What temperature can sweet peas survive?
In most climates, heat is what shuts them down. Once you start seeing hot days and warm nights, the end may be near for a sweet pea. Plants can tolerate warm days if they cool down to 45-50 f at night, but many warm climate growers simply can’t offer that. If you’re growing in a hot climate, you may want to consider growing your sweet peas in containers instead of pots.
This will allow you to control the temperature of your growing area and keep your plants from getting too hot or too cold. You’ll also be able to keep the humidity in your grow area as low as possible, which will help prevent mold and mildew from forming on your plant.
Do sweet peas need full sun or shade?
Peas enjoy full sun in the northern half of the US. In the South, they can benefit from afternoon shade. They like cool roots so they are planted as early as possible in the spring. Newly planted pea plants will not be affected by a light frost. Peas can be grown in a variety of soil types, including clay, loam, sand, silt, and peat.
The soil should be moist but not soggy, with a pH of between 6.5 and 7.0. Plant peas in well-drained soil that is not too wet or too dry. If the soil is too moist, the plants may not be able to take up enough water to grow well. Pea roots will grow faster if they have plenty of water, but they will also be more susceptible to root rot and other diseases.

Do sweet peas come back every year?
After setting seed, sweet peas only live for one year. They are easy to grow from seed, so don’t let this stop you.

Do sweet peas need protecting from birds?
The newly sown seeds will always need protection from birds and mice, so, from the outset cover the seed beds with netting and set traps for the mice. Birds will ruin a crop if young pea plants are allowed to grow unfettered. Once the seeds have been planted, they need to be watered regularly to ensure that they do not dry out.
If the soil is too dry, the plants will not be able to take up water and will die. To prevent this from happening, it is best to water the plant in the morning before the sun goes down, and then again at night when the temperature is cooler. This will help to keep the roots moist and prevent them from drying out too quickly.
Can you plant sweet peas in pots?
