Cultivation of Osteospermum dregei (DC.) Norl. var. reticulatum Norl.
Osteospermum dregei (DC.) Norl. var. reticulatum Norl. is a herbaceous plant that grows up to a height of 0.5m. It is native to South Africa and belongs to the family Asteraceae. The following cultivation methods are advisable when growing this plant:
- It requires well-drained sandy soil with a PH range of 5.5 to 7.5
- Grows best in areas with bright sunlight or partial shade
- Sow the seeds during early spring, either in seed trays or directly in the garden bed. Cover the seed with a thin layer of soil or vermiculite.
- Increase the temperature of the soil to encourage germination by covering it with a transparent plastic cover.
- Germination occurs in less than seven days.
- Transplant the seedlings when they reach a height of 10cm to a well-prepared garden bed or containers with a spacing of about 25cm to 30cm apart.
Watering Needs
To thrive and blossom, Osteospermum dregei (DC.) Norl. var. reticulatum Norl. requires moderate watering. Here are some watering tips:
- Water the plant once or twice a week, especially during the hottest months of the year.
- Check the soil moisture level by inserting your finger an inch into the soil. If the soil is dry, it is an indication that it needs more water.
- Be cautious of overwatering as it may lead to waterlogging of the plant roots, causing them to rot. This plant is not drought tolerant but can tolerate moderate drought conditions.
- As the plant matures, reduce watering as it becomes more established.
Fertilization
Osteospermum dregei (DC.) Norl. var. reticulatum Norl. requires regular fertilization throughout the growing season to boost growth, flowering, and overall performance. Here are some tips for fertilizing:
- Use a balanced fertilizer with an equal proportion of nitrogen, phosphorus, and potassium. A ratio of 20:20:20 is adequate.
- Top-dress the plants with a slow-release granular fertilizer once in three months.
- Heavy feeding with less frequent applications is more beneficial than light feeding with frequent applications.
- Avoid nitrogen-rich fertilizers as they can lead to vegetative growth at the expense of flowering.
- Avoid fertilizing the plant during the winter season as it is in the dormant phase.
Pruning
Pruning helps in maintaining the plant's shape and also encourages more growth and flowering. Here are some tips for pruning Osteospermum dregei (DC.) Norl. var. reticulatum Norl:
- Prune the plant during the early winter months to encourage dense growth during the spring.
- Remove the dead blooms by cutting the stem behind the flower. This process is called deadheading and should be done regularly once the plant starts to blossom.
- Always use clean and disinfected pruners to minimize the risk of infection.
- Trim off any weak or damaged branches to promote the healthy growth of the plant.
- To shape the plant, use a pair of pruners or sharp scissors.
Propagation of Osteospermum dregei (DC.) Norl. var. reticulatum Norl.
