Ti plants (Cordyline spp.) lend a tropical feeling to homes, offices and shopping malls in temperate climates and make wonderful landscape plants for frost free areas. Hardy, long lived and generally pest resistant, these handsome ornamentals have much to recommend them. Ti cultivars are available in a staggering variety of leaf colors and forms. Fortunately, tis are also very easy to propagate by stem cuttings, so you can increase your supply and even share some with your friends.
Select a healthy stalk from a mature ti plant, at least ½" in diameter.
Remove the entire stalk from the base of the plant with the lopping shears. Make your cut as close as possible to the base of the parent plant, being careful to avoid damaging the crown. Cut the stalk at a 45 degree angle to hasten healing and be sure your loppers are clean and sharp to reduce the possibility of introducing pathogens.
Combine 1 part peat moss and 1 part sharp builder's sand in a five gallon bucket.
Use your hands to break up any lumps in the peat moss. Add half the recommended amount of time release fertilizer granules and mix well. Fill clean one gallon pots with the sand, peat and fertilize mixture.
Use the permanent marker to make a small mark on the stem of the ti cutting, three to four inches from the bottom. Repeat this up the stem, marking the entire cutting in three to four inch segments, until you get within eight inches of the base of the leaves.
Cut the stem into sections with the sharp pruning shears just above each mark. Make your cuts straight across and be sure you can still see the marks you made. Allow the stem segments to dry in a warm, well ventilated place. out of direct sunlight for two to three days.
Place each segment at a 45 degree angle into the soil mix in a one gallon pot with the marked end protruding slightly from the soil surface.
Water your pots until they drain from the bottom and place them in a warm, sheltered place in partial shade. Keep the soil evenly moist.
Move your ti plants into brighter light when they are about a foot tall.
