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.

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 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 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.
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.
How are seeds prepared for storage?
I wrote a blog post last week explaining the procedure for gathering seeds. The seeds must be cleaned and dried after collection in order to be kept.
Choose a dry day to collect the seeds if you’re collecting them from non-fruiting plants. Spread the seeds out and let them dry for one to three weeks on newspapers, in a box, or inside an old phone book.
The necessity to separate the chaff from the seeds is common (the seed casings and debris). With a pair of tweezers, you can accomplish this; only a small amount of the chaff needs to be removed.
Making a deep crease through the middle of a piece of paper will let you easily distinguish between the chaff and the seeds. To slowly release the contents of the folded paper, place the filthy seeds in the center, tilt the paper slightly, and tap it slowly (very similar to what you do when sowing seeds). When the contents divide, the heavier things will slide down the crease more quickly than the lighter ones. The chaff will fall out first if the grains are lighter and the heavier seeds will glide out first.
When the chaff is lighter than the seed (which is typical), an antiquated method of cleaning is to winnow your seeds. In front of a fan, put the seeds in a basket and fling the contents into the air. The seeds will be let to fall back into the basket as the chaff is blown away. The best course of action is to find a screen that lets the seeds fall through but collects larger pieces of debris—an old tea strainer or colander works well—if the chaff and the seeds are of similar weight.
The process of separating the seeds from the chaff generally involves placing seedpods in an old pillowcase and stepping on them to release the seeds. Place the pods in a bag and crush them with a rolling pin if you have a culinary bent.
Scoop off the seeds from fleshy fruits, wash them, and then soak them in water. After being cleansed, take the seeds out of the water and pat them dry using paper towels. To remove the fleshy coating, many individuals who are serious about collecting tomato seeds ferment the seeds (I’ll go into more detail about this technique in a later blog post).
Make sure your seeds are dry before storing them; otherwise, they will rot. Don’t dry out the seed, though—still it’s alive—just get rid of the extra moisture and keep it dormant until you’re ready to plant it.
Give seeds the exact opposite—a dry, cool, dark environment—when storing them since seeds need moisture, warmth, and light to germinate. Put your seeds in a paper bag or envelope and store them in glass jars or plastic containers. Remove the airtight container step if you are unsure that your seeds are dry. Keep the labels with the seeds, don’t forget.
The back of a refrigerator, a corner shelf in the garage, a cellar, or a closet are all suitable places to keep the seed. The range of 32F and 50F is good for storing seeds.
The general rule for preserving seeds is that the sum of the temperature and humidity should be less than 100%. This indicates that if the temperature is 50 degrees Fahrenheit, the humidity must be lower than 50%. High temperatures and high humidity both promote germination and start the metabolism of the seeds.
On conserving seeds, there are numerous excellent books. The seed-saving instructions produced by Suzanne Ashworth and Nancy Bubel are incredibly educational, and William Cullina’s Wildflowers: A Guide to Growing and Propagating Native Flowers of North America is brilliant.
What is the most effective approach to long-term storing seeds?
When planting season comes around, things may have changed from when we as growers planned our season in late fall and early winter. We might discover that from one season to the next, we have more seeds in our possession than we can plant. Because of water limitations put in place in areas experiencing drought, some farmers and gardeners have even been forced to completely cancel their growing seasons.
High Mowing is aware of the significance of maintaining the quality of your stored organic seeds. A simple approach to guarantee that seeds that didn’t make it into the soil this year will produce robust crops in the future is to keep them viable for upcoming growing seasons. The optimal procedures for long-term seed storage are covered here.
It is wise to keep in mind that seeds are nature’s preferred means of storing things and that, if stored properly, they may frequently be kept for use across several growing seasons. When considering how to store your seeds, you should consider the factors that contribute to and preserve the seed’s dormant state. The most crucial factors to control include temperature, light, and moisture. All three of these environmental elements can promote seed sprouting or even seed deterioration.
The best way to preserve seeds is in airtight containers. The goal is to shield the seeds from unwelcome moisture, light, and pests that could try to settle among your nutrient-rich seeds. This can be done in a variety of methods. For storing loose seeds or even seed packages, mason jars are a fantastic alternative. A Tupperware or other plastic or metal container can be used to store seed packets once they have been sorted in plastic, sealable bags. Placing silica gel packets might help manage excess moisture if humidity or moisture are issues where you live. These tiny sachets are marketed online and are comparable to what you might discover in a pair of mailed shoes or clothing. Season after season, they can be used again.
Temperature is one of the signals that seeds need to start germination. Different seeds will sprout at different temperatures, but as a general guideline, it’s best to store your seeds below 40 degrees Fahrenheit (or lower). This can be challenging to accomplish, which is one of the reasons some gardeners opt to freeze their seeds. This is a simple method for storing seeds for a long time and generally assures that your seed stays dormant. When storing seeds in a freezer, the issue is that if you lose power, you can end up freezing and thawing them, which might cause deterioration. If you have a chest freezer, giving your seeds a lot of room can be helpful. If all you have is a domestic freezer that is connected to your fridge, it might be better to limit your selection to your favorites. When the seeds have completely frozen inside their sealed containers in the freezer, it’s crucial to allow them come to room temperature first before opening the containers. This ensures that the moisture produced by the thawing process does not absorb by the seeds, which could affect their viability.
Due to moisture and temperature changes, storing seeds in the refrigerator can be challenging but is also effective in maintaining quality. Once more, it’s crucial to wait until airtight containers are room temperature before opening them after removing them from the refrigerator.
If you can’t keep your seeds somewhere that is close to the ideal 40 degrees Fahrenheit, many varieties of seeds can be stored successfully for a shorter period of time in a cold, dark environment that is kept between 55 and 60 degrees Fahrenheit. The most crucial thing in this situation is to keep the temperature steady. Temperature changes can simulate the passing of the seasons, which can prompt your seeds to germinate earlier than expected. A seed cannot return to a latent condition once it reacts to environmental cues and begins arranging proteins in anticipation of sprouting. Your stored seeds may experience undesired deterioration and a decline in germination rates as a result.
As you are aware, the first step in planting crops is to water your seeds in. One of the most significant indicators for seeds that it is time to begin developing is moisture, which is necessary for the sprouting process. It’s crucial to control moisture when designing systems for long-term seed storage. You’ll need to discover a technique to keep your seeds dry once you’ve figured out how to keep them cool. As long as they can be sealed, mason jars and other glass containers make excellent seed storage solutions. Other excellent options are zip-top bags, freezer bags, and other plastic containers. It is especially crucial to keep your seeds dry if you intend to store them in their paper envelopes for organizing because the material of the envelope might absorb water and pass it on to the seeds. It is very vital to try to remove as much air as possible when placing seeds or seed packets into plastic bags and to double check to make sure there isn’t any moisture trapped in the bag before sealing it.
Water typically condenses in cold settings, which are ideal for seeds to go into dormancy. Because of this, it’s crucial to use an airtight container and to wait until the containers are at room temperature before opening them. An additional line of defense against failed dormancy and decay is the use of silica gel packets, powdered milk, or rice within your storage vessels to trap moisture that may have made its way into your containers.
You shouldn’t keep your seeds in a well-lit area for the same reason you wouldn’t keep your bag of potatoes there. Another crucial signal for the seed when it is time to sprout is light. It’s crucial to keep your seeds in clear glass and plastic containers in a dark, dry location when storing them. This can be kept in a cabinet, hidden beneath objects that block the light, or inside of another container with thick, opaque walls. Keep sunlight away from your seeds in particular because it can encourage sprouting as well as the natural decay of organic matter, ruining food in the same manner that sunlight can.
Seeds are food as well as possible future plants that can be stored. Pests that harm seeds can be found in a wide range of sizes and shapes. Rodents and insects are some of the worst pests for stored seeds. Rats and mice, in particular, are infamous for consuming hoarded grains and seeds. Your pantry, barn, and other outbuildings will be invaded. It is crucial to make sure your seeds are wrapped inside something rat resistant if you struggle with rodent infestations, as most farms do. This can be a metal garbage can, a Tupperware container that can be sealed, or any other container that will resist the nibbling of tiny, pointy teeth that are persistently present.
Since the harm caused by insect pests may not be apparent until it is too late, it can be very damaging. Beetles, weevils, borers, and moths are a few examples of frequent pests that attack stored seeds. As with rodent pests, prevention is the best way to deal with insect pests. Examining your seeds before storage to make sure there are no stowaways is one approach to prevent pests from invading your stored seed. The next step is to re-seal that container and place it in the freezer for two days if you do discover an insect infestation in some of your seeds. The infestation will be eliminated as a result, and it won’t spread. Limiting the amount of oxygen in the storage container is another effective strategy for avoiding insect pests’ damage of your seeds. Insects require oxygen to survive, therefore containers that are well sealed and have little excess space will help to lessen the bugs’ ability to live there. As long as the seeds are dry, vacuum sealing is a fantastic way to store seeds and minimize insect pest damage.
Despite the fact that seeds can preserve the dormant, embryonic plants inside of them for a long time, they are formed of organic materials and will eventually decompose. The endosperm will eventually degrade even if you are able to retain your seeds in a condition of full dormancy, where the embryonic plant remains motionless and does not begin processing the food (also known as the endosperm) inside the seed coat. Each type of crop has a different breakdown period. Consequently, even under ideal circumstances, seed loss can happen over time, and the rate at which it occurs varies depending on the type of crop.
