Tulips grown in high tunnels flowered three weeks earlier than those grown outside, potentially extending the season for New York growers. That’s just one of the findings you can read about in Chris Wien’s 2010 Cut Flower Cultural Practices Studies and Variety Trials.
Wien also studied the effects of delayed transplanting, pinching larkspur, the effects of daylength on sunflowers and rudbeckia and more. Trials also analyzed performance of varieties of amaranth, celosia, aster, Bells of Ireland, campanula, dianthus, gomphrena, ornamental kale/cabbage, lisianthus, marigold, scabiosa and snapdragon.
