A. Seed Propagation
- Harvesting Seeds: Once the Candytuft flowers fade and seed pods form, let them dry on the plant. Then, collect the pods and extract the seeds.
- Seed Preparation: No pretreatment is generally required for Candytuft seeds.
- Sowing: Fill a seed tray or pots with a well-draining potting mix. Sprinkle the seeds over the surface and cover lightly with soil. Moisten the top layer.
- Germination: Place the seed tray in a sunny location. Keep the soil moist, but not soggy. Seeds should germinate in 1-2 weeks.
- Transplanting: Once seedlings have at least two sets of true leaves and are robust enough to handle, transplant them to their final location or individual pots.
- Take Cuttings: In late summer, select healthy, non-flowering shoots. Using sterilized shears, cut a 3-4 inch section from the tip of the shoot.
- Prepare the Cutting: Remove the lower leaves, leaving only a couple at the top. Dip the cut end into rooting hormone.
- Planting: Insert the cuttings into pots filled with moist potting mix.
- Maintaining Humidity: Cover the pot with a clear plastic bag or a plastic dome, creating a mini greenhouse effect. This retains moisture and aids root development.
- Root Development: Place the pots in indirect light. Roots typically develop in a few weeks. Once rooted, cuttings can be transplanted to their final location.
- Watering: Whether grown from seed or cuttings, young Candytuft plants require consistent moisture. However, avoid waterlogged conditions which can lead to root rot.
- Light: Place them in a location with full sun or partial shade.
- Feeding: Once established, Candytuft benefits from a balanced, slow-release fertilizer in the spring.
- Pruning: Post-flowering, give the plants a light trim to maintain shape and encourage denser growth.
- Pests: Watch out for aphids and caterpillars. Treat any infestations promptly with organic insecticidal soap or neem oil.
- Diseases: Candytuft can occasionally suffer from root rot if conditions are too wet. Ensure proper drainage to prevent this issue.
