Chrysanthemum x morifolium 'White'

Chrysanthemum x morifolium 'White'

 

Harvest flowers when at least 50% of the flowers are completely open. Harvesting too immature generally results in diseased buds. Postharvest flower life was the same regardless of the relative humidity the plants were exposed to (70-93%) during production. However, plants grown under high relative humidity (90-95%) produced more dry weight than when grown under lower humidity (55-60%). Application of a proper growing media wetting agent just prior to harvest and sale can delay postharvest wilting time by about 3-4 days. Application of the growth retardant B-Nine at 2500 ppm 2 weeks after the initiation of short days can increase postharvest flower life. If growing media temperatures reach 104F or higher (which can happen if sunlight reaches dark colored pots), the plants can be predisposed to severe Phytophthora infection.
