The green giant thuja is still a part of the public plant domain, meaning that anybody can propagate its cuttings. Over its lifetime, this stately conifer can reach a height of 60 feet, which makes it an excellent specimen for wind barriers and privacy hedging. When the tree goes dormant in the winter, Thuja provides high-quality cuttings. Any other time of year that you try to grow thuja cuttings, the results are not up to par.
Harvest thuja cuttings from robust trees to minimize the transmission of illness. Cut the sections into lengths of 6 to 8 inches. Take out the bottom four inches of the cuttings’ stems of plant.

Add potting soil to the growth tray. Use a pencil to make consistent holes in the ground. The holes prevent the rooting component from transferring to the soil’s surface. Wet the soil’s surface, but avoid letting it become too wet by spraying it with water.
Transfer two tablespoons of the rooting chemical onto a different plate to prevent contamination of the master supply. Insert the thuja cuttings into the holes after dipping them into the rooting compound. Tamping the dirt around the plant cuttings will help remove any air pockets. Cuttings are killed by bacteria that are bred in air pockets.

Place the growth tray on the heat pad in a well-ventilated area that is shielded from direct sunlight, then cover it with plastic. The thuja cuttings cannot live in direct sunshine because it produces too much heat. Before the cuttings have an opportunity to root, they will wilt.
Every day, take off the plastic for at least an hour to allow the developing tray to get some fresh air. Examine the tray for any signs of mold development and get rid of any dead or infected cuttings to prevent contamination from spreading throughout it.
Water the soil just when it seems dry, and avoid getting any water on the cuttings. When water accumulates on the leaves of conifers, it causes damage. Take good care of the cuttings until they begin to sprout new growth. The newly formed growth represents a growing root system.

When the roots start to show, take off the plastic and place the growing tray in direct sunshine. Till a robust root system forms, continue providing the thuja cuttings with care and water. After transplanting into separate containers, let the plant grow until it reaches the appropriate size. When the weather permits, move the newly planted thuja trees outside.
