Early Spring through Fall Finish. Standard PPP.
Repeated lower level PGRs are better than high rates less frequently. Paclobutrazol drench at 2–3 ppm, or tank mix of 5000 ppm daminozide + 1000 ppm chlormequat chloride spray, 1–2 weeks after pinching; 2–3 ppm drench at first sign of visible buds; 2 ppm drench when flowers start cracking color to hold for finish. Southern growers will need to use slightly higher rates (+- 1-2 ppm).
Hard pinch required to improve branching and control vigor.
For single stem plants – no pinch needed
Treat with a preventative broad spectrum fungicidal drench at 1-2 weeks after transplant.
Good air circulation, control of humidity, and good sanitation practices are critical. Good water management practices are critical to healthy plant growth.
