How-To Production: WonderFall Trailing Pansy

In recent years, advances in pansy breeding have brought a new class of pansies with trailing growth habits to market. These pansies have great sell-through at retail in spring and fall because of their unique spilling habit, floriferous growth and continuous flowering. The new WonderFall pansy series from Syngenta is an example of a trailing

Callused Geranium Cuttings: Tips For Successful Rooting

Growers are always looking for opportunities to improve production efficiency and reduce costs. One option is to use callused cuttings when producing vegetative geraniums. The key advantage of starting with callused instead of unrooted cuttings is that they can be directly stuck into the finish container without the need for an automated misting system. Additional

Ready Research Results: Daily Light Integral & Flowering Of Annuals

Daily light integral (DLI) refers to the cumulative amount of photosynthetic light that is received in one day. Determination of the DLI requires that light is measured repeatedly over time and then integrated. It cannot be determined instantaneously. DLI is expressed as moles of photons of light received per square meter per day (mol∙m¯²∙d¯¹), or

Energy-Efficient Annuals: Pentas & Verbena

Efficient production of bedding plants requires information on how temperature, photoperiod, and daily light integral (DLI) influence crop timing and flowering characteristics. During the past several years at Michigan State University (MSU), we have performed experiments with seed-propagated annuals to quantify how temperature and DLI influence flowering time and plant quality. In the 12th and

Energy-Efficient Annuals: Angelonia & Browallia

Scheduling annual bedding plants in flower for specific market dates is of increasing importance to greenhouse growers. Plants not in flower when planned or in flower too early can create greenhouse space challenges, delay shipping and reduce plant quality. During the past several years at Michigan State University (MSU), we have performed experiments with seed

Energy-Efficient Annuals: Dahlia & Osteospermum

Producing spring bedding plants in an energy-efficient manner requires information on how crops respond to average daily temperature and daily light integral (DLI) so bedding plants can be more precisely scheduled. At Michigan State University (MSU), we have performed experiments with numerous seed-propagated annuals to quantify how these environmental factors influence flowering time and plant

Energy-Efficient Annuals: Rudbeckia & Viola

Scheduling bedding plants in flower for exact market dates is challenging considering the diversity of crops produced. Rising energy costs and shrinking profit margins have made it important to improve scheduling and efficiency of crop production. At Michigan State University (MSU), we have performed experiments with many seed propagated annuals to quantify how temperature and

Energy-Efficient Annuals: Geraniums And Zinnias

Most bedding plants are produced in heated greenhouses from January through May, when high energy inputs can be required to maintain a desirable temperature. With shrinking profit margins and volatile energy prices, scheduling crops in an energy-efficient manner is increasingly desirable. At Michigan State University (MSU), we have performed experiments with many seed-propagated annuals to

Energy-Efficient Annuals: Petunias

Escalating fuel costs have made it important for greenhouse growers to improve production efficiency and schedule crops more efficiently. At Michigan State University (MSU), we have performed experiments with many seed-propagated annuals to quantify how temperature and daily light integral (DLI) influence flowering time and plant quality. In the sixth article of this series, we
