Propagation of Oldenlandia corymbosa L. var. linearis (DC.) Verdc.
Oldenlandia corymbosa L. var. linearis (DC.) Verdc. is a herbaceous plant that belongs to the family Rubiaceae. It is a perennial plant that can be propagated through various methods such as seeds, stem cuttings, and division.
Propagation through seeds
The propagation of Oldenlandia corymbosa L. var. linearis (DC.) Verdc. through seeds can be done in early spring or autumn. The seeds should be sown in well-draining soil with a pH of 5.0 to 6.5. They should be lightly covered with soil and watered regularly. The seeds will germinate in 7 to 14 days.
Propagation through stem cuttings
Propagation through stem cuttings is an effective way to reproduce Oldenlandia corymbosa L. var. linearis (DC.) Verdc. Select a healthy stem with at least two to three pairs of leaves. Cut the stem just below a node and remove the lower leaves. Dip the cut end of the stem into rooting hormone powder and plant it in well-draining soil.

This method involves dividing a mature plant into smaller sections and replanting them in separate containers. Dig up the plant and carefully separate the roots into sections. Each section should have at least one healthy shoot and root system. Plant the separated sections in well-draining soil and water them regularly.
Overall, Oldenlandia corymbosa L. var. linearis (DC.) Verdc. can be propagated through various methods such as seeds, stem cuttings, and division. Each method has its own advantages and disadvantages, so it is important to choose the most appropriate method for your specific needs.
Disease Management
Oldenlandia corymbosa L. var. linearis (DC.) Verdc. plant is susceptible to various diseases, including powdery mildew, anthracnose, leaf spot, and rust. Here are some ways to manage these diseases:
- Powdery mildew: Avoid overhead watering to prevent the infection from spreading. Use a fungicide with active ingredients like potassium bicarbonate, sulfur, or neem oil to control the disease.
- Anthracnose: Keep the plant foliage dry to stop the spread of the cane disease. Pseudomonas fluorescens and Bacillus subtilis are biological fungicides that can help control anthracnose in Oldenlandia corymbosa L. var. linearis (DC.) Verdc.
- Leaf spot: Remove infected leaves and dispose of them to prevent the spread of spores. Use a copper-based fungicide to control the disease.
- Rust: Inspect the plant regularly and remove any infected leaves. Fungicides containing tebuconazole or azoxystrobin can help reduce the disease's severity.
