The perennial pea germinates similarly to annual peas, with the exception that they are always sown in the spring. In seed trays or other small containers, sow whenever between February and March using a compost without peat. It will take roughly 10 days for seeds to germinate if kept in a warm environment of 18C.
When the plant is big enough to handle, pot it on, then take it outside to gradually harden off before planting.
Sweet peas can be planted outside when?
Sweet peas should be planted in a well-drained but moisture-retentive soil in an open, sunny location. Sweet peas are ideal for container gardening. utilize a compost that is good, peat-free, and has a slow-release fertilizer added in.
How to sow sweet peas
From seeds, sweet peas are simple to grow in the spring or autumn. If you are planting in the fall, make sure you have space for them to grow until spring in a frost-free location.
Sweet pea seeds sprout fairly quickly. However, by nicking the seed coat with a knife and avoiding the “eye” region, you can encourage germination. Either plant seed in trays, root trainers, or 9cm pots (3 to a pot). Place the seed in a cold frame or greenhouse after sowing it in high-quality, peat-free compost.

Planting out sweet peas
Once all risk of frost has passed, you can start planting your sweet peas in late May. Put them outside throughout the day and bring them inside at night to harden them off before planting. When young sweet pea plants are around 10 cm tall, pinch out the tips to promote bushy growth.
In the spring, you can purchase sweet pea plug plants. Under a support, such as a wigwam made of bamboo canes, plant them in rich soil. The average sweet pea will reach a height of 2 meters. Until they have a healthy growth, water them well. Don’t worry about separating individual plants; simply space sweet pea plugs or pots about 20 cm apart.

Can you cut everlasting sweet peas for cuttings?
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.
Can sweet pea seeds still be started?
Nothing is more pleasant for a gardener than planting sweet pea and other flower seeds in the winter. Getting out my sweet pea seed packets and seeing them germinate and sprout indoors is the most delightful thing to do when there is not much happening in the garden itself and I have been spending days indoors due to the cold, wet weather!
Therefore, if you’ve been considering that the only thing you can do for your garden is sit and observe it from the window, reconsider your position.
Early planting of sweet peas will repay you with delightfully scented and eye-catching blossoms. Sweet pea seeds must be started in late winter or early spring if you plant in a zone 7 or colder climate. Don’t hold off till the last frost! Generally speaking, you should start your seedlings inside 6 to 8 weeks before the final anticipated frost.
It might be too late to grow sweet peas and get decent results if you wait until after your final frost. In other regions of the nation, spring lasts only a few weeks before temperatures suddenly rise. Sweet peas require lower temperatures to grow well.
Sweet peas—can I plant them in January?
The world is still a cold and dreary place even if we may have thrown open the doors to usher in the new year with a loud chorus of Auld Lang Syne. The countryside is still barren and the light is still dim and murky.
Despite this, the start of a new year brings with it a strong urge to plant and develop, and patience may be a challenging animal to tame.
But this year, after diving into the amazing world of flowers, I’ve discovered something that can just barely grate that itch, sweet peas.
I’ve discovered that I’ve already contracted the sweet pea bug since sowing my first batch of Lady Salisbury sweet peas in October.
By the time the temperature and light levels began to fall in December, the plants that were sowed in the fall had grown to a height of about 3 inches.

I feel compelled to learn everything there is to know about anything new I take up. I read a lot about what would be the preferred flower in the gardening world over the winter.
Maybe we can encourage the next generation to appreciate these treasures in a similar manner that craft beer and sherry have experienced a comeback and are currently fashionable? (As I type, I’m caressing my hipster beard!)
An organization that supports these lovely blooms is called the National Sweet Pea Society. I’ve learned that its website is a great place to learn about events, learn about the history of the plant, and get advice on how to cultivate sweet peas.
When choosing the kinds of sweet peas you might like to cultivate on your plot, the website’s amazing collection of blooming sweet peas is a great resource.
However, Graham Rice’s The Sweet Pea Book was my favorite discovery. Over the holiday break, I read this book quickly after purchasing it. I enjoy reading it.
This is a thorough tutorial for someone who is completely new to sweet peas, yet the narrative is easy to follow and doesn’t make you feel like you are reading a textbook.
Even though I haven’t grown sweet peas for a season, I’m delighted about them. On the other hand, there’s something about this flower that makes me ecstatic to grow it on the allotment this year.
I’m especially drawn to the idea of bringing home fresh flowers that I can arrange in a vase as a lovely accoutrement to the homegrown vegetables we’ll be eating.
This month, I’m planting a second batch of sweet peas. More Blue Velvet and Lady Salisbury. By limiting my selection to only two varieties, I want to ease into producing sweet peas. A vase filled with these blooms will make a straightforward yet eye-catching presentation, in my opinion, due to their stunning color contrast.
Sweet peas are relatively simple to handle because of their large, rounded seeds. They remind me of the edible silver balls that are used to garnish cake tops, except that they are neither silver nor edible.
Annual sweet peas can be seeded in the spring. A January seeding allows the plants to form strong roots, show some early growth, and produce larger plants to set out after the frosts, just like an October sowing did.
Sowing seeds in the middle of January does feel terribly weird. But it’s a widespread practice, particularly in Britain. They have an advantage over those that were sowed in the spring because they were sown earlier, and strong, healthy plants will always prevail over fresh seedlings in the battle against those annoying slugs.
I’ve never had much luck with sweet peas, but I’m well aware of the controversy surrounding the pre-sowing method. Should the seed case be “chimped” to promote germination? Is it beneficial to soak or “chit” the seeds before planting them?
The reality is, according to a reliable source, you only need to poke the seed into the ground for it to sprout. To assure greater results, it could be worthwhile to spend a little more time and apply the aforementioned strategies.
I planted the sweet pea seeds in two 5 inch pots in October. I’m planting each sweet pea seed this time using toilet paper tubes because I’ve learned more.
First off, a 2007 piece in The Telegraph said that we Brits were setting the standard for toilet paper usage. The data showed that Britain’s toilet paper consumption, at 110 rolls per person, was 25 times more than that of Ukraine, which had the lowest usage in Europe.
There are a lot of empty cardboard tubes and bottom wiping involved. Recycling is encouraged. However, they make excellent DIY seed pots.
Second, if you start the seeds in a pot, you’ll need to separate each plant from the massive root ball that has grown by the time you’re ready to put the sweet peas outside. No matter how carefully you do it, some root damage will always result.
Of course, such root injury has very little impact. Only the purist in growth would notice, I’m sure. But perhaps when it comes to our blooming, we should strive to be as professional as we can? Thus, root trainers or modules receive the highest grades.
Root trainers are reusable and quite inexpensive to purchase. I would not have any issues with getting a few packs. However, as I’ve already mentioned, we are drowning in cardboard tubes as a result of how much toilet paper we use.
In terms of root protection, cardboard tubes offer the same advantage as commercial root trainers, but they are also biodegradable. As a result, you can plant the sweet peas outside, pot and all.
Shake the tubes as you fill them with seed compost, then firmly push the compost down. Create a hole in the compost, place the seed inside, and then cover with a thin layer of compost to neatly tuck them into bed. After giving them a good soak, place them in a small greenhouse.
As I previously did with the October-sown sweet peas, I’ll pinch out the January-sown plants when they reach a height of about 3 inches.
Doing this is not difficult in any way, as far as I am aware. The first time I did this, I was terrified as well! Simply pinch off the top of the sweet pea seedling above a leaf joint using your finger and thumb.
It’s nice to be outside planting something that will eventually bloom this year. I’ll be patiently looking for the first indications of tiny shoots breaking through. But just now, I’m returning inside to wrap my hands around a steaming mug of tea.

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.
When do you sow your peas?
Nothing compares to the delightful flavor of peas straight from the garden in terms of sweetness. They are fresh candies from nature! One of the earliest crops of the year, peas are planted as soon as the land can be worked, even if snow follows. See our growing advice for peas, from planting to harvesting!
About Peas
Peas are incredibly simple to raise, however they only have a very short growing season. It’s crucial to plant them in the springtime early enough for them to mature while the temperature is still cool. (This refers to planting in most of the United States and Canada in February, March, or April.) In warmer areas, they can also be cultivated as an autumn or winter crop.
Enjoy the flavor of peas as soon as you can because they don’t keep fresh for very long after harvest. The taste of the peas you get in grocery shops, which are frequently starchy, is incomparable to garden-fresh peas.
Most garden and culinary requirements can be met by three types of peas:
- The seeds (peas) of sweet peas, also known as garden peas or English peas (Pisum sativum ssp. sativum), are extracted from inedible pods.
