How to Care for Blue Smoke Cactus?

The blue smoke cactus is a beautiful cactus plant that does not require much attention from the owner. The cactus comes in various varieties and to help them bloom, you need to provide the optimum conditions. Planting it indoors or outdoors depends on the climate, size, season, and age of your plant. Here’s how you can help your plant mature with the minimum care and proper conditions.

  • Soil: The blue smoke cactus likes well-drained and sandy soil. You can make a perfect soil mix for your cactus by mixing cactus and succulent soil mix and by adding some gravel. Add some pebbles at the bottom to ensure good drainage and an adequate amount of airflow. You can provide its native rocky surroundings to your cactus by adding gravel around the plant.
  • Water: These plants are drought tolerant and you need to water them only when the soil feels dry to the touch. While watering, give the plant a good soaking so that the water reaches till roots. Before any other watering session, you must check that the soil is completely dry. You need good drainage at the bottom to avoid water sitting at the roots for a long time. This can be done by adding gravel at the bottom and soaking the dirt and making the soil dry before watering. Follow the same technique to water your cactus. 
  • Light: The blue smoke cactus appreciates full sun and it can thrive well in partial shade as well. When the plant is in its young period, keep it under partial shade or light shade and once it is matured, you can move the plant outside to full sun shade. If you are keeping it inside your room, pick a south window spot where sunlight comes straight to your plant. 
  • Temperature: If you are living in hot climate conditions, put a partial shade on your plant during the afternoon. If you are living in cold conditions, keep your plant indoors as it cannot tolerate cold temperature that goes beyond -4 degrees Celsius. Warm temperatures are fine for these species but you have to care a little more if you belong to colder regions. 
  • Fertilizer: For steady growth of your blue smoke cactus plant, fertilize it once a month during the growing period. However, if you want to encourage the blooms, you can fertilize the cactus twice a month with a high-phosphorous cactus fertilizer. It is recommended to fertilize the plant during the blooming period which is spring and summer. The plant does not rely fully on fertilizers so never over-fertilize your cactus for healthy growth.
