As soon as the sweet peas’ brittle, brown shells appear, start preserving the seeds. Sweet pea seedpods won’t germinate if you harvest them before they are fully developed. However, if you wait too long, the fragile seed pods will crack open and scatter their seeds all over the place. The procedure may take a few weeks, so keep an eye on them. You need to immediately pluck the pods if they start to split.
Sweet pea seeds are simple to collect. Remove the seeds from the seedpods and bring the plant inside. The seeds should dry for about three days on a level surface, such as a countertop or baking sheet, lined with newspaper. Once they are dry, store them to maintain their dryness in a freezer bag or Mason jar with a tight-fitting lid. Before planting, keep them in a cool location.
Can you save 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.
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.
Do sweet peas re-appear?
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.
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.
What is the shelf life of sweet pea seeds?
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.
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.

Sweet peas are the perfect plants for you if you enjoy using fresh cut flowers to decorate your home with color and aroma. They are excellent for cutting since they grow more as you take more flowers from them. Using our sweet peas center, you can learn everything you need to know about growing and caring for sweet peas.
Can sweet peas be propagated?
Young sweet pea seedlings can be used as sources for cuttings. It is rather simple to take cuttings and get them to root and flourish if you just have a few plants of a variety and want more but are out of seed.
Young sweet pea seeds, a container of water, tidy, sharp scissors, and rooting hormone are all required. I apply liquid rooting hormone Dip n’ Grow. Without the hormone, I’ve tried rooted cuttings, but the results aren’t as good.
: Choose Your Sweet Pea Seedlings
About two months old and prepared for planting out are these sweet pea seedlings. Before I do, I’m going to cut a 5 inch piece off of each plant so that I may rapidly and readily grow new side shoots to replace the ones I cut off.
: Make Your Cuttings
Cut a 5-inch section of stem immediately above a pair of leaves with a clean, sharp pair of scissors. Dip the cutting for a brief period of time into the Dip n’ Grow liquid rooting hormone solution.
: Place Cuttings In Water
Your sweet pea cuttings should be placed on a warm windowsill that receives some indirect sunshine after being placed in a jar of fresh water. To keep an eye on them, I like to set them on the kitchen windowsill.
: Wait Awhile!
In around two weeks, roots will begin to form. Only 11 days passed between the photo’s roots developing. When roots appear in this manner, you can plant them in a quality potting mix. My rooted cuttings are then placed in an unheated greenhouse.
: New Growth
About six weeks later, the cuttings’ fresh growth is visible, and they are almost ready to be planted outside.
Final thoughts: I started the cuttings from “mother” plants that were begun in the fall (November). Cuttings were made at the end of January, and roots started to appear around the start of February. By the end of March, the cuttings had enough new growth to be planted.
How can the quality of pea seeds be determined?
Raise your hand if you have ever questioned, “Hmmmm, are these seeds any good?” at this time of year as you stroll out into the garage or wherever you keep your seed collection from the previous year or years.
Will they sprout, or start to grow, shoot, or produce buds? Will planting these seeds be a waste of time and effort? My arm is raised. I have leftover flower and vegetable seeds from the previous year, seeds I collected, and seeds that others have given me. Because they were given to us by particular friends and/or loved ones, certain seeds have sentimental value or memories associated with them. What can you then do?
To determine whether the seeds in question will germinate (the process by which an organism grows from a seed or similar structure) or are viable, there are a few tests that can be employed (able to take root or grow).
The water test is one way to assess the viability of seeds. Take the seeds and put them in a water-filled container. Give the seeds 15 minutes to sit. The seeds are still good if they sink; if they float, toss them because it’s likely they won’t grow.
If it is the right time to plant, sow the seeds directly in the ground; otherwise, completely dry them before planting.
From the seed package in question, take at least 10 seeds and arrange them in a row on top of a lightly moist paper towel. Place the towel in a clear plastic bag after folding it over the seeds. Place the bag in a warm (above 70 degrees) position after sealing it. Although most seeds don’t require much light, a warm windowsill or the top of the refrigerator are both good places to start. (Note: Another option is to lay the wet towel out on a dish and cover it with plastic wrap. In this manner, a wider variety of seeds can be arranged in separate rows on the damp towel.
Next, write the date and the kind of seed on the bag’s outside with a permanent marker. If you have a seed packet, check it out and make a note of the germination times. Check the seeds in a few days to determine whether any have sprouted based on the average germination times provided on the seed packet.
Check seeds in seven to ten days if there is no packet. If you’re anything like me, you’ll check them daily—probably more than once—just for fun. Remove the paper towel-wrapped seeds from the bag once they have begun to sprout and count how many have done so. Only half of a sprout will probably germinate if it has only grown partially. Don’t start to panic just yet.
Simply scatter the seeds in your container or garden thicker than usual to solve the problem. The University of Illinois Extension Office advises purchasing new seeds if fewer than 70% of the seeds germinate.
Plan to do the germination test just before planting so that seeds can be planted. To teach kids about germination, here is a fun activity for kids called “Garden in a Glove” for the parents and grandparents out there.
Resources required: clear plastic gloves, permanent marker, five different types of seeds, cotton balls, pencil, twist ties, or string. On the glove, use the permanent marker to have the youngster write their name and the project’s date. Each seed variety’s name should be written on a glove finger. Squeeze the extra moisture off the cotton balls after wetting them. Each cotton ball should contain three to four seeds. Fold cotton ball over to enclose seeds.
Use the pencil to press the cotton ball into the fingertip of the glove with the matching label. Blow air into the glove and fasten the glove’s top with a twist knot or string after all the seeded cotton balls have been positioned. Watch for success by hanging the glove in a window or another warm spot. It should take three to five days for the seeds to sprout. Cut the tops off the gloves to remove the cotton balls once they have germinated, then plant the cotton balls with the seeds in the ground.
Can you freeze pea seeds?
Typically, people will only resurrect a topic if they are in a similar circumstance or have helpful advice to share. Given that it has been six years, the OP is probably already aware of the solution and has forgotten about this post.
Even if the seeds will be planted the following year, beans and peas should be frozen in locations where insects can attack the plants in order to eliminate any eggs or larvae. To kill insects, the seeds must be kept at a temperature of about 0 F for several days, which can be achieved in a standalone freezer. In most cases, the ice box atop a refrigerator doesn’t become cold enough; if in question, test it with a thermometer in the freezer.
The main concern for frozen seed storage is excessive seed wetness, which would significantly harm (or kill) the seed when frozen, rather than overdrying. This is especially true for large seeds that require a long time to dry, such beans and peas. The idea put forth by Dlsm to dry seed with an air conditioner makes sense because an air conditioner reduces interior humidity. In the winter, when my indoor humidity is naturally low, I can dry my seeds by simply keeping them open. However, desiccant is the only workable approach to reduce seed moisture to the correct level if indoor humidity cannot be managed.
Silica gel packs made for different uses can be used again, but you won’t be able to gauge their effectiveness. I advise using color-changing desiccant for seed preservation because of this. (This is occasionally available in hobby shops and is used to dry flowers.) Start off with a quantity that is the same weight as the seeds being dried. Repeat the process with new desiccant until the color stays the same if the desiccant changes to indicate moisture saturation. The seed should be dry enough at that stage to store it frozen without needing any more drying. A little amount of color-changing desiccant should also be stored with the seed in a sealed container; this will provide some further protection and serve as a warning if the seal has been broken by moisture.
There is a decent rule of thumb for assessing tiny amounts of beans and peas for adequate dryness in the absence of a method to precisely detect seed moisture. When a seed breaks when struck with a hammer (while wearing eye protection! ), it is completely dry. (For a comparison, try doing this with popcorn.) It requires additional drying if it is simply crushed, flattened, or the fragments stay together.
Actually, unless seeds are exposed to a drying environment for an extended period of time, it is difficult to overdry seeds.
One more point about freezing storage. The container must get to room temperature before being opened after the seeds have been taken out of the freezer. As with a glass of ice water, moisture will condense on the seeds if the container is opened while cold. The seed could fast sprout or rot as a result of that dampness. If the seeds will be utilized over several years, it is a good idea to separate them into several zip-lock envelopes inside the sealed container. This will allow for the rapid removal of a single packet and the quick freezing of the entire container.
