Method of Sowing Cactus Seeds
Let's talk about the method of sowing cactus seeds and the introduction of green plants and flowers about the whole process of cactus seed germination. Please see the detailed introduction below.
The cactus, also known as the grass ball, is native to the desert regions of South America. It prefers a hot and dry environment, and different species produce flowers of different colors. Cactus propagation generally adopts the method of seed sowing. When sowing, it is best to choose sandy soil with certain permeability, and maintain the sowing temperature at about 25 degrees Celsius. After the seedlings emerge, place them in a well-ventilated environment. Next, let's get to know the sowing method of cacti in detail.
1. Potting Soil Selection and Treatment
It is best to choose loose and permeable sandy soil for sowing cactus seeds. A mixture of 50% coarse sand, 20% peat, 20% vermiculite, and 10% wood ash can be used as the growing medium. For cultivation, you can use ordinary black plastic flower pots. Before filling the pot with soil, disinfect the pot and the growing medium with a potassium permanganate solution. After disinfection, fill the pot with soil. Then, tap the bottom of the pot gently on the ground to make the soil settle about 1 centimeter, which is more suitable for future plant maintenance.
2. Seed Treatment
When you have cactus seeds, wash the fruit flesh off the surface with clean water. After washing, place them in a well-ventilated area to air-dry the surface moisture. When the moisture is dried, prepare a potassium permanganate solution diluted with a certain amount of cool water, making the potassium permanganate light pink. Then, place the seeds in it and soak for about 30 minutes. After taking them out, dry them before use.
3. Sowing
Cactus seeds are best sown between July and August. The temperature should be between 20 to 25 degrees Celsius during sowing. As the seeds are small, you can use a toothpick dipped in water to sow them. Plant the seeds on the surface of the soil without covering them with soil. Then, cover the top of the flower pot with a layer of plastic film to ensure seed growth humidity and prevent excessive evaporation of water. Make a few small ventilation holes in the plastic film with a toothpick to ensure seed ventilation. Finally, place the plant in a windless, diffused light environment. In about 7 days, the plant will grow into small balls.
4. Seedling Care After Germination
Three days after the cactus seedlings emerge, remove the plastic film covering the surface and move them to a semi-shaded, well-ventilated environment. After a month, move them to a bright, diffused light environment. As the cactus at this stage cannot withstand too strong light, if the light is too strong, you must shade it. Generally, young cacti prefer a relatively moist soil environment, so attention should be paid to the amount of watering. You can also use the immersion pot method to supplement plant moisture. Watering can be combined with fertilizing. Mainly apply a thin nitrogen fertilizer solution to promote plant root growth.
