Planting spring bulbs is one of the easiest and most rewarding ways to add life and colour to your garden after winter. But if you want a longer flowering season, the secret lies in bulb layering — also known as the 'lasagne method'.
In this quick guide, we'll show you how to layer bulbs like a pro to enjoy months of continuous blooms with minimal effort.
What Is Bulb Layering?
Bulb layering means planting different types of bulbs at different depths in the same container or garden bed. Each bulb type blooms at its own time, giving you a succession of flowers from late winter through to early summer.
Think of it like a lasagne - deeper bulbs first, shallower bulbs on top.
What You'll Need
-
A deep container or garden bed (at least 30cm deep)
-
Bulbs of different bloom times:
-
Bottom layer (deepest): Tulips, Alliums (late spring)
-
Middle layer: Daffodils, Hyacinths (mid-spring)
-
Top layer: Crocus, Snowdrops, Iris reticulata (early spring)
-
Multi-purpose compost or bulb planting compost
-
Watering can
Step-by-Step Guide
- Add compost - Start with a 10cm layer of compost at the bottom of your container.
- Plant the deepest bulbs - Place tulips or alliums at the base, spaced slightly apart. Cover with 5-7cm of compost.
- Add mid-depth bulbs - Next, add daffodils or hyacinths. Again, cover with compost.
- Top with early bloomers - Finish with crocus or small irises. Add final compost layer, water gently, and you're done.
