Chalk Dudleya: Full Sun Plant
Dudleya pulverulenta
A dramatic, drought-tolerant succulent for hot sun and perfect drainage. It grows in the cool, wet season and rests in summer - keep it dry then. Never wet the powdery leaves from above; the farina coating is delicate and protects the plant. Plant on a slope or tilt the pot so water drains off the rosette.

What is Chalk Dudleya?
Chalk Dudleya (Dudleya pulverulenta) is a medium-care plant from the Crassulaceae family. Chalk Dudleya (Dudleya pulverulenta) is a striking rosette succulent native to Southern California and Baja California. Its broad silvery-white leaves are coated in a chalky wax (farina) that reflects intense sun, and in spring tall arching red stalks carry tubular red-to-yellow flowers loved by hum...
Chalk Dudleya grows up to 90cm, spread of 45cm, watering every 21 days, 2°C – 38°C, 20–50% humidity. It is suitable for indoor environments and safe for pets.
Unlike many popular species, Chalk Dudleya is safe to keep around pets. Without adequate drainage, root rot can develop within 42 days.
How to Care for Chalk Dudleya?
TLDR: Chalk Dudleya needs Direct sun, watering every 21 days, and temperatures between 2-38°C with 20-50% humidity.
How Often Should You Water Chalk Dudleya?
Water in the cool season when the soil dries, and withhold water almost entirely through summer dormancy. Always water at the base - overhead water marks the farina and invites rot in the crown.
How Much Light Does Chalk Dudleya Need?
Give full sun to bright light with a little afternoon shade in the hottest climates. Too little light makes leaves soft and stretched.
What Is the Best Soil for Chalk Dudleya?
Use very fast-draining, sandy or gritty mineral soil. A slightly acidic to neutral pH suits it; avoid rich, moisture-holding mixes.
What Pot Should You Use for Chalk Dudleya?
Use a shallow, well-drained pot and plant at an angle so water sheds off the rosette; unglazed terracotta is ideal. Avoid handling the leaves - fingerprints remove the protective wax.

What Diseases Commonly Affect Chalk Dudleya?
TLDR: Chalk Dudleya is susceptible to 5 known diseases. Monitor regularly for early detection.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Overwatering
Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Meaning & Symbolism
A symbol of endurance in harsh places - its chalky coat a living sunscreen for sun-baked cliffs.
