Growing Instructions
Sowing Petunia F1 Shake Cherryberry Seeds:
- When to Sow: Start seeds indoors from February to late April.
- How to Sow: These seeds are supplied as professional pellets (coated in inert clay) to make them easier to handle. Place the pellets on the surface of moist, well-drained seed compost. Do not cover them, as Petunia F1 Shake Cherryberry seeds need light for successful germination.
- The Dissolve Step: Mist the pellets thoroughly with a spray bottle until the clay coating begins to break down. If the pellet remains intact, the seed cannot access the moisture required to grow.
- Germination Conditions: Maintain a temperature between 20-27°C; seeds should germinate within 10–21 days.
Transplanting and Growing:
- After Germination: Once large enough to handle, transplant seedlings into 3-inch pots, placing them in a frost-free, well-lit location.
- Final Planting: Once the risk of frost has passed in late May, acclimatise them to outdoor conditions for a week before planting in containers, beds, or hanging baskets.
Care and Maintenance
- Watering: Keep the soil moist but not waterlogged. While this variety can tolerate brief dry periods, consistent moisture ensures the most prolific flowering.
- Fertilising: Use a balanced liquid fertiliser every two weeks once the first buds appear to maintain the heavy bloom production.
- Deadheading: Regularly remove spent blooms to encourage the plant to produce fresh flowers. Petunia F1 Shake Cherryberry is genetically compact and doesn’t require “pinching” to stay bushy.
Common Pests and Diseases
- Pests: Be mindful of aphids and slugs, especially when the plants are young.
- Diseases: Prevent powdery mildew and root rot by ensuring good air circulation and avoiding overly wet conditions.
