Layered Bulbs in Pots: An Emerson Wild Guide

After your garden has been officially closed, but before the season of merriment begins, one outstanding item remains on our list. Spring bulbs. Planted in the Autumn to allow for a long period of dormancy; the extra effort right at the end of the season, yields a great joy in the Spring. While we’ve reviewed the basics of bulbs and our individual favourites, here we dive into the elevated approach of layered bulbs in pots, sometimes called “lasagna planting”.

The Art of Layered Bulbs

If you’re unfamiliar with the term, it’s simply planting various kind of bulbs in order of their expected bloom time. The idea is to plant the latest blooms deepest and the first to burst through (even snow sometimes!) are only a few inches from the top. Funnily enough, bulb size is directly proportional to the depth of planting and size of eventual flower; which upon reflection is a very easy conclusion to reach, but an interesting fact nonetheless. And while bulbs are forgiving (think of the planting completed by squirrels) to achieve a seamless succession of florals, a bit of planning is needed.

What’s Needed

• A large/deep winterized container with ample drainage (size will depend on how many layers/the size of bulbs you select)
• All-purpose soil + manure for layers and mulch for top-dressing
• 2-8 types of bulbs for your “layers”
• Chicken wire or some kind of pot protection – essential for critter protection and prevention 

The Layers

Like other kinds of container planting, you choose your own adventure. If it is your first time utilizing the lasagna planting, consider starting with 2-3 layers with one kind per layer. As you get more comfortable with this method, work your way to 4 layers with 2-3 different bulbs per layer for a truly show-stopping display. Simply arrange your selections based on their required depth and expected bloom time. Earliest will go at the top, latest the deepest. Furthermore, if ever in doubt between two types of bulbs, remember size is a fairly consistent indicator for placement.

1. Start with a good amount of soil and mix in a few handful for manure.
2. Begin with your deepest planting and arrange your bulbs as accorded by package; some can be packed while others need more initial room. The small hairy roots are placed into the soil, if none appear, the rounder side is usually the bottom. No need to fret if you’re still unsure, the plant will always grow up!
3. Cover with a layer of soil and add next layer of bulbs. Continue until all your bulbs are planted.
4. Add a thick layer of mulch and finally affix your critter protection. This is essential the digging of various squirrels and rodents could disturb your arrangements or worse rob them of several bulbs.

Julie reminds us, “Aim to create a cohesive yet striking visual appeal with careful consideration not just with type of floral, but with colour, texture and height. I love to work with complimenting colours, singular blooms next to inflorescences and introducing lush scents where possible.”

Things to Remember

If buying from a catalogue, purchase from a trusted source. When shopping at your local nursery or garden center however, you can easily spot high quality bulbs. To begin with, bulbs should be firm throughout, free from overwhelming mold and have a bit of weight to them. Avoid bulbs that are soft, shriveling or disfigured with any kinds of blemishes or spots. Bigger is often better; with some exception, but usually you’ll want to go for the average or slightly larger if possible.

Keep a detailed description of what you end up planting. Document and journal the process. Note specific cultivars purchases, notes on bulbs and overall performance the following Spring. This little extra step allows for a marvellous natural connection, adding another layer to how you interact with your gardens each year.

May your layered bulbs blooms boldly and beautifully next Spring.
