What Is Bulb Lasagne Planting? And Why Should You Try It?

But what if, instead of planting just one type of bulb in a pot, you could layer several varieties together and enjoy a succession of flowers throughout spring?

That's where bulb lasagna planting comes in.

Despite its unusual name, bulb lasagna planting is a simple technique that involves planting different types of spring-flowering bulbs at different depths in the same container. With a little planning, one pot can provide several waves of colour as the season progresses.

New to Growing Bulbs in Pots?

Before creating your first bulb lasagna, it's worth getting the basics right.

Our Bulbs in Pots guide covers the essentials, from choosing the right container and compost to selecting suitable bulbs and caring for them throughout the season.

Once you've got the basics covered, bulb lasagna planting is a great way to take your containers a step further.

What Is Bulb Lasagna Planting?

The name gives you a pretty good clue.

Just like a lasagna is built up in layers, bulb lasagna planting involves layering different bulbs within the same pot.

The idea is to combine bulbs that flower at different times, with larger or later-flowering bulbs generally planted deeper and smaller, earlier-flowering bulbs closer to the surface.

As the seasons progress, different bulbs come into flower one after another, creating a changing display rather than everything blooming at once.

For example, you could combine:

Crocus → Daffodils → Tulips

The crocuses can provide an early splash of colour, followed by daffodils, with tulips bringing another display later in spring.

The exact timing will vary depending on the varieties you choose, the weather and where your container is positioned — but the principle is simple:

Layer bulbs with different flowering times and make one pot work harder.

Why Should You Try It?

More Colour From One Pot

Perhaps the biggest advantage is that you can create a much longer-lasting display from a single container. Instead of having one pot of crocuses, another of daffodils and another of tulips, you can combine them to create a succession of flowers.

Great for Smaller Spaces

Don't have a large garden? No problem. A bulb lasagna can work beautifully in a patio pot, on a balcony, beside a front door or anywhere else where growing space is limited.

Make the Most of Your Containers

You're already using the space inside the pot — why not use the depth as well? By planting bulbs at different levels, you can make much better use of the available growing space.

How to Create Your Own Bulb Lasagne

1. Choose a Deep Container

You'll need a container that's deep enough to accommodate several layers of bulbs and compost. A larger, deeper pot gives you more flexibility, particularly if you're planning a three-layer display. Make sure your container has adequate drainage holes — bulbs don't like sitting in waterlogged compost, especially over winter.

We recommend using a good Bulb Planting Compost 20L or our Bulb Compost 10L for smaller pots.

2. Start With Your Deepest Layer

Add compost to the bottom of the pot and position your largest or latest-flowering bulbs according to their recommended planting depth. Tulips and alliums can make good choices for this layer, depending on the varieties selected. Place the bulbs with their growing tips facing upwards, then cover them with compost.

3. Add Your Middle Layer

Add another layer of compost, then place your middle-layer bulbs. Daffodils and hyacinths are popular choices and can provide a lovely transition between the earliest and latest parts of your display. Cover them with another layer of compost.

4. Finish With Your Top Layer

Finally, add your smaller, early-flowering bulbs closer to the surface. Crocuses, Muscaris and Irises reticulata are particularly well suited to this layer. Snowdrops can also be used, although their planting requirements can differ depending on whether they are supplied as dry bulbs or growing plants. Always follow the planting instructions supplied with your bulbs.

5. Water and Leave Them to Establish

Once all your layers are planted, top up the pot with compost and water it thoroughly, allowing excess water to drain away. Then place the container somewhere suitable and let the bulbs establish their roots over autumn and winter.

Don't forget to label your pot. You'll be very glad you did once spring arrives!

A hand bulb planter makes it easy to create neat holes at the right depth for each layer. We also stock a long-handled bulb planter if you prefer to work without bending, and a small stainless steel hand planter for more precise work with smaller bulbs.

Looking After Your Bulb Lasagne Over Winter

Once planted, your bulb lasagne doesn't need much attention.

• Avoid overwatering. Good drainage is essential, particularly during wet winter weather.
• Protect the container when necessary. A sheltered position can help protect your bulbs during particularly harsh weather.
• Watch out for squirrels. Freshly planted bulbs can sometimes attract unwanted attention, so a temporary protective covering can help.

And most importantly, don't disturb the layers just because nothing appears to be happening above the surface. For several months, your bulbs may seem completely invisible. That's exactly what you want — they're busy developing roots beneath the compost, ready for their turn when spring arrives.

Ready to Try Bulb Lasagne Planting?

If you've already mastered the basics of growing bulbs in containers, this is a fun way to take your pots to the next level. Choose bulbs with different flowering times, plant them at their recommended depths, and let nature take care of the rest.

One pot. Several layers. Months of spring colour.
