Many of you know this already. Janis Ruksans grows bulbs in Latvia, where even ordinary winters are very cold. His monograph Crocuses (Timber Press, 2010) includes photos of a hoop house with long aisles of waist-high beds made of bricks and filled with coarse sand or gravel. In Plate 8, he and an assistant are removing oblong pads of winter insulation from a bed in which a few sprouts are up. The pads look to be yellow fiberglass, about 4 feet (1.5 m) long, half as wide and a couple of inches (~ 7 cm) deep. It might take some doing to adapt this ploy for beds that are mounded, not flat, and greenhouses that are open-sided, not closed. I have occasionally enclosed a chunk of pink fiberglass in a plastic garbage bag and placed it over a tender plant outdoors, holding it down with rocks.
