Everyone wants flowers blooming all the time, right? Since I have been working with plants, I have noticed that people want flowers blooming as much and for as long as possible. I understand why people want flowers blooming all the time because flowers are beautiful! Creating a garden with flowers blooming requires planning, hard work, patience, and time.

An easy way to get a jump start on continuously blooming gardens is to layer your fall-planted bulbs for non-stop blooms. The method of layering your flower bulbs is sometimes referred to as “lasagna gardening” because you build your garden like a delicious pan of lasagna. However, instead of layering noodles, meat, sauce, and cheese you layer lily bulbs, tulip bulbs, allium bulbs, daffodil bulbs, hyacinth bulbs, crocus bulbs and whatever else you’d like to see bloom!

Planning Your Layered Garden

Before you purchase your flower bulbs for your layered garden it is a good idea to come up with a plan. The first part of planning is to determine where you are going to plant your layered garden. How long is the area? How wide is the area? Determine the approximate square footage of the area you are planting to know how many total bulbs you will need.

Fall planted bulbs generally do best in full to partial sun. Therefore, when choosing what bulbs to plant it is a good idea to check that they all have the same light requirements.

Coordinating colors is important in a layered garden since many of the bulbs you are planting will be blooming at the same time or will overlap bloom times with other bulbs in your garden. Determine what color scheme you would like in your layered garden.

Plan for different heights for your layered garden. The bulbs will be layered on each other in the soil based on planting depth. When you arrange them at the time of planting you will want the tallest plants in the back of the planting area, and shorter bulbs in the front.

Planting Your Layered Garden

One of the many benefits of layered gardening is that it will enables you to plant more bulbs in a smaller area because it allows for more space for each root system. With this planting method you can easily attain early season, midseason and late-season blooms all in one area or container through a little bit of planning.

You will first want to determine the bulb in your lasagna that has the deepest planting depth. For fall planting: lilies, allium, and fritillaria are larger bulbs and generally require the deepest planting depth so if you would like to plant these in your garden bed, you will want to plant those first. Backfill with soil and plant the bulbs that have the next deepest planting depth.

Tulips, daffodils, and hyacinths require at least 6” of planting depth and will most likely be the next bulbs in your layer. Backfill again with soil and add the next layer of bulbs to the planting area.

Bulbs such as dutch iris, dwarf daffodils, crocus, and certain specialty bulbs should be planted at a more shallow depth. Generally, these bulbs are planted 2-4” deep. These bulbs should be planted next in the layers. Backfill again with soil and put the last layer.

The last layer will consist of any roots or bulbs that are to be planted at a 1-2” depth. Perennials and bulbs with 1-2” planting depth are peonies, bearded iris, and bare root perennials such as daylilies, bleeding hearts, and poppies.

If planned carefully you could even have blooms from spring until later summer by planting lilies and herbaceous perennials in the planting area. The options are endless, so get out the big spoon and start digging into some lasagna gardening!
