There are many varieties of cacti, and they bloom beautifully with a variety of colors. Repotting is essential when caring for a cactus, especially for newly purchased ones, which often come bare-rooted or in unattractive pots. It is necessary to change the pot to a more attractive and suitable one to ensure normal growth and blooming. So, how should we repot it?
Cactus repotting is very simple. Whether it's received bare-rooted or in its original pot, first remove all the soil to expose most of the root system. Cacti have thick main roots and thin capillary roots. What we need to do is cut off all the capillary roots, leaving none, and slightly trim the thicker main roots without leaving them too long. After this pruning, place the cactus in a well-ventilated area with diffused light for 5 to 7 days. During this period, the remaining capillary roots will completely dry out, and the pruned wounds will heal completely. It's even possible that new capillary roots may grow from the remaining main roots during this drying process. Once dried, we can proceed to plant it.
When keeping a cactus at home, remember to use well-draining soil. It is recommended that granules make up 5 to 7 parts of the mixture. These granules can be things like coal slag, volcanic rock, iris stone, or coarse river sand. The rest can be nutritious soil such as peat, leaf mold, or ready-made nutrient-rich soil. The pot should not be too large; if your cactus has a diameter of 10 centimeters, you should choose a pot that is 12 to 15 centimeters in diameter. Avoid using too large or tall pots, and try to use breathable clay or terracotta pots, or red pottery pots.
Plant the cactus directly in moist soil with a moisture content of 30% to 50%. Place it in an area with diffused light and ensure good ventilation. After two to three days, when the potting soil is completely dry, water thoroughly. Add a few drops of root stimulant to the water. This will help the cactus quickly fill the pot with roots. Once the ball starts to look plump and the top begins to grow and turn green, gradually move it to a place with ample sunlight and add some fertilizer.
This is the method for repotting a cactus. Remember, the temperature for repotting must be above 15 degrees, which is its growing season. If you want it to bloom, place it in the sunniest spot and choose a fertilizer high in phosphorus and with no lack of other elements, such as "Flower多多 2". Apply once or twice a month, and water according to the principle of watering when dry. This way, the cactus you care for will definitely bloom. If the ball is not too small, it can bloom continuously throughout the year. Although the blooming period is short, if your cactus grows large enough, it can produce dozens of flowers at a time, and the flowers will bloom continuously, looking very beautiful.
The above is a detailed introduction to how to repot a cactus and the timing and methods of doing so. Have you understood it?
