How to successfully propagate Begonia maculata

Time needed: 5 minutes

There are a few different methods for propagating this beautiful plant, and this guide will help you each step of the way.

Identify your cutting point.
When it comes to propagating your Begonia maculata, one of the most common questions is “where do I cut?” This is the first step of the process, and there is no need to overthink it! I have propagated plants from branches that have broken off unintentionally before.

Some people like to make small cuttings, while other people like to leave some height on the cutting so the plant is sturdier. Find a good spot about one inch above a node (where a leaf meets a stem). I like taking a larger cutting when I’m pruning to keep the new plant nice and sturdy.
Make your cutting.
Using sharp scissors that have been wiped down with alcohol, make a slanted cut at your desired cutting point. The slanted cut makes it easier to place the cutting in soil. If you’re propagating in water, this is not necessary.
Remove lower leaves.
You’ll want to remove any of the lower leaves that will be placed in your propagation medium.
Choose your propagation medium.
You can propagate your Begonia maculata stem cuttings in fresh soil, in perlite, or use the water propagation method. I prefer using water propagation in a clear container because I like to see what’s going on with the root system every day.
Place your cutting and provide the ideal conditions.
After placing your cutting in your desired medium, all you have to do is wait! I find that the new roots grow pretty quickly. If you’re propagating in soil, you’ll want to keep the soil moist (but avoid overly-soggy soil).

If you’re propagating in water, be sure to keep an eye on the water level and change it out at least once a week. I also like to add a few drops of fertilizer as soon as the roots begin to establish. Be sure your new cutting is receiving enough light to thrive. If you don’t have a good sunny window, a grow light will work just fine.
Wait for roots to grow!
After some time, you’ll notice roots beginning to grow. This process can take several weeks, so it’s important to be patient. After your roots are a few inches long, you can transfer your plant to soil.

Typically, this is an issue with the amount of light your plant is getting. Make sure your plant is getting enough light for proper growth.

It’s incredibly rewarding to admire the spotted leaves, fast growth, and beautiful white flowers!
