Everything it needs
9 essentials at a glance
Watering
Claytonia perfoliata prefers consistently moist soil, requiring watering every 2-3 days during dry spells.
In cooler months, reduce frequency to once a week. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in partial shade to full sun, ideally receiving 4-6 hours of direct sunlight daily.
It can tolerate some shade, especially in hotter climates, but too much shade may result in leggy growth.
Soil
Claytonia perfoliata prefers well-draining, loamy soil with a pH range of 6.0 to 7.0.
A mix of potting soil, compost, and sand is recommended to ensure proper drainage.
Humidity
The plant enjoys moderate humidity levels around 40-60%.
To increase humidity, mist the leaves or place a humidifier nearby. Signs of low humidity include browning leaf tips and stunted growth.
Temperature
Ideal temperatures range from 50-75°F (10-24°C).
It is hardy in zones 3-9, tolerating light frost but may bolt in extreme heat. Protect from temperatures above 85°F (29°C) to prevent stress.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune in early spring to remove any dead or damaged leaves.
Use clean, sharp scissors for a clean cut. Deadheading is not necessary, but removing spent flowers can promote a tidier appearance.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Choose a pot 1-2 inches larger in diameter. Signs include roots growing out of the drainage holes. Carefully remove the plant, refresh the soil, and place it in the new pot.
Propagation
Claytonia perfoliata can be propagated through seeds or division.
For seeds, sow directly in the garden in early spring or late summer. For division, carefully separate clumps in spring and replant immediately.
