Temperature Requirements
Native to South Africa, Putterlickia retrospinosa A.E.van Wyk & Mostert can tolerate a wide range of temperatures. It thrives best in temperatures ranging from 20-30 °C (68-86 °F). It can tolerate hot and dry conditions but is not frost tolerant. As such, it should be protected from frost and cold temperatures.
Soil Requirements
Putterlickia retrospinosa A.E.van Wyk & Mostert grows best in well-draining soils with a neutral to slightly acidic pH level. It can tolerate a wide range of soil types, including clay, loam, and sandy soils, but requires good drainage to prevent waterlogging.

Cultivation methods for Putterlickia retrospinosa
Putterlickia retrospinosa is an excellent plant for cultivation in gardens due to its attractive appearance. The plant requires well-drained soils with moderate or high fertility levels. In gardens, the Putterlickia retrospinosa can be grown as a shrub or small tree. It is perfect for home gardens, and can also be grown in large containers for indoor cultivation.
Watering needs of Putterlickia retrospinosa
The watering needs of Putterlickia retrospinosa vary according to climate and soil type. When grown in wet or humid areas, the plant does not require frequent watering, as it can survive well with natural rainfall. However, during dry seasons, the plant requires more frequent watering to ensure it stays healthy. It is advisable to water it at room temperature to prevent shock to the plant roots. To keep the soil moist, it is recommended to mulch the plant regularly.
Fertilizing Putterlickia retrospinosa
Putterlickia retrospinosa plants thrive best with regular fertilization. During the growing season, the plant requires a balanced fertilizer with sufficient potassium, nitrogen and phosphorus. Fertilize the plant at least once monthly, and ensure that the fertilizer is well-watered into the soil. It is best to stop fertilizing during the winter season as the plant enters dormancy, and fertilizer can cause damage to the plant.
Pruning of Putterlickia retrospinosa
Pruning Putterlickia retrospinosa is important for maintaining its shape and size, and to enhance its appearance. The best time to prune the plant is during the winter or early spring seasons. It is advisable to prune back any dead or damaged branches, and thin out the plant to allow light and air to penetrate the foliage. It is best to use sharp, clean tools for pruning to avoid transmitting diseases to the plant. Regular pruning will help to maintain the plant's vigor and health.
Propagation of Putterlickia retrospinosa
Putterlickia retrospinosa, commonly known as "veldt grape," is a deciduous plant that belongs to the family Vitaceae. It is endemic to the western regions of South Africa, and its habitat is characterized by dry, rocky slopes and cliffs. The plant has a unique appearance, with multi-branched stems forming a dense, spikey tangle of twigs and leaves.
Propagation Methods
There are two primary methods of propagating Putterlickia retrospinosa: by seed and by cuttings.
Propagation by seed: Putterlickia retrospinosa produces small, round berries that contain seeds. These berries should be harvested when they turn black and slightly soft. After harvesting, the berries' pulp should be removed by hand, and the seeds should be washed to remove any remaining pulp.
The seeds should be planted in a well-draining soil mixture with a pH range of 5.5 to 7.5. The seeds should be barely covered with soil and kept moist, but not wet, until they germinate. Germination usually occurs within three to six weeks.
Propagation by cuttings: Cuttings from Putterlickia retrospinosa can be taken during the plant's dormant season, which is typically between May and July.
The cuttings should be taken from the plant's woody stems, with each cutting being approximately 20 to 30 cm long and containing at least one node. The bottom of the cutting should be treated with a rooting hormone, and the cutting should be planted in a well-draining soil mixture. The soil should be kept moist, and the cutting should be kept in a shady area until it has rooted.
Both methods of propagation have a relatively high success rate, and once established, Putterlickia retrospinosa requires little maintenance.
Disease and Pest Management for Putterlickia Retrospinosa
Putterlickia retrospinosa is a resilient plant that can tolerate harsh weather and soil conditions. However, like any plant, it is susceptible to diseases and pests that can harm its growth and health. Here are some common diseases and pests that might affect Putterlickia retrospinosa and ways to manage them.
Common Diseases
Putterlickia retrospinosa may be affected by various fungal and bacterial diseases. Powdery mildew is a common fungal disease that appears as a white or grayish powder on the leaves and stems. This disease thrives in humid conditions, and overcrowding and poor air circulation can make it worse. To manage powdery mildew, remove the affected parts and spray the plant with a fungicide. Good air circulation and proper spacing can help prevent an outbreak.
Anthrone canker is another fungal disease that affects the stems and branches of Putterlickia retrospinosa. This disease causes the bark to crack, and the tissues underneath to turn brown. To manage anthrone canker, prune the affected parts and spray the plant with a fungicide. Avoid overhead watering, as it can spread the disease.
Bacterial leaf spot is a common bacterial disease that appears as circular, water-soaked lesions on the leaves. This disease thrives in wet conditions and can spread rapidly if left untreated. To manage bacterial leaf spot, remove the affected leaves and apply a copper-based fungicide. Avoid overhead watering and improve air circulation around the plant.
Common Pests
Putterlickia retrospinosa may also be affected by various insects and pests. Spider mites are common pests that feed on the plant's sap, causing the leaves to appear stippled and yellowed. These pests thrive in hot and dry conditions, and overcrowding can make an infestation worse. To manage spider mites, spray the plant with a miticide and improve the plant's overall health through proper watering and fertilization.
Scale insects are another common pest that can affect Putterlickia retrospinosa. These pests appear as small, hard bumps on the plant's leaves and stems and can cause stunted growth and yellowed leaves. To manage scale insects, gently scrub the plant with a soft-bristled brush and insecticidal soap. Repeat treatments may be required to fully eradicate the pests.
Caterpillars and other chewing insects can also pose a threat to Putterlickia retrospinosa. These pests feed on the leaves and can cause significant damage if left unchecked. To manage caterpillars and other chewing insects, pick off the affected leaves and apply an insecticide if necessary.
By monitoring Putterlickia retrospinosa for signs of disease and pests and promptly addressing any issues, you can help keep this plant healthy and vibrant. It's also essential to maintain good plant hygiene, proper spacing, air circulation, and watering practices to prevent disease and pest problems from arising in the first place.
