In Rhode Island: watch for
The pests that find snap peas here.
A middle-length season, about 200 frost-free days, means snap pea overlaps pea aphid for a stretch each summer. Check plants every week or two and treat early.
Clusters on the tender growing tips where new tendrils form.
Organic fix: Knock colonies loose with a firm blast from the hose before they build.
White powder on leaves after warm dry days and cool, dewy nights.
Organic fix: Grow resistant varieties and trellis so vines are not lying on each other.
Root rot
Seedlings stall and yellow from the bottom up, and a lifted plant shows soft brown roots instead of firm white ones.
Organic fix: Sow into a raised or well-drained bed, work compost into heavy ground, ease off the water, and move peas to fresh ground next year.
Your season math: Rhode Island gives snap peas about 200 frost-free days, and it needs roughly 62 days to a first harvest. That fits about 14 re-sown rounds across the season, so you can keep it coming instead of picking once.
