Uncovering Outdoor Bogs in Early Spring: Temperature Guidelines

An Ulster County, NY grower (90 mi north of NYC) has temperate CP bogs in full sun, 50/50 peat/sand, RO/rain water. Forecast: days 40s–50s°F, nights 20s–30s°F, possible snow. Asks when to uncover and how to protect from severe drops.

Guideline

If daytime temps stay above freezing consistently, uncover. Keep temporary cover handy. Snow is fine; clear cold nights below 25°F warrant covering. Late frosts can nip new growth (e.g., early May freeze damaged S. flava in Oregon).
