General Information:
Sweet peas (Lathyrus odoratus) are annual climbing plants that are highly valued for their vibrant colours and delightful fragrance. With the right care and attention, you can enjoy a bountiful display of these charming blooms throughout the summer months.
Here are the key steps to grow sweet pea:
1. Choosing the Right Location
Sweet peas thrive in full sun or partial shade. Select a location in your garden that receives at least 6 hours of direct sunlight each day. Ensure the soil is well-draining and rich in organic matter.
2. Preparing the Soil
Before planting, prepare the soil by removing any weeds and loosening it with a garden fork. Incorporate compost or well-rotted manure to improve soil fertility and drainage.
3. Planting Sweet Pea Seeds
Sow sweet pea seeds directly into the ground in early spring or late autumn. Make a trench about 2 inches deep and space the seeds 2 inches apart. Cover the seeds with soil and water gently. It is a good idea to soak the pea seeds in warm water for a few hours before seeding to hasten germination. To have blooms more quickly use already started plants.
4. Providing Support
As sweet peas are climbing plants, they require support to grow vertically. Install trellises, stakes, or a wire mesh for the plants to climb on. This will prevent them from sprawling on the ground and promote better air circulation.
5. Watering and Feeding
Keep the soil consistently moist but not waterlogged. Water the plants at the base to avoid wetting the foliage, as this can lead to fungal diseases. Apply a balanced liquid fertilizer every two weeks to promote healthy growth and abundant flowering.
6. Pruning and Deadheading
Regularly remove faded flowers (deadheading) to encourage continuous blooming. Pinch out the tips of the plants when they reach about 6 inches in height to promote bushier growth and more flower production.
7. Pest and Disease Control
Monitor your sweet pea plants for common pests such as aphids and slugs. Use organic pest control methods to keep them at bay. Proper spacing and good airflow can help prevent fungal diseases like powdery mildew.
8. Harvesting Sweet Pea Blooms
Once the sweet pea flowers are in full bloom, you can start harvesting them. Cut the stems early in the morning when the stems are at their freshest. Enjoy their enchanting fragrance and use them in floral arrangements or simply display them in a vase.
