As soon as the ground can be handled, sweet pea seeds can be planted immediately into thoroughly loosened soil. The seedlings of peas should be thinned to a distance of 5 to 6 inches (12.5 to 15 cm) apart once they have sprouted to a height of 3 to 4 inches (7.5 to 10 cm). Wait until sweet pea plants are 4 to 8 inches (10 to 20.5 cm) high before pinching them. Use your nail as a blade to snip off the growing tip that is located between your forefinger and thumbnail. The plant hormones known as auxins will be forced to the side or auxiliary tips of sweet peas by pinching them out. The auxins will result in expansion and the development of new, stronger growing tips.
Sweet peas can be pinched out to produce more blossoms for cutting. One of the wonders of raising these lovely vines is that. Don’t be hesitant to pinch out your sweet peas to enjoy the bouquets since the more flowers you cut, the more will grow.
Do sweet peas need to be pinched out twice?
No, other than the fact that my grandparents planted sweet peas and I wanted to grow some as well, this has nothing to do with family history.
Because I don’t have a personal or gardening blog, I’m posting this here to share my images with anyone else learning how to grow sweet peas so they can understand pinching out what to do and why. I searched online for images similar to these that would demonstrate what to look for and the final product but was unable. So, I’m hoping they’ll be helpful for someone who was in my position!
It is advised to pinch out to encourage the plant to get bushier and to produce more flowers. It’s debatable when you should do it. The Sweet Pea Society website (yes, there is one! ), as well as the package of seeds I purchased from Thompson & Morgan Heirloom Mixed, all advise pinching out after two pairs of leaves have opened. I watched a few videos on how to pinch out, and the instructions varied depending on whether three or even four pairs of leaves had opened. However, I ultimately made the decision to follow the instructions on the seed packet, and I’ve been pinching out once the plants have two opened pairs of leaves.
Image 1: This sweet pea has not yet had its pinch removed. It has two pairs of leaves, and you can see a sharp part right where the top pair of leaves are. The growing tip is this. I’ll pinch out the tip with the nails of my thumb and forefinger after a couple of days once it has grown a little further from the top pair of leaves. To harm the plant feels cruel, and it also seems risky—what if I accidentally kill it?—to do so. But do not worry—you are about to make the sweet pea extremely happy!
Picture 2: There is no growing point visible on the stem right above the top pair of leaves. It is gone. The sweet pea remains somewhat spindly, much like it did before the tip was removed. Things start happening after a few days, but they will eventually…
Image 3: I tore this one out just a few days ago—probably not more than a week. Three fresh shoots are barely beginning—one at the base and one at each point where the stem and leaf pairs meet. Additionally, I’ve seen that the stem thickens and develops a black line in the centre at this point. It might have been there before, but it’s definitely more obvious now.
Image 4: Ta da! A little over two weeks ago, I extracted the first one. Just take a look at those side shoots; the stem is much thicker! The one rising from the base is already half as tall as the original, and the two others rising from the leaf pairs are giving a great performance.
The thought of planting the sweet peas outside is quite exciting to me. For them, I’ve already prepared a pot with a cane wigwam, and I’m using a stylish metal screen that’s ideal for climbing up.
After removing the tendrils, the plants will need to be clipped with sweet peas to assist them climb. Getting rid of the tendrils should help the plant grow taller and produce more blossoms, at least that’s what I’ve read. After having success with pinching out the tip, I’m going to try it even though I wasn’t sure I would want to.
From Thompson & Morgan, I also purchased some geranium plugs. They resembled dollhouse plants due to their absurdly small size, which is necessary for them to fit through a letterbox. On the recommendation that it will make the plants stronger, I also removed a few of them that had just sprouted their first buds. If I hadn’t learned from the sweet peas that it’s a really excellent thing to do for the benefit of the plant, I might have been afraid to do it.
How can you prevent leggy sweet peas?
Place your wigwam frame in a well-lit area where you can easily access flowers.
If planting sweet pea seeds sounds like too much work, you can always get sweet pea plug plants to get a head start. Due to the fact that slugs adore the young, new shoots, set them somewhere bright and keep an eye out for them.
Your seedlings will start to grow tall and lanky as they mature. Pinch out the plant’s tips to induce the production of side branches. Simply use your fingers to cut off the stem’s top just above a group of leaves. Each plant will become much bushier and stronger as a result. Additionally, the plant will produce more blossoms the more shoots there are!
Should peas be pinched out?

If you wish to create a similar pattern, keep in mind that PVC plastic (recycle number 3) releases hazardous chemicals into your soil. Look for a secure substitute.
In order to reduce pest and disease issues, dwarf or bush peas grow better when supported by bamboo canes or sticks that have been clipped.
Plant dwarf peas in a hanging basket to grow down for simple picking if you don’t have any vertical supports.
Tips for Growing Peas
- Peas are an inexpensive crop to farm since they are light feeders and make their own nitrogen in the soil. Don’t overfeed your soil; else, plants will only produce leaves rather than flowers and pods.
- Garden peas, snow peas, and sugar snaps are all legumes in the Fabaceae family. With the aid of bacteria near the roots, they assist in “fixing” nitrogen in your soil so that it is in a condition that your plants can easily absorb it. These soil microbes transform atmospheric nitrogen into plant nourishment. Really nice, huh?
- Legumes (like peas and beans) are a great way to nourish and enrich your soil without using fertilizer! also saves you money.
- Peas have shallow roots, therefore use mulch effectively to keep the soil moist and prevent weeds.
- Watering: While flowers and pods are forming, keep the soil moist. To ensure their proper development, this is essential.
- When the first pods are ready to be picked and used to salads, pinch out the shoots at the top of each plant. By doing this, the plant is encouraged to produce additional pods.
Crop Rotation for Peas
After growing peas, plant leafy greens or a fruiting crop that requires heavy feeding, such as tomato, capsicum, chilli, eggplant, or potato, to make the most of the free nitrogen in your soil.
Rotating crops from several families in the same container or garden bed will greatly reduce the risk of fungus illnesses.
Prepare your ground
It is crucial to prepare the ground. Early in the year, make a deep soil excavation and add a decent all-purpose base fertilizer. The optimal time to add organic material and well-rotted manure is in the previous autumn. In the spring, if you mix too much, you can end up with more stems and leaves than blooms.
Put up a good support.
Ideal supports for plants to climb up are sturdy canes or hazel poles that are 2 meters (6 feet) in height. You need a sturdy, stable structure that gives the plants on all sides access to direct sunshine. In the shadow, sweet peas do not do well.
Always sow sweet pea seeds in deep pots or tubes
If the plants are to grow successfully, they must build a long tap-root system. Make sure you can transplant without harming the roots no matter what you choose to use. From April on, you can seed directly into the open ground, although few areas have soil that produces the best crops when grown this manner.
Planting out
Seedlings should be planted out as soon as they are big enough (about 5 cm, 2 in) and should be protected from birds, slugs, and snails. Sweet peas are quite hardy and benefit from chilly soil to develop more effectively. Too much time spent indoors weakens the plants and draws them in.
Tying sweet peas
As the plants begin to grow, carefully secure them to the canes or poles with flexi-tie (that flexible plastic tie) or soft string. Sweet pea rings made of delicate wire can also be used. Avoid damaging or breaking the stems.
Cutting back tendrils
Although it is not necessary to cut the tendrils, doing so keeps them from tangling with one another and the flower stems. Flower stems that have tendrils wrapped around them become bent and curled, making them unusable for cutting.
Watering is essential.
Bud drop and stems devoid of flowers are the results of dry soil at the roots during bud formation. This typically occurs at the start of the growing season when there has been some precipitation and the grower assumes that the soil is sufficiently moist; it frequently isn’t.
8. Continue to cut flowers
Continue pruning as the blooms bloom to encourage more blossom production. Never allow seeds to mature on plants. Sweet peas should be considered an annual. If seeds grow, they signal to the plant that its task is complete, and the plant begins to wither.
Feed your sweet peas
Feed with a general liquid fertilizer as soon as the plants begin to grow after planting out and throughout the growth season. Ideal fertilizers include those made for summer bedding plants or tomatoes. Dried Blood was my mother’s recipe for success, and it always seemed to work. Organic gardeners might want to give it a try.
Extend your sweet pea growing season
Keep in mind that sweet peas were historically planted in the fall outside in cold frames or unheated greenhouses. This means that the plants can be planted out early the next spring to give you earlier flowers because they are well-developed. For a longer flowering season, it’s worth growing half this way and half from a spring sowing.
So which varieties will I be growing?
I was overjoyed to discover “Wiltshire Ripple” among Suttons Seeds’ offerings. This was growing alongside the wonderful deep maroon “Beaujolais” in Harlow Carr, and the two were magnificent together. I also like Suttons Seeds’ “True Fragrance,” a frilled and flecked blend.
I especially adore the heirloom sweet pea variety “Prince of Orange,” which contrasts nicely with the deep purple-blue “Cupani.” Try Sweet Pea ‘Juanita’, a vibrantly colored combination of some of these strongly scented blooms, if you enjoy the notion of these fragrant Heirloom variety.
Last but not least, “Noel Sutton” is essential to me for it to be sweet pea time. The ideal Sweet Pea is this large-flowered, frilled, fragrant, soft blue kind; it is everything you would want in a flower of this caliber.
Choosing sweet peas and perennial peas
The major consideration is whether or not aroma is crucial to you when deciding between perennial Lathyrus and sweet peas. Decide if you would then like an annual or perennial plant. There are several color choices available as well as climbing and bushier varieties.
Fragrance
Choose sweet peas (Lathyrus odoratus), which are generally very fragrant, if you enjoy a pleasant garden and sweet-smelling flowers for indoor use.
Lord Anson’s blue pea (Lathyrus nervosus), a perennial Lathyus, is an exception to the rule since it does have a perfume.
How long the plant lasts
After setting seed, sweet peas (Lathyrus odoratus) only have a one-year lifespan. However, don’t let this deter you because they are quite simple to grow from seed. Lathyrus latifolius is an example of a perennial species that returns every year, however there are fewer options and they typically lack smell.
Colour
The annual sweet pea (Lathyrus odoratus) has a large variety of blossom colors, including bicolored varieties. However, the perennial varieties do come in some uncommon colors, like yellow and orange.
Habit
The majority of Lathyrus are climbing plants, therefore support them with canes, netting, or allow them to climb over a bank or through a bush. For ground cover and pots, clumping varieties like the spring-flowering Lathyrus vernus and dwarf bushy sweet pea varieties like “Snoopea” and “Bijou Mixed” are excellent choices.
When to plant sweet peas and perennial peas
- Annual sweet peas should be sown either in late January or early April and planted out in April.
- Sow perennial Lathyrus in the spring or the fall.
Where to plant sweet peas and perennial peas
Locate a sunny area where there is room for the plant to grow or to bush out (depending on its habit). Also acceptable is a little light shade, especially for Lathyrus grandiflorus.
How to plant sweet peas and perennial peas
- To avoid cold shock, indoor seedlings should be hardened off for 10–14 days before being transplanted outside.
- Ideally, four weeks before planting, enhance the soil by incorporating a soil conditioner like garden compost or manure.
- Sprinkle general-purpose fertilizer, as directed on the pack, into the area where you plan to plant it, such as Growmore, Vitax Q4, or blood, fish, and bones.
- Before planting, water your plants thoroughly to hydrate the roots.
- Remove pots from larger plants and ease seedlings out of modules or pots while being careful not to snap or crush the stems.
- Plants should be separated by 20–30 cm (8–1 ft).
- Place climbing plants near to their intended support (within 5-7.5cm or 2-3in), with two plants at the foot of each cane if they are climbing a wigwam.
- After planting, water once more to help the soil surrounding the roots settle.
Use garden twine or sweet pea support rings to secure young climbing plant shoots to canes, pea sticks, netting, trellis, or shrub shoots that they will be growing up. Tendrils in contact with supports will naturally start to cling on, but if any are straying or in danger of snapping, keep tying in new shoots.
In dry weather, check on plants in the ground every 3 to 4 days and on those in containers every day because they won’t flower as well if they become too dry. Each time you water, be sure to use enough water to completely moisten the roots.
Apply a high potassium liquid fertilizer, such as tomato feed, once or twice a week on light or infertile soils. This promotes flowering, particularly in annual sweet peas (Lathyrus odoratus).
Pick or remove dead flower heads as frequently as you can once flowering starts. For annual sweet peas (Lathyrus odoratus), which will stop flowering if seedpods are allowed to form, this is especially crucial.
Pinching out
When plants are around 7.5 to 10 cm tall, pinch out the shoot tips of new spring-sown sweet peas for gardening (3-4in). This promotes robust side branching. Autumn-planted seedlings frequently naturally branch.
Cordons
Pick the strongest shoot and keep pinching out all the tendrils and other sideshoots as they grow whether you want to enter your sweet peas in a local show or just want to maximize the size of blossoms for cutting. By using this technique, the plant directs its attention to the blossoms. The term “cordons” is used to describe these single-stemmed plants.
One stem per bamboo cane or tall stake needs to be tied to them on a regular basis. To keep the shoot in place as it grows, you can use twine looped in a figure-eight pattern around the cane and stem. Use sweet pea rings, which are wire loops that wrap around the stem and cane and are lightly squeezed until they hold, to make things simpler.
Cordons have the potential to grow much taller than the typical 2 m (6 1/2 ft) estimated height.
Cutting back
Cut perennial Lathyrus back to the ground in the fall, or better still, wait until February to do it so the dead stems can serve as wintertime cover for wildlife. When flowering is ended at the end of the summer, annual sweet peas can simply be pulled out and composted. This might happen a little bit sooner during hot, dry seasons.
Methods
Sweet peas can be immediately sown into the ground in April, or they can be planted in seed compost pots in the fall or spring. Although it takes more time, pot-sowing is typically more dependable than direct sowing. If you plant in the fall to enhance your chances of getting early blooms, keep seedlings in a coldframe or cold greenhouse over the winter to protect them from growing lanky. Keep the coldframe’s lid elevated unless a strong frost is anticipated. Sweet peas planted in the spring flower in 12–14 weeks.
Sweet pea seeds frequently have a tough outer covering that makes them more challenging to germinate. Place your seeds on a layer of damp vermiculite or kitchen tissue and store them in an airtight container in a warm area. As soon as the seeds swell or start to sprout, plant them. Some gardeners like to soak the seeds overnight instead, but if you don’t plant them right away thereafter, they might rot. With a sharp penknife, chip off a little portion of the hard seed coat to allow moisture to enter and promote germination on recalcitrant seeds that haven’t swelled.
- Individually sow seeds in seed compost-filled rootrainers or 9 cm (3 in) pots. As an alternative, sow five to seven seeds per 13 cm (5 in) pot, spacing them 2-3 cm (3/4-11/4 in) apart.
- Add 1 cm (1/2 in) of vermiculite or compost to the top of the seeds.
- Add water and maintain at around 15C. (59F)
- It is optional to cover the pots with clear polythene or glass to reduce the likelihood that they will dry out, but keep in mind to remove the covering after the seeds have germinated.
- Once they have grown to around 3.5 cm (11/2 in), carefully transplant single seedlings into 9cm (3 in) pots if you have seeded them several to a pot.
- Use your thumb and finger to pinch out (remove) the top of the shoot just above a healthy leaf when the seedlings are 7.5–10cm (3–4in) tall. This will promote side branches, which are always stronger than the core stem that has been removed.
- At least four weeks before planting, remove all weeds from the soil and add a soil enhancer, such as garden compost, manure, or composted bark.
- Only plant seeds as the soil begins to warm, typically around April.
- To create a wigwam, plant any temporary supports, like pea sticks or bamboo canes, in the ground.
- Take out a shallow drill of dirt 2.5 cm (1 in) deep for rows of sweet peas, and plant a seed every 5 to 7.5 cm in it (2-3in)
- Seedlings should eventually be spaced 20–30 cm (8–1 ft) apart to provide the plants enough room to flourish. The extra seedlings may seem like a waste to compost, but unless treated carefully, their roots are typically too damaged to recover.
- Push two seeds into the ground at the base of each cane to a depth of 2.5 cm (1 in) when sowing around a wigwam of canes.
