Houseplant Hacks: Schlumbergera Propagation

Christmas or Thanksgiving cactus plants may become another family heirloom.  Long lived and easy to care for, this is a quintessential ‘pass along plant’  you may be gifted with during the holidays.

Whether someone gives you one in full bloom in a little foil wrapped pot, or a well-meaning aunt insists on sending a cutting home with you, this is the season when many families enjoy a blooming cactus as a part of their holiday.

I can’t remember a time when my own mother didn’t have a Christmas cactus.  Her first one began as a gifted cutting from someone in the extended family.  At one time it had grown to a monstrous size, maybe 20″ or more around in a  large clay pot.  I never gave this ugly duckling house plant much consideration in those years, probably because hers didn’t often bloom.

Once you’ve enjoyed the vivid, decidedly odd blooms of a Schlumbergera on a wintery day, you may develop an appetite for these unusual plants just as I have.  Their extravagant flowers are meant to attract hummingbirds to pollinate them.  I love to have one in full bloom indoors when its snowing outside.

The ‘off’ bloom schedule of these beautiful tropical cacti may have something to do with their country and hemisphere of origin.  They were originally collected from the mountainous coastal forests of southeastern Brazil, where they grow in bright, humid shade.  They may be found growing high up in trees on moss covered branches, or in small pockets of soil in rocky areas at high altitudes.

They were in cultivation in Europe by the early 19th Century, where breeders developed new cultivars for the market.  They were enjoyed both in homes and in fashionable heated greenhouses.

Although a cactus, these plants have no spines to stick you.   A succulent, they don’t require a great deal of care.  They offer a bulky green presence year round, bursting into abundant vivid bloom  between late October and late February each year.

Schlumbergera commonly turn up in grocery stores and garden centers blooming in shades of red, pink and purple.  Sometimes you may find one with white blooms touched with vivid rose.  More rarely, they can be found blooming  in shades of salmon, yellow or orange.

This is one reason it pays to know how to root a Christmas cactus.  Once you find one of the rarer colors, you might want to produce more to share, or for your own collection.

Another reason is that the stems, which look like flat leaves, can sometimes be a bit fragile.  A section may break off while you are moving the plant or while you are moving around the plant.  When this happens, it feels nicer to root the broken piece than to discard it.

I’ve tried many different ways to root these odd green stems over the years.  The stems don’t really like to sit in water, though I’ve seen my mother root them this way.  They also don’t root reliably when simply stuck into some potting soil, though this sometimes works OK.  If the stars don’t align, or the temperature and humidity aren’t just right, then your efforts may be rewarded with a shriveled or mushy bit of stem with no roots to sustain it.

~

I experimented with a new technique for rooting a Christmas cactus stem in extremely shallow water, on moist rocks.

~

I was understandably excited when I saw a pin on Pinterest a few months ago, offering a novel way to root Schlumbergera.  The key to the wet rock method is to understand that Schlumbergera  naturally grow in a humid, coastal forest, high up in the mountains.  High humidity is the key, along with keeping the stem mostly dry, with only the growing tip in water.

Begin with a glass or small jar, and add a few inches of clean, attractive rocks.  Fill your glass with just enough fresh, cool water, to barely cover most of the rocks.  Then add your cuttings so that they rest on the rocks in very shallow water.  It works best to ‘twist’ the cutting from the parent plant rather than using scissors to remove it.

You will need at least 1 full stem section, though you may take a cutting a few inches long, like this one.  If the cutting already has flower buds, they will continue to grow as your cutting roots.

~

~

Place your container and cuttings into a bright, cool window sill, where the cuttings will get bright light, but minimal direct sunlight.  Keep the water replenished every few days, and watch for those roots to grow.

Once the roots are at least 1/4″ long, you can pot up your rooted cutting in a peat based soil mix with a little grit.  The soil needs to drain easily.  Keep the soil just moist, but never really wet and never bone dry.

~

This cutting is ready to pot up in good quality peat based potting mix.  Add a little fine grit to improve drainage.  If you plant into a container without drainage holes, be sure to begin with a few inches of gravel in the bottom of the container for drainage.

~

I  feed my Christmas cactus monthly, during their season of bloom, with diluted orchid fertilizer; which keeps the buds coming.  Mine live near a large window where they get bright light during the daytime, but they also get natural darkness in late afternoon.  They like long nights and shorter days during their season of bloom.  The long nights help trigger bud formation. Shlumbergera also use more water when they are blooming, and of course thrive in a humid environment.

If your home has very dry air in winter, then try grouping them together, and consider setting the pots on trays of pebbles with a bit of standing water in the tray.

~

This cutting rooted in the glass on moist rocks. After a few weeks, I planted it in its own little container to grow on until spring.

~

In our climate, Christmas cactus thrive in bright shade on the deck all summer long.  I move them out in late April, once danger of frost has passed.  They love our humidity and grow lush with very little attention until time to bring them in ahead of the first fall frosts in late October.  By then, they have covered themselves in flower buds.

Keep your plants large and lush by adding rooted cuttings to your established pots of Christmas cactus.  They like a tight fit for their roots in the pot, but do pot them up every few years and give them some fresh, fertile soil.

~

~

If your space allows, plant Christmas cactus in hanging planters, or set the pots up on plant stands where their drooping branches and long, pendulous flowers may be admired.   I’ve even seen a grouping of Christmas cactus pots arranged on a plant stand with layers of shelves, to give the illusion of a blooming Christmas tree.

These odd houseplants are extremely easy and rewarding to grow, once you know a few hacks to make your efforts more successful.

Do you feel better surrounded by green growing things?

These very gentle and generous beings have a certain presence.  It is one reason why we feel relaxed and peaceful in our home surrounded by a forest.

Which makes January and February such a challenge.  Most of our garden still slumbers through its winter dormancy.

Yes, the daffodils have begun to send up a few leaves here and there to test the air…. but we’re still just hanging on here.  Many reading this may simply wish to see the ground again, as their garden slumbers under its thick covering of snow and ice.

Which might explain why the tiniest little plants bring such joy today.  Even a narrow windowsill can hold a very satisfying micro garden in February.

It is the energy of growth which attracts us.  And watching their tiny unfoldings offers us a meditation on the nature of our own lives.

Some find peace in the simplicity and sparseness of winter.  I find joy in watching life spin itself in new growth from the simple elements of water, air, and light.

There are lessons to be learned from this intimate observation of the infinite.

All you need is a tiny container.  Depending on what you choose to grow, a little sand, a little water, or perhaps a little soil will sustain the tiny life you cradle there.

This is the season when every bit of plant matter is ‘juiced,’ just waiting for the proper conditions to burst into another season of growth. 

Whether you scrape up a bit of moss, save a carrot top, plant a bean or garlic clove, suspend a sweet potato in water or moist sand, or even stand a cutting in a jar of water; the wonders of life will unfold right in front of your eyes.

You don’t need acres of land to share in the mystery.  You don’t need an investment of cash.

Just see the possibility.   Offer warmth and water.

And prepare to be amazed.
