Regarding care, Stonecrop is drought tolerant but requires more water in the growing season. Watering should be greatly reduced or stopped entirely during the dormant period. Stonecrop is suitable for growers with some experience, though it can be difficult to maintain, particularly during dormancy. It is especially appropriate for people who can devote time to its care over the winter months.
How to keep Crassula Orbicularis.
Light
Stonecrop comes from a habitat with abundant sunshine, which thoroughly supports its healthy growth and development. It can also thrive under comparatively lower light levels. Both excessive and insufficient light can hinder the plant's health and potentially cause harm.
Water
Stonecrop thrives in dry conditions, needing water only once every three weeks. This drought-tolerant plant prefers well-draining soil and is low-maintenance, especially indoors. Just ensure the soil dries completely between waterings to prevent waterlogging and keep your stonecrop healthy.
Humidity
This plant will thrive in moderate humidity, which is probably the level in your home. However, misting it a few times a week can be very beneficial. Make sure the room has good ventilation.
Temperature
Although Stonecrop can tolerate some heat, it mainly does best and grows during the cooler seasons and becomes dormant in summer. In hot summer conditions, providing shade is important to avoid scorching from intense sunlight. Watering should be reduced or stopped during the hottest part of the year to prevent root rot. Stonecrop grows vigorously in winter and spring. If temperatures do not fall too low, it will continue to grow steadily.
Fertilizer
Stonecrop only needs light fertilizer once or twice a year during the growing season. Do not fertilize in winter or in summer when it is dormant. Cut back on fertilizer for plants that have been repotted, and wait a couple of months after repotting before you fertilize. Fertilizing helps maintain healthy growth and encourages flowering.
Pruning
To keep stonecrop plants in good shape, you may need to prune them, especially during the spring and autumn. Use tools like knives or scissors to trim away any excess or overly dense branches. If you're looking to propagate the plant, choose strong stems with 5 to 6 leaves. Before planting, treat the cut ends with sulfur powder and gently moisten the soil.
Pot & Repot
Repot stonecrop every two years in the spring. Use a slightly larger pot with excellent drainage. Make sure to provide well-draining soil, minimal water, and bright, indirect sunlight. Handle the stonecrop gently after repotting to avoid damage and be careful not to overwater it to ensure optimal growth.

Reader questions.
What should I do if I give my Stonecrop plant too much or too little water?
Stonecrop and other succulents are typically able to withstand long periods without water, but if you forget to water your Stonecrop for a month or more, it will likely show signs of thirst and damage. An underwatered Stonecrop will look lacklustre, wrinkled, and some leaves may have dried up completely. The soil will also be completely dried out. To remedy this, thoroughly water the plant by submerging the pot in water for 5-10 minutes until you feel moisture on the soil's surface. On the other hand, overwatering can be detrimental to Stonecrop as it can lead to root rot. Root rot occurs when fungi and bacteria thrive in overly moist soil, preventing the roots from absorbing nutrients and water. Signs of overwatering include yellow, swollen, and translucent leaves, which may burst from being over-full with water. If untreated, the plant may eventually turn brown or black and leaves may fall off easily. To address overwatering, improve air ventilation, adjust watering frequency, and check the soil for excess moisture. Saving an overwatered plant can be difficult, but it's crucial to act early. Start by removing the plant from its pot and examining the roots and soil. Rinse the roots with room-temperature water to remove any fungus and assess their health. If the roots are dark brown or black, soft, mushy, or slimy, they have likely succumbed to root rot and saving the plant may not be possible. In this case, salvage any healthy stems for propagation. If some roots remain unaffected, use a sterilized tool to remove the unhealthy ones and dip the remaining roots in a fungicide. Repot the plant in fresh, well-draining soil. Although not always successful, this process can often lead to a full recovery and new growth in the next growing season.
Why should I put food on my Stonecrop plant?
When you add fertilizer to Stonecrop, it provides important nutrients for the growing medium. While Stonecrop does store water and nutrients, applying plant food during the growing season is beneficial for promoting healthy growth. Additionally, fertilizing can stimulate mature Stonecrop plants to produce blooms during the growing season.
What kind of sunlight requirements does Stonecrop have?
Stonecrop requires full sun exposure of above 6 hours of sunlight daily but can also thrive in partial sun, receiving about 3-6 hours of sunlight. It's essential to observe how sunlight moves through your garden to find the ideal spots that offer the perfect balance of light and shade. This careful placement ensures the plants' growth and happiness by meeting their sunlight needs effectively.
What are the essential growing conditions for Stonecrop?
Stonecrop thrives in warm environments, needing higher temperatures during its growing season to enhance growth and metabolism. It loves being in ample sunlight and requires proper moisture levels coupled with good air circulation. The plant, however, is vulnerable to damage from extremely low temperatures and excessive watering. It's crucial to maintain a balance, avoiding too much heat and overly arid conditions as well. Stonecrop prefers heat and goes dormant in winter. As temperatures drop below 5°C, it's advisable to move it indoors, placing it near a south-facing window to ensure it gets enough sunlight. If natural light lacks, additional lighting might be needed. When temperatures fall below 20°C, the plant's growth decelerates, prompting a reduction or complete halt in watering to prevent root rot. For outdoor Stonecrops, stop watering altogether in cold temperatures. If possible, insulate them using a temporary greenhouse or wrapping materials like plastic film or fabric.
How frequently should I water my Stonecrop plant?
Determining how often to water Stonecrop isn't a strict rule. Instead, you can check the soil and water only when it is completely dry. To check the soil moisture, you can either use your finger or a moisture meter. In a deep pot, you can use a stick or chopstick to do this. If the soil feels slightly moist, it's best to wait a few days and check again. Generally, most people will need to water Stonecrop approximately every two weeks during summer and once a month in winter. However, there are various factors that can influence the watering frequency, which are listed in the section below for your consideration.
When should I fertilize my Stonecrop plant?
Stonecrop, unlike other plants, only requires a small amount of fertilizer during the growing season. It is recommended to fertilize it once or twice a year, specifically in the spring and autumn, while avoiding winter and summer when it is dormant. When repotting Stonecrop, be cautious with the amount of fertilizer used, reducing it if necessary. It is also advisable to wait a couple of months after repotting before applying any fertilizer.
What are the essentials for Stonecrop's healthy growth and development?
Stonecrop originates from environments with ample sunlight, which is critical for its robust growth and development. While it can grow under lesser light conditions, the right amount of light is crucial; too little or too much can harm the plant. When natural sunlight is not enough, especially in winter or less sunny spaces, artificial lighting can be a great alternative. Indoor plants may require 8-12 hours of artificial light per day, using LED lights or other suitable sources, placed 12-36 inches from the plant to mimic natural sunlight conditions.
How should Stonecrop be cared for in low temperatures?
Stonecrop prefers warm temperatures and struggles with cold, flourishing best when the temperature is above 20°C and needing to be kept above 5°C during winter. Exposure to temperatures below 1°C makes the plant vulnerable to weakening, wilting, and root rot. If frost damage occurs, there might not be immediate symptoms, but the plant could gradually wither after a week. To assist a frost-damaged Stonecrop, trim off frostbitten areas and check for root rot – if found, remove the rotted roots, then propagate the plant using cuttings. It's important to move the plant indoors to a warmer spot, ideally near a south-facing window to maximize sunlight exposure. If sunlight is inadequate, supplement it with artificial lighting.
What do I need to think about when I water my Stonecrop?
Stonecrop's watering needs are influenced by various environmental factors such as container size, soil type, temperature, and humidity. The container and soil you choose will determine the frequency and amount of water needed. Make sure to use a container with good drainage to prevent water from pooling. Smaller containers hold less moisture, so they need to be watered more often compared to larger pots. It's important to avoid using excessively large pots as this can result in overwatering. When repotting, go up only one size larger than the current container, and opt for a shallow container since Stonecrop has shallow roots. During winter, Stonecrop requires less frequent watering due to slower growth and reduced water usage. The cooler winter air also reduces evaporation, causing the soil to stay wet for a longer duration. The climate of your location also affects the watering schedule. In a humid region with ample rainfall, you will need to water less frequently compared to a dry, arid climate. Keep in mind that even within the same geographic area, conditions can vary based on the season and indoor heating or air conditioning usage. If Stonecrop is planted in the ground, it usually won't require additional watering beyond natural precipitation and dew. However, during prolonged dry periods, occasional watering may be necessary. In areas where Stonecrop can only be grown in a container, it can be moved outdoors during suitable spring and summer temperatures and brought back indoors as temperatures begin to drop. When kept outside, potted Stonecrop generally needs more water due to increased sun exposure, even if it's placed on a shaded porch.
When is not a good time to fertilize my Stonecrop?
Stonecrop, like other plants, has a dormancy period when it stops growing. During the summer and winter, it's best to avoid applying fertilizer. It's also advisable to refrain from fertilizing for the first few months after repotting in the spring.
What symptoms indicate that a Stonecrop is experiencing light deficiency?
Symptoms of light deficiency in Stonecrop include smaller new leaves, leggy or sparse growth, faster leaf drop, delayed or halted growth, and lighter-colored or irregularly patterned new leaves. Conditions such as chlorosis, sunscald, leaf curling, wilting, and leaf scorching can also indicate that the plant is suffering from inappropriate light conditions, whether it be too much or too little light. These symptoms demonstrate the plant's struggle to adapt to its lighting environment, affecting its health and appearance.
How does high temperature affect Stonecrop?
During the hotter months, it's critical to ensure that Stonecrop's temperature does not exceed 41°C. If the temperature rises above 45°C, the plant will stop growing, suffer from water loss, wilting, and is at a higher risk of getting sunburned. To recover a plant affected by high temperatures and sunburn, remove the damaged sections and protect the plant from direct afternoon sunlight until it shows signs of recovery and resumes growth. In instances where root rot has set in due to overwatering, cease watering until new root growth is evident.
