Everything it needs
9 essentials at a glance
Watering
Pachyphytum oviferum, commonly known as the Moonstone plant, prefers to be watered thoroughly but infrequently.
Water when the top 1-2 inches of soil are dry, typically every 2-3 weeks during the growing season (spring and summer) and less frequently in fall and winter. Signs of over-watering include yellowing leaves and mushy stems, while under-watering may cause leaves to shrivel and drop.
Light
This plant thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, it should receive around 6 hours of light daily, with some morning sun being beneficial. Too much direct sunlight can scorch the leaves, while too little light may hinder growth and cause leggy stems.
Soil
Pachyphytum oviferum prefers well-draining soil with a pH range of 6.0 to 7.0.
A cactus or succulent potting mix is recommended, or you can create your own by mixing regular potting soil with sand and perlite to enhance drainage.
Humidity
This succulent prefers low humidity levels, ideally around 30-50%.
To increase humidity, you can mist the plant lightly or place it on a pebble tray filled with water. Signs of low humidity stress include leaf shriveling and browning edges.
Temperature
The ideal temperature range for Pachyphytum oviferum is between 65-80°F (18-27°C).
It can tolerate temperatures as low as 50°F (10°C) but should be protected from frost. This plant is suitable for USDA hardiness zones 9-11.
Fertilizing
Use a balanced, diluted liquid fertilizer with an NPK ratio of 10-10-10 during the growing season, approximately once a month.
Fertilizing should be reduced or stopped in fall and winter. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Pruning is generally not necessary for Pachyphytum oviferum, but you can remove any dead or damaged leaves to maintain its appearance.
Use clean, sharp scissors or pruning shears for this task. Deadheading is not applicable as this plant does not produce flowers regularly.
Repotting
Repot every 2-3 years or when the plant outgrows its pot, typically in spring.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. To repot, gently remove the plant from its pot, shake off excess soil, and place it in fresh potting mix.
Propagation
Propagation can be done through leaf cuttings or offsets.
For leaf cuttings, take a healthy leaf, allow it to callous for a few days, then place it on well-draining soil. Water sparingly until roots develop. The best time for propagation is during the spring or early summer when the plant is actively growing.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or poor drainage.
How to fix it
Allow the soil to dry out completely before watering again, and ensure the pot has adequate drainage holes.
Shriveled leaves
Why it happens
Under-watering or low humidity.
How to fix it
Increase watering frequency and ensure the plant is in a suitable humidity range.
Leggy growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location with indirect sunlight to promote compact growth.
Root rot
Why it happens
Excess moisture in the soil.
How to fix it
Remove the plant from the pot, trim away affected roots, and repot in fresh, dry soil.
Leaf drop
Why it happens
Sudden temperature changes or stress.
How to fix it
Maintain consistent temperatures and avoid placing the plant in drafty areas.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize monthly with a balanced liquid fertilizer.
Summer
During summer, ensure the plant receives plenty of bright, indirect light and water every 2-3 weeks, allowing the soil to dry out between waterings.
Fall
In fall, gradually reduce watering as the plant's growth slows. Monitor for any signs of stress as temperatures begin to drop.
Winter
In winter, water sparingly, only when the soil is completely dry. Keep the plant in a warm location away from drafts and cold windows.
Toxicity & Safety
Pachyphytum oviferum is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset. Always monitor pets and children around plants.
