Troubleshooting
Garden Pea problems — and how to fix them
Garden Pea (Pisum sativum 'Kelvedon Wonder') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Mice eating seed
Sown seed is dug up and eaten before germinating; start in guttering or modules under cover, or protect direct sowings.
Powdery mildew
White coating in warm, dry late summer; this cultivar resists it, but improve airflow and water at the base to slow spread.
Pea moth
Maggots inside pods from mid-season flowering; early sowings often crop before peak moth activity, reducing damage.
Poor pod fill
Dry soil at flowering gives flat, half-empty pods; keep moisture steady from flowering through harvest.
Prevent garden pea problems before they start
Most garden pea issues are care-mismatch, not bad luck. Dial in the basics:
