Adeniums are perennial shrubs or small trees, native to tropical Africa, extremely popular and fashionable in indoor culture in our country for the last 10-15 years.

Why did flower growers fall in love with these plants and why, having once tried to grow Adenium, can they all no longer refuse it, but acquire new and new seeds and grow them in dozens of pieces? The answer to this question lies in the amazing exotic appearance of these Africans, each plant is unique in its own way with its stem shape. Immediately from the ground, many varieties give a thickening of the stem – a caudex, in which the plant stores nutrients and water before a dormant period. Leaves are fleshy, few. The plant forms a lot of stems and therefore the correct formation can achieve unique and bizarre forms of a mini-bush.

Adeniums

Adenium flowers are very beautiful, mostly rich scarlet five-petal, but other colors of flowers (yellow, white, black with red) are also possible. The pharynx of the flower, as a rule, is lighter in comparison with the main color of the petals. Adeniums can interbreed with each other and produce strong hybrids with valuable traits such as contrasting petal colors, variegated leaves and double flowers. Translated “Adenium” means “desert rose”.  The sap of the plant contains toxic substances, so do not forget about the precautions when caring for a flower: use gloves, wash your hands and tools thoroughly after work, do not place plants in children’s rooms.

How to choose Adenium seeds

Adenium seeds

The seeds of Adeniums are oblong, similar to rolled tubes. The seed coat is sandy to brown in color. To the touch, the seeds should be firm, made. You can check the germination of Adenium seeds by dipping them in water. Floating seeds are more puny and less likely to sprout than sunken seeds. In general, Adenium seeds on the market have a fairly high germination rate.   

Selection of soil for germination of Adenium seeds

Adeniums, like African plants, have special soil requirements .

They need:

  • soil with high moisture permeability;
  • fertile soil with a high content of nutrients;
  • warm soil.soil for adenium

Adeniums have the highest need for nutrients in the initial period of growth, so it is already necessary to sow in normal fertile soil. Another peak period for nutrient requirements is the flowering phase, when Adeniums will need top dressing.

Separate words deserve the high vulnerability of Adeniums to the appearance of rot, so the soil is selected so that water stagnation is not created.

The following substrates meet the above requirements:

  • Ready soil for succulents with a high content of perlite;
  • Perlite crumb in its purest form;
  • General purpose primer with perlite, zeolite, vermiculite, coarse river sand, coconut fiber or foam pieces.

The content of the above additives should be at least 30% of the total volume of the substrate. Not suitable for seed germination Adenium hydrogel, peat tablets and peat in its pure form.

Soil preparation for sowing Adeniums

It is very important that the soil is safe against pathogens of fungal plant diseases. To do this, the substrate is disinfected in one of the following ways:

  • A box with already poured soil is scalded with boiling water or warmed up in an oven;
  • If the volume of soil is small, it can be put in the microwave for several minutes (10 minutes at medium power is enough to kill pathogens);
  • Irrigate the substrate with a pink solution of potassium permanganate.

If pure perlite is taken for sowing Adeniums, then it is better to take a new, previously unused substrate.

Preparation of Adenium seeds for sowing

In general, Adenium seeds have a high degree of germination, and even without special treatment in a warm substrate with high humidity, they germinate well. However, in order to soften the outer shell of the seeds, they can be soaked directly in water and put in a warm place overnight. Another option is to soak in a soft cloth. This option is the most acceptable, since the seeds in a moist tissue immediately sprout, compared with complete immersion in water.

Before soaking, Adenium seeds can be disinfected and heated, and after soaking, they can be treated with root formation and growth stimulants.

  • Disinfection: dip Adenium seeds in a bag into a pink solution of potassium permanganate for 20 minutes, the temperature of the solution should be 38 ° C throughout the entire treatment period To get rid of microfungal spores, Fitosporin M solution is suitable;
  • Warming up: dry seeds of Adeniums in a dry bag are placed on a warm battery or heating pad – 2-3 days at a temperature of 37-40 ° C;
  • Processing in stimulants : Epin, Zircon, Radifarm, Ruter – according to the instructions – from several minutes to several hours.

How to sow Adenium

The best time for sowing is the end of winter – the beginning of spring. During this period, the length of the day gradually increases and you can not use the backlight for growing seedlings. In addition, for the summer it is better to take young Adeniums to the balcony – there will be more light and warmth for them, and they will get stronger by the dormant period next winter.

Sowing Adeniums can be done in two ways:

  1. In the finished substrate, it does not matter in a large container, sowing is done or in individual pots, indentations are made by 0.5-0.7 mm. Then the seeds are literally placed in the recesses horizontally and covered with a substrate from above.
  2. The seeds are also laid horizontally on the prepared substrate, and then the seeds are sprinkled on top with the same substrate with a layer of 0.5-0.7 mm.

If a common container is used for sowing, then the seed sowing pattern is at least 3 x 3 cm. After sowing, the soil is moistened with a spray bottle, then the container or each individual pot is covered with a film or plastic lid to create an internal microclimate and prevent moisture evaporation.

Germination temperature

Adenium seeds will not germinate at air and substrate temperatures below 26 ° C. The optimum temperature for seed germination is + 30-35 ° C , air humidity should be 95-100%, and substrate 90-95%. The film on the container or pot can be removed twice a day for 30-40 minutes for ventilation.

The soil in the container should not be waterlogged. Usually in such conditions shoots appear already on the 4th day. It happens that seedlings appear very quickly, but the outer skin of the seeds sits tightly on the cotyledon leaves. In this case, you need to try to soak it with warm water and carefully remove it, freeing the young leaves. Otherwise, the plant will stop its further development.

Experts recommend placing a container with crops on top of heating appliances or heating pads, dryers so that the air temperature at the bottom of the container is 35-37 ° C. Lighting is not needed during this period.

Adenium seedling care

When at least one sprout appears, the film is removed from the container and moved to the brightest place on the window, preferably from the south side. It must be remembered that the room must be warm. Watering should be carried out as the substrate dries slightly.

2-3 months after germination, Adeniums are planted in individual pots, but not too deep to prevent root rotting. The diameter of the pot should be approximately equal to the diameter of the crown of the shrub. Plants can be transplanted as many times as necessary to form the required plant size.

How to achieve flowering Adeniums

Experienced flower growers claim that Adeniums can bloom as early as the second year after sowing, but on average, with proper care, the desert rose blooms for 3-4 years. In order for shrubs to bloom, you need to provide them with a period of rest and a period of development with sufficient lighting. It is better that the dormant period of Adeniums coincides with the calendar winter, and development takes place in spring and summer.

During the dormant period, it is necessary to maintain the air temperature in the room at a level of + 12-15 ° C, watering should be very moderate. The plant may even drop leaves, this is quite normal. In spring and summer, the daylight hours are adjusted to 16 hours a day, and the air temperature is maintained at least 28-30 ° C , watering is sufficient, frequent, but after the soil has dried.

You can form a flower with a tree, if there is enough free space, or with a shrub. The operation of shaping and pruning is started in the third year after sowing. The tree is cut longer, no more than a third of the branch, and the shrub is shorter – up to half or more of the length of the branch. 

From about one and a half to two years of age, Adeniums are fertilized with complete organo-mineral  . At this time, the supply of nutrients after transplants ends. Do not fertilize plants too often, once or twice a month is enough, excluding the dormant period. Spring-summer top dressing should contain nitrogen and trace elements, and top dressing at the end of summer – only phosphorus and potassium.

Be sure to try sowing Adeniums and you will find your life’s work!
