How to Plant Bulbs in Layers (Bulb Lasagna Planting Guide)
A bulb lasagna is an easy way to layer bulbs in one large pot for a fuller, longer-lasting spring flowering display. It is a great option for adding colour to patios, front steps, and outdoor living areas, and also makes a lovely gift.
How it works
By choosing bulbs that flower at slightly different times, the display keeps changing as the season moves along. Early bulbs start the show, with later ones following on, so you get colour for longer from the same pot.

Step-by-step guide
What you'll need
- A large pot or barrel with drainage holes
- Daltons Bulb Mix
- Daltons Bulb Fertiliser
- A selection of bulbs (e.g. daffodils, iris, ranunculus, anemones, freesias)
- Watering can or hose
- Choose a pot that is at least 30–40cm deep and wide. This gives you enough room to plant bulbs at the correct depths and create clear layers without crowding.
- Fill your container: Add Daltons Premium Bulb Mix to the base of your pot, allowing enough depth for layering the bulbs.
- Plant the deepest bulbs first: Start with daffodils, planting them at around 15cm deep. Space evenly across the pot.
- Add the next layer: Cover with more mix, then plant iris at 10–12cm deep.
- Continue layering: Add another layer of mix and plant ranunculus and anemones at 5–7cm deep.
- Finish with the top layer: Plant freesias at 3–5cm deep, just below the surface.
- Feed as you plant: Lightly apply Daltons Premium Bulb Fertiliser between layers to support strong growth and flowering.
- Cover and water in: Top up with mix, water well, and place your pot in a sunny spot.
Top tips

Common questions
How deep should bulbs be planted in layers?
Plant larger bulbs deeper (around 15cm), medium bulbs mid-layer, and smaller bulbs closer to the surface (3–7cm).
Can you mix different bulbs in one pot?
Yes, combining bulbs with different flowering times creates a longer display as each layer blooms in sequence.
Do layered bulbs come back every year?
Some bulbs will return, but in containers they often perform best when replanted each season.
