However, due to its threatened status and restricted distribution in the wild, it is important to ensure that plants in cultivation are not sourced from the wild. This plant is also highly sensitive to disturbance and habitat destruction, and any unauthorized collection or unauthorized operation on this plant is punishable by law.
Light Requirements
The Dudleya gnoma S. McCabe requires full sun to light shade with partial shade for optimal growth. It can be found in open areas, rocky outcrops, and coastal bluffs which implies they require a certain level of light. It is important to provide them enough sunlight to promote flower blooming, but avoid excessive light to prevent burning the leaves of the plant.
Temperature Requirements

It can withstand temperatures ranging from 10° to 40°C, making it a great succulent plant for many regions. Caregivers should consider temperature when choosing the best location for the plant to avoid stressing it and interfering with its growth process.
Soil Requirements
Dudleya gnoma prefers well-draining, rocky soils of volcanic origin. The plant requires soil with a pH range of 6.0 to 8.0, which is almost neutral. It also requires some organic matter in the soil for optimal growth. Gardeners who desire to cultivate the plant in containers must use a cactus soil mix with added perlite or pumice to encourage quick drainage. The addition of sand also increases drainage in a potting mixture of Dudleya gnoma S. McCabe.
Cultivation Methods for Dudleya gnoma S. McCabe
Dudleya gnoma S. McCabe, commonly known as Gnome Dudleya, can be grown in containers or outdoors in well-draining soil under full sun to partial shade. The plant prefers coastal conditions and tolerates mild frost and drought.
When grown in containers, use a standard potting mix amended with gritty materials or perlite to improve drainage. Repotting should be done every two to three years, or when the plant outgrows its container.
Watering Needs for Dudleya gnoma S. McCabe
Dudleya gnoma S. McCabe is drought-tolerant but appreciates occasional watering during the growing season. Water the plant thoroughly when the soil has dried out completely. Overwatering can lead to root rot and should be avoided.
In areas with high humidity, refrain from watering the leaves of the plant as it may promote fungal growth.
Fertilization of Dudleya gnoma S. McCabe
Dudleya gnoma S. McCabe does not require regular fertilization and can thrive in nutrient-poor soil. Over-fertilizing can lead to leggy growth, reduced drought tolerance, and damage to the plant.
If the plant appears stunted or yellow, apply a balanced fertilizer once a month during the growing season. Follow the instructions on the fertilizer package and dilute the solution to half-strength.
Pruning Dudleya gnoma S. McCabe
Dudleya gnoma S. McCabe does not require regular pruning. However, removing spent leaves and flower stems can improve the appearance of the plant and prevent pest infestations.
To prune the plant, use clean, sharp scissors, and cut the leaf or stem as near to the base as possible. Avoid damaging the remaining foliage or stem of the plant.
Propagation of Dudleya gnoma S. McCabe
Dudleya gnoma S. McCabe is a unique succulent plant, native to Baja California, Mexico. Propagation of this plant can be done through various methods, including:
Seed Propagation
The first method of propagation for Dudleya gnoma S. McCabe is through seed. Seeds can be collected from the plant after flowering in the late summer. These seeds can be sown in a well-draining cactus mix with perlite or sand. It is recommended to keep the soil moist but not wet during the germination phase. Seeds will typically germinate in 2-4 weeks at temperatures between 60-70°F. Once the seedlings have grown about 1 inch tall, they can be transplanted to individual pots.
Stem Cuttings Propagation
Another propagation method for Dudleya gnoma S. McCabe is through stem cuttings. The best time to take stem cuttings is during the summer months. Select a healthy stem and cut it just below a node. Let the cutting callus over for a few days before planting it in well-draining cactus mix with perlite or sand. Keep it in bright, indirect light and water sparingly until roots start to develop. Once the cutting has rooted and has started to grow, it can be transplanted into individual pots.
Leaf Cuttings Propagation
A third propagation method for Dudleya gnoma S. McCabe is through leaf cuttings. Select a healthy leaf and gently pull it off the stem. Allow the leaf to dry and callus over for a few days before planting it in well-draining cactus mix with perlite or sand. Water sparingly until roots start to develop and a new rosette of leaves appears. Once the new plant has established roots, it can be transplanted into individual pots.
Propagation of Dudleya gnoma S. McCabe can be a fun and rewarding process for plant enthusiasts. With proper care and attention, new plants can be propagated from seeds, stem cuttings, or leaf cuttings.
Disease and Pest Management for Dudleya gnoma S. McCabe
Dudleya gnoma S. McCabe, also known as Laguna Beach Liveforever, is a beautiful succulent native to California. This plant is easy to care for but is susceptible to a few diseases and pests that gardeners should be aware of. With proper maintenance, it is possible to prevent these issues from causing significant damage, helping your plant to thrive for years to come.
Common Diseases
One of the most common diseases that affect Dudleya gnoma is root rot. This fungal disease thrives in damp soil and can cause the plant's roots to rot away, making it difficult for the plant to absorb nutrients and water adequately. To prevent root rot, ensure that your plant is not overwatered and has excellent drainage. If you notice your plant's leaves turning yellow or brown and appearing wilted or droopy, it may be suffering from root rot. To manage this disease, reduce watering and improve soil drainage.
Another disease that can affect Dudleya gnoma is leaf spot, a fungal infection that causes small brown or black spots on the plant's leaves. This disease can spread quickly and cause extensive damage, so it's essential to address it promptly. To manage leaf spot, remove any infected leaves and prune away affected areas. Additionally, avoid getting the plant's foliage wet when watering and ensure that it has adequate airflow around it.
Common Pests
Dudleya gnoma is susceptible to a few pests, including mealybugs and spider mites. Mealybugs are small, white insects that feed on the plant's sap, causing it to weaken and become susceptible to other diseases. Spider mites, on the other hand, are tiny arachnids that spin webs and suck the plant's juices. Both of these pests can be managed using an insecticidal soap or neem oil.
Scale insects are another common pest that affects Dudleya gnoma. These pests appear as small, round bumps on the plant's foliage and can cause significant damage. To manage scale insects, prune away infected areas and use a horticultural oil to suffocate any remaining pests on the plant.
With regular inspections and proper care, you can prevent many diseases and pests from harming your Dudleya gnoma S. McCabe. Removing any damaged or infected foliage and maintaining excellent growing conditions will help to keep your plant healthy and thriving for years to come.
