At the University of Florida trials, a section focuses on some of the component plants often used in mixed containers. For 2002, we selected Vinca major and Helichrysum. The idea was to come up with basic production...
Growing annual and perennial flowers for cutting during the summer is becoming a popular way for greenhouse operators to bridge the spring bedding plant and holiday potted crop seasons. In many respects, outdoor flower crops...
Tulips are a good example of a flower bulb crop that can be adapted to hydroponic culture. In Holland, approximately 30-35 percent of the cut tulip crop is forced hydroponically, and we have been evaluating this production...
Water is becoming a very precious, and increasingly scarce, commodity — both in and outside the horticultural community. The view of water as cheap and plentiful has slowly begun to change — just ask growers in California,...
The most important primula species in production today include English primrose or acaulis primula (Primula vulgaris, synonym P. acaulis), polyanthus, polyantha primrose or hybrid primrose (P. xpolyantha), fairy primrose or...
From droughts and fires to unusually cool temperatures on the side of nature, to recession, corporate earnings fraud and the impending threat of terrorism on the side of man, circumstances this year may have been enough to...

We saw it this spring at the California Pack Trials, this summer at the Ohio Florists’ Association’s Short Course and now in the pages of GPN. And it’s not only the British. Germans, Dutch, Japanese, French...
Though seldom part of the original design, irrigation systems need filtration to rid contaminants from the lines. This ensures that plants are being watered properly and reduces the frequency of irrigation system maintenance...
