Dogwood Trees are a small tree with a short, branched trunk that reaches a height of approximately 15 feet. Flowering varieties produce white or pink flowers for two to three weeks during spring. The best choice for propagation is through softwood cuttings, as they are taken in spring when new growth is at the maximum level. Softwood cuttings will begin to root in three to six weeks after propagating.
Cut 4- to 6-inch softwood cuttings in spring when young growth is present on the tree. Cut the branches with a sharp pruner 1/8 inch below the leaf joint. Place the cutting in a bucket of water.
Mix a container of rooting compost that is comprised of equal parts sharp sand, peat moss and perlite. Moisten the mixture with water.
Remove all leaves from the lower half of the softwood cuttings using sharp scissors or a pruner.
Dip the cut ends into rooting hormone. Punch a hole into the container rooting compost with a pencil. Insert the cut ends into the compost and gently push the media around the cutting to hold in place.
Water the cuttings gently and place them in a bright area or under grow lights. Place a clear plastic covering over the cuttings to retain moisture.
Mist the cuttings every day with water. Spray the cuttings once a week with a diluted liquid fungicide.
Harden rooted cuttings by reducing the amount of water misted and opening the plastic covering each day for one week. Gradually lengthen the time the time the covering is open over this time period.
Transplant the cuttings to individual containers once they are hardened. Continue to grow the cuttings until they are large enough for outdoor planting.
