Fertilization of Hydrocotyle Littoralis Eckl. & Zeyh.
Fertilization is essential for the healthy growth of Hydrocotyle Littoralis Eckl. & Zeyh. plants. Houseplant fertilizers or liquid fertilizers diluted in water can be used every two weeks during the growing season, which is in spring and summer. It is recommended to avoid fertilizing them during the dormant season.
Pruning of Hydrocotyle Littoralis Eckl. & Zeyh.
Pruning is necessary to keep the Hydrocotyle Littoralis Eckl. & Zeyh. plants healthy and lush. The plant should be trimmed regularly to remove any yellow or dead leaves, especially during the growing season.

Propagation of Hydrocotyle littoralis Eckl. & Zeyh.
Hydrocotyle littoralis Eckl. & Zeyh. can be propagated through seeds, division, and stem cuttings.
Propagation by Seeds
Seeds of Hydrocotyle littoralis Eckl. & Zeyh. can be collected and sown in a well-draining soil mixture. The seeds need light to germinate, so they should be sown on the surface and pressed down gently. They should be kept moist and in a warm and bright area. Germination usually occurs within two to three weeks.
Propagation by Division
The plant can also be propagated by division. This method involves carefully separating the plant into smaller pieces, making sure that each piece has a good amount of roots and leaves. The division should be done during the plants' dormant period in the spring or fall. The new divisions should be replanted in well-draining soil and kept moist until they have established themselves.
Propagation by Stem Cuttings
Propagation by stem cuttings is also possible. The cuttings should be taken from healthy and mature plants. A stem with a few leaves and roots should be cut from the mother plant and immediately transplanted to a pot with well-draining soil. The cuttings should be kept moist and in a warm, bright area until they have established themselves.
Disease Management:
Hydrocotyle littoralis Eckl. & Zeyh. is susceptible to a variety of diseases, including fungal, bacterial, and viral infections. Early detection and control are critical to minimize damage to the plant. The following are some common diseases and their management strategies:
1. Leaf Spot:
Leaf spot is a fungal disease that affects the leaves of the plant. The spots appear as small, brown areas, with a yellow halo around them. To control leaf spot, remove infected leaves and debris from the plant's vicinity. Apply a fungicide according to the manufacturer's instructions to prevent the spread of the disease.
2. Powdery Mildew:
Powdery mildew is a fungal disease that typically affects the plant's leaves, causing a white, powdery coating to appear on them. To avoid powdery mildew, provide adequate ventilation to the plant, as high humidity favors its growth. Use a fungicide to control the disease.
3. Root Rot:
Root rot is a fungal disease that affects the plant's roots. Overwatering or poorly drained soil may lead to root rot. To prevent root rot, ensure that the plant's soil is well-draining, and avoid overwatering. Remove infected plants promptly and avoid planting the same crop in the same area next planting season.
Pest Management:
Several pests can affect Hydrocotyle littoralis Eckl. & Zeyh., including insects, mites, and snails. The following are some common pests and their management:
1. Aphids:
Aphids are common pests that suck sap from the plant, resulting in weakened, stunted growth. To control aphids, use insecticidal soap or horticultural oil. Alternatively, use a steady stream of water to wash off the aphids.
2. Spider Mites:
Spider mites are tiny pests that feed on the plant's sap, causing the leaves to dry and turn brown. Evidence of spider mites includes fine webs or discoloration of the leaves. To manage spider mites, use a miticide, making sure to follow instructions carefully.
3. Snails and Slugs:
Snails and slugs can cause significant damage to Hydrocotyle littoralis Eckl. & Zeyh. by feeding on the leaves. To control these pests, handpick snails and slugs at night or early in the morning when they are more active. Alternatively, use baits or copper strips to deter them from the plants.
