CARE GUIDE

How to keep Aloinopsis Schooneesii.

Light

Living stone prospers with plentiful sunlight, and it will continue to grow in partially lit settings. Sunlight is vital for its health; too little light slows growth, while excessive exposure can cause sunburn. Native to areas with intense sun, it is adapted to those conditions.

Water

Living stones, well adapted to arid environments, showcase remarkable drought tolerance by storing water in their succulent leaves. These plants need watering only once every three weeks and thrive indoors, thanks to their low maintenance requirements and distinctive appearance, making them perfect for dry indoor climates.

Temperature

Living stone is native to regions where temperatures lie between 68 and 100°F (20 and 38°C). It prospers in these warm conditions but tolerates slight drops in temperature. For best growth, keep this temperature range throughout all seasons.

Fertilizer

For Living stone, light applications of fertilizer once or twice a year during the growing season are adequate. Do not fertilize in winter or summer while it is dormant. Cut back on fertilizer for plants that have been repotted and wait a couple of months after repotting before applying fertilizer. Fertilizing helps maintain healthy growth and encourages blooms.

Pruning

To maintain the shape of living stone, pruning is essential, particularly in the spring and autumn. This involves removing any redundant or dense branches. For propagation, cut healthy stems that have 5-6 leaves. Treat the cut ends with sulfur powder, and water the soil lightly to encourage successful rooting.

Pot & Repot

When repotting Living stone, pick a pot just a bit bigger than the current one that has good drainage. Use a gritty, well-draining cactus or succulent soil mix. Gently take the plant out of its old pot, brush away surplus soil, and set it in at the same depth. Hold off on watering for a few days so any root injuries can recover. Repot during spring or autumn and place the plant in a very well-lit spot.

FREQUENTLY ASKED

Reader questions.

What should I do if I give my Living stone plant too much or too little water?

Living stone and other succulents can survive without water for extended periods. However, if you neglect to water them for a month or more, your Living stone may appear thirsty and show signs of damage. An underwatered Living stone will look dull and wrinkled, with some plants even drying up completely or turning brown. The soil will be completely dried out. To remedy this, give your Living stone plenty of water by submerging the pot in water for 5-10 minutes. Once you feel moisture on the soil's surface, you can stop watering. Overwatering is harmful to Living stone plants and can cause root rot, which prevents the roots from obtaining nutrients and water. Root rot occurs when excess moisture leads to the growth of fungi and bacteria in the soil, damaging the roots. Symptoms of overwatering include yellow, swollen, and translucent organs, which may burst open. If left untreated, the plant may turn brown or black and the leaves may fall off easily. Check the soil to confirm if overwatering is the issue, as other problems can have similar symptoms. It is challenging but possible to save an overwatered plant if caught early. If you suspect overwatering, remove the plant from the pot and examine the roots and soil. Gently remove wet soil from around the roots and rinse them in room-temperature water to remove any lurking fungus. If the roots are dark brown or black, soft, mushy, or slimy, root rot has developed. If most of the roots are affected, it may be impossible to save the plant. However, if only a portion of the roots have rot, there is a chance to save it. To save the plant, use a sterilized cutting tool to remove unhealthy-looking roots. Dip the firm, pale roots in fungicide to eliminate any remaining spores. Repot the Living stone in fresh, well-draining soil. While this method does not always work, the plant usually makes a full recovery and produces new growth in the next growing season.

Why do I have to put fertilizer on my Living stone plant?

Applying plant food to Living stone during the growing season supports healthy growth and encourages mature specimens to produce blooms. Even though Living stone stores water and nutrients, fertilizing adds additional nutrients to the growing medium.

What are the sunlight requirements for living stones?

Living stones, or Aloinopsis schooneesii, thrive under abundant sunshine, requiring above 6 hours of sunlight for 'full sun' conditions and about 3-6 hours for 'partial sun' conditions. Sun exposure is crucial for their well-being, as insufficient sunlight retards their growth, while overexposure can lead to sunburn. It's important to monitor the movement of sunlight through your garden to find spots that offer the right balance of light and shade for these plants.

What temperatures are ideal for growing Living Stone plants?

Living stone plants thrive in areas with temperatures ranging from 68 to 100°F (20 to 38°C), loving the warmth. These plants are capable of handling slight drops in temperature, but for optimal growth, it's important to maintain this temperature range throughout the year. As heat-loving plants, they slow down their growth and enter a dormant state in winter. When temperatures dip below 0°C, it's crucial to move them indoors, preferably near a south-facing window for maximum sunlight exposure. Supplemental lighting may be necessary if natural light is insufficient. When the temperature falls below 20°C, it's advisable to reduce or stop watering to prevent root rot. Outdoor plants should not be watered at all in low temperatures, and if possible, use insulation methods like temporary greenhouses, plastic film, or fabric wraps to protect them during the cold.

How often do I need to water my Living stone?

Determining how often to water Living stone does not have a strict rule. The best approach is to check the soil's moisture level and only water when it is completely dry. You can assess the moisture level by either inserting your finger or a moisture meter into the soil. If you have planted it in a deep pot, you can use a stick or chopstick to do the same. If the soil feels slightly damp, it is advisable to wait a few days and check again. In general, most individuals will need to water their Living stone every two weeks during the summer and once a month during the winter. However, various factors can impact the watering frequency. The section below outlines some considerations that can assist you in determining how often to water.

When should I fertilize my Living stone?

Living stone plants require a light dose of fertilizer during the growing season, approximately 1-2 times a year. It is recommended to fertilize them in the spring and autumn, avoiding winter and summer when they are dormant. When repotting, be cautious and decrease the amount of fertilizer used. It's advisable to wait a few months after repotting before applying any fertilizer.

Can living stones grow with artificial lighting?

Yes, living stones can grow under artificial lighting, which is especially useful in winter or less sunny spaces. Indoor plants benefit from adequate lighting for optimal growth. LED lights are a popular choice because they can provide specific wavelengths needed by plants. Full sun plants require 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants require 10-20W/sq ft. The light source should be placed 12-36 inches above the plant, mimicking natural sunlight for 8-12 hours per day.

How should I care for my Living Stone if it's exposed to low temperatures?

Living stone plants favor high temperatures and struggle in cool climates, particularly thriving when the temperature stays above 20°C. In winter, ensure the temperature remains above 0°C to avoid frost damage. Exposure to temperatures below -5°C can weaken them, leading to wilting and root rot. If your plant suffers mild frost damage without immediate symptoms, observe it as it may begin to wither within a week. To manage frostbitten Living stones, trim the affected areas, checking for and removing any rotted roots. Propagation through cuttings might be necessary in this scenario. Promptly move the plant to a warm indoor setting beside a south-facing window for sufficient sunlight. Utilize supplemental lighting if natural light is not adequate.

What do I need to think about when watering my Living stone plant?

To properly water your Living stone, consider several environmental factors, such as container size, soil type, temperature, and humidity. The container you choose will determine how often and how much to water. Ensure the container has enough drainage holes for excess water to escape. In general, a small container holds less moisture and will need more frequent watering, while a larger pot retains more water and can be watered less often. Avoid using an oversized pot as this can lead to overwatering. When repotting, move to a container just one size larger than the current one. Opt for a shallow container, as Living stone has shallow roots. Watering frequency will differ between seasons. In winter, when growth slows down and the plant requires less water, water less often. The cooler air reduces water evaporation, causing the soil to stay wet for longer periods. Additionally, consider the overall climate in your area. If you live in a humid location with abundant rainfall, watering will be needed less frequently compared to dry and arid climates. Remember that conditions within the same geographic area can vary based on the season and indoor heating or air conditioning usage. For outdoor planting, a well-established Living stone plant in the ground usually doesn't require additional water beyond what it receives from precipitation and dew. However, during long dry periods, occasional watering may be necessary. In areas where Living stone can only be grown in containers, it can be moved outside during spring and summer when temperatures are suitable and brought back indoors as temperatures decrease. Potted Living stone plants kept outside generally require more water due to increased sun exposure, even if they are placed on a shaded porch.

When is it not a good idea to add fertilizer to my Living stone?

Living stone, like most plants, goes through a dormancy period where growth slows down. During the summer and winter, when the plant's growth stops, it's best to avoid using fertilizer. It's also recommended to refrain from fertilizing for the first couple of months after repotting in the spring.

What are the symptoms of inadequate light in living stones?

Living stones show several symptoms when exposed to inadequate light, including smaller new leaves, leggy or sparse growth, faster leaf drop, and slower or halted growth. Insufficient sunlight can also cause leaves to develop irregular color patterns, appear pale (indicating a lack of chlorophyll and essential nutrients), experience chlorosis, sunscald, leaf curling, wilting, or leaf scorching. These symptoms indicate the need for better light exposure to ensure the plant's health.

What should I do if my Living Stone suffers from high temperature exposure?

During the hotter months, Living stone plants should be kept below 38°C to avoid heat stress. Temperatures above 43°C halt their growth and cause water loss, wilting, and increased susceptibility to sunburn. To aid a sunburned plant, remove the damaged and decayed parts first. Protect the plant from direct afternoon sunlight until it shows signs of recovery and resumes growth. For instances of root rot resulting from overwatering during high temperatures, cease watering completely until new roots develop, indicating recovery.
