To prune the plant, use a sharp pair of pruning shears and make clean cuts just above the leaf joints. It's essential to avoid cutting off too many leaves or stems at once, as this can lead to stunted growth or other plant stressors. Pruning can be done anytime during the plant's growth season.
Propagation of Hydrocotyle debilis Eckl. & Zeyh.
Hydrocotyle debilis Eckl. & Zeyh. is a resilient and low-maintenance plant that can be easily propagated by a variety of methods:
Seed propagation
Seeds are produced by the plant and can be harvested and stored until the right conditions for growth. The seeds should be sown in a well-prepared bed of seed-raising mix or soil. Daily watering is necessary to ensure the seedlings germinate and grow strong. Seedlings can be transplanted once they have at least four leaves.
Division
Division is the most common method of propagation used by gardeners. It involves dividing plants into smaller sections and replanting them. This can be done by removing the soil around the plant, gently loosening the root ball, and dividing it into smaller sections. Each section should have a healthy leaf and root system. The divided sections can then be planted in new, well-prepared soil, and watered daily.
Cuttings
Cuttings are another method of propagation, which involves taking a stem cutting from a plant and rooting it in a suitable rooting hormone and medium. Cuttings should be taken from vigorous, healthy plants and should be at least 5 cm long. Once cut, they should be immediately placed in a rooting hormone and placed in a well-prepared pot or bed of soil. Careful daily watering is required until the cutting has rooted and is growing well.
Runners
Hydrocotyle debilis Eckl. & Zeyh. produces stolons or runners, which are collections of leaves and roots that spread outwards from the mother plant. Runners can be easily severed from the mother plant and replanted in a suitable medium in a well-prepared bed of soil. Daily watering is required until the runners have taken root and established themselves.
