This plant can tolerate some shade but it grows best when exposed to plenty of sunlight. It is, however, important to protect the plant from intense sunlight during hot afternoons as it can scorch the leaves and stunt growth.
Temperature Requirements
The plant grows best in warm to hot climates and can only survive at temperatures above 10°C. It is, therefore, important to ensure that the plant is grown in areas where the temperature ranges between 18°C to 30°C. Extreme temperatures can negatively impact the plant's growth and development, and in some cases, cause death.
Soil Requirements
Spermacoce princeae (K.Schum.) Verdc. var. mwinilungae Verdc. requires well-draining soils that are rich in organic matter. The plant can thrive in a variety of soils but prefers loamy soil that is slightly acidic. It is important to ensure that the soil is moist but not waterlogged. Poor soil drainage can cause roots to rot and affect the plant's growth and development.
Cultivation methods:
Spermacoce princeae (K.Schum.) Verdc. var. mwinilungae Verdc. is a perennial plant that requires warm temperatures and well-draining soil. It can be propagated by seeds, cuttings, or division of rootstock. Since it prefers light shade, it is best to plant it under trees or in partially shaded areas.
Watering needs:
It is essential to provide adequate water to Spermacoce princeae (K.Schum.) Verdc. var. mwinilungae Verdc. during its growing season. The plant prefers moist soil but can tolerate moderate periods of drought. Water it deeply once a week, but avoid overwatering, as it can lead to root rot.
Fertilization:
The plant can benefit from regular fertilization to maintain its health and flowering. Use a balanced fertilizer, such as 10-10-10, every four to six weeks during the growing season. Avoid applying fertilizers during dormant periods.
Pruning:
Pruning is necessary to maintain the shape and size of the plant and encourage new growth. Use sharp pruning shears to remove any dead, damaged, or diseased branches. Pinch back the tips of the stems to encourage bushy growth. Prune the plant in late winter or early spring before new growth appears.
Propagation of Spermacoce princeae (K.Schum.) Verdc. var. mwinilungae Verdc.
Spermacoce princeae (K.Schum.) Verdc. var. mwinilungae Verdc. can be propagated through various methods, including division, stem cuttings, and seeds.
Division
Division of the plant involves separating the root mass into smaller clumps and planting them separately. This method should be done during the early spring or late fall.
Stem Cuttings
Stem cuttings can be taken in the spring or summer months. The cuttings may be taken from the tip or the middle of the stem. The cuttings should be about 3-4 inches long and need to be dipped in rooting hormone before being placed into a well-draining rooting medium. They should be kept moist, and in about 4-6 weeks, they should start growing roots.
Seeds
Seeds of Spermacoce princeae (K.Schum.) Verdc. var. mwinilungae Verdc. can be sown during the spring in a well-prepared soil bed. The seeds should be lightly covered with soil, kept moist, and placed in an area with indirect sunlight. Germination should occur within a few weeks.
