Should cacti be planted deeply or shallowly?
This article provides you with the knowledge of whether to plant cacti deeply or shallowly and the best time for repotting cacti, offering some excellent plant cultivation tips. It's worth collecting!
Hello everyone, I am Plant Bug, who loves greening and flower cultivation. Today, a netizen asked, what should I do if my cactus has rotten roots? Is there any way to save it? Can I put it in the yard to dry for a few days?
Key point: Cacti and other similar plants are typical succulents, which prefer high temperatures and dry environments and are afraid of waterlogging. Therefore, when cultivating cacti, be careful with watering, keep the potting soil fresh, and water after it is completely dry, which not only ensures good growth but also promotes flowering. Especially in enclosed balcony environments, you need to control your hands. For outdoor cultivation, it's almost unnecessary to manage, just add a little fertilizer to promote vigorous growth.
For the netizen's question, what should I do if my cactus has rotten roots? The most likely cause of cactus root rot is improper watering. The general solution is to remove the pot, prune, cut off all the rotten parts of the cactus, disinfect and dry the wound, and then use coarse sand to plant deeply to promote root growth. When planting with coarse sand, since there are no microorganisms in coarse sand, it will not cause wound infection. Keep the coarse sand slightly moist, and wait for the roots to grow before transplanting. This is the normal treatment method. However, many friends still can't handle it properly and continue to rot. Today, we are sharing a simpler method with you.
What should I do if my cactus has rotten roots? Just cut it and leave it in the corner of the wall to wait for root growth.
Cacti can store a large amount of water, so they are very drought-resistant. They won't die even in the driest environment. It can be said that cacti are undying, but they fear water. The roots are very fragile. If the potting soil is too moist and wet for a long time, the roots will turn yellow and eventually blacken and rot. Therefore, after the cactus rots, we can use its strong water storage characteristic to promote root growth.
1. Remove the pot and prune
Remove the cactus with rotten roots from the pot, then remove all the potting soil, and can directly wash the soil clean with water. After washing, prune directly. Be decisive and don't hesitate. The main purpose of pruning is to cut off the rotten parts until there is no more rot. This must be noted. If pruning is not thorough, it may continue to rot, and all previous efforts will be wasted.

2. Disinfect and dry the wound
After pruning, use fungicides such as carbendazim to dilute and soak the wound for disinfection. I suggest you do this step, but if you really don't have fungicides, you can skip it. You can also use wood ash to apply to the wound for disinfection. After disinfection, hang the plant upside down to dry the wound. Don't worry, even direct sunlight won't be a problem, until the pruned wound is slightly dehydrated, or even more drastic measures can be taken.
3. Leave it in a shaded corner to wait for root growth
The next step is crucial. As we mentioned earlier, cacti store a lot of water and are not afraid of drought, but they fear waterlogging. Therefore, for those who can't control their hands, I do not recommend potting or using coarse sand to promote root growth. Just leave the cactus in a shaded corner. Don't doubt it. It turns out that this way cacti grow roots well. Of course, in autumn, as the temperature gradually drops, the root growth rate slows down, but it's fine. They will grow roots before winter. Is a cactus with rotten roots annoying? If you cut it and leave it in the corner without paying attention to it, it will even burst roots.
4. Transplant into a pot after root growth
When the cactus left in the corner has grown roots, pay attention and wait until the roots turn from white to brown before transplanting into a pot. It is recommended to plant in moist soil and not to press too hard to break the roots. Just press slightly, then water after the soil is completely dry. In winter, pay attention to keeping the plant warm, as cacti are afraid of the cold. After the spring thaw, you can resume normal care and wait for flowering.
