Tech Tips: Stick unrooted cuttings immediately to reduce bottom leaf yellowing and drop that can occur if cuttings are held for too long. Euphorbia is very sensitive to ethylene damage during shipping. Euphoric is a slow starter both in propagation and finish, but grows quickly when established and growing under warm temperatures. High light and warm temperatures will improve plant quality and reduce root diseases. If grown too cold and wet, fungal root can develop. Plants can be trimmed to shape at any point during production. Bonzi ® drenches work well to control growth mid to late in the production cycle.

Provide relatively high light levels and warm temperatures early on to establish the crop. Early Florel ® sprays are key in making well-branched, quality plants. Watch for Botrytis under tight spacing and in combination plantings, especially when overhead irrigating. Monitor the media and try to keep the pH between 5.5-5.9 to avoid iron deficiency (tip chlorosis).

Tech Tips: Caliente geraniums are moderately vigorous and usually require regular PGR applications, especially under warm growing conditions. Know the varieties since some are more vigorous than others. Provide relatively high light levels and warm temperatures early on to establish the plant and to allow it to respond adequately to PGRs. Early Florel ® sprays are key to making well-branched, quality plants. Watch for Botrytis under tight spacing and in combination plantings, especially when overhead irrigating. Monitor the media and try to keep the pH around 6.0. Too high of a pH can lead to iron chlorosis and leaf tip yellowing.

Tech Tips: Calliope Large geraniums are vigorous growers and usually require regular PGR applications, especially under warm growing conditions. Provide relatively high light levels and warm temperatures early on to establish the plant and to allow it to respond adequately to PGRs. Early Florel ® sprays are key to making well-branched, quality plants. Watch for Botrytis under tight spacing and in combination plantings, especially when overhead irrigating. Monitor the media and try to keep the pH around 6.0 to avoid iron/manganese toxicity.
