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.
Must I remove the sweet pea seedlings’ pincers?
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.
Watch Monty as he demonstrates how to put out store-bought plants while planting sweet peas. Find out the advantages of giving them a nice drink after planting as well as why it is best to plant them out just once the soil has warmed up:
How often do I need to pinch out sweet peas?
- 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.
Why are the seedlings of my sweet peas leggy?
Lathyrus latifolius, or “everlasting sweet peas,” are perennial cottage garden plants that differ from the more common sweet pea. They grow back the following year after you chop them down in the fall. Sadly, they lack Lathyrus odoratus’ wonderful aroma.
They will do much better outside, but as they have been indoors thus far, they will require a little bit of shelter there until they harden off. They are too warm and aren’t getting enough light. Are there any cold greenhouses or cold frames you have that they may use?

Should I remove the tendrils of the sweet peas?
Concentrate your attention on the stem that is the strongest. As side shoots grow, they disperse the energy, which could lead to shorter stems and fewer flowers.
The sweet peas, which were planted outside in late April or early May, will begin to bloom in late May or early June. We continue to cut off side shoots and tendrils as they grow while checking on the plants twice a week. We’ve discovered that cutting the shoots instead than pinching them out by hand causes them to frequently regenerate. It might just be coincidence, but it’s faster nevertheless.
How can you aid sweet peas in growing?
Sweet peas climb by wrapping its tendrils around the support frame, however sweet pea support rings are useful for directing them.
As your plants begin to run off, keep an eye on them and continue to tie them in as they grow. Over the course of the entire growth season, you must perform this every 7 to 10 days. For straighter cut flower stems, encourage the plants to grow vertically up the frame.
Do sweet pea roots require training?
Sweet pea seeds frequently have a tough seed coat, which makes germination more challenging. Simply set the seeds on wet kitchen paper in an airtight container in a warm area to soften the seed covering. They can be seeded as soon as they start to sprout or bulge.
You will require root trainers, which are long, thin pots, to seed the sweet peas. Visiroot 4 Deep Cell Kit from Gro-sure. Deep pots like this are ideal for sweet peas since they tend to establish long roots. Put seed compost, such as Gro-sure Seed & Cutting Compost, in the root trainer. Cover the seeds with compost after planting them about 2 cm deep.
Do you prune dwarf sweetpeas with a pinch?
For best results, sow indoors from January through March or from September through October, 1.5 cm (1/2″) deep, and 5 seeds per 12 cm (5″) pot of compost. Place in a chilly windowsill, cold frame, or greenhouse after well-watering. Ideal temperature is 15C (60F). Hold wet. Typically, seedlings emerge in 12 to 21 days. When two pairs of leaves have grown, pinch out the growing tip to promote bushy growth. Before placing young plants outside in well-drained soil from March to May, gradually acclimate them to outdoor circumstances (avoid frosts). Alternatively, you can easily put seeds outdoors in well-prepared, well-drained soil that has already been irrigated, 1.5 cm (1/2″) deep, in the area where they will bloom, between April and May. 30 cm apart, sow 2 seeds together (12″). Eliminate weaker seedlings so they can be transferred later. Autumn-sown seeds typically bloom early the following year. May to October for flowers. Regularly remove blossoms to extend the flowering season.
