House growing conditions

Euphorbia trigon does not require a lot of attention from the grower, if you initially provide her with comfortable conditions.


Euphorbia loves bright light, is not afraid of direct sunlight. But you need to accustom yourself to the sun gradually, so as not to provoke burns. For uniform shoot growth, the pot is turned to the light source in different directions.


The plant loves fresh air, in the warm season it is carried out to the balcony or outdoor terrace. Stale air or close proximity to heating appliances will negatively affect the growth of succulents.

We recommend that you familiarize yourself with other succulents:

Temperature mode

The optimum temperature in the warm season is + 23 ... + 25 ° С; in winter, lower temperatures + 16 ... + 18 ° С are recommended.

Air humidity

The plant is drought tolerant, but responds well to a warm shower and spraying. When showering, you need to cover the soil lump, spray from a spray bottle with small holes. In winter, instead of water procedures, a soft-brushed brush is used to remove dust from foliage.

How to care at home

Euphorbia is not whimsical to care for, but for the normal development you need to know the subtleties of the procedures.


In spring and summer, the pot is watered once a week. In autumn, the interval is reduced to once every two weeks. In winter, moistening is only required so that the soil lump does not dry out, about once a month. When watering, it is desirable to defend the water from impurities, the temperature of the room water. The best method is irrigation of the soil.

Top dressing

Euphorbia should be fertilized during the spring-summer period with an interval between dressings of 3-4 weeks. Fertilizers are combined with irrigation using liquid complex formulations, such as Pokon and Bona forte. In winter, fertilizer is not carried out.

Important! It is not advisable to use organic fertilizers due to the large amount of nitrogen. For succulents, an excess of nitrogen is fraught with the formation of cracks in the skin.


Pruning stimulates the formation of side shoots, which gives the bush a more magnificent shape. It is desirable to carry out pruning in the spring, and the removed tops can be used for reproduction.

Consider how to trim the stem properly:

  1. Cut a section of the stem with a sharp knife.
  2. The slice should be wet from the oozing milky fluid, then sprinkled with powdered charcoal.
  3. Given the burning properties of the juice, you need to work in long gloves and glasses to protect the eyes.

Transplantation is carried out in the spring for young plants annually. An adult bush requires a capacity change every 2-3 years. For good plant growth, it is important in which soil and how to transplant.

Soil suitable for growing succulents and cacti can be purchased at a store for gardeners.

With self-preparation, the following mixture of equal parts is prepared:

  • soddy soil;
  • leaf soil;
  • peat;
  • coarse sand.
Such a composition has the necessary friability and passes air well to the root system. Before use, the soil is calcined or steamed over a water bath.

Succulents have a superficial root system, so you need a wide pot, not a deep one. At the bottom lay a layer of gravel or pebbles as drainage.

Transplantation scheme:

  1. In order not to damage the roots, the bush is thrown out of the pot with an earthen lump.
  2. The remains of the soil are removed carefully, inspect the roots, removing damaged or dry areas.
  3. A hill of earth is poured onto the drainage, from above, spreading the roots, a bush is placed.
  4. Soil is poured on the sides of the tank without deepening the growth point.
  5. For tall bushes lay a support.
For several days the plant rests from the procedure, adapts to new conditions.
