cabbage palm plant Shop 'Cordyline australis – Cabbage Tree' Care and Info

The Cordyline australis has several other common names such as Ti Kouka, Torquay Palm, New Zealand Cabbage tree, Dracaena australis, mountain cabbage tree, forest cabbage tree, and Cabbage Palm tree. These names reflect its association with traditional Maori culture and its resemblance to palm trees. However, it’s not a cabbage or a palm, and it doesn’t come from Torquay. 

The overall size of the tree can vary depending on its growing conditions and the specific variety. It's important to consider the available space when planting a Cordyline australis, as it can spread out and become quite substantial. 

The flowers of Cordyline australis bloom in the mid-spring or early summer with large, fragrant clusters of creamy white flowers. These flowers attract bees and other pollinators, adding to the tree's appeal. After flowering, small, berry-like fruits may appear, which are often enjoyed by birds. 

The Cabbage Tree can be propagated through various methods, including seed germination and stem cuttings. Growing from seeds requires patience, as it can take a while for the seeds to germinate. Stem cuttings, on the other hand, can be a quicker and more reliable method. Simply take a cutting from the main stem and remove the lower leaves. 

In New Zealand, the Cordyline Australis, or Cabbage Tree, is protected under the Resource Management Act. It means that you generally need permission to cut them down. Sudden declines in Cordyline cabbage trees in farmland and open areas are common, but natural forest patches are doing well. There is no cure for sudden decline, so planting more young cabbage trees is crucial to replace dying populations. 

Watering Needs 

When it comes to watering, it's important to let the top inch or so of the soil dry out between waterings. The Cabbage Tree is a drought-tolerant plant that doesn't need frequent watering and is better to be underwater than overwatered. Stick your finger into the soil and if it feels dry at that depth, then it's time to water. Be sure to water the plant thoroughly, allowing the water to soak into the root zone. 

In the spring and summer, during the growing season, which is typically spring and summer, you can water the Cabbage Tree once every 7-10 days. However, during the cooler months or when the plant is dormant, you can reduce the frequency and water it every 2-3 weeks. 

Remember, it's always better to underwater than to overwater. Overwatering can lead to root rot and other issues, so it's important to let the soil dry out before watering again. 

Light Requirements 

When growing the Cordyline plants indoors, they thrive in bright, indirect light. Place it near a window where it can receive plenty of sunlight, but make sure to avoid direct sunlight, as it can scorch the leaves. If you notice the leaves turning pale or yellow, it might be an indication that it needs more light. Consider supplementing with artificial grow lights if you don't have access to sufficient natural light indoors. 

For outdoor cultivation, the Cabbage Tree prefers full sun to partial shade. It loves soaking up the sun's rays and will grow best in a spot that receives at least 6 hours of direct sunlight per day. However, it can also tolerate some light shade elsewhere, especially in hotter climates where it might benefit from protection against intense afternoon sun. Just make sure it still gets enough light to thrive. 

Remember, finding the right balance of light is important for the health and growth of the Cordyline Cabbage Tree. Too little light can result in leggy growth and reduced vigor, while too much direct sunlight can cause leaf burn. Observing the plant's response and adjusting its location accordingly will help you provide the optimal lighting conditions. 

Optimal Soil & Fertilizer 

The Cordyline australis favors very airy, sandy well-drained soil. Planting them in ordinary soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized succulent potting mix, opens in a new tab that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your succulent to thrive. 

The Cabbage tree plant doesn't have high fertilizer requirements, but a little boost can help it thrive. Once a year in the spring, you can fertilize it with a balanced, slow-release fertilizer, such as a 5-10-5 formula. Be careful not to over-fertilize, as this can cause salt buildup and damage the plant. 

When applying fertilizer, make sure to water the plant before and after to prevent any potential burning of the roots. Additionally, avoid getting fertilizer on the leaves, as it can cause leaf burn. Remember to follow the instructions on the fertilizer packaging for best results. By providing well-draining soil and occasional fertilization, you'll help ensure that your Cordyline cabbage tree has the nutrients it needs to grow healthy and strong. 

Hardiness Zone & More 

When grown indoors, it can tolerate temperatures between 60°F to 75°F, which makes it perfect for most indoor environments. As for humidity, it prefers moderate to high humidity levels. If the air in your home is dry, you can increase humidity by using a humidifier or placing the plant on a pebble tray filled with water. 

For outdoor cultivation, the Cordyline australis is well-suited in USDA hardiness zones 9 to 11. It can tolerate a wide range of temperatures, from about 20°F to 100°F. However, it is important to note that prolonged exposure to freezing temperatures can damage or kill the plant. If you live in a colder zone, consider growing the Cabbage Tree in containers that can be brought indoors during the winter months. In terms of humidity, it can adapt to various levels, but it generally prefers moderate humidity.

Remember, these guidelines are based on USDA hardiness zones and general temperature and humidity preferences. Observing your specific growing conditions and making adjustments accordingly will help ensure the best care for your Cabbage Tree.
