Growing Bulbs, Rhizomes & Corms in Containers
I love container gardening, especially with a variety of bulbs, rhizomes and corms. It’s so easy and they come back beautifully year after year. Plus, many of them make a lot of babies that you can give away to friends and family. I like to grow them in containers for a couple of reasons:
- Love to put them front and center when they are blossoming.
- Easy to put them aside when dormant.
Most of my bulbs, rhizomes and corms in containers are spring blooming. They start to emerge in the fall/winter, bloom in the spring and are mostly dormant over the summer. It’s important to let foliage continue to grow after blooming; this is how they gain energy for the subsequent year. I stop watering when foliage dies back. While dormant, I place all my containers in a shady area within our cottonwood grove. Though watch out for critters. One year some hens got out and ate up some of my tiny bulbs.
Repotting & Refreshing Potting Soil
At least every two years, I repot all of my containers. First, I sift all the soil through a compost screen so that I don’t miss any bulbs or corms. Though it is a little tricky to get all of the tiny bulblets and cormlets. That means that some babies and seeds may end up in other containers.
I reuse the old potting soil by mixing in some kelp, perlite, vermiculite, as well as bone and blood meal. I use about 50/50 old and new potting soil. I also add in some organic granular bulb food (Jobe’s Espoma and Dr. Earth are all good choices), but don’t let it touch the bulb or corm.
