Sweet Pea Culture
Prepare the ground in Autumn
Bernard Jones is the British author of the classic reference book, Sweet Peas, now hard to find except in libraries. Additional advice on growing Sweet Peas can be found in abundance on the web at: Fragrantgarden.com.
Knowing how to grow sweet peas is important for success with these fragrant beauties. They prefer long, cool springs and summers to grow enormous flowers and luxuriant 9' plants. Yes, they will grow, as Gladys says, if you just poke them into the soil and wait. However, the best results are obtained by preparing the soil well by mixing in compost and manure. Sweet peas require alkaline conditions, so sprinkle enough lime on the soil to give it a snow-dusted appearance. If you take the time to nick the hard shell of each pea opposite its eye, you'll greatly improve germination. You can also soak them for 24 hours before planting. This will enable them to absorb moisture and sprout quickly. Protect freshly sown seeds from mice and new sprouts from slugs. Once up and growing they like moisture - one inch a week, with a good soaking, is best.
Plant at OVF in August through October for early spring bloom, November to January for late spring bloom.
Experience has shown that although we have cool springs we do have unseasonable hot spells in March, so the earlier the better for sweet peas at OVF.
