The dogwood is a small-growing tree or large shrub with multiple branches of a shirt trunk. The tree reaches a height of 15 feet and is available in a flowering variety that blossoms in the spring. Propagate dogwood trees by taking softwood cuttings in late spring or semi-hardwood cuttings in mid-summer. Softwood cuttings are new growth that is starting to firm and mature. Semi-hardwood cuttings are growth with mature-size leaves and a firm texture.
Wash all cutting and propagation tools in a solution of 1 part bleach and 9 parts water. Rinse the tools well and let them dry.
Cut a 6-inch softwood or semi-hardwood stem from the flowering dogwood with a sharp knife. Take cuttings from current year growth found on the upper area of the flowering dogwood. Place the stems in a wet paper towel to prevent them from drying.
Mix a rooting medium for the dogwood cuttings by combining equal portions of course sand, sterile peat moss and perlite. Moisten the rooting medium mixture with water.
Cut off all leaves on the bottom half of the dogwood stem. Cut in half the remaining large leaves to conserve space and moisture in the rooting tray.
Fill a rooting tray with moist rooting medium. Dip the cut end of the dogwood stem into the rooting hormone. Stick the dogwood stem halfway into the rooting medium and firm the soil to hold in place.
Water the cuttings lightly. Cover the tray with a clear plastic bag to create a humid environment. Place the dogwood cuttings in warm location with indirect sunlight or under growing lights.
Open the plastic bag to refresh the air and to mist the dogwood cuttings each day. Lightly spray the cuttings with a liquid fungicide diluted to half strength once a week.
Verify that roots have formed by gently tugging on the dogwood cuttings to see if there is resistance after three to four weeks of growth. Transplant the cuttings to individual containers once the roots reach a length of at least 1 inch.
