How to Propagate Rattlesnake Plant in Water

Rattlesnake plant, also known as Calathea lancifolia or Calathea insignis, is a popular houseplant known for its attractive foliage. If you're looking to expand your collection, propagating rattlesnake plants in water is a great option. Here's how.

Step 1: Choose a Healthy Parent Plant

The first step to propagate rattlesnake plant into water is to choose a healthy parent plant. Look for a plant that has a few healthy leaves and stems. Check the leaves for signs of pests or disease, and avoid plants that have any issues.

Step 2: Cut off a Stem from the Parent Plant

Once you have a healthy parent plant, the next step is to cut off a stem. Choose a stem that has a few leaves and is at least four inches long. Use a clean and sharp pair of scissors or pruning shears to make the cut.

Step 3: Prepare a Vase or Jar with Water

After you have a stem cutting, the next step is to prepare a vase or jar with water. Use a clear glass vase or jar so you can easily monitor the growth of the roots. Fill the container with room temperature water, and make sure to change the water every few days to keep it fresh.

Step 4: Place the Stem Cutting in the Water

Gently place the stem cutting in the water, making sure that the bottom of the stem is covered in water. The leaves should be above the water level, so they don't rot. You may want to use a toothpick or chopstick to keep the stem cutting upright.

Step 5: Place the Container in a Bright and Warm Location

Put the container with the rattlesnake plant cutting in a bright and warm location, but not in direct sunlight. Make sure to keep the plant away from cold drafts or air conditioning vents, which can dry out the leaves and roots. Keep the water level consistent and change the water every few days to help promote root growth.

Step 6: Wait for Roots to Form

It usually takes around two to four weeks for roots to form on the stem cutting. You'll know that roots have formed when the stem cutting starts to grow new leaves or when you can see roots growing out of the stem into the water. Once the roots are around two inches long, your rattlesnake plant cutting is ready to be transplanted into soil.

Step 7: Transplant the Cutting into Soil

Fill a pot with potting soil, making sure to leave enough room for the rattlesnake plant cutting's roots. Gently remove the stem cutting from the water and shake off any excess water. Place the cutting in the soil and pat it down gently, making sure the roots are covered. Water the plant thoroughly and put it in a bright location with indirect sunlight.

That's all there is to it! With a little patience and care, you can propagate rattlesnake plants in water and grow your collection.
