What are Blue Chalk Sticks?


Blue chalk sticks, scientifically known as Senecio serpens or Curio repens, is a striking succulent plant with fleshy, cylindrical, blue-grey leaves that resemble chalk sticks, hence the name. This unique plant is native to South Africa and is known for its drought-tolerant properties, making it a low-maintenance and beautiful addition to any garden or landscape.

How to Plant Blue Chalk Sticks


Planting blue chalk sticks is relatively simple if you follow these steps:

  1. Choose the right location: Blue chalk sticks thrive in bright sunlight, so choose a spot in your garden where the plant will get at least 6 hours of direct sun daily.

  2. Prepare the soil: Blue chalk sticks need well-draining soil to avoid root rot. Mix three parts potting mix with one part perlite or pumice to create an ideal soil blend for your new plant.

  3. Start with a healthy plant: Purchase a healthy blue chalk sticks plant from a trusted source or propagate one from cuttings.

  4. Planting: Dig a hole in the prepared soil that is slightly larger than the root ball of your plant. Gently place the plant in the hole and fill the hole with the potting mix, making sure not to cover the base of the stem.

  5. Watering: Water your newly planted blue chalk sticks thoroughly, allowing the moisture to seep in. After the initial watering, water the plant sparingly, only when the soil is completely dry.

How to Care for Blue Chalk Sticks


Following the proper care regimen will ensure that your blue chalk sticks plant stays healthy and attractive:


  • Frequency: Water your plant only when the soil is dry to avoid overwatering.
  • Seasonal changes: During winter, reduce the frequency of watering as the plant goes into dormancy and requires less water.


  • Frequency: Apply a balanced slow-release fertilizer once a year, preferably during spring or early summer.
  • Avoid over-fertilizing: Too much fertilizer can lead to leggy growth and poor coloring.


  • Timing: Prune your blue chalk sticks plant in the late winter or early spring when it starts to show new growth.
  • Technique: Pinch back or trim any overgrown or leggy stems to maintain a dense and compact growth habit.

Common Problems and Solutions


Although blue chalk sticks plants tend to be relatively problem-free, there are a few issues that may arise:

  1. Root rot: This is caused by overwatering or poorly drained soil. Ensure that your plant has well-draining soil, and only water when the soil is dry.
  2. Pests: Common pests that can attack blue chalk sticks include mealybugs, scale insects, and aphids. Treat these pests by applying rubbing alcohol, insecticidal soap, or neem oil.
  3. Frost damage: Blue chalk sticks plants are not frost-tolerant. If you live in an area that experiences frost, consider planting your blue chalk sticks in a pot that can be moved indoors during the colder months.

  • Rock gardens: A perfect addition to rock gardens, their vibrant blue color contrasts beautifully against the earthy tones of rocks and stones.
