Cactus seeds germinate a few days after sowing
Let me tell you about how long it takes for cactus seeds to germinate and the steps for planting cacti, details are as follows:
Cactus flowers are very beautiful, and as long as the plant blooms, it can usually be pollinated to produce seeds, and cacti are no exception. However, for most cacti to successfully pollinate and produce seeds, cross-pollination is necessary, which means cacti of the same genus but different maternal plants must be杂交 to successfully pollinate. After successful pollination, it will form seed pods, which will mature and crack open in about a month. When the seeds turn black, we can harvest them directly, clean them, and then sow them.
Remember to clean the cactus seeds before sowing. All the fruit flesh must be washed off, or it can easily cause the seeds to rot. After the seeds are cleaned and dried, they can be sown. For the soil used to sow cactus seeds, it should be as breathable as possible. I usually use a mixture of perlite, vermiculite, and peat soil in a 1:1:1 ratio. This type of soil is breathable, water-permeable, and contains nutrients. Spread a layer of well-mixed soil at the bottom of the pot, and then cover the surface of the soil with a layer of fine vermiculite, about 2-3 mm thick.
The reason for doing this is that the roots of the cactus are very weak in the early stage after germination. If they come into direct contact with the soil, it's hard for them to take root. By covering a thin layer of vermiculite, which is soft and has large spaces, the roots can grow directly into the vermiculite. After the roots have penetrated 2-3 mm into the vermiculite, they will continue to grow longer, and more fine roots will develop. When they finally touch the nutrient-rich soil, they will root into the soil without any issues. This prevents the plant from drying out completely or rotting due to being unable to take root.
After the vermiculite is spread, remember to soak the potting soil thoroughly using the immersion method. Once soaked, sprinkle the seeds evenly on top, then find a spray bottle, add some carbendazim to it, and spray the seeds to moisten them. The surface of the soil should be 5-10 cm away from the top of the pot. Do not fill the soil directly to the rim of the pot. Then, cover the entire pot with plastic wrap and use toothpicks to make several holes in the wrap for ventilation, as otherwise, the seeds might rot. After planting, place the pot in a spot with diffused or bright light. Remember, it must be exposed to light; no light is not an option. Ensure the temperature is above 15 degrees Celsius. You will find that the seeds will start to germinate in about 7 days, and within a month, all the seedlings will have emerged. When the seedlings are relatively large, over 5 mm in height, gradually remove the plastic wrap to harden off the seedlings and let them grow. Then you can fertilize and care for them normally. Once they are large enough, you can transplant them into individual pots.
Sowing cactus seeds is very simple. Ensure the seeds are fresh, do not cover them with soil, expose them to light, and use plastic wrap to maintain humidity and raise the temperature. They will germinate quickly, it's as simple as that. Have you learned? Under the right temperature, cactus seeds can bloom in just over a year after sowing.
