Cordyline
Cordyline, commonly referred to as ti plants, typically originate from Australasia and can reach heights up to 10 ft. There are over 20 species of Cordyline, many of which have distinctive foliage and variegated colors with shades of green, yellow, white, pink, red, and even purple! The leaves may also vary in shape from long, thin, spiky leaves to round, short, and wide leaves. Cordyline is commonly grown as an ornamental, not only for its beautiful foliage, but for its interesting year-round growth patterns and vibrant colors.
Cordyline likes to remain moist but not saturated to prevent root rot. Water the plant when the top layer of soil feels dry to the touch. During the warmer months, water as often as necessary to keep the soil evenly moist, as long as the plant does not sit in water. In the winter, reduce waterings and allow the soil to dry slightly between waterings.
Cordyline thrive in bright, indirect light but can tolerate low to medium light. They prefer further away placement from the window and not overly bright conditions that may cause stress and sunburn. Lighting at least 6 hours of indirect sunlight per day is ideal, as too much light can cause yellow or pale leaves.
Cordyline prefers temperatures between 65-80°F (18-27°C) during the growing season. In winter, keep temperatures above 55°F (13°C) for ideal growth. Winter temperatures below freezing can damage the plant and cause wilting of the leaves.
Cordyline is more drought-tolerant than other houseplants, however, for optimal health, higher humidity in the air is beneficial. If the air is too dry, place the plant in a location with adequate airflow away from heating and cooling vents or simply mist the leaves with water occasionally.
Cordyline prefer a well-draining soil mix made up of peat moss, perlite, and vermiculite. Add a balanced mixture of organic and inorganic nutrients and soil amendments for optimal growth. The soil should have a pH range of 5.5-7.5, and the temperature should be kept between 65-80°F (18-27°C ).
Cordyline can benefit from regular fertilization throughout the season, especially in the summer when it is actively growing. A slow-release or all-purpose 12-4-8 fertilizer formulated for houseplants is best. Avoid over-fertilizing the plant as too many nutrients can lead to excessive leaf death.
Cordyline is prone to common houseplant pests such as aphids, mealybugs, and mites. Check the plant carefully for small spots, ants, or any other signs of pests. Remove pests and dispose of any pest-infested or dead leaves that may be harming the plant. To prevent further pests, use water to clean the leaves and soil, and avoid touching the plant with unwashed hands. Keeping the leaves dry when watering, as well as keeping the area around the plant clean of debris for optimal health.
Cordyline typically need to be repotted every 1-2 years. When potted in the correct soil and in the correct temperature and light conditions, the plant won’t outgrow its pot as quickly. Reaction to its environment will be slower as well due to its slower growth rate. Generally, repotting should be done in the early spring or summer when the weather is warm and the roots of the plant are more vibrant.
When necessary, pruning can help Cordyline maintain its structural shape, gently cut off any dead or diseased leaves. Pruning back leaves that have become too long or have become unsightly can also be done safely, as long as you follow the correct pruning techniques. Prune away leaves that are wilting, discoloring, or have spots. Prune in early spring, making sure not to prune more than one-third of the plant; more than this could shock the plant and make it vulnerable to disease.
Placing a layer of mulch around the plant can help keep the soil moist and warm, as well as reduce the growth of weeds. A layer of peat moss, pine straw, or wood chips work well, and should be about 2-3 inches thick.
Propagating Cordyline is possible through stem cuttings. Cut a stem below the leaf nodes or the base and plant in moist potting soil or a water-filled tray. Keep the soil moist as the plant develops roots but avoid overwatering. Transfer the stem cutting from the tray or potting soil to a larger pot once the stems appear healthy.
Since tall Cordyline can have heavy, stiff stems, a supporting stake or pole may be necessary for larger plants to stabilize the plant. Tie the stem to the stake with soft garden ties to encourage it to grow upright, and avoid damaging the plant by using ties that are too tight.
As with most tropical plants, Cordyline will experience a rest period in the winter. As the days become shorter and the temperatures become cooler, the plant will become dormant and stop producing new growth. During this period, reduce watering and feeding and refrain from moving the plant.
Cordyline is not toxic to pets if ingested. However, due to its sharp leaves, it is not recommended that animals interact with or around them as they could sustain injury.
