Their variety is admired, and in today's article we will talk about the Garris cactus (Eriocereus jusbertii) and all the nuances of creating favorable conditions for its growth and development.
Botanical description and main types
The species is attributed to bushy and tree-like representatives of the branching cactus. It has thin straight stems, painted in dark or gray-green color. The cactus grows in height up to 5 meters, diameter - from 4 to 6 cm. The ribs are low and flat, their number depends on the type and ranges from 5 to 12. The spines are needle-shaped, white with black ends, 1-3 cm long. It blooms with white large flowers.
There are many types of Garrisia:

Care after purchase
After the plant has got into the house, it is necessary to hold some activities, thanks to which it will fully grow and develop.
Quarantine
When choosing a flower in a store, it is important to inspect it for a variety of stains and damage that may indicate any diseases. Choosing a healthy plant, you need to re-examine the house and wash its surface with warm water or various insecticidal or fungicidal preparations. After which you should put the Eriozereus apart from other cacti for two weeks, carefully watching him. In this way, unwanted infections of neighboring plants can be prevented, as well as timely treatment of the new specimen.
Transfer
After successfully transferred quarantine, it is better to transplant the flower, creating the necessary properties for the germination of Eriotsereusa:
- slightly acid soil;
- free pot.
In the future, this procedure is carried out quite often, as the plant grows. The soil is chosen nutrient, heavy, having a high throughput.
For this purpose it is necessary to mix the components in the following ratio:
- leaf humus - 40%;
- clay earth - 40%;
- coarse sand - 20%.
Important! It is necessary to stop watering three days before transplanting and continue it after 7 days.
It is also worth a responsible approach to the choice of the pot: it must be either plastic or ceramic, the main thing is the presence of drainage holes, which will exclude the stagnation of moisture. Garrisia loves space, so the pot must be larger than the previous one, but for the plant to cover half of its surface.
Further care
For plants it is important to choose the right location, as well as create optimal parameters of the microclimate.
Choosing a place
Garrisia needs fresh air, so in the warm season it can be placed on the balcony or in the garden. With the onset of cold weather, it is important not to forget about airing the room, during which the pot is removed from the window sill in order to avoid the negative effect of drafts. When placing the pot should take into account the need for plants in bright diffused light, but in no case should not put the cactus under direct sunlight, which can burn the surface of the flower. 
Temperature conditions
In summer, the temperature is kept within + 20 ... + 25 ° С, while in winter its indicator should be no lower than + 10 ° С.
Air humidity
The optimal rate is in the range of 50-55%, with an increase in the flower can begin to hurt. In hot weather, it is recommended to spray the cactus with warm water.
Watering
The plant likes moderate watering - for this it is necessary to warm the water to room temperature. The need for it is determined by the dried up top layer of the earth.
The frequency of the procedure increases up to 2-3 times a week during the period of active growth in the spring - the beginning of autumn. During the rest period, watering is stopped.
Top dressing
During the period of active growth of garrisia, regular fertilizing with cacti fertilizers is necessary. Nutrients contribute every 9-14 days.
Did you know? Garrisia begins to bloom at the age of 3 years, and the diameter of flowers can reach 20 cm!
Breeding
In the spring, during a planned transplant, activities are carried out aimed at breeding the species, which is carried out in two ways.
Cuttings
The cuttings are carefully cut with a sharp, sterilized knife - their size is about 5 cm. The cut is treated with charcoal. 1-2 days need a cutting for drying, after which it can be planted in the soil. Watering is done regularly through pallets, so that the process is rooted faster. 
Seeds
The material should be soaked in a 1% solution of potassium permanganate, then removed and wrapped in a damp napkin and kept for a day in a warm place. Then you can start sowing. To do this, use light soil with the obligatory presence of drainage. After that, the pot is covered with a film before the first shoots, creating the conditions for rapid germination. Watering is done regularly using warm water. Grown up cacti swoop down and sit in separate containers. 
Possible difficulties in growing
When growing Garrisia, there may be some difficulties, consisting in the development of diseases and plant damage by pests.
The most common ailments include:
- Root decay - occurs due to an excess of moisture or the use of cold water for irrigation, as a result of which the plant turns yellow and shrinks, and its stem softens. In case of incomplete tissue damage, it can be saved - the damaged part is removed, sections are treated with coal and transplanted into a new soil.
- Fusarium - the flower stops growing, turns pale, the affected parts acquire a rusty color. In this case, it is also necessary to remove the damaged tissue and treat the cactus with a fungicide, and then transplant.
- Antokroz - white spots on the surface of the flower testify to it, which subsequently dry, harden and crust. Sore spots are removed, cuts are covered with coal.
As for pests, such species are common:
- Mealybug - white mealy plaque indicates the presence of this pest. To get rid of it, it is necessary to spray the plant with a 0.1% solution of Karbofos, Aktellika or Benlata.
- Spider mite - rusty spots are formed on the plant. Measures to combat it are the same as in the above case.
The secret of the unusual flowering of cacti is simple - creating favorable conditions for their growth. In today's article, everything that is needed to grow garrisia is described in detail: if you follow the above recommendations, you can regularly admire the flowering of this type of cacti.
