Propagation of Greenhouse Plants


Greenhouses are an ideal location for propagating and growing a variety of plants. The most advantageous form of propagation used in a greenhouse is known as propagation by stem cutting. This form of propagation takes a young stem cut off of a plant within the greenhouse and trains the stem to produce roots and become its own plant.

Step 1

Take some fresh cuttings from a healthy plant and place them in a plastic bag. Moisten a paper towel and place it inside the bag with the cuttings. Keep the cuttings in the bag until you are ready to root them.

Step 2

Go into the greenhouse with your cuttings and remaining supplies. Dip the bottom end of each cutting into a few drops of root hormone.

Step 3

Place each cutting into a small pot filled with course sand, setting the cutting in the correct vertical position.

Step 4

Set the pot in a large pan or basin with 2 inches of water and let the soil soak up water until the top of the soil is moist. Remove the post from the water and set them on a stable surface in your greenhouse.

Step 5

Set your greenhouse humidifier to high humidity while the cuttings are rooting.

Step 6

Remoisten the soil daily. After three weeks, gently tug on the stem of each plant; if there is resistance, then the plant is rooted.
