Growing Tips for Peas
- Soak pea seeds overnight before planting to speed germination in cool soil.
- Install a 4–6 foot trellis at planting time — peas climb from day one and produce more per square foot when supported.
- Sow every 2 weeks through early spring for a continuous 6-week harvest window.
- Plant a second crop 10–12 weeks before first fall frost for autumn harvests; shade cloth helps germination in warm soil.
