Stem cuttings: The stem cuttings should be taken from a healthy plant, and each cutting should be approximately 5 cm long and should have at least two nodes. The cuttings are planted in well-draining soil, preferably in a greenhouse, and should be irrigated regularly. The cuttings will start to root in 3-4 weeks, and transplanting can be done after 10 weeks.
Division of the rhizome: The rhizomes are dug up and divided into several pieces, making sure each division has at least one shoot and a few roots. The rhizomes are then planted in a well-draining soil mix, ensuring that the soil is moist. Transplanting can be done after about 2-3 weeks.
Propagation of Gratiola parviflora Roxb. through seeds is also possible. The seeds should be collected when the capsules dry up and are ready to burst. The seeds should be sown shallowly in a tray of well-draining soil and should be kept moist. Germination will occur in about 2-3 weeks, and the seedlings can be transplanted after 6-7 weeks.
In conclusion, the propagation of Gratiola parviflora Roxb. is easy through vegetative or seed propagation. The methods described above will ensure a successful propagation of the plant, which can be used for various medicinal purposes.

Common Pests
Gratiola parviflora Roxb. is also susceptible to several pests, including:
- Aphids: These are small, soft-bodied insects that feed on plant sap and excrete a sticky substance called honeydew. They can be managed by using insecticidal soap or neem oil.
- Spider Mites: These are tiny arachnids that feed on the plant's sap, causing leaves to turn yellow and die. They can be managed by using insecticidal soap or neem oil.
- Cutworms: These are caterpillars that feed on the plant's stem, causing wilting and death. They can be managed by using insecticides or by handpicking.
Effective management of these pests and diseases involves using a combination of cultural, mechanical, and chemical control practices. Cultural practices such as crop rotation, planting disease-resistant varieties, and practicing good sanitation can help to prevent diseases. Mechanical practices such as handpicking pests and infected plant parts can also be effective.
