Light Requirements
Sida subrotunda Hochst. typically grows well in full sun to partial shade. It prefers a location with bright, indirect light and can tolerate direct sunlight for a few hours each day. In low-light conditions, the plant may not grow as quickly and may become leggy.
Temperature Requirements
Sida subrotunda Hochst. is a warm-season plant and prefers warm temperatures. It grows best in areas with temperatures ranging from 20-35°C. Temperatures below 15°C can cause the plant's growth to slow down or stop altogether. Frost and cold temperatures can be fatal to this plant.
Soil Requirements
The plant prefers well-draining soils that are rich in nutrients and organic matter. A pH ranging from 6.5-7.5 is ideal and the soil should not be highly alkaline or acidic. Sida subrotunda Hochst. can tolerate a wide range of soil textures, from sandy to clay soils, but prefers a loamy soil. The plant does not tolerate waterlogged soils and can suffer from root rot if the roots are constantly wet.
Cultivation methods for Sida subrotunda Hochst.
Sida subrotunda Hochst. is a perennial plant that can grow up to two meters in height. It is best grown in full sun, but it can also grow in partial shade. This plant is adaptable to various soil types, including clay, loam, and sandy soils, but it prefers well-draining soil. Start by selecting a well-draining and nutrient-rich soil mix. Plant the seeds one inch deep and keep the soil moist until germination.
Watering needs for Sida subrotunda Hochst.
Sida subrotunda Hochst. requires regular watering, especially during the first few months of growth. Water the plant thoroughly once per week or more frequently during hot weather conditions. Ensure the soil consistently stays moist, but avoid overwatering as it can lead to root rot.
Fertilization for Sida subrotunda Hochst.
Fertilize Sida subrotunda Hochst. once every two to three months during the growing season. Use a balanced fertilizer with an NPK ratio of 10-10-10. Apply the fertilizer around the base of the plant and water it immediately.
Pruning Sida subrotunda Hochst.
Pruning should be done to maintain the shape and size of Sida subrotunda Hochst. Cut back the plant by up to one-third of its size in early spring before new growth begins. Remove any dead or diseased foliage as they appear. Additionally, pinching the tips of the stems can promote bushier growth and encourage more flower formation.
Propagation of Sida subrotunda Hochst.
Propagating Sida subrotunda Hochst. can be done through seed propagation or vegetative means.
Seed Propagation
Seeds of Sida subrotunda Hochst. can be collected from matured fruits. The collected seeds must be dried and cleaned before planting. It is best to plant the seeds during the rainy season.
The seeds can be planted directly in the soil or in a nursery. If planting in a nursery, seedlings can be transferred to the field after 4-6 weeks.
It is important to provide adequate moisture until the plants are established. Weeds must also be controlled to prevent competition for nutrients.
Vegetative Propagation
Sida subrotunda Hochst. can also be propagated through vegetative means. Vegetative propagation can be done through stem cuttings or root cuttings.
For stem cuttings, select healthy stems and cut them into 6-8 inch pieces. Remove the leaves from the lower half of the stem cutting. The stem cutting can be dipped in rooting hormone and then planted in a moist potting mix. Keep the cutting in a shaded area and provide adequate moisture until roots develop.
For root cuttings, select healthy roots and cut them into 1-2 inch pieces. Plant the root cuttings in a moist potting mix and keep them in a shaded area. Adequate moisture must be provided until roots and shoots develop.
Overall, Sida subrotunda Hochst. can be propagated successfully through both seed and vegetative means. Proper care must be provided to ensure successful establishment and growth of the plants.
Disease and Pest Management for Sida subrotunda Hochst.
