Common Names:
The Lithops fulleri N.E.Br. var. rouxii goes by several common names, apart from the Fuller's living stone. It is also known as the Rough living stone, the Grofleipoldt, the Fatma's living stone, and the Wijersberg living stone.
Uses:
The Lithops fulleri N.E.Br. var. rouxii is mainly grown as an ornamental plant due to its unique appearance. They make great additions to rock gardens, windowsills, and indoor succulent collections. Additionally, this plant species serves as an excellent indicator plant, helping to indicate changes in the environment such as water availability and temperature changes.
General Appearance:
The Lithops fulleri N.E.Br. var. rouxii is a small, low-growing plant, with a mature height of 2.5 cm and a diameter of up to 10 cm. It forms clumps of individual leaf pairs reminiscent of a "living stone." These grow underground for most of the year, leaving only the top of the leaves exposed for photosynthesis. The leaves are fused at the base, usually with a cleft between them, and are thick, nearly flat, and usually beak-shaped, giving the "living stone" look. The color of the leaves is usually a dull greyish-green, but older leaves may turn brownish-grey. It produces small daisy-like white or yellow flowers that bloom in the fall.
Light Requirements
Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole prefers bright, indirect light. Direct sunlight can scorch the leaves of the plant. The plant should be placed in an east or west-facing window where it can receive morning or evening sun. Artificial grow lights can also be used to provide the ideal lighting conditions for the plant.
Temperature Requirements
The plant thrives in warm temperatures ranging from 60-80°F (15-27°C). The plant is native to the hot and arid regions of South Africa and can tolerate high temperatures. However, abrupt fluctuations in temperature can cause damage to the plant. It is essential to avoid exposing the plant to temperatures below 50°F (10°C).
Soil Requirements
Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole prefers well-draining soil with good aeration. The plant does not require frequent watering and can rot if the soil remains damp for an extended period. A mix of sand, perlite, and cactus soil is ideal for the plant. The soil should be mildly acidic with a pH range of 6.0 to 7.5.
Cultivation Methods for Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole
Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole is a fascinating plant that is relatively easy to grow. For optimal cultivation, it needs to be grown in a dry, desert-like environment that mimics its natural habitat. This means that it requires well-draining soil with a low to modest level of nutrients, as well as a lot of sunlight.
When it comes to choosing the right soil, it's best to opt for a commercial cactus mix or make a mix yourself using equal parts of sand, perlite, and peat or coconut coir. Another option is to use a soil mix made exclusively for lithops, which can be found at specialized nurseries or online stores.
Watering Needs for Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole
The watering needs of Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole are unique, and they require a little bit of care to get right. Since they are succulents, they store water in their leaves and do not require much water. Overwatering can be fatal to these plants and may cause them to rot.
The best way to water lithops is to water them sparingly but thoroughly. This means that you should only water them when the soil is completely dry, and when you do water them, be sure to water the soil around them and not directly on the plant. You can use a watering can with a thin spout to help you achieve this. Furthermore, avoid watering them during the winter season when they are in their dormant phase.
Fertilization for Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole
Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole does not require a lot of fertilization because it gets most of its nutrients from the soil. However, if you want to give your lithops a little boost, you can fertilize them with a balanced fertilizer once a month during the growing season. Make sure to dilute the fertilizer to half of the recommended strength to avoid over-fertilizing the plant.
Pruning for Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole
Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole does not require pruning since it is a slow-growing plant with a low, compact growth habit. However, if you notice any dead or dried leaves, you can remove them with a pair of sharp, sterile scissors or tweezers to keep the plant looking neat and tidy. Be sure to avoid damaging the healthy leaves, as they will not grow back.
Propagation of Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole
Lithops fulleri N.E.Br. var. rouxii (de Boer) D.T.Cole, commonly known as pebble plants or living stones, can be propagated by seeds, leaves, or division.
Propagation by seeds
Propagation by seeds is the most common method for Lithops fulleri var. rouxii. Seeds should be sown during the spring in a well-draining soil mix. The seeds should be lightly covered with soil and kept moderately moist. Germination usually starts within 2-4 weeks and can take up to 6 months. Once the plants are large enough to handle, they can be transplanted into individual pots.
Propagation by leaves
Propagation by leaves is a more challenging but interesting method. Leaves can be taken off the plant by gently twisting them from the stem. The leaves should be left to dry for a day or two before planting in a well-draining soil mix. The soil should be kept moist but not too wet. Overwatering can cause the leaves to rot. New plants will start growing from the base in 2-4 weeks.
Propagation by division
Propagation by division is a simple method to increase the number of Lithops fulleri var. rouxii. The plant should be removed from the soil and gently separated into two or more individual plants. Make sure each plant has enough roots and gently plant them in separate pots. Water the plants sparingly until they become established.
Disease and Pest Management for Lithops Fulleri N.E.Br. var. Rouxii (De Boer) D.T.Cole
Lithops fulleri N.E.Br. var. rouxii (De Boer) D.T.Cole, commonly known as Rouxii Living Stones, are unique plants that are relatively easy to care for. However, they are still susceptible to various diseases and pests that can hinder their growth and overall health. Here are some common diseases and pests that may affect Rouxii Living Stones and ways to manage them:
Diseases
Leaf rot: This is a common disease that affects many succulent plants, including Lithops fulleri N.E.Br. var. rouxii. It is caused by fungal or bacterial infections, which can spread rapidly and cause the leaves to turn brown or black. To prevent leaf rot, it is important to avoid overwatering and ensure proper drainage. If you notice any signs of leaf rot, remove the affected leaves and treat the plant with a fungicide or bactericide.
Root rot: Like leaf rot, root rot is also caused by fungal or bacterial infections. The symptoms include soft, mushy roots and discolored leaves. To prevent root rot, make sure that you are not overwatering your plant and that the soil has good drainage. If you suspect root rot, remove the plant from the soil and trim away the affected roots before repotting in fresh soil.
Pests
Mealybugs: These are small, white, cotton-like insects that can infest your Lithops fulleri N.E.Br. var. rouxii. They like to hide in crevices and are difficult to see until they have multiplied in number. The best way to prevent mealybugs is to regularly inspect your plant and wipe it down with a damp cloth or cotton swab to remove any visible pests. If you notice a full-on infestation, you may need to use insecticidal soap or a neem oil solution to eradicate them.
Spider mites: These are tiny arachnids that weave small webs on your plant's leaves. They suck the sap out of the leaves and cause them to turn yellow and fall off. To prevent spider mites, keep the humidity around your plant high and avoid allowing the soil to dry out completely. If you notice spider mites, you can try spraying the plant with water to knock them off, or use an insecticidal soap or miticide to get rid of them.
By being vigilant and taking preventative measures, you can keep your Lithops fulleri N.E.Br. var. rouxii healthy and free of diseases and pests.
