Light Conditions
Delosperma ashtonii L.Bolus requires full sunlight in order to grow and flourish properly. Therefore, it is best to plant it in locations that receive at least 6-8 hours of direct sunlight each day. In areas with intense heat, it may be necessary to provide some shade during the hottest parts of the day.
Temperature Requirements
Delosperma ashtonii L.Bolus is a resilient plant and can withstand a range of temperatures. It can be grown in USDA hardiness zones 6 through 9. However, it thrives in temperatures ranging from 70-85°F (21-29°C) during the day and 50-55°F (10-13°C) at night. It is important to protect the plant from frost and freezing temperatures, which can be detrimental to its growth and survival.
Soil Requirements
Delosperma ashtonii L.Bolus prefers well-draining, sandy soils that are low in nutrients. The soil should have a neutral to slightly acidic pH level between 6.0 and 7.5. When planting, it is recommended to mix a small amount of compost or sand into the soil to improve drainage. Overwatering or poorly drained soil can cause root rot, which can lead to the demise of the plant. Fertilization is also optional, but if done, it should be kept to a minimum to prevent excessive growth that may cause flopping.
Cultivation Methods
Delosperma ashtonii L.Bolus is a low-growing perennial succulent that thrives in warm, arid climates. It is best grown in a well-drained soil mix that is rich in organic matter. It is also important to ensure that the plant receives full sun for at least six hours a day. When planting, space the plants about 12 inches apart to allow ample room for growth.
Watering Needs
Delosperma ashtonii L.Bolus requires moderate watering during the growing season, but it is important not to overwater. Too much water can cause root rot, so it is best to wait until the soil has dried out completely before watering again. In winter, it is best to water the plant sparingly, only enough to keep the soil from completely drying out.
Fertilization
Delosperma ashtonii L.Bolus benefits from proper fertilization during the growing season. A balanced, water-soluble fertilizer can be applied once a month to help promote healthy growth. It is important not to over-fertilize, as this can lead to leggy growth and poor flowering.
Pruning
Delosperma ashtonii L.Bolus generally requires little to no pruning, but it is important to remove any dead or damaged foliage to promote healthy growth. If the plant becomes too leggy, it can be trimmed back after flowering to encourage bushier growth. Pruning should be done in spring, before new growth appears.
Propagation of Delosperma ashtonii L.Bolus
Delosperma ashtonii L.Bolus is a succulent subshrub that belongs to the Aizoaceae family. This plant is native to South Africa, where it grows in rocky outcrops and along coastal cliffsides. It is a popular garden plant due to its attractive foliage and brightly colored flowers that bloom in summer.
Propagation Methods
There are several ways to propagate Delosperma ashtonii L.Bolus, including:
1. Cuttings
Propagation by cuttings is the most common method used to propagate Delosperma ashtonii L.Bolus. Cuttings can be taken during the growing season when the plant is actively producing new growth. Use sharp, clean scissors or pruning shears to take a cutting that is about 4-6 inches long. Remove the lower leaves from the cutting, leaving only a few at the top. Dip the cut end in rooting hormone powder, and plant it in a well-draining soil mix. Keep the soil moist and in a warm, bright location until roots develop, then transplant the new plant into a larger container.
2. Division
Propagation by division is another method of increasing the number of Delosperma ashtonii L.Bolus plants. This is best done in spring or fall, when the plant is not in active growth. Dig up the entire plant and gently separate the clumps into smaller sections, making sure each section has roots attached. Replant the new sections in a well-draining soil mix, keeping the soil moist until new growth appears.
3. Seeds
Propagation by seeds is also possible, but this method requires more time and patience. Collect seeds from mature plants and sow them in a well-draining seed-starting mix. Keep the soil moist and in a warm, bright location until the seeds germinate. When the seedlings are large enough to handle, transplant them into individual containers, and keep them in a bright location until they are large enough to be planted outdoors.
Overall, Delosperma ashtonii L.Bolus is an easy plant to propagate, and with proper care, it will reward you with bright, showy flowers year after year.
Disease and Pest Management for Delosperma ashtonii L.Bolus
Delosperma ashtonii L.Bolus, commonly known as Ashton's Ice Plant, is susceptible to some pests and diseases just like other plants.

Here is a brief overview of common diseases and pests that can affect Delosperma ashtonii L.Bolus and how to manage them:
Pests that Affect Delosperma ashtonii L.Bolus
1. Spider Mites: These tiny pests often cause yellow leaves and stunted growth in Delosperma ashtonii L.Bolus. The spider mites typically appear on the bottom of the leaves and create webbing between the leaves.
Management: Regular checking of the plants is essential to detect and control spidermite infestation. Regularly wash the leaves with a strong spray of water to keep the plants clean. If the infestation becomes uncontrollable, use insecticidal soap or neem oil to control the pests.
2. Aphids: Aphids are small, pear-shaped insects that are usually light green or black. They suck the sap from the plants and cause the leaves to curl and stunt growth.
Management: Inspect your plants regularly and use a strong spray of water that can knock the aphids off the plants. Alternatively, use insecticidal soap or neem oil or encourage ladybugs to your garden to keep the aphids under check.
Diseases that Affect Delosperma ashtonii L.Bolus
1. Root Rot: Root rot is a common disease caused by fungi in the soil. The disease causes the roots to decay and the plant to wilt and die.
Management: To prevent root rot in Delosperma ashtonii L.Bolus, it is essential to provide well-drained soil and avoid over-watering the plants. Remove the affected plants from the soil immediately as the disease is highly contagious.
2. Leaf Spot: Leaf spot disease is a fungal infection that causes brown spots on the leaves. The leaves turn yellow and fall off if the disease is severe.
Management: Cut off and destroy the affected leaves to control the spread of the disease. Do not water the plants from above, as this can spread the disease. Spray copper fungicides regularly to prevent infection.
By managing pests and diseases on Delosperma ashtonii L.Bolus, you can maintain their health and keep them blooming for years.
