- Sweet peas can be seeded in the fall in warmer places (Zone 7 and above) where the winters are generally not too harsh. Other than that, plant seeds in late winter or early spring. Before planting, give the seeds a 24-hour soak in water. By doing so, the seed coat is softer and the sprouting process is accelerated.
- Fill your planting containers with high-quality potting soil while the seeds are soaking. Use the deepest pots you can find because sweet peas develop a lot of roots. Ideal containers are 4-inch (10-cm) pots and root trainers.
- In each container, plant two seeds by pressing a fingertip into the soil and a half-inch (1.25 cm) deep.
- To boost humidity and hasten germination, cover pots with a plastic dome covering. Place in a warm greenhouse or a house window with good light.
- Pinch out the center growth tip, just above a leaf joint, once plants are 4 to 6 inches (10 to 15 cm) tall, leaving just two or three leaf nodes. The plant will be encouraged to branch out strongly from the base as a result.
- Because they use a lot of food, sweet peas need a little more care to produce in large quantities. Apply bone meal, a thick layer of compost or well-rotted manure, and a generous amount of natural fertilizer to planting beds to prepare them. Incorporate these elements thoroughly into the soil.
- Vines require a sturdy foundation to climb and grow quickly. Affix Hortonova netting or 6-foot (1.8 m) tall metal fence to the tall poles spaced approximately 8 feet (2.4 m) apart down the row for them to climb.
- Around the time of the final spring frost, plant seedlings outdoors in two rows, one on either side of the trellis, spaced approximately 8 inches (20 cm) apart down the row. It’s crucial to keep the vines bound to their supports as they erupt into lush growth. Sweet peas can grow more than a foot (30.5 cm) per week once the vines begin going.
- Sweet peas adore water, and they can’t survive without regular watering. Set up soaker hoses as soon as you plant them to prevent their luxuriant development from being restrained. It’s important to maintain their thirst quenched during warm weather. Use diluted fish and seaweed emulsion to feed plants once a week.
- Pick flowers when there are at least two unopened blooms remaining on the stem for the greatest vase life. To extend the life of the vase, add flower food to the water. It’s crucial to prevent plants from going to seed in order to prolong blooming, so be sure to regularly harvest and deadhead the flowers.
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 decorative metal screen that’s ideal for climbing up.
After removing the tendrils, the plants will need to be clipped with sweet peas to help 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 to pinch out sweet peas
As soon as the ground can be handled, sweet pea seeds can be planted immediately into thoroughly loosened soil.
According to Garden Know How, pea seedlings should be spaced five to six inches (12.5 to 15 cm) apart once they have sprouted to a height of three to four inches.
Wait until sweet peas are between four and eight inches tall before pinching them out.
Then, using your nail as a blade, cut off the growing tip that is between your forefinger and thumbnail.
What occurs if sweet peas are not pinched out?
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.
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!
When ought one to pinch out?
The phrase “pinching out” may have been used in relation to your dahlia or tomato harvest. Although it is a widespread practice among gardeners, careful consideration is required to use this technique efficiently.
Pinch out, in its most basic form, is a technique for pruning young plants to promote branching that will eventually bear more fruit or flowers, increasing the output. The plant will physically branch out to produce new stems and branches if the uppermost portion of the stem is practically pinched off just above leaf nodes or buds.
Pinching has a few additional advantages as well. First off, pinching stops your plants from growing excessively long and lanky. You can build a stronger central stem by promoting growth in the lower branches. Second, regular pinching will keep plants from coming to seed too early on those plants that are primarily grown for leaves (like herbs), ensuring that the foliage remains lush and full. Coleus and other plants with ornamental leaves can be plucked to get the same effect.
How to pinch out
Quick Advice for Cutting Back:
- Don’t hurt the leaf nodes that are underneath the pinching point. The best way to pinch is with your fingertips or a pair of sharp scissors or snips.
- Stop pinching too soon. Wait until the plant has grown strong enough to survive pruning and at the right height.
- Recognize when to stop. The longer you have to wait for flowers or fruits, the more you are pinching out. Overpinching can also result in highly bushy plants with crowded blooms.
The early growth can be readily removed by pinching it between your fingers because it is so delicate, but if you like, you can also use snips. Regardless of the technique you employ, avoid damaging the leaf nodes because doing so will make it difficult for the plant to develop new branches. If desired, you can repeat this procedure on the new branches as well, but avoid developing a habit that causes over-pruning. To prevent illness from spreading to the stem, be sure to pinch just below the leaf nodes.
Once the plant has taken on the correct shape, stop pinching it out and let it flower naturally. The blossoming will be postponed while you are working on pinching out, but this is done so that the plant will be fuller and produce flowers and fruits later in the season.
Young plants are the best candidates for pinching out because adult plants may suffer health effects. When to pinch out a plant depends on the type of plant, therefore it is better to verify if you’re unsure. Some plants may experience limited growth as a result of early pruning, and young plants may become destitute if too much foliage is removed; the plant needs enough foliage to carry out photosynthesis and flourish.
The plants did actually become bushier last year after I started cutting off my dahlias far too early, but the stems were stunted and the blooms were so close together that many pests opted to make a home there. I spent a lot of time attempting to correct my error, but some of the petals never fully opened up. The lesson of the story is to know when to quit pinching and not to pinch too soon.
Pinching Tomatoes, Dahlias & Basil
Plant species that typically only produce one main stem are the ones that are typically pinched. Basil, dahlias, and cordon tomatoes are some of the favorites of gardeners that are frequently snipped. See more instances of plants that can benefit from pinching out by scrolling down. The following advice is for the favorites:
Pinching Out Tomatoes
Tomato types that are indeterminate respond to pinching quite well. These tomato varieties include “Gardener’s Delight,” “Sungold,” “Beefsteak,” and “Sweet Million.”
Once your tomatoes have at least six sets of genuine leaves, you can begin pinching them out. Instead of pinching from the top, you want to prune the side shoots because you want the main stem to continue growing for a considerable amount of time. (Insert canes to provide assistance as they climb vertically.)
Tomato sideshoots are those that emerge at a 45-degree angle from the main stem and branches. The plant will be forced to focus its energy on the main stems and fruits if you pinch out the sideshoots.
You can stop the main stem from growing after your cordon tomato plants have grown to their full height by pinching off the top below the highest flowers. To achieve the healthiest harvests, it is advised to have no more than seven trusses (stalks with several flowers that will develop into fruit) on the plant.
Additionally, now that you know how, it’s crucial to refrain from pinching out all of your plants. Pinch outs are only beneficial to some plants while being actively harmful to others. Do not pinch back your bush tomatoes since determined tomatoes (also known as bush tomatoes) will yield fewer fruits if you do.
Pinching out Dahlias
Before you start pinching, wait until the main stem is about 12 tall and has at least four sets of leaves. A dahlia plant will become squat and densely bushy if the stem is pinched out while it is still short. When the flowers begin to bloom, they will swarm one another, which can invite pests and diseases due to poor air circulation. It will be more difficult to notice the lovely blooms as well.
Pinch out the topmost tip of the stems right above a group of leaves. The remainder of the procedure is same. Cutting and deadheading the flowers after they bloom also encourages healthy growth and additional blossoms.
Pinching out Basil (and some general advice on trimming herbs)
Basil grows bushy and lush with plenty to use in your cooking and responds particularly well to pinching back because it typically grows one central stem.
Always trim the stem down to just above the leaf nodes when harvesting basil or any other herb using the pinching technique. Avoid the urge to simply pluck the leaves off. The plant’s resources will be drained by bare stalks. Cutting the stem encourages root development as well.
For new gardeners learning how to pinch, herbs are a great variety of plants. Regular trimming of herb plants is the greatest technique to promote bushy growth and avoid legginess. Additionally, any branches that are cut become your harvest for cooking.

When Not to Pinch
Not all plants respond well to being squeezed back, and excessive pinching can be harmful to some plants.
Plants that naturally become bushy in growth do not require pruning. All you really do is delay normal growth, which could lead to a lower yield. Tumbling tomatoes, for instance, are a good illustration of determinate tomatoes.
Pinch-out techniques are ineffective for monocotyledons and may even cause the plant’s death. This is due to the unique ways in which these plants store their energies and the fact that pinching removes the developing tip. Alliums, grasses, and the majority of flowering bulbs including tulips, daffodils, and lilies are examples of monocots. Monocots typically rebound from pruning and sent up a new stem to replace the one that was removed. However, you will only receive one; no bushy growth. We must cut the stem of chives, a monocot allium, in order to harvest it, and then we must wait for the stem to grow back. The plant keeps expanding, but the only option to increase the output is to either wait for the bulb to generate offsets that develop into separate plants or to sow new seeds, of course.
NB: For regulated types of development, pinching out can be employed to purposefully limit growth in some plants. For instance, young sunflowers can be pinched to produce shorter stems for cut flowers. However, in most circumstances, this is not advised.
Avoid pinching the following plants:
- Campanula
- Cockscomb
- Delphinium
- Sunflowers
- Larkspur
- Container Tomatoes
- Dill
