Plant Select® Greenhouse Media, Fertilizer and Plant Growth Regulator Study

This research is continuing some previous research conducted with just media and fertilizer on certain stock plants that are difficult to get adequate number of cuttings and a high percentage of rooting. This experiment will research Verbascum x ‘Letitia’ being grown in two different media, two fertilizers at two different rates and include one plant growth regulator. We will utilize these  findings from previous experiments and incorporate them into the new study to further fine tune production and propagation protocols. Experiment will be repeated twice in 2021.
