Origins and peculiarities of cordyline
Native to the Southeast Pacific, the cordyline is a plant that was discovered in the 18th century, during an explorer James Cook's trip to New Zealand! Its name comes from the Greek kordulê, clubbed in French, because of the thickness of its very vivacious underground stem.
Cordyline is a ornamental plant belonging to the Agavaceae family, just like yucca (there is also a little family resemblance between these two!); with its superb decorative foliage and the pretty pink or white flowers that the plants produce at maturity, the cordyline is perfect for bringing a nice touch of exoticism, whether in a garden or indoors.
Good to know : the cordylines are somewhat lazy, and all species of the genus show slow growth. If you grow it in a pot or in a planter, never expect your cordyline to reach a height of more than 6 m, as it can be the case in the wild. It is not uncommon that even when mature, a cordyline grown in a pot never flowers. Fortunately, its foliage is so beautiful that even without flowers, the cordyline remains a majestic plant!
If it is possible to grow cordylines in the open ground in a garden, these plants from the Southern hemisphere do not tolerate harsh winters: if you do not live in a mild or temperate region (Southeast of the France but also on the Brittany or Normandy coast under the influence of an oceanic climate and less ferocious winters), it is preferable to cultivate your cordyline in a pot to either leave it at home (this plant is perfect for decorating an entry , a living room or a bedroom), either to install it on a balcony or terrace; on the condition of returning it at the end of the summer!
If you want plant your cordyline in the open ground, do it rather in the spring (from May until September).
What technique should be used to reproduce cordyline?
For multiply the cordyline, the gardener has the choice between several methods such as sowing, cutting or rejecting. The last two methods are the quickest and are carried out during the spring period.
If you are a beginner, choose the stem cuttings method without hesitation. All cuttings must be placed in a warm place (constant temperature of 20 ° C) with misters so that the atmosphere is conducive to the development of roots. The first results are visible ten weeks later.
When living outdoors, it requires less maintenance. Gardeners recommend keeping an annual calendar for:
- Feed the plant a good liquid fertilizer once every 12 days.
- Feed the foot with compost on spring day and fall day.
- Mulch the foot at the arrival of low temperatures.
Cutting level, the plant does not need to receive specific care. On the other hand, it is possible and strongly advised to remove dead leaves as you go. In the event that it lives in a pot, it will be necessary to think of watering it regularly. The frequency of watering is reduced in winter (twice a week).
Cordyline pests and diseases
If outside cordylines are rather resistant and not very prone to diseases, plants grown indoors in pots are a little more fragile. Fortunately, if you look at their leaves, you can easily act. So :
- If their leaves start to stain, you have too heavy a hand on the watering.
- If the leaves of your cordyline become tarnished, move the plant to a brighter place.
- If the leaves start to fall, the soil is too full of water: stop watering and allow it to dry.
- If the new shoots are not growing, the plant is not being fed enough: add liquid fertilizer.
