Sweet peas are available in a wide variety of hues and designs. The majority will only reach a height of 5 or 6 feet, while shorter “bush type” variants are ideal for containers. Pick a few different varieties to extend the flowering season. Find types that bloom early (“short-day”) and late by reading the seed packs (“long day). Even though annual sweet peas predominate, perennial sweet peas are also available (Lathyrus latifolia).
Start early
It’s crucial to start sweet peas (Lathyrus odoratus) blossoming early so they can survive the summer heat because they like chilly temperatures. As soon as the soil can be handled in the spring, you can plant them outside. The seeds will likely be alright even though it will likely still be very chilly. Sweet peas can be planted in the south in late fall for late winter or early spring blossom. Consult local cooperative extension to learn about best practices in your community.
Start your peas inside for the longest blooming season possible. Timing is determined by the date of your region’s last frost. Back up the date by four to six weeks once you get it. You should then plant. For instance, you should plant in early to mid-April if your last frost date is May 15. Don’t know when your region last experienced frost? Consult local cooperative extension or a reliable gardener in the area.
How much room are sweet pea plants required for?
After scarifying your sweet pea seeds, Myers advises planting them outdoors in a location that receives at least six hours of direct sunlight each day for the best blossoming. If you live in a hotter region, she suggests providing some afternoon shade to lengthen the blooming period. In order to give sweet pea seeds enough room to grow, Godfrey advises sowing them about one inch deep and three to four inches apart. He continues, “Plant in rich, draining soil. If the soil is excessively moist or dry, sweet peas won’t thrive.
Are sweet peas trellis-required?
One of the best plants for cutting, sweet peas (officially known as Lathyrus odoratus) offer tempting colors and aroma for spring and early summer bouquets. The tiny flowers emit a grape-like fragrance into the air and come in a variety of beautiful colors. We enlisted the assistance of Barb Pierson, our nursery manager, to provide some guidance for individuals who have never grown Sweet Peas in a garden or a container pot. Any beginner or green thumb can benefit from a plentiful supply of these lovely flowers thanks to her advice.
Why do people grow Sweet Peas?
Sweet peas are cultivated for their lovely, ruffled blossoms, which come in pastel, blue, and bicolor hues. They are a beautiful cut flower since many types have scented blooms. The cultivation and breeding of sweet peas for both the home grower and the florist industry has a long history.
How do I go about growing Sweet Peas?
Sweet peas can be grown from seed that is treated before sowing or, more conveniently, from a starting plant. At White Flower Farm, we plant three seeds in each pot to create three Sweet Pea vines.
Where do I plant them and when?
In the northern half of the US, sweet peas flourish in the full sun. They can benefit from afternoon shade in the South. They are planted as early as possible in the spring since they prefer mild temperatures and cool roots. Newly planted seedlings will not be harmed by a mild cold. They can be sown in the fall and cultivated through the winter and early spring in highly warm climates. Compost should be added to the soil, and the area should be well-drained for optimal results. Sweet peas can be successfully grown in raised beds.
Do they need any special care while they are growing?
Sweet peas require support to grow and flower because they are climbing plants. Many other kinds of structures, like a trellis, supports made of mesh or wire, or fences, can be used. To sustain the weight of the vines, they require a sturdy framework that is firmly planted in the ground. The vegetation will develop tendrils that encircle the support you offer.
Since they like nutrient-rich soil, adding compost at planting time is advised. Mulching Sweet Peas will keep the roots cool and help them retain moisture as they grow.
Pinch the growth tips by one after the plants have reached a height of around six to encourage branching and the development of extra flowering stems.
What are the most common mistakes that people make with Sweet Peas?
- planting them in the middle of the summer They dislike the heat and won’t blossom as frequently.
- not offering assistance when planting. Once the plants have begun to grow, it is challenging to install your trellis or support.
- Lack of compost or fertilizer will cause weak plants and fewer flowers in poor soil.
- If Sweet Peas are planted too closely together without being thinned out, powdery mildew can grow and crowding lowers bloom production.
Do Sweet Peas produce pods that you can eat like the ones you find in the grocery store?
Despite having the appearance of snap pea pods, the seed pods are not edible. The pods and seeds can be saved in order to grow plants the following year. Remember that the plants that the seeds may grow may not be the same hue as the parent plant.
Will the plants come back again next year?
The plants are typically not winter hardy in most areas. They are replanted with new seed and plants even in warm climates to produce the most flowers and have robust development.
When do they bloom? Are there tips for getting extra blossoms?
Sweet peas will begin to blossom 4 to 6 weeks after they begin to show apparent vining. Whether or not the plants have been pulled back will affect the timing of the bloom. Although pinching may slightly limit growth, it will result in bushier plants with more flowers. In the spring and early summer, sweet peas will grow and bloom more quickly as the days lengthen. Compost or old dry manure can aid to supply nutrients for the growth of huge, many blooms. A fertilizer with a phosphorus to nitrogen ratio greater than one can also increase flower production.
What is the process for cutting the blooms?
Cut the blossoms early in the day to prevent the sun from drying them off. For your vase, select newly opened flowers with the longest stems. Just the side flowering stems of the plant should be clipped; leave the main stem alone.

Do sweet peas return each year?
Although Lathyrus odoratus, the most popular sweet pea variety, is an annual, there are also perennial forms available (Lathyrus latifolius).
- 1. Annual sweet peas are plants that go through their entire life cycle in a single growing season. They grow, produce seeds, and perish within the span of a year, just like other annual crops. The next year, you must replant new plants in your garden if you want to grow them again. The majority of sweet pea species are annuals.
- 2. Perennial sweet peas: These flowers reappear each year. After the growth season is over, you don’t need to replant them because they will keep growing for a longer period of time. Although there are fewer types of perennial sweet peas available and they tend to lack the traditional sweet pea aroma, they may be simpler to grow.
Sweet peas grow great in containers, right?
Sweet peas can be grown in pots with great success as long as a few simple guidelines are followed. which are

- Keep well-hydrated. Every day that it does not rain, make sure there is good drainage from the container and water. When plants develop
When fully grown, watering could be required even when it’s raining because the foliage diverts the water from the container.
Make sure the soil is nutrient-rich and has high moisture-retention abilities.

Can a hanging basket be used to cultivate sweet peas?
Information on Care. Patio sweet peas produce a beautiful and eye-catching show when planted alone in hanging baskets and containers. They can also be cultivated with other plants, where they will wind their way up stems to produce amazing effects.
Slugs eat sweet peas, right?
Slugs frequently destroy tulips, hostas, delphiniums, dahlias, gerberas, and sweet peas, making it challenging to grow these flowers if you have a significant slug problem. Peas, beans, lettuce, celery, and potato tubers are frequently harmed in the vegetable garden.
Are sweet peas sun-loving plants?
Before putting sweet pea seedlings in the garden, you should harden them off. As a result, the plants can adjust to the chilly outside air. Place the pots outside throughout the day for one to two weeks before bringing them inside at night.
After your region’s final date of frost, make sure to plant the sweet peas outside. A location with rich, well-drained soil and full sun or very little dappled shadow is ideal. In the weeks leading up to planting the seedlings outside, add a lot of organic matter.
Water in after spacing the seedlings around 20 cm apart. Water the plants frequently, particularly during dry seasons.
How are sweet peas trellised?
- Sweet peas can be seeded in the fall in warmer places (Zone 7 and above) where the winters are generally not too harsh. Other than that, plant seeds in late winter or early spring. Before planting, give the seeds a 24-hour soak in water. By doing so, the seed coat is softer and the sprouting process is accelerated.
- Fill your planting containers with high-quality potting soil while the seeds are soaking. Use the deepest pots you can find because sweet peas develop a lot of roots. Ideal containers are 4-inch (10-cm) pots and root trainers.
- In each container, plant two seeds by pressing a fingertip into the soil and a half-inch (1.25 cm) deep.
- To boost humidity and hasten germination, cover pots with a plastic dome covering. Place in a warm greenhouse or a house window with good light.
- Pinch out the center growth tip, just above a leaf joint, once plants are 4 to 6 inches (10 to 15 cm) tall, leaving just two or three leaf nodes. The plant will be encouraged to branch out strongly from the base as a result.
- Because they use a lot of food, sweet peas need a little more care to produce in large quantities. Apply bone meal, a thick layer of compost or well-rotted manure, and a generous amount of natural fertilizer to planting beds to prepare them. Incorporate these elements thoroughly into the soil.
- Vines require a sturdy foundation to climb and grow quickly. Affix Hortonova netting or 6-foot (1.8 m) tall metal fence to the tall poles spaced approximately 8 feet (2.4 m) apart down the row for them to climb.
- Around the time of the final spring frost, plant seedlings outdoors in two rows, one on either side of the trellis, spaced approximately 8 inches (20 cm) apart down the row. It’s crucial to keep the vines bound to their supports as they erupt into lush growth. Sweet peas can grow more than a foot (30.5 cm) per week once the vines begin going.
- Sweet peas adore water, and they can’t survive without regular watering. Set up soaker hoses as soon as you plant them to prevent their luxuriant development from being restrained. It’s important to maintain their thirst quenched during warm weather. Use diluted fish and seaweed emulsion to feed plants once a week.
- Pick flowers when there are at least two unopened blooms remaining on the stem for the greatest vase life. To extend the life of the vase, add flower food to the water. It’s crucial to prevent plants from going to seed in order to prolong blooming, so be sure to regularly harvest and deadhead the flowers.
