I Divide to Multiply

Filed under: Uncategorized — admin @ 1:49 pm

Greedy for more for plants for new areas of the garden, I divided colchicum, montbretia, and peonies. Greed is an acceptable sin in a gardener.

Colchicums are pricy, but they are worth every penny. They pay out yearly dividends in flowers and they are critter proof. They should be on everyone’s must have list. Their large corms multiply quickly and each sends up clusters of blooms continuing for weeks. Their nickname, autumn crocus is deceiving. They are not crocus at all, although the flowers are similar.

It is also easy to confuse colchicum with daffodils in the spring. Their foliage grows larger, looking like daffodils on steroids. It appears and disappears with the daffodils, although unlike the daffs, they don’t bloom until fall. Then they bloom naked without foliage.

I grow three different varieties of colchicum, ‘Lilac Wonder’, with clusters of single purple blooms 8-inches tall, ‘The Giant’, with clusters of slightly larger single blooms and ‘Water lily’ with clusters of double purple blooms.

 

The process to divide them is simple. After the corms have bloomed, I dig up a clump with a spading fork and gently remove the corms, tiny roots and all, from the mother. I could have done this in late spring too after the foliage died back.

Corms seek their own level. They are often found deeper than I remember planting them. And rightly so, I heap compost on them each fall to nourish them. They also have the ability to move up or down, pulled by their roots, if necessary.

Montbretia (Crocosmia x crocosmiiflora) are among the last summer bulbs to bloom. They send up 2- to 4-foot spikes lined with six-petal, star-shaped flowers in hot colors ranging from yellow to orange to scarlet. Their long, sword-shaped leaves need their own space but their slim hips slip easily between other summer bloomers. 

When I dug up a clump this fall, I was surprised to find clusters of bulbs attached together like pop beads with each cluster only sending up a few flowering stems. Once I broke them apart and replanted them, two inches deep and three inches apart, each bulb has to pull its own weight and send up its own blooms.

Peonies are lifted in the same way, with a spading fork. After they are lifted and rinsed with water, it is easy to count the white or red eyes, pointing up from the roots. I cut the roots apart leaving between 3 and 5 eyes on each division. Then I replant them with an inch and a half of soil over the eyes. The foliage can be cut to the ground.

Once the replanting was done, I began dreaming about next year’s numerous flowers. That’s what gardening is about—a spade, a root, a hope and a dream.

  1. Suzy, I have colchicum in my yard but I absolutely loathe the green foliage in spring. I end up chopping it back which shouldn’t be good for the bulbs but they seem to survive anyway. Also, they flop a lot. I may have either buried them too deep, or they are in too much shade. How do you deal with the spring foliage? It just looks weird in my beds…I’m wondering if there is something I could interplant with…

  2. Shirley,

    You are right, colchicum foliage looks awful in the spring. Sometimes in gardening we have to learn to look the other way. Plants can’t be expected to look great all the time. It is a fact of life that all living things get acne, catch cold, and have bad hair days. Why do we expect our plant to behave as if they were made of plastic? Then again even plastic breaks and fades in color.

    I plant colchicum among green ground covers where the spring foliage blends in. Once they start to yellow I toss the leaves in the compost heap. I do love the flowers.

  3. I have a question when should I divide colchicums (right after they bloom or when then are dormant?) sometimes I loose sight of their exact location would it harm them if they were lifted toooo soon or Late? please let me know many thanks(I often wish I had moved other bulbs but fear loosing them if I move them in an ontimely fashion…….)

  4. YOu can dig them and divide them in the spring or the fall, anytime as long as you dig deep enough and don’t cut off their roots or their foliage before it yellows. It is impossible to find them when they are dorment but if you dig them up by accident you can divide them then too. I like to divide them when the foliage is dying back. The roots are dying back at the same time so I won’t be hurting the bulbs.
