A rotten cactus is the dread of many home and garden owners. You can tell the rot inside when the succulents suddenly become mushy. Various causes are possible. In addition, first aid can save the plant if necessary.
Before treatment, the owners should ask themselves, why did the cactus become soft? Various causes are conceivable:
- wrong watering
- too little light
- wrong substrate
Improper watering is a common cause of rot development. If you water the exotic plant too generously, water will collect in the substrate. The plants are very sensitive and react quickly to waterlogging. After all, the plants are used to dry locations. The moisture in the soil causes the roots to rot. Bacteria and fungi can penetrate faster and destroy the entire cactus.
Too little light
Lack of light favors the development of rot. In many plants, the base remains comparatively thin while the cactus grows rapidly. Such forms are common when the plant gets too little light. Consequently, you should make sure that the Cactaceae are in a sufficiently sunny location.
With the wrong substrate, you won’t make the plants happy. If you fill the pot with the wrong material, you will soon have a rotten succulent in your garden. Preferably, the Cactaceae should have a substrate with little humus and lots of minerals. The plants thrive best with this combination.
If the cactus gets yellow spots, the sunlight can be the cause. Direct exposure to the sun’s rays is not suitable for all types of succulents. Sunburn damages the plant and promotes the development of rot.
Soft, injured cacti allow bacteria and fungi to enter the plants. Such openings are conceivable by animals, insects or weather influences. The bacteria and fungal spores now have an easy time penetrating the succulents. Subsequently, the plants become rotten from the inside. The growth of fungal spores is favored in warm and humid site conditions.
Save soft cactus
If the cactus is already completely soft and mushy, help may come too late. However, if rotting is not very advanced, you can save your cactus. First check if the upper part is healthy. Then, with the right materials and a few tips, you can take care of your plants.
If you want to save your muddy plants, you need different materials. The rescue is not possible without the following items:
After the preparations, it is necessary to separate the healthy part of the plant from the rotten pieces. Take a sanitized knife and cut out the rotten spots. The wounds of the plant can be treated with charcoal. Otherwise, bacteria and fungi could get into the cactaceae and promote rot again.
Before you replant the cacti, the wounds must dry. With wet wounds there is always a risk that the succulents will rot again. Consequently, a waiting time of 1-2 days is recommended before the cactus comes into the substrate.
A special and high-quality substrate is required for planting. Products containing minerals are recommended for the plants to thrive. In addition, drainage is useful in order to be able to quickly drain moisture from the substrate.
