Frequently Asked Questions (FAQs)
1. What month do you plant sweet pea seeds?
You can plant sweet peas from October to March. Sweet peas are hardy annuals so planting them in October or November will give them a head start and a chance to establish really strong root growth before being planted out in spring.
2. How do I grow sweet peas from seed?
Use a good quality compost and sow several sweet pea seeds to a pot. Plant them about 1cm deep, cover with compost and water them well. Sweet peas perform best if their roots are forced to grow in a deep, narrow channel so choose a tall pot to give them a strong start.
3. How long do sweet pea seeds take to flower?
Spring-sown sweet peas flower in 12-14 weeks. Sweet peas often have a hard seed coat making them more difficult to germinate. To soften the seed coat, place your seeds on a layer of moist vermiculite or kitchen tissue in an airtight container in a warm room, and sow them as soon as they swell or begin to sprout.
4. Do sweet pea flowers produce seeds?
In addition to offering a rainbow of hues and an alluring fragrance, sweet peas also generously self-seed, so if you're looking to expand your existing patch, just let your plants go to seed, and you'll be set.
