How To Stop Sweet Peas From Growing Too Tall

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.

would make it more challenging for them to hold on and climb up. To resolve this, one solution is to use tiny nails (or

Grow Peas Up A Trellis

To secure the pea plants to the trellis, use twine much like you would for a fence. However, if the trellis is inclined, the pea plants might be okay growing on their own.

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!

Do you trim sweet peas back?

I have a beautiful sweet pea vine that has grown up the chain link fence and is covered in many pink and white blossoms. What maintenance should I give it over the winter? Must the vine be removed from the fence?

Although there are annual forms, perennial sweet peas are hardy in zones 4 to 8 and require little assistance to survive the winter in these regions. To boost hardiness, leave healthy plants standing over the winter. Before the plants start to grow, prune them back to the ground in late winter or early spring. In the fall, cut back sickly sweet pea plants to the ground. To lessen the chance of more disease issues, throw away the leaves and stems of sick plants rather than composting them.

Do you remove the peas’ tops with a pin?

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.

What height do sweet peas reach?

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 are sweet peas trellised?

  • 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.

Should sweet peas be pinched out?

Although it is not necessary to pinch out sweet peas, many gardeners do so in order to maintain the plants short and bushy. Some people decide to pinch back sweet peas to encourage the development of many bloom buds. Remember that sweet peas are climbing plants with a height range of 6 to 9 feet. Choose a shrub kind of sweet peas and prepare to pinch it back if you know you want shorter sweet peas.

By rerouting the plant’s resources, pinching operates. A sweet pea plant will make a concerted effort to grow tall toward the sun and absorb as much light as it can if left to its own devices. The plant switches to its backup tactic, which entails sprouting more stems, when the stem tip is removed. In this manner, it continues to produce a large number of leaves that can absorb sunlight.

Before being pinched back, sweet peas should be allowed to reach a height of at least 6 inches, according to the Old Farmer’s Almanac. Pinch the top of the core stem slightly above a leaf node with your fingertips to remove it. Attempt to cut cleanly.

Can lanky seedlings be buried further?

Turn the heat mat down or off if your seedlings appear to be getting lanky when you are using a seedling heat mat to start seeds inside. Warmth can stimulate seedlings to grow more quickly while also accelerating seed germination, which is fantastic. Let’s not encourage seedlings to grow even taller when they already appear to be on the lanky side. Naturally, this suggestion is in addition to greater lighting.

These seedling heat mats with an integrated thermostat control and temperature probe are something we personally adore using. We programmed our heat mats to activate only when the soil temperature falls below 65-70F after germination. In the winter and early spring, when it may get pretty chilly at night but also extremely warm during the day, this keeps our heat-loving summer crop seedlings (tomatoes, peppers, basil, flowers, etc.) happy in our greenhouse. The similar setup works well for growing seedlings indoors, in a garage, or anywhere else.

(3) Restart

Please bear with me on this. I’m not referring about beginning a fresh batch of seeds after your zone’s seed-starting season is already underway by several weeks or even months. However, starting fresh may be preferable to fussing over leggy seedlings for the remainder of the season if you have enough of seeds and things are already looking sluggish a few days after germination.

As an illustration, the other day I began a couple 6-packs of bok choy seeds in a dark spare room on a heat mat. As soon as they sprouted, I was going to move them to the greenhouse (and under a grow light) and check on them periodically. Well, I neglected to check on them for more than a day, they grew, and they already appeared to be much too tall for my taste. In order to use the leggy seedlings as the “poor example” for this piece, I simply started more bok choy seeds.

4) Strengthen them.

You may very well be able to sow your seedlings even if they are lanky! But first, they must be considerably fortified in advance. They won’t be strong enough to plant outside for a while. Additionally, young, leggy seedlings are typically too delicate to bury deeper in soil without the risk of the stems becoming rotten.

Within a few weeks of sprouting, be cautious to thin your seedlings to just one sprout per cell or container. Thinning lessens competition for nutrients, available area, light, and water, and enhances airflow. Instead than yanking and plucking out undesired sprouts, I always advise cutting them off. The following three methods can help you transform your leggy seedlings from tiny to mighty:

Add movement

Introduce a gentle wind using an oscillating fan to fortify seedlings. Turn it on just loud enough to cause some light shaking and movement, but not too loud. Leggy seedlings benefit from movement by developing stronger, more durable stems. Similar results can be obtained by tickling seedlings with your hands. A fan, however, has numerous advantages! Additionally, damping off and fungus are avoided by enough airflow. Whether or not indoor seedlings are leggy, I always suggest using a fan.

Use mild fertilizer and “water from below

The act of feeding lanky seedlings is another technique to improve their health! You can start feeding seedlings with a very mild liquid fertilizer once they have grown their first pair or two of real leaves (the ones that appear after the first two, which are frequently heart-shaped). Since they do not require or care for fertilizer much younger than that, the seedlings should be at least a few weeks old at this time.

Seaweed extract is what we prefer to feed our seedlings, while fish emulsion is also a common option. Whatever you choose, make sure to dilute it according to the bottle’s directions. The lower tray that the seedling containers are sitting in should then be filled with the liquid fertilizer/water. Whatever the soil need will be absorbed from the bottom. We always advise watering seedlings in that manner, especially the lanky ones. Pouring water in from the top doesn’t give evenly distributed moisture and carries the risk of tipping them over. By encouraging their roots to develop deeply when you water from below, you can grow stronger plants.

Finally, before moving leggy seedlings outside, always harden them off. The process of gradually exposing seedlings that were grown indoors to the environment is known as “hardening off.” This typically entails moving the seedlings outside daily for a week, initially placing them in the shadow for a short period of time before progressively exposing them to more and more direct sunshine. This strengthens the seedlings and better equips them to withstand difficulties like wind, rain, hot sun, or low temperatures. Instructions for hardening off in detail can be found here.

Can you bury leggy seedlings deeper in the soil?

In general, you can put leggy seedlings farther into the ground to help make up for their excessively long stems! When they are still extremely young and sensitive, resist the urge to plant them deeper right immediately. When buried in wet soil, weak, thin, and small stems are susceptible to decay. After completing the above-described procedures to strengthen and/or harden off the lanky seedlings, wait at least a few weeks.

You should be able to bury a piece of the lanky seedling stem once the stems are stronger and more resilient, either by potting them up or moving them outside. Or you could try both! For instance, we use four-seedling pots to begin our tomato plants. The seedlings are then potted up into bigger 8 nursery pots after about a month, and the stem is buried by a few inches at that time. We can bury the stem a few more inches if necessary when we transplant the plants into the garden.
