How to grow sweet peas Sarah Raven?
Sarah’s sweet pea growing method I place my plants about six inches apart, with a trench of manure at their roots, then let them get on with it. Every couple of weeks, I tie the new growth in, but that’s it until I start picking. I pick away from the end of May until the end of July, dead-heading as I cut. Although sweet peas are self-clinging climbers, tying the main stems to the supports helps to get the plants growing in the right direction. Water regularly, especially during dry periods. Once the flowers appear, feed fortnightly with a high potash feed – tomato feed is ideal.Sweet peas should have direct sunlight for six to eight hours every day. The more light the plants have, the better they flower. And speaking of light, they prefer long days. The ideal day length is 16 hours, followed by eight hours of darkness.As the flowers open keep cutting; this stimulates further flower production. Never leave seeds to develop on the plants. Remember that sweet peas are annuals. If seeds develop they tell the plant that its work is done and the plant starts to die back.Cut the flowers every day or so. Sweet peas are one of the most generous flowers of summer. Cut them and you will get more and more flowers, leave them on the plant and they will inevitably form seed pods that you miss.
Do sweet peas grow back every year?
Sweet peas (Lathyrus odoratus) only live for a year, dying after setting seed. But don’t let this put you off as they are super easy to grow from seed. Perennial species such as Lathyrus latifolius come back year after year, but mostly lack fragrance and there are fewer to choose from. Start feeding sweet peas with a high potash fertiliser (such as tomato food) when flower buds appear. Regular picking encourages more flowers to form, so keep picking those blooms for the vase.Ideal timing: plant sweet peas outdoors when the soil is cool but workable, typically in march or april for most areas. For fall planting, aim for late september to allow plants to establish roots before frost.How do I encourage my Sweet Peas to produce more flowers? Rosebie recommends feeding each week using a granular fertiliser such as Vitax Q4. Even more important is to prevent your Sweet Peas from going to seed during the flowering season, so make sure you keep deadheading or picking the flowers.Once your sweet peas start blooming, do not let the flowers go to seed. Cut or deadhead them regularly to promote the production of more flowers and keep your plants looking their best. Toward the end of the growing season, you can leave some seedpods on the plant if you want to collect the seeds to sow next year.Sweet Peas will start blooming approximately 4 -6 weeks after visible vining. Timing of bloom will depend on whether the plants have been pinched back. Pinching may slow growth somewhat, but it will produce bushy plants with more flowers.
What is the secret to growing sweet peas?
Sweet peas love water, and without consistent moisture, they won’t thrive. Keeping their thirst quenched during warm weather is crucial, so set up drip irrigation or soaker hoses as soon as you plant them. We water deeply 2 to 3 times a week. Tie your sweet peas into their vertical frames so they don’t waste energy holding themselves upright. Water them well so they don’t become stressed in a drought. You can also pinch out all the curly stems and tendrils, allowing the energy to go into growing longer stems and flowers.Sweet peas are heavy feeders, so amend soil well before planting with lots of rich compost or well-rotted manure. During the growing season, fertilize at least twice with a good soil drench of tablespoon each of fish emulsion and liquid kelp per gallon of water.Sweet peas have big and long root systems with a big and long taproot that grows deep. This is a good thing as far as the plant goes (helps them to establish themselves quickly and readily, even makes the vines pretty drought tolerant) but it can cause some difficulty when you’re starting them from seed.If sowing in autumn ensure you have the room to grow them on in a frost-free place until spring. Sweet pea seeds germinate relatively easily. But you can help activate germination by nicking the seed coat with a knife, avoiding the ‘eye’ area. Either sow seed in 9cm pots (3 to a pot), in root trainers or trays.
What is the best month to plant sweet peas?
If you garden in mild winter climates (Zones 8, 9, or 10), plant sweet peas in the late fall (November) so they can develop and bloom in late winter and early spring.

Protect with double low tunnels or frost cloth to overwinter.Sweet peas are easy to grow in any fertile soil that drains easily, in full sun. Feed weekly or fortnightly with a liquid fertiliser and ensure a regular supply of flowers by picking or deadheading.Cut perennial Lathyrus back to ground level in autumn or, preferably, leave the cutting back until February so the dead stems provide cover for wildlife in winter. Simply pull out and compost annual sweet peas once flowering has finished at the end of summer.Leave healthy plants stand for winter to increase hardiness. Prune the plants back to the ground in late winter or early spring before growth begins. Prune sweet pea plants with diseased foliage back to the ground in fall.Feed your sweet pea plants with a general fertiliser every couple of weeks, or sprinkle on comfrey pellets. A potash-rich tomato feed is ideal. If you maintain a good watering and feeding regime, the sweet peas can go on into August.
