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 propagated annuals to quantify how temperature and daily light integral (DLI) influence flowering time and plant quality. In the 11th article of this series, we present crop timing and scheduling information on angelonia (Angelonia angustifolia) and browallia (Browallia speciosa), and then use that information with Virtual Grower to estimate greenhouse heating costs at different locations, growing temperatures and finish dates.
