A little knowledge to share with you the reasons for the rotting roots and stems of cacti and how to solve them in the aspect of green plants and flowers. Next, the editor will introduce to you.
Cacti, as drought-resistant plants, are loved by many people for their unique shapes and low maintenance requirements. However, it is common for cacti to have rotting roots and stems during cultivation. So, what are the reasons for the rotting roots and stems of cacti? And how to solve this problem?
Firstly, the main reasons for the rotting roots and stems of cacti are as follows:
1. Overwatering: Although cacti are drought-resistant, it does not mean they do not need water. If overwatered, it can lead to excessive moisture in the soil, causing the roots of the cacti to be unable to breathe normally, thus leading to rotting roots and stems. Therefore, when watering cacti, wait for the soil to be completely dry before watering thoroughly to avoid waterlogging.
2. Poor soil ventilation: If the soil used for cacti is not loose enough or the soil is not changed for a long time, it can lead to poor air circulation in the soil, causing the roots to be unable to breathe normally, and then causing rotting roots and stems. Therefore, choose loose and well-draining soil and change the soil regularly.
3. Pest and disease attacks: Cacti may also be invaded by pests and diseases, such as fungal infections and root-knot nematodes, which can cause the roots and stems of the cacti to rot. Therefore, it is necessary to observe whether there are pests and diseases attacking the cacti and deal with them in a timely manner if found.
4. Insufficient lighting: Cacti need plenty of sunlight for photosynthesis. If kept in a dark environment for a long time, it can lead to poor growth of the cacti, making the roots and stems fragile and prone to rotting. Therefore, place the cacti in a sunny location.
In response to the problem of rotting roots and stems in cacti, we can take the following measures:
1. Control watering: When watering cacti, control the amount of water, wait for the soil to be completely dry before watering thoroughly, and avoid waterlogging.
2. Improve soil: Choose loose and well-draining soil and change the soil regularly to ensure normal breathing of the roots.
3. Pest and disease control: Regularly check if cacti are attacked by pests and diseases, and take timely measures for prevention and control if found, such as using a moderate amount of —— or adopting biological control methods.
4. Increase lighting: Place cacti in a sunny location to promote healthy growth.
5. Prune the rotting roots and stems: If the cacti have already rotting roots and stems, immediately cut off the rotten parts to prevent the rot from spreading to the entire plant. At the same time, pay attention to applying some preservatives to the wounds after pruning to prevent bacterial infections.
In summary, the main reasons for the rotting roots and stems of cacti are overwatering, poor soil ventilation, pest and disease attacks, and insufficient lighting. To solve this problem, we need to control watering reasonably, improve the soil, strengthen pest and disease control, increase lighting, and prune the rotting roots and stems in a timely manner. Through these measures, the cacti can be revitalized.
