Cacti are fascinating plants that have adapted remarkably well to their harsh environments. When caring for cacti as ornamental plants, it’s essential to provide them with well-draining soil, ample sunlight, and moderate watering, as they are susceptible to rot in overly moist conditions.

Why is my indoor cactus dying?

There are several reasons why an indoor cactus might be dying. Diagnosing the exact cause can be a bit tricky without more information, but here are some common factors that could contribute to the decline of your indoor cactus:

  1. Overwatering: Cacti are adapted to survive in arid conditions and can be sensitive to overwatering. When the soil stays consistently wet, the cactus roots can rot, leading to poor health and eventual death. Make sure you allow the soil to dry out between waterings and avoid leaving the plant in standing water.
  2. Poor Drainage: Inadequate drainage can exacerbate overwatering issues. Cacti require well-draining soil to prevent water from accumulating around the roots. Ensure your pot has drainage holes, and consider using a cactus-specific potting mix or adding sand or perlite to improve drainage.
  3. Lack of Sunlight: Cacti need plenty of sunlight to thrive. If your indoor cactus isn’t getting enough light, it may become weak and leggy, with pale green color. Make sure to place your cactus in a location that receives bright, indirect sunlight for most of the day.
  4. Pests and Diseases: Cacti can be susceptible to pests like mealybugs, spider mites, and scale insects. These pests can weaken the plant and make it more vulnerable to diseases. Inspect your cactus regularly for signs of pests or diseases, such as wilting, discoloration, or sticky residue.
  5. Temperature and Humidity: Some cacti are sensitive to extreme temperatures or humidity levels. If the environment is too cold or too humid, it can stress the plant and lead to health issues. Keep your indoor cactus in a room with temperatures between 60-80°F (15-27°C) and avoid placing it near heating or cooling vents.
  6. Nutrient Imbalance: Cacti generally don’t require frequent fertilization, but they still need some essential nutrients to grow and thrive. If you’re using fertilizer, make sure it is formulated for cacti, and follow the recommended dosage. Too much fertilizer can harm the plant.
  7. Root Bound: Over time, cacti can outgrow their pots, and their roots become root bound, meaning they have little room to grow. This can lead to decreased nutrient uptake and water retention. If your cactus has been in the same pot for a long time, consider repotting it into a slightly larger container.
Why is my indoor cactus dying?

To determine the specific cause of your indoor cactus’s decline, carefully assess its growing conditions and look for any signs of stress or damage. Adjust the care accordingly based on the potential issues mentioned above. In some cases, it may be possible to save a struggling cactus if the problems are identified and addressed early enough.

Do you water cactus from the top or bottom?

When watering a cactus, it’s generally best to water from the top rather than from the bottom. Here’s why:

Watering from the top:

  1. Even Distribution: Watering from the top allows you to evenly distribute water across the soil surface, ensuring that all parts of the root system receive moisture.
  2. Checking Soil Moisture: By watering from the top, you can observe how the water is absorbed by the soil and monitor its moisture level. This helps prevent overwatering, as you can stop once you see water starting to drain out of the bottom of the pot.
  3. Cleaning Dust and Debris: Watering from the top helps wash away any accumulated dust or debris on the cactus and the surface of the soil.
  4. Mimicking Rainfall: In their natural habitat, cacti often experience rain from above, so watering from the top replicates this natural watering method.

When watering your cactus from the top, it’s essential to use a watering can or a container with a narrow spout to avoid drenching the cactus unnecessarily. Additionally, always water the soil directly and avoid wetting the cactus itself to prevent potential rot or fungal issues.

Watering from the bottom:

Do you water cactus from the top or bottom?

While watering from the bottom is not the preferred method for cacti, it can be useful in certain situations, such as when you have a cactus planted in a large pot that is too heavy to lift easily or if you want to encourage the roots to grow deeper. The process involves placing the pot in a shallow container filled with water and allowing the soil to absorb water through the drainage holes. However, this method requires close monitoring to ensure that the soil is sufficiently moistened without becoming waterlogged.

Overall, for most cacti, watering from the top is the safer and more effective approach. Remember that cacti prefer infrequent but deep watering, allowing the soil to dry out between waterings to prevent root rot and other water-related issues. The specific watering frequency will depend on the cactus species, the size of the pot, and the environmental conditions, so it’s essential to observe your cactus and adjust your watering routine accordingly.

Are cactus hard to keep alive?
