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.
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.
Go into the greenhouse with your cuttings and remaining supplies. Dip the bottom end of each cutting into a few drops of root hormone.
Place each cutting into a small pot filled with course sand, setting the cutting in the correct vertical position.
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.
Set your greenhouse humidifier to high humidity while the cuttings are rooting.
Remoisten the soil daily. After three weeks, gently tug on the stem of each plant; if there is resistance, then the plant is rooted.
