It is essential to plant the seeds in a sunny area where they can receive at least six hours of sunlight each day. Avoid planting this plant in areas with stagnant water.
Plant the seeds at least 1 cm deep and 15 cm apart. The plant grows well in well-drained soil. Water the newly planted seedlings twice a day for the first few weeks or when the soil feels dry. The Gazania lichtensteinii Less. plant is best grown from seeds which should be sown in well-draining soil.
Watering needs
Gazania lichtensteinii Less. is a drought-resistant plant, but it requires water to establish itself. Water the plant frequently for the first few weeks as it grows. Once the plant is established, you can reduce the frequency of watering.
Water the plant every two weeks or when the soil feels dry. Overwatering can cause yellowing of leaves, root rot, and other damages. To avoid overwatering, ensure that the soil is well-drained to prevent the accumulation of stagnant water.
Fertilization
The Gazania lichtensteinii Less. plant grows well in nutrient-rich soil. It is essential to apply fertilizers to boost the plant's growth and blooming. Fertilize the plant using a balanced, slow-release fertilizer every four to six weeks. Avoid over-fertilizing to prevent damage.
Apply the fertilizer around the plant's outer edge to avoid direct contact with the plant's roots that can lead to chemical burns. Water the plant after applying the fertilizer to distribute the nutrients to the plant's roots.
Pruning needs
Gazania lichtensteinii Less. requires minimal pruning regularly. Pinch back the tips of the plant to promote bushier growth. Deadhead the spent blooms regularly to encourage new flowers to grow. Prune the severely overgrown or damaged section of the plant, and ensure that you cut the stem entirely without leaving a stub.
Prune the plant when it is dormant in the winter to rejuvenate the plant for healthier growth in the following growing season. Use sharp pruning shears to avoid crushing or damaging the plant's stems when pruning.
Propagation of Gazania lichtensteinii Less.
Gazania lichtensteinii Less. is a fast-spreading plant that is easily propagated through both sexual and asexual methods.
Sexual Propagation
When propagated sexually, Gazania lichtensteinii Less. can be grown from seeds. The seeds are usually obtained by collecting the dried flowers of the plant. After collecting the flowers, the seeds are removed by threshing or rubbing. They can then be sown in a nursery or directly into the garden soil. The ideal time to sow the seeds is during the warm weather, after the last frost. The seeds should be sown at a depth of 2-3 cm and watered regularly until germination, which usually takes about 10-12 days.
Asexual Propagation
Gazania lichtensteinii Less. can also be propagated asexually through different methods. The most commonly used method is vegetative propagation, which involves taking cuttings from a mature plant and growing them to form new plants.
The cuttings should be taken from the basal shoots, which are young and tender stems, and should be free from pests and diseases. The cuttings should be about 8-10 cm long and should include at least two nodes. The leaves on the lower part of the stem should be removed, leaving only the top few leaves. The cuttings should be dipped in rooting hormone to encourage faster root growth. They can then be planted in a rooting medium, such as sand or perlite and kept in a warm, humid place until roots develop, which usually takes about 2-3 weeks.
Another asexual propagation method that can be used for Gazania lichtensteinii Less is division. This method involves separating the plant into smaller sections and planting them separately. This is usually done when the plant has become too large and needs to be divided to promote growth and better flower production. The division should be done during the spring or fall. The plant should be dug out of the soil and the root system should be carefully separated into smaller sections, each containing several stems. The sections can then be planted in separate holes, watered and left to grow in a warm, sunny place.
