Can sweet peas be grown in pots?
Although sweet peas can be grown in pots or hanging baskets, a larger in-ground growing area is typically preferable. These plants want lots of space both in breadth and depth because the size of the blossoms is inversely proportional to the size of the roots.
It is advised to use containers that are at least 18 inches deep because lesser sizes can stunt growth. Use smaller containers if you don’t care about this. In either case, the blossoms are lovely. Just make sure to water them regularly to prevent drying out.
Look for sweet pea seeds that are advertised as being suitable for container growth.
In a warmer climate, yes. It is definitely feasible for some sweet pea plants to self-seed the next year if you allow them to go to seed in the fall and let the seed pods burst open and release the seeds. This is known to occur in zones 7 or warmer. If the seed does not freeze throughout the winter, it might also occur in regions with lower temperatures.
With pinching back (selectively removing the tips of major stems) and deadheading (removing dead blooms and their stalks), sweet peas will grow more profusely, although it’s completely optional.
At the time of planting, install the trellis or arch. Make sure the plants are getting hold of the supports and nicely covering the trellis by checking on them every few days.
Yes. Pods will develop once the blooms have finished blooming. These pods will contain seedlings. When they are brown and dried and the pods are just beginning to open, they are suitable for harvesting.
Yes. The secret is to select sweet peas when the blossoms at the stem’s top are still closed. Make a precise incision through the stem. Put the freshly cut flower right into a vase filled with room temperature water and cut flower preserver. In a vase, they typically last for 4 to 5 days.
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.
Do sweet peas have several blooms?
Pods that are close to the ground have black patches and cottony mold, and they are slimy rather than leathery or dry, making them unusable.
assemble the damaged pods and compost them. In the event that dry weather returns in time, healthy plants can yield a second crop. To avoid this, make sure plants get enough of sun and airflow so they can dry up fast after rain. Apply mulch. Water at soil level rather than from above.
spring
- From March to May, you can easily plant your young sweet pea plants outside. Before planting out, sweet pea seeds sown in the winter or autumn need to be potted up into larger containers. Spring-sown seeds can be transplanted from their rootrainers.
summer
- Pick your sweet peas, then put them in indoor vases. Remove the seed pods from your sweet peas to continue deadheading them. You’ll need to harvest and deadhead them frequently when they’re at their height.
How can I harvest sweet pea seeds?
To tie in sweet peas, view David Hurrion’s No Fuss video tutorial here:
When blossoms start to develop, start fertilizing with a heavy potash fertilizer, such tomato food. Picking regularly will promote more blooms and stop plants from setting seed. In extremely dry conditions and when growing in pots, water sweet peas.
Learn how to extend your sweet pea crops in this useful video from Monty Don. Monty explains how routine picking will keep your plants in bloom well into September and throughout the summer. Additionally, you’ll always have fresh flowers for the home:
Growing sweet peas: problem solving
Slug and snail damage is more common in young sweet pea plants. Use copper bands, beer traps, or the biological control Nemaslug to keep them away. Learn more about repelling snails and slugs.
Leggy sweet peas can occur occasionally. David Hurrion offers the following advice on how to save them:
The soil around plants can become particularly dry in hot, bright weather, which can cause sweet peas to lose their blossoms. Check out this Quick Tips video with Catherine Mansley from BBC Gardeners’ World Magazine for tips on how to handle and avoid this issue:
Saving sweet pea seeds
Starting in early September, seed can be harvested. Till they have taken on the color of a paper bag, leave the seed pods on the plants. When you’re ready to sow them, gather them on a dry day, separate them from their pods, and store them in paper bags in a dry location.
What are some wintertime uses for sweet peas?
Sweet peas can endure nighttime lows of about -5, but they do not enjoy being kept in frozen pots all day. In the event that you go overboard and kill the top growth, there’s a good chance that if you give them some warmth, they’ll have developed enough roots to sprout anew.
Sweet peas do they last all summer?
The beginning of longer days stimulates the blooming season of the majority of sweet pea flower kinds. The optimum time to sow your sweet pea plants is after the winter solstice when the days are becoming longer and they will be ready for blossoming in the spring.
Sweet peas are not adversely affected by a light frost in USDA plant hardiness zones 8 through 10. Sweet peas blossom during the duration of the moderate weather as long as they have some protection from the hot western sunlight in the late afternoon. Your sweet peas will respond by slowing blossom growth if summer temperatures start to arrive in the spring.
Do peas keep on producing?
Wherever a chilly spring quickly transitions to a hot summer, as it happens in much of Minnesota, the pea growing season is brief. Areas close to Lake Superior and in the state’s far north may experience milder summer temperatures and have more time to grow peas.
Before being harvested, the majority of pea cultivars require 60 days of development. However, as temperatures get beyond 85°F, as they frequently do in June, they will stop developing and cease to produce blooms or pods.
Despite the fact that the plants do require full sun, peas that are grown in hot weather may also be of low quality. It’s crucial to begin planting as soon as possible. It might be a good idea to prepare the planting space in the preceding fall.
Here are some recommendations for planting peas:
- As soon as the soil has defrosted and is usable, plant the seed.
- At the foot of the trellis, grow tall, vining variety in a single row. Trellises can have two vertical stakes connected by netting or rope.
- Close to a trellis, shorter shrub varieties can be planted in a single row. The plants will cling to and support one another if you plant them in a wide row that is between 12 and 18 inches wide.
- Be gentle with the pea seed. Cracked seeds are less likely to germinate, particularly in the early spring’s chilly, damp soil.
- Six to seven inches apart, spread the seeds out in a shallow trench. Spread the seed out over the prepared seedbed in a wide row, spacing the seeds about two inches apart in all directions.
- Put the seeds evenly into a small soil trench. Make sure they are evenly spaced apart, then add one inch of dirt to cover them.
- Over the seeds, compact the dirt. For a longer harvest period, you might plant again a week later and again a week after that.
Pea plants in their infancy can withstand brief light frosts and will thrive in any temperature above 40°F. The range of 55 to 65 degrees Fahrenheit is ideal for growing. Frost can be harmful to plants once they have begun to blossom and produce a yield. Keep an eye out for any predictions of a late spring frost and, if required, cover the plants with sheets or row covers.
Are peas a perennial or annual crop?
The majority of legumes produced in backyard gardens, such as beans and peas, are annual plants, meaning they go through their entire life cycle in a single year. On the other side, perennial legumes are ones that can survive for more than two years.
How to sow sweet pea seeds
Sweet pea flower seeds are frequently advised to be nicked or chipped before planting, as well as to soak in water or damp paper towels for the night, although none of these steps are necessary. Sweet peas thrive in root trainers, which are unique tall plug trays, or 9cm pots since they prefer to have a long root run. But a toilet paper roll’s cardboard interior will also work.
Individual seeds can be sown in toilet paper inners or root trainers, or two to three seeds can be planted in a 9 cm pot. The container should be filled with seed compost, dampened, and then the seed should be pushed in with your finger to a depth of about 1 cm. Add some compost to the top and gradually water. Put the pots in a protected area that is well-lit. Unlike other seeds, they do not require additional heat from a propagator. When the seedlings emerge, place the pots somewhere sunny and cold, ideally between 5 and 10 degrees Celsius, or else they will grow long and lanky.
What month do you plant sweet peas?
Sweet peas can be purchased as plug plants or are produced from seed. If starting from seeds, you can plant them in the spring (February to April) or the autumn (usually October or November), and then nurture the seedlings into little plants.
Autumn and early spring seeds require a frost-free environment to thrive, such as a cold greenhouse or cold frame. It is better to wait and plant the seed later, in April, when you can start them off easily on a windowsill inside, if you don’t have a place that is cool and light like this. Alternately, in late April and early May, direct-sow outdoors in larger pots or the ground.

How to grow and care for sweet pea flowers
When your sweet pea seedlings are about 10 cm tall after spring sowing, you can pinch out the tips to help them develop into vigorous, bushy plants with lots of flowering side shoots. Just above a pair of leaves, place the growing point at the top of the stem between your finger and thumb, squeeze it, and snip it off. Avoid pinching the tips of plants seeded in the fall.
Prepare your seedlings and plugs for growing outdoors by hardening them off after there is no possibility of frost, often starting in late May. To help them get acclimated to the cooler weather, this entails leaving them outside during the day and bringing them inside at night for about a week.
Their final growing location should be in a sunny, open area with fertile soil that has good drainage. Because they climb, annual sweet peas require a support to develop. trellis, netting, a cane teepee, a border obelisk, or a garden arch are typical examples. Plant the sweet peas 15-20 cm apart, 5 cm from the base of the support you’ve chosen.
If grown in pots, plant the compost with some slow-release fertilizer to keep the plants healthy all season. Keep the plants well-watered and keep an eye out for slug and snail damage.
Sweet pea blossoms should be secured to their support as they enlarge using garden twine or support rings. Once the sweet pea blooms begin to bloom, routinely treat them with tomato fertilizer. Continue picking flowers throughout the summer because the more you pick, the more are generated.
Do sweet peas come back every year?
Sweet pea blooms come in annual and perennial varieties. Lathyrus odoratus, an annual plant that must be sown from seed every year, is typically a climber with a strong fragrance. Every spring, the perennial or “everlasting” varieties of Lathyrus latifolius reappear, however the majority of them have little or no perfume. Some don’t climb; they are bushy.
Do sweet pea pods need to be removed?
You must consistently water your flowers throughout the growing season since dry soil causes them to set seed more quickly. When your sweet pea plants are fully bloomed, be sure to deadhead them and remove seed pods as soon as you can to promote the production of new blooms.
