CULTURE REPORT Growers now have two red choices in the compact varieties. 'Princettia Pure Red' is a more vibrant red with red cyathia. The current 'Princettia Red is more cranberry in tone. 'Princettia Queen Pink' has caught on for growers who like the vibrant color but would like a larger size. Three new Queen-sized beauties are Rose Punch, Hot Pink and Shell Pink. PRINCETTIA PRODUCTION Compared to traditional poinsettias, Princettia is easier to grow with less height, disease and pest management. It's most applicable for 4- to 6.5-inch pot production and 2-inch minis, along with bowls and pans. Princettia Queen is recommended for 6.5- to 8-inch pots. Timing schedule is similar to poinsettia. Varieties have a stronger root system that establishes quickly. Princettia also has a long sales window and is easily timed, being photoperiod responsive. GROWING ON Liners should be potted within 2 days of receiving and the plug should be placed at the same level as the growing media. Avoid stem contact with the soil for best results. Growing media should have a pH of 5.8-6.3 and a target soil EC of 1.5. High porosity is essential (75%-85%) for pore space. This creates space for air, water and oxygen. A starter EC of 1.5-2.0 is desirable.
