Peas are rime - hardy , cool - time of year vegetables that can be grow in country where there is a long , cool grow time of year . pea can be classified as garden pea plant , tear pea or snow peas . Since peas are a coolheaded - season veg , they will be fine if expose to a abstemious frost , although a hard frost may damage the prime .
Step 1
Peas have splendid rime tolerance because the industrial plant ’s originate detail remain underground during the seedling stagecoach , between the seeded player and the soil Earth’s surface . If one of the acquire point is stamp out by frost , the plant ’s nodes become active and will send a unexampled shoot to the grunge surface . The pea plant will ripen afterwards than it would have if its independent shoot had n’t been killed , but it will not die .
Temperature
Young pea plant plant will develop at any temperature above 40 degrees Fahrenheit . idealistic temperatures for growth fall between 55 and 65 degree Fahrenheit . Purdue University notes that peas can withstand very coolheaded temperatures as coolheaded - season plants . They can put up temperature to 28 degree Fahrenheit in the seedling stage , for instance , although above - ground emergence may be affected at temperatures below 21 degree Fahrenheit . Very hardy varieties of peas can last temperatures as low as 14 degrees Fahrenheit with snow cover protection . As a cool - season works , peas are really damage more by high temperatures than by nerveless temperature .
Step 2
Blossom Damage
While the pea plant life can survive cool temperatures , the blossoms and pod of the pea plant plant may be damage by late spring frost . Once the plants have begun to blossom and produce yield , they are vulnerable . catch the weather condition forecast , and take guardianship to protect the plant if Robert Frost is foretell . Planting your pea plants late enough in the time of year will aid preclude this . Depending on the variety , industrial plant peas 70 to 90 days before the particular date of the average early backbreaking icing for your area . This should prevent plants from blooming while there is still the possibility of a hard frost .
Protection
Should a frost be predicted after your pea plant plant have blossom forth , take care to protect the plants from the frost . Shelter the pea plants with sheets or some other covering . A dusty frame or hoop greenhouse with a charge card roof will protect the plants during a heavy rime if necessary .
