Once the seedlings are large enough, transplant them into their own pots and continue to water regularly.
Disease Management
Hemicarpha micrantha is susceptible to various diseases such as root rot, fungal leaf spots, and rust. Proper cultural management practices can prevent the spread and development of these diseases.
Root rot can be managed by ensuring proper drainage for the plant and avoiding overwatering. If root rot is already present, it is recommended to remove the affected plant parts and replant the remaining healthy parts in fresh soil. Fungal leaf spots can be controlled by removing and destroying infected leaves, improving air circulation, and avoiding overhead irrigation. Rust can be controlled by removing affected leaves and using fungicides as a preventive measure.
Pest Management
Hemicarpha micrantha is also susceptible to various pests such as spider mites, mealybugs, and scale insects. These pests can cause leaf discoloration, wilting, and stunted growth, among others. Proper pest management practices can control their infestation and prevent further damage.
Spider mites can be controlled by regular spraying of water to increase humidity around the plant and using insecticidal soap or neem oil. Mealybugs and scale insects can be manually removed by wiping them off with a cotton swab dipped in rubbing alcohol or neem oil. Insecticidal soap or horticultural oil can also be used as a preventive measure. It is essential to monitor the plant regularly for any signs of infestation and take immediate action to prevent their spread.
