What is the most effective method for moving a sweet pea plant? The vine has been growing for around 28 years.
Sweet peas can be transplanted in the late summer or early spring. Gardeners in the north might want to transplant their plants in the early spring so they have time to re-establish before winter. Southern gardeners might prefer to transplant in the fall to give their plants time to settle in before the summer heat. Cut the plant back to approximately a foot when it’s time to transplant, then divide it into many pieces after digging. Plant the divisions at a spot that has been suitably prepared. To keep the roots cool, wet, and insulated in the summer and during the winter, give the soil enough of water and mulch. When the ground freezes, northern gardeners may choose to cover late-fall transplants with straw or evergreen boughs. The newly transplanted sweet pea will benefit from the additional insulation over the winter.
How is a sweet pea plant transplanted?
When to Plant: Sweet peas can withstand light frosts, therefore in cold winter regions, sow in seed starting pots in early spring approximately 6-7 weeks before the final day of frost. Then, plant out as soon as the soil can be handled.
Sweet pea seeds can be directly placed into the garden in the fall from September to November in mild winter settings where the ground does not freeze. This will allow the seeds to develop healthy root systems and bloom in the spring.
If you give your seeds a head start by sowing indoors in seed containers from late January through March and transplant into the garden as soon as the soil can be worked, you can still receive a decent harvest of sweet peas, even though they will bloom a bit later. Sweet peas can handle light frosts.
1. Before planting, you could decide to nick your sweet pea seeds. The seed’s outer layer can be broken off by giving it a quick cut with a nail clipper so it can quickly absorb water. This will result in a higher percentage of your seeds germinating and a few days earlier sprouting.
This is how: Between your thumb and forefinger, hold a seed. Clip your seed by holding the clippers at an angle with the other hand so that you can only utilize the tip of the blade. Not taking a chunk out of the seed is your goal; it is to slice through the brown top layer of the seed. Sometimes the nick you caused is barely visible, and other times a bit of the seed coat cracks off revealing the interior seed’s lighter color. Both are true.
2. Avoid using garden soil when planting sweet peas in containers. Use high-quality potting mix instead. Using garden soil can lead to issues like compaction and poor drainage, whereas potting mix recipes are designed to perform under the circumstances found in a small container. In garden centers, a variety of soil mix brands are easily accessible.
Before filling your container, always pre-moisten your potting mix. As you slowly pour water into a bucket or wheelbarrow and stir the dirt, the earth will become evenly moist. When it feels like a wrung-out sponge, you are finished.
A 3 to 4 inch container works well for starting sweet peas. To prevent spreading disease to your new soil mix, properly clean the pot before using it again. After adding the pre-moistened mixture to the pot, give it a quick tap on the work surface to settle the soil. When a pot is filled correctly, the soil surface will be about 1 inch below the container’s top.
3. The time has come to plant your seeds. It matters how deeply you plant them. Always adhere to the planting depth recommendations on your packet’s back. Make a hole that is 1 deep for sweet peas. For this, a pencil or your finger works great.
4. Insert the seed into the opening you created. In order to ensure that every pot eventually gets a plant, even if one seed does not germinate or dies, we advise sowing two seeds each pot.
If you decide to plant 2 seeds per pot, you will need to thin them after the first set of leaves appear to 1 seedling per pot. At the soil line, trim or pinch out any surplus seedlings. Pulling it out could damage the surviving seedling’s roots, so avoid doing so.
5. Cover your seed with soil mixture after sowing. To remember what you planted when and how much of it, we advise labeling your containers with the variety and the date.
6. Lightly mist the seeds you covered. Use a watering can or hose with a diffuser attachment to let the water fall gently like rain. This will stop the water from washing the dirt away or compacting the soil too much.
Create the ideal circumstances for germination as you wait for your seedlings to appear. The two most critical variables are water and temperature. Your soil should always be damp, but not drenched. The ideal soil temperature is between 55 and 70 °F. You can start your seeds outside if the weather permits. A greenhouse or your home must be used to start them otherwise. Provide protection from birds, snails, and slugs if beginning them outside.
You must give your seeds a decent source of light once they have sprouted. If you want to keep them inside, you can put them beside a window as long as the sun won’t make them too hot during the day. Sweet peas do not have an issue with cooler nighttime temperatures near a window. Another option is fluorescent lighting. However, for the intensity to be bright enough, plants should be placed between 6 and 12 inches from the lights.
7. If you started your seeds indoors, the seedlings must be hardened off before being transplanted into your garden. Hardening off is the process of gradually exposing your plants to the elements they will experience outside, with temperature and direct sunlight being the most important factors. If you don’t, your seedlings can have transplant shock once they are planted in the garden.
When your plants have around 3–4 pairs of leaves, you can begin the hardening off procedure. Place your plants outside where they will receive morning sun in full force and afternoon shade. If you don’t have access to such a place, you will need to relocate your plants every day so that they are in the morning sun and out of the afternoon sun. Move them to a location where they will receive direct sun all day after about 3–4 days. You can move them into your garden in a few more days.
8. You can pinch or chop off the top of your seedlings when they have 3–4 pairs of leaves, leaving 2-3 pairs of leaves. Your cut should be made just above two leaves. By encouraging lateral branching, pinching helps you grow plants that are fuller.
9. Since sweet peas require healthy, well-drained soil, add some aged manure or other finished compost into your garden bed before planting. Work the material into the soil and rake the bed to level it out.
To move your seedling, make a hole that is both deep and wide enough to accommodate the root ball.
10. Try to minimize root disturbance while transferring your sweet pea seedlings from their container. Try it. Put one hand over the top of the pot, the seedling in your fingers, and flip the pot over to grab the root ball. Using the other hand, gently touch the bottom of the container while squeezing the edges to release the soil and plant.
11. Insert your seedling into the resulting hole, then cover it with soil. It is crucial when transplanting sweet peas that the soil level remain the same as it was in the pot. The plants may become sickly, stunted, or even die if you bury too much of the stem.
12. Leave 5 to 6 feet between each transplant. Your mature sweet peas’ health depends on the proper spacing between plants. Additionally, it provides the roots of individual plants with enough room to forage for water and nutrients while also enhancing air circulation to help avoid disease.
13. Gently water in your seedlings as soon as you are done transplanting. In addition to giving the plant water, this settles the garden soil around the root ball to prevent huge air pockets from drying out the roots. Use a watering can or hose with a diffuser attachment to water your plants, which will make the water fall gently like rain instead of washing the dirt away or beating your tender seedlings.
Tall sweet peas require a sturdy support in order to ascend. Build one now so that it is there when your seedlings are prepared to begin climbing.
14. You must keep birds, snails, and slugs away from your sweet pea seedlings. In order to prevent these typical predators from discovering your sprouts and eating them before you even realize they are up, you should do this as soon as possible after sowing your seed.
Use netting for birds. We create our own support hoops out of polytube, which is a flexible, black plastic irrigation tube that is sold at most reputable garden centers. It should be cut into lengths that correspond to the width of your garden beds. To create arches over your sweet pea bed, bury the ends of the cut tubing in the ground. These arches should be covered with bird netting, which should be secured at all edges to prevent openings. Before your sweet peas grow large enough to attach themselves to the netting, remove it. We choose the product Sluggo for snails and slugs because it is safe for use on people, pets, and wildlife.
15. You might want to assist stray branches in locating their vertical support structure as your plants grow higher and begin to climb. Encourage them to cling to you gently. Branches of sweet peas quickly break.
16. We advise deadheading to prolong the blooming period of your sweet pea plants. This entails removing wasted flowers before they have an opportunity to use their energy to produce seeds rather than other blossoms. Deadheading is best done right when the bloom has peaked and is just starting to fade. Cut the entire flower stem off at all times.
17. The blossoming of this plant is fully complete. When you can see, the plants begin to slow down and eventually stop flowering altogether as the discarded blooms turn into seedpods. Whether you deadhead or not, all sweet pea plants eventually reach the end of their flowering season. However, you can extend the bloom time by removing spent blossoms.
18. The flowers are, of all, the whole reason of producing sweet peas. Don’t forget to frequently clip them and bring them inside. They create lovely bouquets with the most amazing scents. Additionally, the plant will produce more blossoms the more you cut!
How well do sweet peas transplant?
My seed-starting spreadsheet, which I create each year to instruct me on when and how to start seeds, indicated that I should have started my sweet peas on March 14. However, I was unable to wait any longer, so last weekend I went completely bonkers and planted them. (I’m a renegade who plants seeds, I tell you!)
Because you cannot locate good sweet pea plants at garden centers, if I could only produce one bloom from seed, it would be sweet peas. Additionally, if you can find them, they probably won’t transplant well because sweet peas simply don’t enjoy being treated that way. Sweet peas have a garden-like aroma to me. It has a unique aroma that you won’t be able to get anyplace else. To me, that justifies the small amount of work needed to grow them.
Based on this blog article, it appears like I started cultivating sweet peas for the first time in 2015, but I can’t believe it hasn’t been longer. Although I’ve always had fair to good success with them, I believe I’m improving every year.

Last year, I switched from growing them in 4-inch pots to root trainers, and I believe this was a good decision. Plants may grow excellent, lengthy roots thanks to root trainers, which are little but long cells. When it’s time to transplant them, it’s simple to take out the plug since they open up like a book. The concept is to covertly plant these picky plants—which dislike having their roots disturbed—into the ground.
I mark each and every root trainer cell before I plant anything. Every plant now has its own label with the name and the color on one side and the date I seeded it on the back because no matter how much I try to remember that one entire row is one sort of sweet pea, I always forget. When I’m ready to plant, it’s awful to have to go back to the plant packs and check to see what color a sweet pea is.
Each plant is given a label identifying the variety, color, and date of sowing.
The question is whether to soak or not to soak. Actually, there are several questions regarding how to handle sweet pea seeds. There are supporters of soaking, nicking (or roughing up with sandpaper), and pre-sprouting. I conducted a small experiment in which I cultivated plain old seeds, nicked seeds, and seeds that had been soaked, and the outcome was that none of that made a difference. Almost everything began to grow.
The reason I’ve never pre-sprouted my sweet peas in damp paper towel is that it just seems like an unnecessary step that I don’t want to bother with.
Therefore, I directly sow seeds—two per root trainer cell—into pre-wetted seed-starting mix that is about a half-inch deep. To stop a crust from forming on top of the soil as well, I always cover my seeds with vermiculite.
Sweet peas need a little warmth to germinate, so I cover the root trainers with plastic because the humidity dome won’t fit on them, place the plants on the germination heat pad, and cover everything with a towel to increase the temperature.
With the aid of root trainers, plants may easily stretch their roots during transplantation.
Once the majority of them have sprouted—there are usually a few laggards because sweet peas sprout incredibly erratically—I’ll move them under the grow lights and make sure to keep them moist (as you would with any seedlings).
I pinch them all down to two leaves when they reach approximately four leaves to encourage branching for great, bushy plants.
Sweet peas are one of the first items I take outside to the temporary greenhouse because they don’t tolerate a lot of heat. I hardly ever fertilize seedlings, but sweet peas appear to need a little boost exactly when I pinch them back, so I give them extremely diluted fish fertilizer to feed them.
It is possible to plant them pretty early. in fact, earlier than I usually do, and this year I’m going to make an extra effort to keep track of it. They should be moved as soon as you can because they can tolerate light frost and prefer to develop in the ground.
The sweet pea is unique. They prefer fertile soil (this is true of many vining plants). They dislike it when it gets too hot. Additionally, they dislike very acidic soils (not a problem in my garden). Generally speaking, I respond to these demands with something akin to “Suck it up, buttercup.” It is what it is. However, I will mix some manure or compost into the area where I will be planting them a week or two earlier if I’m feeling very kind.
Of course, I keep up with the watering and make sure they get enough sun. Here it doesn’t get hot enough to bother about protecting them from the afternoon sun, but in hotter places it can be useful. They do require a support for their vines. I prefer to train them up bamboo teepees instead of the 1-inch-holed plastic netting that some people use when supported by canes. The stems are tied in until they are between 18 inches and 2 feet tall, at which point they can stand on their own.
Beyond that, the only instruction I have for sweet peas is to pluck them repeatedly. Sweet peas just continue to grow if you don’t allow them to set seed, but if you allow even a few blossoms to set seed, the entire plant becomes grumpy as if it has decided that its task is complete. Therefore, when sweet peas are in bloom, I try to cut them every few days. This means that I have numerous little sweet pea bouquets all over my home. And you won’t hear me whine about it.
