Begonia Propagation

A couple days ago, I demonstrated how to make a leaf cutting, and grow lots of plants from one healthy leaf.
Today, I’ll show you how to grow a new plant from a stem cutting.
This begonia has spectacular silver leaves with a red reverse. It originally was a gift from a friend, presented in a glass of water, where it rooted with ease.
I’ve propagated many plants from that original cutting.

Late winter is a great time of year to take cuttings because the plants are gaining vigor with the growing length of daylight hours.(Just like us!)
The growth trigger has been pulled and they’re ready to push out a lot of new growth, both in leaves and roots.

The photo above shows a gangly stem that is a good candidate for cutting.
Cutting with Rootone

Leave just the newest two or three leaves on the stem and gently strip off the rest.
With a sanitized implement, (I used a knife), trim the stem back to about 3 inches, leaving a healthy succulent stem, with a couple perfect leaves.
Next, dip the stem into rooting hormone, tapping off the excess. The roots will emerge from the nodes where you pulled off the leaves, so make sure you dust all the nodes carefully.

Begonia in Vermiculite Fill a small plastic container with dampened vermiculite. Using a chopstick, make a hole in the center of the container, large enough and deep enough to accept the begonia stem.
Insert the stem without brushing off the rooting hormone, and gently firm the planting medium around the stem.

In Baggie Place the container in a ziplock baggie, and set it in bright area out of direct sunlight.

In two or three weeks, open the bag and give the stem a little tug.
When the plant seems firmly ensconced in the vermiculite, it is ready to be transplanted into a pot using potting soil.

Give it a diluted dose of fertilizer now and then, and you will have a gorgeous plant to propagate from again and again.

    Martha always makes sure to tell readers where they can find a particular product or ingredient with a website or store mentioned. In this case, where would I find Rootone and bags of vermiculite? What’s obvious to you may not be for “all-thumbs” readers (as opposed to “green-thumbs” : )
