The Haworthias cooperi, are a very diverse group of leafy succulents that form rosettes.
They are originally from South Africa, more specifically from Namibia, Mozambique, Lesotho and Swaziland. This is one of the more than 100 species of haworthias, which exist.
The species originates in the commented summer rain areas of South Africa.
They are succulents of the family of the Xanthorrhoeaceae, perennial that form rosettes without stems, from small, from 5 cm to 7 cm, to the largest ones of about 12 cm in diameter.
There are different varieties:
- Haworthia cooperi var. cooperi
- Haworthia cooperi var. dielsiana
- Haworthia cooperi var. doldii
- Haworthia cooperi var. gordoniana
- Haworthia cooperi var leightonii
- Haworthia cooperi var. pilifera
- Haworthia cooperi var. truncata
- Haworthia cooperi var. venusta
Description of Haworthias cooperi.
The Haworthia cooperi is a crasa or succulent plant not cactaceous perennifolia native to South Africa. It was described by John Gilbert Baker and published in Refug. Bot. 4 in the year 1870. It is characterized by forming rosettes of 30 to 40 oblong-lanceolate leaves, of a light green color, with the flat and the convex underside. It produces floral stems about 20cm high at the end of which white and very small flowers of less than 1cm sprout.
Its rate of growth is rather slow; in fact, it only grows a little fast since the seed germinates until it acquires a diameter of 4-5 cm. Then it does not grow much more in width, although you will see that it has a tendency to shoot.
Its leaves, usually about 30 or 40 in the form of a rosette, are thick, turgid, like stubby and ending in an acute manner and are usually blue-green or even orange in color, when they suffer from excessive sunlight.
According to the species in question, the leaves of these succulents may be covered with little pellets or small white warts.
The tips of the leaves have an attractive pattern, with marked transition zones, with long alternating needles with translucent and pigmented areas.
These Haworthias with tips of translucent leaves, grow partially buried in the habitat, with only the tips of the leaves exposed to daylight.
It is a very beautiful, attractive and very decorative plant. Better, if we accompany it with an envelope porcelain pot, to match the decoration of the home or the color our cooperi.
Description of Haworthia Cooperi flowers .
It forms dense clusters when they bloom, being the flowers simple and white. They are born from the inflorescence.
It blooms from spring to summer, has a peduncle of simple inflorescences, about 30 cm long.
The flowers are tubular, about 10 millimeters long and about 8 millimeters wide. The petals and sepals are attached for most of the length of the floral tube.
The petals and sepals strongly reflexes, are greenish-blueish white, with medium stripes of green to greenish brown. While nobody grows these plants for their flowers.
The flowers of the Haworthias, even in their different species, are very similar. However, the leaves are usually very different, each one having a characteristic aspect, typical of its species.
Lighting and ideal temperature for its development
Haworthias cooperi, are hard plants and do not require much care, so it is easy to grow and maintain.
It must be in well-lit areas, intense light, natural light but without direct sunlight. They are good areas of good ventilation, not drafts, preventing them from low temperatures.
We will observe by the color of the leaves, if the plant is suffering and what is due. If the leaves of the Haworthia cooperi present a pale or yellowish color, it denotes excess sun exposure.
They usually do not tolerate temperatures well below 5ºC, in winter. Try not to fall below 10ºC in winter.
For the good development and growth of the plant, the ideal would be that it was always within a warm temperature.
How to water the Haworthia cooperi
It should be irrigated abundantly and frequently, in the spring and summer months. Always avoid the dreaded floods, so only water when the substrate is dry.
Irrigation will be reduced in autumn, until winter. In this time, almost eliminate the irrigation as such and just keep the substrate moist.
Try not to accumulate irrigation water in the rosettes of the plant.
How to fertilize, transplant and prune this plant correctly
To have healthy and well fed the plant, it must be fertilized in spring and summer, once a month or every 20 days and use a liquid fertilizer, typical of succulents, added to the irrigation water.
In autumn and winter, do not supply any.
For the haworthia cooperi transplant, make sure the container has adequate drainage.
Good idea is to add a layer of gravel to the bottom, to reduce the action of absorbing the soil.
Does not require pruning. Just remove the leaves that are dry.
The reproduction of the Haworthia
The Haworthia cooperi is multiplied by seeds and suckers in spring and summer. Let’s see how to proceed in each case:
The step by step to follow is the following:
- First, a tray must be filled – it must be at least 20 cm in diameter by 5 cm in height, with holes – with black peat mixed with 50% river sand.
- Then, it should be watered consciously.
- The next step is to spread the seeds, making sure they are not piled up.
- Next, they are covered with a thin layer of black peat.
- Finally, the tray is placed in a bright place but not in full sun.
They will germinate in 2-3 weeks.
Hatch-lings can be separated from the mother plant when they are easily manipulated, about 3-4 cm. Then they are planted in individual pots, and ready
Pests that can affect our Cooperi
The Haworthia cooperi, are usually free of pests.
The main pest that attacks the cooperi is the cottony scale. Combat this pest with suitable commercial insecticides.
However, in tropical climates, its main enemy is the bacterium Erwinia carotovora , a bacterium that is introduced into the plant by the root system and if left to act, kills the plant in a few weeks. A good fungicide to use is reliant .
If infection of the bacteria is detected, dig out the roots of the plant completely, clean or eliminate the most infected parts.
It should be applied on the wounds of the bacteria, a knife or razor to red hot, to cauterize the wounds of the roots.
In addition, introduce the roots of the plant, for a few minutes, in a chlorine solution, so that we ensure the disinfection of them.
