Succulents can be sown and planted by seeds. Before, they introduced succulent leaf cutting, branch cutting, and ramification propagation. In fact, succulents can also be reproduced by seed sowing
- Seed planting time
Succulent planting time is generally planted in autumn and spring. Heating can also be used for sowing in winter. Too high or low temperature will reduce the germination rate.
- Tool preparation
Water spraying and spray cans are required for leveling sowing. In addition, fungicides can prevent and control diseases caused by fungi (such as deuteromycetes and polyascos) in many crops.
It can be used for foliar spray, seed treatment and soil treatment.
Seedling boxes or yogurt boxes for seeding succulents, or Coke bottles are all acceptable, but seedling boxes are recommended for easy management.
- Preparation for sowing and mixing soil
The bottom layer: large particles of slag, ceramsite, etc., ventilation to prevent water accumulation.
Middle and upper layer: peat (providing nutrients), perlite (breathing, preventing soil compaction), vermiculite (moisturizing) 2:1:1, other small particles can also be mixed. Or matched seeding soil, nutrient soil.
Soil surface: vermiculite, moisturizing, no large particles, easy for seeds to take root.
- Soil disinfection
Disinfection method 1: According to the amount of soil, the microwave will be heated for 5-10 minutes. Spray the soil for sowing before the microwave, otherwise it will be easy to burn.
Disinfection method 2: Potassium permanganate disinfection. Pour potassium permanganate (available in pharmacies) into the water until it turns light purple. Soak the basin for 2 hours and then control the water.
It is recommended to use a microwave oven to sterilize the seeding soil, and heat it on high heat for more than five minutes to kill bacteria, insect eggs, grass seeds, etc. The disinfection ability of potassium permanganate and sun exposure is very limited, and the disinfection effect cannot be guaranteed.
- Start sowing and planting
The seeds of succulents are generally small, and it is almost difficult to achieve on-demand sowing, so it is usually carried out by sowing. Fold a piece of harder white paper in half to form a paper slot. Place the seeds carefully on the white paper, and then gently tap the back of the white paper so that the seeds can flow into the area you want to plant evenly and smoothly.
In addition, the variety label should be inserted in time after the seed is sowed to facilitate subsequent identification and management.
- Follow-up management
After the succulent seeds are sowed, they need to keep the soil moist. It is a very good method to cover and buckle the cover. Pay attention to regular replenishment of water. The larger the water is, the better. The amount of water supplemented by methods such as dip basin is often too large, so pay attention to the frequency and the degree of soaking. Generally, the first sloughing of Lithops is about 3 months after germination, and the first sloughing does not require water control.
Temperature is a very critical factor for seedling development. Temperature refers to the temperature at the location of the seed, not the temperature in the weather forecast, and not the temperature of the environment around the flowerpot. For example, when seeding with a film, the temperature outside the film and the temperature inside the film may be different, especially when there is sunlight. Therefore, in order to control the temperature more easily, during the sowing period, do not expose to the sun before removing the film or opening the buckle cover.
- Succulent seeds germinate
It takes several days or even dozens of days from sowing to emergence. Most varieties take more than 5 days, so please be patient and look forward to their germination. If the temperature and humidity are not appropriate, it may extend the time for seedlings to emerge. Some varieties are difficult to grow seedlings, and it may take longer.
Note that the emergence of seedlings has a peak period of 2-3 days, which means that most seedlings germinate in these few days. You can consider removing the film afterwards.
- Transplanting seedlings
The principle of succulent seeding, generally, seedlings can be transplanted at any period after germination. It is recommended to use toothpicks and tweezers to insert the seedlings under the roots of the seedlings so that the seedlings can be transplanted with soil.
