The Archontophoenix Alexandrae. it is one of the most beautiful palm trees in the world, and one of the easiest to care for even more than its sister Archontophoenix cunninghamiana. From experience I can tell you that our protagonist adapts much better to direct sun if she gets used to it little by little, and it can also be grown in pots or small gardens.

So if you need a fast growing plant with a tropical look but able to withstand a few frosts, get one. In this article I will tell you what care you should provide.

Origin and characteristics

The fruits of the Archontophoenix alexandrae are red

The Archontophoenix Alexandrae. It is a native palm of Australia, specifically of the valleys and jungles of Queensland. It is popularly known as the Alexandra palm, Australian royal palm or Alexandro palm. It has a rapid growth, being able to exceed 20 meters in height. Its trunk is thin, ringed and slightly stepped, with a thickness of about 30cm.

The leaves are pinnate, 3-4 meters, greenish on the upper side and glaucous on the underside.. The flowers are grouped in interfoliar inflorescences, and there are female and male. The former have 3 staminodia, and the latter have 8-24 stamens and a pistil. It is monoecious (there are male and female specimens).

If you dare to get a copy, we recommend that you provide it with the following care:

Location

  • Outdoor: If it can be in a place where it has partial shade from young and sun as it grows, it will be great. It can also be kept in semi-shade throughout its life without problem.
  • Interior: in a room with plenty of natural light.

Irrigation

Frequent, especially in summer. You have to water 3-4 times a week during the hottest season, and every 3-4 days the rest of the year. If you are going to have it in a pot, put a plate under it, it will appreciate it 😉.

Earth

  • Flower pot: universal culture substrate mixed with 30% perlite.
  • the garden: it must be fertile, with good drainage.

Subscriber

From early spring to late summer must be paid to the Archontophoenix Alexandrae. with specific fertilizers for palm trees following the indications specified on the product packaging. But to make it really good, I advise paying it from time to time -for example, in alternate months- with ecological fertilizers.

Multiplication

It multiplies by seeds in spring. The way to proceed is as follows:

  1. The first thing to do is put the seeds in a glass of water for 24 hours. Those that remain floating will be discarded since they are unviable.
  2. Then a 10,5cm diameter pot is filled with universal growing medium and watered.
  3. Afterwards, a maximum of 2 seeds are placed in the pot, and they are covered with a thin layer of substrate so that they are not exposed directly to the sun.
  4. Finally, the pot is placed near a source of heat or outside in full sun.

Keeping the substrate moist will germinate in 2 months3 maximum.

Planting or transplanting time

In springwhen the risk of frost has passed. If it is potted, you will need a transplant every 2 years.

Pests

Red palm weevil, a potentially deadly pest for palm trees

It is a fairly resistant palm tree, but if the growing conditions are not suitable, the following pests can attack it:

  • Mealybugs: they can be cottony, or limpet type. In any case, they are parasites that suck the sap from the leaves, especially the most tender ones. They are eliminated with an anti-mealybug insecticide following the indications specified on the package.
  • Red weevil: it is a weevil (a type of beetle but thinner) whose larvae dig galleries in the trunk, weakening the palm tree. It is not very frequent in Archontophoenix, but if you live in an area where this pest has already “settled”, give it preventive treatments with the remedies indicated in this article.
  • he is the archon: it is a moth whose larvae feed on the heart of the palm tree, from which the new leaves come out. When these blades are opened, it is easy to see a series of fan-shaped holes produced by them. Like the weevil, it is not often seen in A. alexandraebut if there are in the area you have to do preventive treatments with the remedies indicated in the link.

Rusticity

Withstands frosts up to -4ºC if she is an adult. While you are young you need some protection.
