Fairy Crassula, scientifically known as Crassula multicava, is a charming succulent. Also called Pitted Crassula or London Pride, this mat-forming evergreen offers glossy, rounded leaves and delicate starry white or pinkish flowers. Its attractive appearance and low-maintenance nature make it a popular choice for gardeners.
Caring for Your Fairy Crassula
Light Requirements
Fairy Crassula thrives in bright, indirect light or partial shade. While it can tolerate a few hours of direct morning sun, intense afternoon sun can scorch its leaves. Providing at least six hours of light daily promotes robust growth and abundant flowering.
Insufficient light causes the plant to become leggy, characterized by elongated stems and widely spaced, paler leaves as it stretches for illumination. This also results in reduced blooming. For indoor cultivation, placing the plant near a south-facing window or in a spot with bright, indirect light is suitable, and rotating the pot ensures even development.
Watering Practices
Fairy Crassula, like most succulents, thrives on a “soak and dry” watering method. Water deeply until liquid drains from the pot’s bottom, then allow the soil to dry out completely before the next watering. This approach prevents the roots from sitting in excessive moisture.
Overwatering often leads to issues such as root rot, yellowing foliage, or soft, mushy leaves. In contrast, insufficient watering can cause leaves to become wrinkled and shriveled. During the plant’s active growing seasons of spring and summer, watering may be more frequent. As temperatures cool and growth slows in fall and winter, reduce watering significantly. Always use pots with adequate drainage.
Soil Preferences
Fairy Crassula thrives in very porous and well-draining soil to prevent waterlogging and root rot. A specialized cactus or succulent potting mix is ideal, as these formulations are designed for rapid drainage. Such mixes often incorporate a high percentage of mineral grit, typically ranging from 50% to 70%.
To enhance aeration and drainage, these mixes commonly include components like coarse sand, perlite, pumice, or fine gravel. You can also create your own blend using equal parts succulent mix, coarse sand, and perlite. The plant prefers a neutral to slightly acidic soil pH, between 6.0 and 7.5, and heavy, moisture-retentive clay soils should be avoided.
Temperature and Humidity
Fairy Crassula thrives in moderate to warm temperatures, ideally between 60-75°F (15-24°C). While it can tolerate a broader range, prolonged exposure to temperatures below 30°F (-1.1°C) or above 109°F (43°C) can cause stress and leaf drop. Protecting the plant from frost is important, and bringing it indoors is advisable if temperatures are expected to fall below freezing.
It is beneficial to keep the plant away from sudden temperature fluctuations, such as those caused by drafts from windows or heating vents, which can lead to stunted growth. Fairy Crassula prefers drier air, and typical household humidity levels are generally sufficient. Ensuring good air circulation around the plant also helps deter fungal issues.
Fertilization Needs
Fairy Crassula does not require heavy fertilization; in many cases, it is not necessary for its health. However, a light feeding can promote more vigorous growth. If you choose to fertilize, apply it sparingly and exclusively during the plant’s active growing season in spring and summer.
Utilize a balanced, low-nitrogen fertilizer or one specifically formulated for cacti and succulents. It is advisable to dilute liquid fertilizers to half or even quarter strength to prevent root burn. Avoid fertilizing during the fall and winter months when the plant is dormant, as this can lead to fertilizer burn or harmful salt accumulation in the soil.
