Propagation of Boerhavia diffusa L. var. viscosa (Lag. & Rodr.) Heimerl
Boerhavia diffusa L. var. viscosa (Lag. & Rodr.) Heimerl or commonly known as "Punarnava" is a perennial herb that belongs to the Nyctaginaceae family. This plant is native to tropical and subtropical regions worldwide and has been used for various medicinal purposes.
Propagation Methods
Boerhavia diffusa L. var. viscosa (Lag. & Rodr.) Heimerl can be propagated through both sexual and asexual methods.
Seed Propagation
Seeds of Boerhavia diffusa L. var. viscosa (Lag. & Rodr.) Heimerl can be sown directly in the farm or nursery beds. They can be planted during early spring or late fall when the temperature is moderate, and the moisture level is high. Seeds should be sown at a depth of about 1 cm and spaced at least 10 cm apart. Germination usually takes 5 to 7 days, and the seedlings can be transplanted to the field or individual pots when they have developed 3 to 4 true leaves.
Vegetative Propagation
Boerhavia diffusa L. var. viscosa (Lag. & Rodr.) Heimerl can also be propagated through vegetative means such as stem cuttings, root cuttings, and division.
- Stem Cuttings: Select healthy stems at least 10 cm long and remove the bottom leaves. The cuttings should be dipped in rooting hormone and planted in a well-draining potting mix. Water the cutting thoroughly and keep the soil moist until the roots have developed.
- Root Cuttings: This method involves taking root cuttings from the mother plant, usually during the dormant season. Cut the roots into sections, and each section should have at least one bud. Plant the cuttings in a potting mix and keep the soil moist until the new plant develops roots.
- Division: This method involves dividing the mother plant into multiple parts and replanting each part. The ideal time for division is during early spring or late fall when the plant is dormant. Dig up the clump and separate the root ball into sections, ensuring that each section has sufficient roots and shoots. Plant the sections in a well-draining potting mix and keep the soil moist until the new plant develops roots.
With proper care and maintenance, Boerhavia diffusa L. var. viscosa (Lag. & Rodr.) Heimerl propagates quickly and can reach maturity within a year.

Proper disease and pest management can help in maintaining the health of the sticky spiderling plant.
Common Diseases Affecting Boerhavia Diffusa L. Var. Viscosa
Some of the common diseases that affect the sticky spiderling plant include leaf spot, powdery mildew, root rot, and bacterial blight.
Leaf Spot
Leaf spot is a type of fungal infection that affects the leaves of the plant. It generally appears as circular brown or black spots on the leaves. It can be managed by reducing the amount of water given to the plant and trimming the infected leaves. Fungicides can also be used to reduce the spread of the disease.
Powdery Mildew
Powdery mildew is a fungal infection that appears as white powder-like spots on the leaves of the plant. It can be controlled by ensuring adequate ventilation around the plant and avoiding overhead watering. Fungicides can also be used to treat the disease.
Root Rot
Root rot is a fungal infection that affects the roots of the plant. It occurs due to overwatering or poorly draining soil. To prevent root rot, the plant should be watered moderately, and the soil should be well-draining. Trimming off the infected roots is also recommended.
Bacterial Blight
Bacterial blight is a bacterial infection that primarily affects the leaves of the plant. It appears as water-soaked lesions on the leaves, which eventually turn brown and dry. Infected plants should be removed immediately to prevent the spread of the disease to other plants.
Common Pests Affecting Boerhavia Diffusa L. Var. Viscosa
Some of the common pests that affect the sticky spiderling plant include spider mites, mealybugs, and aphids.
Spider Mites
Spider mites are tiny pests that suck out the sap from the leaves of the plant. They usually appear as small red or brown spots on the leaves. A simple way to control spider mites is by spraying the plant with water and ensuring adequate ventilation. In severe cases, insecticides can also be used.
Mealybugs
Mealybugs are soft-bodied insects that suck out the sap from the leaves and stems of the plant. They appear as white cotton-like clusters on the leaves. They can be removed manually by wiping them off with a damp cloth. Insecticidal soaps can also be used to control their spread.
Aphids
Aphids are small insects that generally appear on the underside of the leaves. They suck out the sap from the plant, which can result in stunted plant growth. A simple way to control aphids is by spraying the plant with water or insecticidal soap. In severe cases, insecticides can also be used.
Overall, proper care and attention can help in preventing diseases and pests from affecting the sticky spiderling plant. Early detection and prompt management can help in maintaining the health of the plant and ensuring that it grows optimally.
