Light Requirements
Spermacoce tenuior L. var. tenuior grows well in full to partial sunlight. It requires at least 4-6 hours of direct sunlight each day to thrive. However, it can also grow in shaded areas, but the plant may not flower as profusely compared to those grown in full sunlight.
Temperature Requirements
The ideal temperature range for growing Spermacoce tenuior L. var. tenuior is between 20-30°C (68-86°F). The plant does not tolerate frost and can be damaged if the temperature falls below 10°C (50°F). On the other hand, high temperatures above 35°C (95°F) can lead to wilting and plant stress. Therefore, it is crucial to plant the species during the right season or provide the necessary protection during harsh weather conditions.
Soil Requirements
Spermacoce tenuior L. var. tenuior favors well-draining, fertile soils rich in organic matter. The plant will not grow well in waterlogged soils, as this can cause the roots to rot. The ideal soil pH range for this species is 6.0-7.5. Adding compost or manure to the soil can help improve fertility and drainage. Additionally, regular watering is essential to keep the soil moist but not waterlogged.
Cultivation Methods
Spermacoce tenuior L. var. tenuior is native to tropical regions and grows best in warm temperatures. The plant requires well-drained soil and can tolerate a wide range of soil types, from sandy to clay soil. It can be propagated from seeds or cuttings. If propagated from seeds, they should be sowed in a prepared bed or potting mix and kept moist until they germinate. In case of propagation by cuttings, they should be taken from healthy plants and placed in a rooting hormone and then planted in the soil or a potting mix.
Watering Needs
Spermacoce tenuior L. var. tenuior requires regular watering to flourish, especially during the growing season. It is important to ensure that the soil is well-drained and does not become waterlogged. Overwatering can lead to root rot and cause the plant to die. It is best to water the plant early in the morning or late in the evening when the temperatures are cooler and the water is less likely to evaporate quickly.
Fertilization
Spermacoce tenuior L. var. tenuior benefits from a balanced fertilizer during the growing season. A slow-release fertilizer is recommended to avoid overfeeding the plant. The plant can also benefit from organic fertilizers such as compost or manure. It is important to follow the instructions on the fertilizer label to avoid overfeeding or burning the plant. Fertilization can be done once every two months or as per the fertilizer’s instruction.
Pruning
Pruning of Spermacoce tenuior L. var. tenuior is an important part of its maintenance. The plant should be pruned regularly to control its size and encourage bushy growth. Pruning can also be done to remove dead or diseased parts of the plant. It is best to prune the plant after the flowering season to avoid removing new buds. The plant can be pruned using pruning shears or scissors. It is important to use clean tools to avoid the spread of diseases.
Propagation of Spermacoce tenuior L. var. tenuior
Spermacoce tenuior L. var. tenuior can be propagated both sexually and asexually.
Sexual Propagation
The seeds of Spermacoce tenuior L. var. tenuior can be used for sexual propagation. The plant produces small, brown, ovoid seeds, which germinate readily and grow quickly. The seeds should be collected when they are fully mature, and sown in a prepared seed bed. The seed bed should be kept moist, but not waterlogged, until the seeds germinate. It usually takes about 2 to 3 weeks for the seeds to germinate. Once the seedlings are about 2 to 3 months old, they can be transplanted into individual pots.
Asexual Propagation
Spermacoce tenuior L. var. tenuior can be propagated asexually using stem cuttings. The cuttings should be taken from the tender, new growth of the plant. The cuttings should be about 10 to 15 cm long, and should have at least 2 to 3 nodes. The bottom of the stem should be stripped of its leaves, so that it can be inserted into the rooting medium. The cuttings should be dipped into a rooting hormone, and then inserted into a well-draining rooting medium. The rooting medium should be kept moist, but not waterlogged. The cuttings should root within 3 to 4 weeks. Once the cuttings have rooted, they can be transplanted into individual pots.
