In the post on miniature garden bulbs for small-space gardens, I recommended some of my favorite small bulbs. But I mentioned that I also grow larger bulbs like tulips, daffodils, and hyacinths. Look around this garden blog and you'll come across other large bulbs like alliums, Oriental and Asiatic lilies, and they all live pretty much in harmony in a very small urban front yard. Below I'll give you my tips on how to layer garden bulbs.
How to Plant Spring-Blooming Bulbs by Layering:Ignore the roots in the photos of my bulbs. These bulbs were already growing in my garden when I decided to condense the plantings by layering the bulbs. When you buy your bulbs from the garden center, they will not have roots and that's perfectly fine.
Visit your local garden center and buy all the bulbs you're interested in planting in your garden. Choose a sunny, well-draining section of the garden you want to plant your bulbs in. Take the largest bulbs like tulips, daffodils, lilies and hyacinths and plant them at the recommended planting depth on the packaging. Did you toss the packaging before reading the planting depth suggestion? Well, I generally plant them about twice as deep as they are tall. You can also plant them as deep as the blade on your garden trowel. Can't find your garden trowel? Just plant the bulbs about 6-8 inches deep.
Once you've planted in your large bulbs, cover the bulbs with about 1-2 inches of the same soil you dug out of that hole. Directly over that, you will plant your miniature narcissus, crocus, grape hyacinths, scilla and any other small bulbs that caught your fancy at the garden center. Now fill in the hole with the rest of the soil. It may be a good idea to leave some kind of plant tag or garden marker over newly planted bulbs to remind you not to step or dig there.
In the spring the small bulbs will break dormancy first and begin to flower. By the time the small bulbs have stopped blooming it will be time for the larger bulbs to put on show of flowers in the garden. Keep in mind that bulbs look better planted in masses so don't plant just one or two bulbs per hole. Plant your larger bulbs in groups of four or more.
Are you gardening on a balcony or patio and don't have ground you can plant bulbs in?Layering spring-flowering garden bulbs in containers and raised beds works too. Although, if you're planting or transplanting iris rhizomes, I do not recommend layering any bulbs below them as iris clumps need more room and will quickly outcompete any bulbs planted below them. Plant them in a separate spot.
Do you layer garden bulbs in your garden or containers? What's your favorite combination of bulbs to plant together?
