Perennials can be a challenge to grow commercially, if for no other reason than there is so much variability between crops. Paul Pilon’s comprehensive book covers all aspects of producing perennial crops—propagation, fertility, media, pest and disease management, weed control, height control, and overwintering. And, of course, a large section is devoted to forcing perennials into bloom to maximize sell-through at retail. Perennial Solutions presents specific production guidelines for thirty popular crops, including Aster, Delphinium, Hemerocallis, Hosta, Rudbeckia, and ornamental grasses. Detailed tables also offer specific recommendations for using plant growth regulators (PGRs), herbicides, forcing schedules, and more.
