Sweet peas can be trained to grow up a wall by providing them with a suitable support system and proper care. The video mentions "Grow a wall of sweet peas for your garden! #flowergarden," implying the possibility and desirability of this method. To achieve this, follow these steps:
1. Choose the Right Sweet Pea Variety
- Select climbing varieties of sweet peas, as bush types will not climb. Check the seed packet for information on the plant's growth habit.
2. Prepare the Wall and Soil
- Sunlight: Ensure the wall receives at least 6 hours of sunlight per day.
- Soil: Sweet peas prefer well-drained, fertile soil. Amend the soil near the wall with compost or well-rotted manure before planting.
3. Install a Support System
- This is crucial for training sweet peas to grow vertically. Options include:
- Trellis: Attach a trellis directly to the wall.
- Netting: Secure netting to the wall using hooks or staples.
- Wire or String: Create a grid pattern using strong wire or string anchored to the wall.
- DIY Frames: Build a custom frame to support the plants.
4. Plant the Sweet Peas
- Timing: Sow sweet pea seeds directly into the ground in early spring (or fall in milder climates). You can also start them indoors a few weeks before the last frost.
- Spacing: Space the seeds or seedlings about 6-8 inches apart along the base of the wall.
- Planting Depth: Plant seeds about 1 inch deep.
- Watering: Water gently after planting.
5. Train the Sweet Peas
- As the sweet peas grow, gently guide their tendrils towards the support structure.
- Use plant ties or twine to secure the stems to the support if needed. Sweet peas climb by clinging with their tendrils, so they need something to grab onto.
6. Ongoing Care
- Watering: Water regularly, especially during dry periods. Aim for consistent moisture but avoid waterlogging.
- Fertilizing: Feed sweet peas with a balanced fertilizer every few weeks during the growing season.
- Deadheading: Regularly remove faded flowers (deadheading) to encourage more blooms. As noted in the video transcription, "So that they don't go to seed. And make the plants stop blooming."
- Pest Control: Monitor for pests such as aphids or slugs and take appropriate action.
7. Enjoy Your Wall of Sweet Peas
- With proper care, you can enjoy a beautiful and fragrant wall of sweet peas throughout the growing season.
By following these steps, you can create a stunning vertical display of sweet peas on your wall. Remember to choose a sunny location, provide a strong support system, and consistently care for your plants.
