About Curio repens / Mini Blue Chalk Sticks
Curio repens, commonly known as Mini Blue Chalk Sticks, exhibits a trailing growth habit with dense, powder-blue foliage, creating a visually appealing carpet. Typically ranging from 6 to 12 inches in height, this low-growing perennial is well-suited for arid and coastal environments, creating a cascading effect in containers or garden landscapes.
How to care for Curio repens / Mini Blue Chalk Sticks
Light: Curio repens need bright and direct sunlight for at least 6 hours a day. If grown indoors, place it near a south-facing window or under a grow light. If grown outdoors, protect it from intense afternoon sun in summer to prevent sunburn.
Soil: Curio repens prefers well-draining soil that is rich in organic matter. You can use a commercial succulent or cactus mix, or make your own by mixing equal parts of potting soil, coarse sand, and perlite or pumice. Avoid using soil that is too heavy or holds too much moisture, as this can cause root rot.
Water: Curio repens are drought-tolerant and does not need frequent watering. Water it only when the soil is completely dry, and then water thoroughly until the excess water drains out of the pot. Do not let the plant sit in water or soggy soil, as this can cause fungal diseases and rot. Reduce watering in winter, when the plant is dormant, and do not water at all if the plant is shedding its old leaves and growing new ones.
Fertilizer: Curio repens does not need much fertilizer, but you can apply a low-nitrogen plant food once a month during the growing season (spring and summer). You can also use a weak compost tea or a succulent plant food for container plants. Do not fertilize in winter, when the plant is resting.
Pruning: Curio repens does not need much pruning, but you can trim off any dead, damaged, or diseased leaves or stems. You can also cut back the plant in late summer, if it becomes too leggy or overgrown. Use clean and sharp scissors or pruning shears, and disinfect them before and after each use. You can use the cuttings to propagate new plants.
Propagation: Curio repens can be easily propagated by cuttings, leaves, offsets, or seeds. To propagate by cuttings, take a stem cutting of about 3 to 4 inches (7.5 to 10 cm) long, and let it dry for a few days until a callus forms on the cut end. Then, plant it in moist and well-draining soil, and water it lightly. It should root in a few weeks.
