According to Sallie from Sal's Old Timey Feed & Seed, sugar snap peas love cool consistent weather which is most likely October to November and again February to March. She recommends planting them in pots, two seeds to a hole the depth of the size of the seed. Peas get their nutrients from the air, so aside from adding some good compost to the pot before planting, don't worry about fertilizing these plants. This "easy-peasy" veggie is one your students will love!
