If stored properly, sweet pea seeds should be viable for two to three years.
Simply let the mature pods on the plant until they are ready to be picked, let them dry, and then store them to harvest sweet pea seeds.

In the garden, how long do sweet peas last?
To make those cut sweet pea flowers endure as long as possible in the vase, some management is required. Provide clean water every day to provide the flowers the minerals and moisture they need to be healthy.
Each stem can be periodically trimmed by 1/4 inch to encourage the flower to continue drinking water for a longer amount of time and prolong bloom time. Cut sweet peas can look stunning for up to a week if you take care of them.
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.
A pea plant’s lifespan is how long?
Harvesting frequently. To promote the growth of new pods and increase yield from peas over a potential bearing period of weeks to months, harvest pea pods on a regular basis, such as every day or every other day. Pea plants may only produce a few new pods while the seeds in their current pods mature.
Avoid letting any pods remain on pea plants by carefully inspecting the plants. The life cycle of pea plants is based on reproduction, just as all annual crops (blooming then setting seeds). The plant may stop producing, deteriorate, and die if pods are allowed to remain on the plant until the seeds are fully developed. If you pick all of the pods while they are still young, a pea plant may continue to produce reliably for two to three months or longer. However, if you wait for the first dozen or two pods to mature and generate seeds, it may exhaust the plant and become your entire harvest. A plant’s output may be decreased and the harvest period shortened if a few pods, such as those tucked down amid the weeks or in another out-of-sight location, are left unharvested.
Consume right away following harvest. As sugars in the pods and seeds change to starches, peas may quickly lose their flavor and sweetness at maturity, in hot conditions, and within hours to days of being picked. As soon as they are harvested, they are best used or kept. The flavor of peas can be badly impacted by even two or three days of extreme heat. The less palatable peas may need to be shelled in order to be consumed because older pods become more stringy, rough, and lacking in sweetness.
When the weather is warm, provide shade. At high temperatures, the production of pods may dramatically decrease or cease. On warm to hot days, provide shade to help peas to produce for an extended amount of time.
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.
Do sweet peas reproduce on their own?
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.
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.
Can sweet peas endure the winter?
According to Gardeners’ World (opens in new tab), sweet peas should be treated like any other non-hardy annual: “Plant your sweet peas outside starting in late May, after all danger of frost has passed. Put them outside throughout the day and bring them inside at night to harden them off before planting.
The most recent edition of Sarah Raven’s podcast (opens in new tab) claims, however, that “Sweet peas are hardy and can go in the garden from the middle of March.”
Confused? So were we up till we learned the RHS’s excellent sweetpea-growing tips (opens in new tab) (watch in the video above). Sweet peas are in fact “extremely tough,” says Propagation Leader Sam Gallivan, and they can withstand frosts “with no issue at all.” They do struggle with extended cold and rainy times, though. Your young sweet pea plants could perish if you reside in a region where early spring can bring both low temperatures just above freezing and a lot of rain.
Because of this, you have two options: either hold off and plant them outside in April when the weather will be warmer, even if it rains, or keep them in a cold frame until the chilly showers stop. However, sweet peas are typically categorized as half-hardy annuals and can withstand dry frost up to -4C. (25F). You will need to cover them with horticultural fleece in the event that temps fall below that.
Are sweet peas tough?
Sweet peas are a robust annual, so they can withstand cold temperatures, including a light frost if it is below freezing. They can withstand a regular cold down to about -4 degrees and are tougher than they appear. Sweet peas only need to be protected, such as with a fleece, if a heavy frost or extended period of low temperatures is predicted.
Do not wait until it is too late to grow sweet peas because they are hardy. Sweet peas can be sown beginning in March. The sweet peas grow best when tied to a structure, like a trellis or an obelisk.
Remove the tendrils and don’t allow them grow unchecked if you want straight stems and sweet peas that grow up the frame rather than a tangled clump. Why? See how to give sweet peas straight stems.
Don’t let the seed head form; keep plucking sweet peas. Check at the picture where the seed pod is ringed in red if you have any questions about seed pods. The sweet pea will reward you with increasingly more blossoms if you remove all seed heads as they develop.
Will pea plants continue to yield?
Snap-style green peas should be harvested before the peas become too big, but when the pods begin to sag. The entire pod can be consumed when picked at the proper time. Pods that are rough and chewy have been left on the vine for too long. Put the peas in the shell and the pods in the trash. As long as the vines are strong and the weather is chilly, peas will produce. Soil mulching keeps roots cool. Pea season ends when the temperature soars into the eighties.
You will have to pick more peas as you pick more of them. Peas lose some of their sweetness after harvest when the sugar converts to starch. Cook or freeze peas as soon as possible after gathering them for the finest flavor. Put the pods of green peas in plastic freezer bags to freeze.
You can also gather edible blooms and green shoots from snap-style pea vines. Although snap-style green peas are occasionally referred to as sweet peas or sugar snap peas, it’s crucial to keep in mind that they are distinct from sweet pea vines grown for their decorative blossoms. They aren’t edible sweet peas.
How old are pea plants?
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.
Can pea shoots grow again?
You might be able to reap another harvest from some of the pea shoots. And they’ll be ready to eat in two to three weeks! Pea shoots may typically be harvested from a box like this over the course of a week or two.
