New for 2013, the Happy Trails series is well branched and produces large, double flowers in vivid colors. Happy Trails was bred to deliver exceptional reduced day length sensitivity. Plants flower under short days (10-hour photoperiod) so you can sow up to two weeks earlier to sell earlier.
Use a well-drained, soilless medium with a pH of 5.5 to 6.2 and a medium initial nutrient charge. Maintain temperatures between 65 to 67° F nights and 68 to 76° F days. Flower buds may not develop or open if temperatures are too low. Maintain light levels as high as possible while maintaining recommended temperatures.
If transplanting plugs when the day length is shorter than 10 hours, provide long day conditions after transplanting. Day length extension to 12 to 13 hours can be used.
Do not overwater. Allow the media to dry thoroughly between watering. Plants can be allowed to wilt slightly after the roots reach the side of the container. Fertilize every other irrigation with 15-0-15 alternating with 20-10-20 at 150- to 150-ppm nitrogen.from PanAmerican Seed
