Effect of Time of Pruning on Greenhouse Roses
This report covers the third study in a series of three rose pruning experiments. Previous results were published in CFGA Bulletin 273 and 282. The first compared gradual pruning to complete pruning cutback. The second, Bulletin 282, investigated the effect on production of pruning roses on June 15, July 1, and July 15. This analysis investigates pruning dates of July 15, August 1, and August 15.
