How To Care For Cactus

Cactus

☀️- Prefers bright, direct sunlight. Most cacti thrive in full sun for several hours a day, but some species tolerate bright, indirect light.

💧- Water thoroughly in spring and summer, allowing the soil to dry out completely between waterings. From autumn to spring, reduce watering significantly and stop altogether during the coldest months to prevent root rot.

🌡️- Thrives in temperatures between 18°C to 30°C. Protect from frost and avoid temperatures below 5°C.

🪴- Repot every 2-3 years in spring using a well-draining cactus mix. Ensure the pot has drainage holes to prevent water retention.

🐾- Mostly non-toxic, but some species have spines that can be harmful to pets.

Cacti belong to a vast and diverse group of succulents, primarily native to the Americas, thriving in arid environments where they have adapted to store water in their thick, fleshy stems. With their striking architectural shapes and low-maintenance nature, they make excellent houseplants for those who prefer minimal care. Despite their resilience, cacti still require the right balance of light, water, and temperature to thrive indoors.

Care

Cacti need bright, direct sunlight for at least 4-6 hours daily. A south or west-facing window is ideal. They prefer warm temperatures between 18-30ºC and should be kept away from cold draughts. Water sparingly, allowing the soil to dry out completely between waterings—typically every 2-4 weeks in summer and even less in winter. Overwatering is the most common cause of failure. Use a well-draining cactus mix and a pot with drainage holes.

During the growing season (spring and summer), feed monthly with a diluted cactus fertilizer. Repot every few years to refresh the soil and accommodate growth.

Problems

  • Wrinkled or shrivelled stems – Underwatering; increase watering slightly.
  • Soft, discoloured, or mushy spots – Overwatering or rot; reduce watering and remove affected areas.
  • Stretching or elongated growth – Insufficient light; move to a brighter spot.
  • Lack of flowering – Not enough light or improper dormancy period.
