Rosettendickblatt, Aeonium arboreum - care and propagation

The Content Of The Article:

For a long time, the small-sized leaf ornamental plant with its impressive flowers has also found its way into our living rooms. Aeonium arboreum, also called Rosettendickblatt, is one of the succulent plants, which are generally classified as very easy to maintain, provided that a few simple rules are met.
In late winter appear on Rosettendickblatt in older plants up to 30 centimeters high, yellow inflorescences. This is all the more impressive because the plant itself is usually knee-high. In summer, the plant is also suitable as a container plant for the terrace or the balcony. However, the prerequisite is that it is as bright as possible and protected from heavy downpours, because waterlogging does not tolerate the plant. But she loves the sun all the more.

  • botanical name: Aeoniumarboreum
  • belongs to the family of the thick-leafed plants, genus Aeonium
  • stem-forming succulent plant (subshrubs)
  • Leaves: green, yellowish or reddish, rosette-shaped
  • Blossom: ovate inflorescence with small, yellow flowers (January / February)
  • Growth height: 60-100 centimeters
  • Leaf and flower decoration plant
  • evergreen
Species and occurrence
Aeonium arboreum is native to the Canary Islands, but has since settled in the Mediterranean. There, the plant grows as a little branched subshrub up to a height of about two meters and a width of one to three meters. With us in the room a Rosettendickblatt is rarely higher than about 60-80 centimeters. Meanwhile, a number of crops have been bred. Known breeding forms of Aeonium arboreum are:
  • atropurpurpureum (Schwarzkopf, Nigrum, Zwartkop): dark purple leaf rosette
  • holochrysum: light green leaves
  • rubrolineatum: reddish veining with green leaf base
  • albovariegatum: white-green variegated leaves
Aeonium arboreum is used to a lot of sunshine from her home country. Therefore, it should be placed on a bright window, the south window is not a problem. In summer, the Rosettendickblatt feels in the open air very well. Anyone who has a balcony or patio does something really good for his plant to put them in the fresh air for a few weeks or months. That makes them more resistant to winter. Outdoors, a rose leaf should be protected from rain.
  • Light requirement: very high (bright to full sun)
  • also tolerates strong heat well
  • protect from heavy rain
Tip: Red-leaved and variegated variants lose their color when they are too dark. The color returns when they regain enough sunlight.
In nature, a rosette inflorescence grows on nutrient-poor soils that are well permeable to water. Normal potting soil is not very suitable for succulents. The best is a mixture of cactus or low-nutrient potting soil with a very high content of sand and clay or lava granules.
  • 50% cactus clay, 25% quartz sand, 25% pumice (or expanded clay)
  • 40% cultivation soil, 20% quartz sand, 20% lava granules, 20% clay granules
  • 20% compost soil, 20% garden soil, 25% quartz sand, 25% lava or clay granules
to water
Aeonium arboreum is one of the succulents, a group of plants that can store water in their home country due to prolonged dry spells. Therefore, to plant the plant almost completely would be just as wrong as keeping it too moist. Waterlogging does not tolerate succulents like Aeonium arboreum. The roots begin to rot quickly and the pretty plant is then usually beyond saving. The Rosettendickblatt wants to be moderately poured in the spring and summer months, in winter very little if at all, depending on the location. The cooler the plant is, the less must be poured. Starting in March, the casting will begin again slowly. The root ball should always be watered very penetrating, so that the irrigation water runs down out of the holes in the pot again. Better still is a dip of the pot, in which the planter is placed in a tub of water to about ¾ for a maximum of ten minutes. Important: Drain the root ball thoroughly and remove excess water from the saucer.
Tip: For control, an untreated wooden stick can be put into the ground (at least 5 cm deep). If this is completely dry when pulling out, it must be poured.
The substrate of Aeonium arboreum is ideally low in humus. At the same time, however, this means that nutrients must be supplied to the rosette thicket during the growing season in spring and summer. Between April and the beginning of August, fertilizers are used for succulents or cacti about every two to three weeks.
To cut
If a rose petal grows too sparse, you can cut back the stems without hesitation. The best way to start with a drive and kappt at the desired location.So you can see how the plant coped with the pruning. If new branches form, the other shoots are gradually cut back. After flowering, the rosettes die off and then have to be cut as well.
Aeonium arboreum is not particularly vigorous, so it is sufficient to transplant the plant into a larger pot every three years. If the Rosettendickblatt is poured with calcareous water, the earth should be carefully removed every year and replaced with new ones.
  • Time: March to April (after flowering)
  • Carefully pull the plant out of the pot
  • take it as deep as possible, as it breaks easily
  • The roots do not come off the pot, cut along the edge with a sharp knife
  • carefully remove old soil
  • first fill drainage layer
  • Put plant in special succulent substrate
  • put in a little less sunny over the next two weeks
Tip: Since injured roots rot fast, the freshly repotted rose petal should not be cast in the next two weeks.
An increase is possible by head and leaf cuttings as well as by sowing of seeds. Growing from seeds is only for the patient gardener, as it takes a long time for a handsome plant to grow from it.
For a head cuttler, a whole rosette is cut including a 5-10 centimeter long piece of trunk. Leaf cuttings, on the other hand, are obtained from a single leaf that is plucked or cut as deep as possible out of the rosette. Both types of cuttings can be placed in moist, very sand-containing substrate and set up bright, but without direct sunlight. In order to prevent mold growth, the following method has proven itself:
  • Time: spring
  • Material: commercially available fine-pored household sponge, coasters
  • cut small notches with scissors or knife into the sponge
  • Insert a maximum of one third of leaf cuttings
  • Put sponge on coaster
  • water so much that there is always about one centimeter of water in the saucer
In leaf cuttings grows from the leaf a completely new plant. If this is about one centimeter in size, it can be used in special substrate. The following summer, the young plant should not be exposed to the blazing midday sun.
Frequently, seeds for Aeonium arboreum are also commercially available. For sowing, the seeds need not be pretreated, but can be applied directly to a special substrate.
  • Time: spring
  • Plastic pot, mini greenhouse, planter
  • Temperature: 23-28 degrees, not colder than 20 degrees at night
  • Substrate: Cat litter (non-clumping), perlite, pumice or quartz sand
  • Place seeds on the substrate, lightly press
  • do not cover with substrate
  • Place plastic pot in freezer bag
  • add enough water (from below) to leave about 1 cm of water after soaking
  • close airtight
  • set up bright (no direct sun)
If the seedlings have grown a few centimeters, they can be planted in individual pots.
A Rosettendickblatt prefers cool and very bright in the cold season. Plants that have spent the summer outdoors should be brought back to the house by mid-September at the latest, as they can not tolerate frost or damp, cold weather. A good place for wintering:
  • cool, but frost-free
  • Temperature: 8 to 10 degrees (at least 5 degrees)
  • Stair-protected, bright staircase
  • conservatory
  • do not or only very slowly pour
Do not worry if the dark purple Nigrum loses its color and turns green during the winter months. That's because of the lack of light. From spring, the coloring returns by itself.
Diseases and pests
If a rose petal is over-molded, it rots its roots. Otherwise, the plant is very robust and is only occasionally infected with warm heating air in the winter of sucking insects.
If you are looking for an easy-care and robust plant for your home, you will be well served with the rosette bubble. Brightly set up all year round, the plant regularly needs water and a little fertilizer in summer. In winter, it can be more or less left to itself in a cool, bright place. Good care rewards the succulent with large yellow inflorescences in February.
