Cactus Care Guide: Easy Tips for Thriving Indoor Cacti

Cacti are popular for their low-maintenance needs and unique, striking appearance. These resilient plants come in many shapes and sizes and can thrive in various indoor environments, making them perfect for beginner plant lovers. Let's dive into everything you need to know about cactus care to keep your spiky friends happy and healthy.


1. Light

Cacti naturally thrive in sunny desert environments, so they need a lot of light. Place your cactus in a spot with plenty of direct sunlight, like a windowsill. Cacti love bright light for about 6-8 hours a day.


2. Watering

The key to watering cacti is less is more! Since cacti are designed to store water, they only need a deep watering once the soil has completely dried out. Overwatering is the number one cause of cactus problems, so be sure to let the soil dry thoroughly between watering sessions.


3. Soil & Potting

Cacti need well-draining soil to prevent root rot. Look for cactus-specific soil mixes, or make your own by combining regular potting soil with sand or perlite. Always use a pot with drainage holes to allow excess water to escape.


4. Temperature & Humidity

Cacti are well-suited to warmer climates and should be kept in temperatures between 18°c and 26°C. They can handle cooler temperatures during winter, but avoid exposing them to frost. Since they are desert plants, they prefer low-humidity environments.


5. Fertilizing

Though cacti don’t need much feeding, adding a balanced fertilizer diluted to half-strength during the growing season (spring and summer) can promote healthy growth. Only fertilize once every 2-3 months, and avoid fertilizing during winter dormancy.


6. Common Cactus Problems

  • Overwatering: This can cause root rot, which will make the cactus mushy or cause it to turn brown. Always check that the soil is dry before watering.
  • Sunburn: If your cactus is getting too much direct sunlight, you may notice white or pale spots. Move it to a slightly shadier location if this happens.
  • Pest Issues: Look out for pests like mealybugs and spider mites, which can damage your cactus. A mixture of water and neem oil is an effective natural remedy.
