How do you grow sweet peas on a fence?

Last Updated: 8th April, 2020

22
Thin the sweet pea plants to one every 6 inches when the sprouts are 4 inches tall. Spread an inch layer of mulch around the base of the plants to keep the soil cool and moist. Train the vine up the fence. Sweet peas do not need tying to the fence since they will hang on to the fence with tendrils.

In this way, do Sweet peas need something to climb on?

Plant the vines about 6″ apart in a sunny location, ideally with protection from intense, afternoon sun. Unless you've selected a bush-type, your peas will need strings or a trellis of some kind. Peas use tendrils to climb. They can grasp anything that's a quarter-inch or less.

Furthermore, how often do you water sweet pea seeds? Sweet peas rarely need watering more than once a week, but you need to maintain even moisture throughout the growing season. They do not like hot weather, so water them regularly in the summer, but do it early in the day to prevent buds from dropping, yielding and fewer flowers, and to prevent plants from scorching.

Regarding this, should you soak sweet peas before planting?

Soak the seeds in water for 24 hours before sowing. This softens the seed coat and speeds up the sprouting process. While the seeds are soaking, fill your planting pots with good quality potting soil.

What month do sweet peas flower?

By early to mid summer, the fragrant flowers are in full bloom in the garden. Sweet peas are best planted directly into the garden bed, but in areas with a long, cold spring, you can start seeds indoors four to six weeks before the last frost date in your area.

What month do you plant sweet peas?

Sow your sweet peas seeds anytime from October until March, two seeds to a pot. You can sow your sweet pea seeds in March but growing sweet peas over winter will produce stronger, more robust plants.

Do Sweet peas come back every year?

Sweet peas (Lathyrus odoratus) only live for a year, dying after setting seed. But don't let this put you off as they are super easy to grow from seed. Perennial species such as Lathyrus latifolius come back year after year, but mostly lack fragrance and there are fewer to choose from.

How do you train sweet peas on a trellis?

It doesn't take long for sweet peas to climb, so place your supports at planting time. To train your sweet peas to grow on a support, simply point them in the right direction when they're about 4 to 5 inches long. Once they reach the bottom of their vertical support, they will climb on their own effortlessly.

How do you take care of sweet pea bushes?

Sweet pea shrubs survive without a lot of supplemental irrigation, but they look best if you water them regularly. Remember that those grown in containers need water more often than those grown in the ground. Since they bloom year round, they appreciate a little general purpose fertilizer in both spring and fall.

Why are my sweet peas turning yellow at the bottom?

Yellow leaves on the bottom of the plant
Leaves starting to go yellow on the bottom of the plant is usually caused by over-watering, or by watering from a cold hosepipe. It can also be caused by the compost being used being too rich and burning the roots of the plants.

Do Sweet peas need a trellis?

Except for the bush types, sweet peas are real climbers. Give them at least 6 feet of good support. Some varieties may climb to 9 or 10 feet. If you don't have a fence or trellis, provide brush or chicken wire or bushy, stubbly twigs that they can cling to.

Should I soak sweet pea seeds?

Many people recommend soaking sweet pea seeds overnight before sowing to help them germinate. This is because some varieties have a hard outer shell. However, others suggest that soaking may lead to weaker plants. Generally, sweet peas should germinate fine without any treatment.

Start sweet peas now indoors by sowing one seed in each 2-inch or larger plastic pot filled with sterilized potting soil or a peat pot. Once the seeds have sprouted (most within two weeks), remove the pots from the heat source. Place them in a bright window or another spot where they'll get plenty of light.

How many sweet peas are in a cane?

I like a minimum of 8 canes per variety and so I plant 4 plants on every other cane. The empty cane is left for the spring sown peas, which are sown as soon as I've finished planting out, and go out themselves around early May.
