‘Zahara Coral Rose’ and ‘Zahara Yellow’ are two bright colors in this heat-loving series. Superior disease tolerance makes Zahara an excellent choice in the landscape. These varieties have very low water needs and perform well in sunny, hot and dry conditions.
Zahara can be produced in 306 premium packs, 1801s, 4-inch pots or similar-size containers. Use a well-drained, disease-free media with a pH of 5.5-6.2 and a medium initial nutrient charge. Maintain temperature at 65-70° F days and 60-65° F nights. Keep light levels as high as possible while maintaining appropriate temperatures.
Starting one week after transplant, apply fertilizer at 175- to 225-ppm nitrogen using predominantly nitrate-form fertilizer with low phosphorous. Maintain optimal media moisture (not too wet or too dry). Avoid overhead irrigation. Irrigation should take place during times when foliage will dry quickly, to prevent any disease incidence.
Avoid high humidity and condensation in the greenhouse, as these conditions are favorable for Botrytis and powdery mildew incidence.
