Management:
- Apply nitrogen to soil at planting; do not over-fertilize.
- Plasticulture: Begin fertigation when blooms appear (approximately April 1). Submit foliar analysis samples between March 15 and April 15. Matted row: If leaves show deficiency symptoms, make a light nitrogen application in August. Apply nitrogen at renovation. Submit foliar analysis samples between July 15 and August 15.
