The correct time of year to plant sugar-snap peas is approximately four to six weeks prior to the final spring frost. The seeds should be planted in fertilized, mulched beds. It is important to test the soil to ensure a temperature of at least 45 degrees Farhenheit prior to planting.
Sugar-snap peas thrive in moist soil that is lightly fertilized and properly drained. Additional mulch consisting of grass or compost should be applied to the pea soil when the plants reach six inches in height, as this helps to prevent weed growth and allows the soil to retain optimal moisture. Watering the pea plants during the morning hours can help prevent plant fungus.
