What to do with bulbs in containers after flowering
Your bulb lasagne should flower for you year after year, but the bulbs will benefit from a feed after a couple of seasons.
If you’d rather not leave your bulbs in their container, you can dig them up once the foliage has died back and dry them out, then store them. I have to admit I’ve never bothered doing this though, I like the low-maintenance element of leaving well alone!
I do replace the top layer of compost when I change the bedding plants, to give the whole container some fresh nutrients.
And that’s it – a quick garden job that will give you lots of blooms to enjoy in the depths of winter 🙂
Do you think you’ll be planting a bulb lasagne? I’d love to hear what you choose to plant, I’ve still got some containers to fill so inspire me!
