Light requirements
Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. requires full sun exposure to grow properly. It is recommended to place the plant in a south-facing direction to ensure maximum sunlight exposure. Without adequate sunlight, the plant will not bloom correctly and may experience slow growth.
Temperature requirements
The plant can tolerate high temperatures without getting damaged, but the ideal temperature range for growth is between 60 - 68°F (15.5 - 20°C). Temperatures above 75°F (24°C) might lead to plant stress, which may result in decreased growth and flowering. M. croceum var. flavocroceum is a frost-tender plant and can quickly die if it is exposed to frost.
Soil requirements
The soil should be well-draining, sandy, and slightly acidic with a pH level between 5.6 and 6.5 for optimal growth. Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. prefers soil that is rich in nutrients but not too fertile or clay-like. It is essential to avoid overwatering or waterlogging the soil to prevent root rot or fungal diseases.
Cultivation Methods
Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. prefers to grow in a sandy, well-draining soil mix. It thrives in dry and hot environments, so it should be grown in full sun. Ensure that the plant receives at least 6 hours of direct sunlight per day. Additionally, it can be grown outdoors or in containers, depending on your preference.
When planting, make sure that the roots of the plant are not disturbed. Water your plant regularly during the establishment period.
Watering Needs
This plant prefers to be watered deeply but infrequently. It can tolerate drought to an extent but should be watered immediately when the soil is dry to the touch. This plant is prone to root rot, so it is essential to avoid overwatering. Watering it once a week during the growing season is sufficient, while during winter, water it once every 15 days.
Fertilization
This plant's fertilization schedule should be monthly during the growing season. Use a low-nitrogen fertilizer every four weeks during the growing months, from spring to summer. This will help in supporting the various metabolic processes of the plant and ensure that it blooms brightly and healthily.
Pruning
Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. is not a demanding plant when it comes to pruning. Pruning it will boost its productivity as the plant can focus on new growth. It would be best to trim back the plant in the early spring to remove any carefully yellowed leaves or stems. However, remember to use sterilized shears to avoid spreading plant diseases. Additionally, removing spent blooms and dead flowers encourages the growth of new buds, leading to a prolonged blooming period.
Propagation of Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC.
Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. is commonly known as yellow ice plant or golden carpet. It is a popular ornamental plant due to its bright yellow flowers and carpet-like growth habit. The plant can be propagated through various methods such as seed propagation, stem cuttings, and division.
Seed propagation
The easiest and most common method of propagating Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. is through seed propagation. The seeds should be collected after the plant has finished flowering and the seed pods have turned brown. The seed pods can be gently crushed to extract the seeds. The seeds should be sown in a well-draining soil mix and kept moist. Germination occurs within 7-10 days. Once the seedlings have developed several leaves, they can be transplanted to their final growing location.
Stem cuttings
Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. can also be propagated through stem cuttings. The cuttings should be taken from the plant's healthy, non-flowering stems. The stems should be cut around 7-10 cm in length and stripped of their lower leaves. The cuttings should be allowed to callous over for a few days before being planted in a well-draining soil mix. They should be kept moist and in a shaded area until they form roots, which typically takes around 3-4 weeks. Once the cuttings have rooted, they can be transplanted to their final growing location.
Division
Finally, Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. can be propagated through division, which is typically done during the spring or fall. The plant should be lifted from the soil, and the root crown should be carefully divided into smaller sections, each with a healthy growth point. The divided sections should be replanted in a well-draining soil mix and kept moist. They should be kept in a shaded area until they establish roots, which typically takes around 3-4 weeks.
Disease Management:
Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. has the potential to be affected by several diseases throughout its growth cycle. The following are a few common diseases to monitor and manage:
- Root Rot: Overwatering or poor drainage can cause root rot disease in the plant. Use well-draining soil and avoid overwatering to prevent this disease.
- Grey Mould: This disease occurs due to fungal growth, mainly in humid conditions or overcrowding of plants. Proper air circulation, adequate spacing between plants, and regular cleaning of the surrounding environment can prevent grey mould.
- Viral Infections: Viral infections can cause mosaic patterns on the leaves. Since viruses cannot be treated, it is essential to maintain proper hygiene by cleaning tools and equipment while handling the plant.
Pest Management:
Mesembryanthemum croceum Jacq. var. flavocroceum (Haw.) DC. is relatively resistant to pest infestations. However, the following are a few common pests that may affect the plant:
- Spider Mites: These tiny pests suck the sap from the leaves, which results in stunted growth and yellowing of leaves. Regularly inspect the underside of the leaves, and if infested, use insecticidal soap or neem oil to eliminate the spider mites.
- Mealybugs: Mealybugs affect the plant by sucking the sap and producing a white waxy substance on the leaves. Prune the infested leaves, and use neem oil or insecticidal soap to prevent further infestation of the plant.
- Thrips: Thrips damage the plant by feeding on sap, which results in brown spots on the leaves. Use insecticidal soap or neem oil to control thrips' population on the plant.
