Preparing the Greenhouse for Propagation

When propagating Chocolate Soldier (Kalanchoe tomentosa) in a greenhouse, it is essential to set up a suitable environment to ensure successful growth. Here are some steps to prepare the greenhouse for propagation:

Cleaning and sanitizing the greenhouse

Before starting the propagation process, it is crucial to clean and sanitize the greenhouse to prevent the spread of diseases and pests. Remove any debris, old plant material, and weeds from the greenhouse. Disinfect all surfaces, pots, and tools with a solution of water and bleach to eliminate any harmful pathogens.

Setting up the propagation area

Designate a specific area in the greenhouse for propagating Chocolate Soldier plants. Arrange propagation trays or pots filled with well-draining soil or a suitable propagation medium. Make sure the area receives adequate sunlight or artificial light for optimal growth. Provide proper ventilation to prevent the buildup of humidity and reduce the risk of fungal diseases.

Maintaining the ideal temperature and humidity

Maintaining the ideal temperature and humidity levels is crucial for successful propagation of Chocolate Soldier plants. Keep the greenhouse temperature between 65-75°F during the day and above 50°F at night. Use a thermometer and humidistat to monitor the temperature and humidity levels regularly. Consider using a misting system or humidity tray to increase humidity levels if necessary.

By following these steps to prepare the greenhouse for propagating Chocolate Soldier plants, you can create a conducive environment for healthy growth and propagation.

Selecting and Preparing Chocolate Soldier Cuttings

Choosing healthy parent plants

When selecting parent plants to take cuttings from, it is important to choose healthy specimens that show no signs of disease or pest infestation. Look for plants with strong, thick stems and vibrant, green leaves.

Taking appropriate cuttings

To take cuttings from a Chocolate Soldier plant, use a sharp, clean pair of scissors or pruning shears to cut a 3-4 inch piece of stem just below a leaf node. Make sure to choose a stem that is healthy and free from any damage.

Treating cuttings with rooting hormone

After taking the cuttings, dip the cut end of each stem into a rooting hormone powder. This will help stimulate root growth and increase the chances of successful propagation. Make sure to follow the instructions on the rooting hormone package for best results.

Propagating Chocolate Soldier Cuttings

To propagate Chocolate Soldier (Kalanchoe tomentosa) in a greenhouse, follow these step-by-step instructions:

Planting the cuttings in suitable soil mix

  • Choose a well-draining soil mix that is light and airy, such as a mix of perlite, sand, and peat moss.
  • Prepare small pots or containers filled with the soil mix.
  • Take cuttings from healthy Chocolate Soldier plants, making sure they have at least a couple of leaves.
  • Dip the cut end of the cutting in rooting hormone to encourage root growth.
  • Plant the cuttings in the soil mix, making sure the bottom leaves are touching the soil.

Providing proper watering and light conditions

  • Water the cuttings lightly to keep the soil slightly moist but not soggy.
  • Place the pots in a location with bright, indirect light. Avoid direct sunlight, as it can scorch the delicate leaves of the Chocolate Soldier.
  • Maintain a consistent temperature of around 70-75°F (21-24°C) for optimal growth.

Monitoring for signs of growth and roots

  • Check the cuttings regularly for signs of new growth, such as the emergence of new leaves.
  • Gently tug on the cutting to check for resistance, which indicates that roots are forming.
  • Once roots have developed, the cutting can be transplanted into a larger pot with regular potting soil.

By following these steps and providing the proper care, you can successfully propagate Chocolate Soldier cuttings in a greenhouse.


In conclusion, propagating Chocolate Soldier plants in a greenhouse can be a rewarding and enjoyable experience for any plant enthusiast. By following the step-by-step guide outlined in this article, you can successfully propagate and grow your own Kalanchoe tomentosa plants with ease. Remember to provide the right conditions, such as proper lighting, temperature, and soil moisture, to ensure the health and growth of your plants. With a little patience and care, you can enjoy beautiful, fuzzy Chocolate Soldier plants thriving in your greenhouse in no time.
