Callistemon: shrub and original flowering!

From a young clump bearing flowers in the shape of a bottle brush, callistemon becomes the known shrub also called bottle rinser. Planted in the right climate and in the right conditions, it could well grow into a majestic tree ten meters high and take the place of the "centerpiece" of your garden.

Usually cultivated in the cool soils of Australian wetlands, the shrub is very resistant, its foliage is persistent and it produces flowers of a scarlet red most often but sometimes yellow or even white of about fifteen centimeters, throughout the summer period.

In cold regions we prefer to grow it in a pot where it acclimatizes very well, and can adorn balconies and terraces to the delight of the eyes!

Either way, it's a tree that needs attention, you need to add well-decomposed compost 3 or 4 times a year, especially during the periods when it is flowering. In addition, it needs to be trimmed to find "pep". Otherwise, it is not uncommon for the shrub to slow down its flower production.

Sowing is possible, in spring, but more difficult and uncertain success.

When to cut?

• Summer, around August, on August wood.

How to make a cutting?

• Take a semi-woody cutting in summer

How to plant?

In the ground:

Prepare the soil:
• Work the soil to a depth of half a spade without turning over.
• Add potting soil.

Prepare the callistemon plants:
• define the positioning of the varieties with 60 cm of space or more, if you grow it as a shrub.
• Remove it from the pot, break up the root ball and scratch the soil to free the roots.
• Quickly soak in water.
• Set up.
• Fill in the spaces with the mixture of soil and soil from the garden.
• Tamp well.
• Do not bury the snare.
• Water to establish the shrub properly
• Keep the soil cool.

• From May to the first frosts

Care of the callistemon:

Some species:

Cal. citrinus: the best known of the species. It is also the most cultivated. The inflorescence is red, purple or pink;
Cal. citrinus "Splendens": Perfect for container culture
Cal. laevis: Long flowering
Cal. “Captain Cook” viminalis: variety with long leaves, its port is drooping, weeping. It is a not very hardy variety that offers red, purple, mauve or yellow blooms.

Callistemon goes well in the garden with

• Lady's mantles, geraniums, euphorbias ...

The soil in your garden should be rich, drained, cool or moist, and neutral or acidic.
The exposure should be sunny or partially shaded. For better flowering, choose a very sunny location.
There is little maintenance to be expected. The bottle-rinser is not very rustic and tolerates winter temperatures of the order of -5 ° C. It withstands wind, spray and, once properly installed, drought.
Perform a shaping pruning after flowering, preferably in summer. Regularly remove faded flowers to promote later blooms.

Flowering appears in abundance from autumn to spring (spring to summer in cold regions). It consists of red cylindrical inflorescences, in the shape of sprinkles. These flowers are lightly scented (lemon) and nectar-bearing.

With what types of products can pots and stakes be disinfected?
In any case, thank you for these good advice, strongly that the good weather returns to return to the garden.

You will use, after removing the excess soil, bleach diluted in water, in addition, on the wooden stake, you can apply Bordeaux mixture to prevent the development of fungi.


3) The cuttings of succulents

General technique

  1. Start by preparing your cuttings using a very sharp and disinfected blade (with methylated spirits, for example). Cut clean at its base.
  2. You can coat the cut with charcoal to prevent fungus from appearing.
  3. Let your cuttings dry for a few days (at least three) until they heal.
  4. Prepare a pot with a draining substrate made of sand, as succulents fear excess humidity. The ideal substrate consists of ¾ sand for ¼ potting soil. Also add a few spoons of charcoal powder.

Leaf cuttings

Leaf cuttings are the easiest to do. Take a leaf of your succulent (echeveria, cotyledon, sedum, graptopetalum, etc.) at its base, let it dry as explained above and plant the base of the leaf in the substrate. Place your cutting in full light. You will quickly see new leaves and roots appear at the end of the cutting.

The cuttings of the segments

Pachycereus, Cleistocactus, Senecios or even Crassulas are plants in the form of columns. The cuttings are therefore made on their segments. With a sharp blade, cut a segment of the stem including its end. Remember to wear gloves so you don't get stung with the cactus stings. Leave to dry for a few days then plant about 2 cm of the stem, taking care not to exceed this length at the risk of seeing the cutting rot.

Cacti require a lot of heat. To help the cutting, place half a bottle or sachet on top to recreate a greenhouse effect.

Cuttings in special cases

For suckers that are on ball cacti or for stems divided into sections, the method is slightly different. Indeed, we do not take directly from the mother plant, but we cut between two articles. This is the case with schlumbergeras or epiphyllum.

Another special case, the Kalanchoe daigremontiana. This plant produces seedlings on the edge of its leaves. They must then be picked meticulously and planted directly in the substrate mentioned above. In a few days, you will already see the first shoots!
