To start growing Lotononis densa (Thunb.) Harv. subsp. congesta B.-E.van Wyk, plant the seedlings in a well-prepared soil bed or pot. Make sure the soil is well-drained, and water the soils after planting the seedlings. After a few weeks, start fertilizing as explained below.
Watering Needs for Lotononis Densa (Thunb.) Harv. Subsp. Congesta B.-E.Van Wyk
Lotononis densa (Thunb.) Harv. subsp. congesta B.-E.van Wyk tolerates drought conditions. However, for optimal growth, the plant requires adequate water. Water the plants deeply once a week or slightly more often if they are grown in a pot.
Don't overwater the plant, as too much water may promote root rotting and damage the plant. Always ensure that the soil has good drainage to prevent waterlogging.
Fertilization for Lotononis Densa (Thunb.) Harv. Subsp. Congesta B.-E.Van Wyk
Fertilizers are essential for the optimal growth of Lotononis densa (Thunb.) Harv. subsp. congesta B.-E.van Wyk. Use a balanced fertilizer with an N-P-K ratio of 10-10-10, and fertilize the plant twice a month during the growing season.
Ensure that the fertilizer is applied according to the instructions provided by the manufacturer. Avoid over-fertilizing as it may damage the plant.
Pruning Lotononis Densa (Thunb.) Harv. Subsp. Congesta B.-E.Van Wyk
Pruning Lotononis densa (Thunb.) Harv. subsp. congesta B.-E.van Wyk is not mandatory. However, trimming the plant occasionally can promote bushiness and produce more flowers.
Use a clean and sharp pair of pruning shears, and cut the stem just above a node to encourage lateral growth. Make cuts at an angle of 45 degrees to prevent water accumulation on the cut surface. Prune the plant during the early spring before new growth appears.
Propagation of Lotononis densa subsp. congesta B.-E.van Wyk
Lotononis densa subsp. congesta B.- E.van Wyk is mainly propagated through seeds, but it can also be propagated through vegetative means.
Seed Propagation
The plant produces seeds that can be collected and sown directly. The best time to collect the seeds is when the pods are beginning to dry, and the seeds are turning brown. The seeds should be dried and stored in a cool, dry place before sowing. Before planting, the seeds can be scarified to break the hard outer shell and improve germination rates. This can be done by rubbing the seeds with abrasive paper or boiling them in water for a few minutes before soaking them overnight. The seeds should then be sown in a well-draining seedling mix, covered lightly with soil, and kept moist. Germination generally occurs within 2-4 weeks, and the seedlings can be transplanted after they have developed a few true leaves.
Vegetative Propagation
Lotononis densa subsp. congesta B.-E.van Wyk can also be propagated through stem cuttings, but the success rate of this method is relatively low. The cuttings should be taken from healthy plants during the growing season when the plant is actively growing. The cuttings should be approximately 10-15 cm long and should be taken from the current year's growth. The cuttings should be dipped in rooting hormone and planted in a well-draining rooting mix. They should be kept in a moist environment and provided with bottom heat to encourage rooting. It may take several weeks to several months for the cuttings to root, and not all cuttings will be successful. Once the cuttings have rooted and produced new growth, they can be transplanted into individual pots.
Disease Management:
Lotononis densa is generally resistant to most plant diseases. However, it is susceptible to fungal leaf spots, which appear as circular lesions on the leaves. To manage this disease, remove infected leaves and stems and dispose of them properly. Avoid overhead irrigation, as this can spread fungal spores. Apply a fungicide according to the instructions on the label.
Pest Management:
The most common pests that affect Lotononis densa are aphids and spider mites. These pests suck sap from the leaves, causing them to turn yellow and ultimately leading to leaf drop. To manage these pests, remove affected leaves and apply a neem oil spray. Neem oil is a natural insecticide that is effective against a wide range of pests but is safer for the environment than chemical pesticides.
