How to Propagate Periwinkle
Periwinkle can be grown from seeds or stem cuttings.
1. Growing Periwinkle from Seeds
- Sow seeds during spring or early summer.
- Use seed trays or small pots.
- Sow seeds ½ inch deep in moist soil.
- Germination occurs within 7–10 days.
- Transplant seedlings when they have 3–4 true leaves.
2. Growing from Stem Cuttings
- Take a 4–5 inch healthy stem cutting.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist soil.
- Roots develop within 2–3 weeks.
Cuttings produce flowers faster than seeds.
Planting Process
Follow these steps for healthy plant growth:
- Choose a sunny location.
- Prepare well-drained soil.
- Maintain spacing of 12–15 inches between plants.
- Water lightly after planting.
If planting in pots, use a 6–8 inch pot for one plant. Ensure proper drainage holes.
Watering Schedule
Periwinkle is drought-tolerant and does not require frequent watering.
- Water 2–3 times per week in summer.
- Reduce watering during monsoon.
- Allow soil to dry slightly between watering.
Important: Overwatering is the most common mistake. It may cause yellowing leaves and fungal diseases.
Fertilizer Management
Periwinkle does not need heavy feeding.
Recommended Fertilizer Plan:
- Apply compost once every 30–40 days.
- Use balanced NPK (10:10:10) fertilizer once in 45 days for better blooms.
- Foliar spray of micronutrients once a month improves flowering.
Excess nitrogen reduces flower production, so avoid heavy nitrogen fertilizers.
Pruning and Maintenance
Regular pruning encourages bushier growth and more flowers.
- Pinch young plants to promote branching.
- Remove dried flowers regularly.
- Trim leggy stems to maintain shape.
Pruning helps continuous blooming.
Pest and Disease Management
Periwinkle is relatively pest-resistant, but occasionally you may see:
- Aphids
- Spider mites
- Mealybugs
Control Measures:
- Spray neem oil every 15 days.
- Use mild soap solution for aphids.
- Ensure good air circulation.
Avoid water stagnation to prevent fungal infections.
