As the first vegetative gomphrena on the market, Pinball stands apart with its strong mounding habit and vibrant color. Consumers will appreciate its landscape performance and heat and drought tolerance. The unique texture and continuous flowering make Pinball an excellent component plant for mixed containers.
Gomphrena is suited for production in many different sized containers and hanging baskets. Select a sterile, well-aerated mix with 5 to 15 percent porosity. Optimum pH range is 5.8 to 6.2, and maintain EC below 0.75.
Avoid excessive irrigation through production. Commence fertilizing two weeks after transplant with a complete, balanced fertilizer at 150- to 200-ppm nitrogen. A slow-release fertilizer is an option, especially for outdoor production where heavy summer rains are common. In addition, a slow release may provide improved performance for the consumer.
Establish the crop at an average daily temperature of 65° F. Once established, grow at 70 to 75° F days and 65° F nights. Provide good air circulation and a relative humidity below 70 percent to prevent Botrytis.
Bright light is ideal for this crop. For best results initially provide 3,500 to 5,000 foot-candles. Gomphrena will tolerate full sun conditions once established.
