Why Choose Sweet Peas?

Sweet peas (Lathyrus odoratus) are not just flowers; they're an embodiment of charm and elegance. With their delightful fragrance and a wide array of colors, they add a touch of whimsy to any garden. Growing them from seed allows you to select from a myriad of varieties, ensuring your garden is a canvas of personalised beauty.

Sowing Sweet Pea Seeds

  1. Choose sweet pea varieties that suit your taste and garden aesthetics. Some popular choices include 'Spencer Mix,' 'Old Spice Mix,' and 'Cupani.'

  2. Sweet peas prefer well-draining soil with added organic matter. Prepare the soil by mixing in compost for a nutrient-rich foundation.

  3. In the UK, the ideal time to sow sweet pea seeds is in late autumn or early spring. If starting indoors, begin sowing in pots or seed trays around October to November. For outdoor sowings, wait until March or April.

  4. To enhance germination, consider scarifying the seeds by nicking the outer seed coat with a file or sandpaper. Soak the seeds in water overnight before planting.

  5. Plant seeds at a depth of about 1 inch (2.5 cm) and provide support for the growing vines. Sweet peas are climbers and appreciate structures like trellises or bamboo canes.

Caring for Sweet Peas

Keep the soil consistently moist, especially during dry spells. Avoid waterlogged conditions, as sweet peas prefer well-draining soil.

Sweet peas thrive in full sun to partial shade. Ensure they receive at least 6 hours of sunlight daily for optimal growth and bloom.

Provide a balanced liquid fertilizer every 2-3 weeks to support robust growth and vibrant blooms.

Remove spent flowers regularly to encourage continuous blooming throughout the season.

Harvesting and Enjoying Sweet Peas

As your sweet peas begin to bloom, revel in their fragrance and charm. Harvest flowers regularly to promote further flowering. Sweet peas are perfect for creating stunning bouquets, bringing the essence of your garden indoors.

Growing sweet peas from seed is a journey of cultivating elegance and capturing the essence of nature's beauty. Sow the seeds and watchyour sweet peas bloom into a spectacle of colour and fragrance. Unleash the magic in your garden and let the sweet pea symphony begin!
