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.
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.
Will sweet pea seeds keep for the next season?
Heirloom or old-fashioned sweet peas are lovely and aromatic blossoms. Pick an heirloom variety if you want to save seeds. Modern hybrid seeds could be disappointing because they won’t likely resemble the parent plants.
You don’t need to go to the trouble of saving seeds if you intend to grow sweet peas in the same garden location again the following year. The seed pods rupture when they dry, dispersing their contents to the ground. These seeds will produce blossoms during the next year. However, use these simple steps to gather the seeds if you wish to plant them somewhere else or share your supply with a friend.
Stop deadheading a select few strong, lovely plants. The blossoms must stay on the plant until they are dead since seedpod formation doesn’t start until after the flower has died. The rest of the garden’s plants should be cared for as usual, with deadheading to ensure continuous spring flowering.
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.
Can you grow peas from fresh seeds?
You can plant the peas directly into the ground or garden beds once they have germinated. The peas are placed in a small trench in the ground, normally spaced about three inches apart. We’ll cover them, use our hands to gently press down on the ground, and then spray them with water. Here is my step-by-step guide for planting peas.
You then have to wait for the first one to emerge through the ground, which typically takes more than a week. It’s a thrilling period when you’ll rush to the garden every day to watch the first one. The others will emerge rapidly after the first one.
Should I dry the peas before planting them?
Once you’ve finished gathering pea seeds, make sure to properly dry them off before storing them. It’s crucial to dry pea seeds before storing them because else, they can mold.
Simply leave the seeds outside for a few days until they are completely dry. Pea seeds should be totally firm after drying.
Pea seeds can be dried and kept until spring in a plastic container (film canisters work excellent for this!). They can also be kept in paper bags or little envelopes.
You can construct your own seed envelopes if you want to share your seeds with others, or you can take it a step further and get personalized envelopes—how fun!
I keep my seeds in a transparent plastic container, however a Seed Keeper may be ideal for you if you prefer to organize your seeds more effectively.
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.
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.
How are sweet peas multiplied?
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.
