Tech Tips: 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.

Tech Tips: For earliest flowering, provide long days, high light levels, and warm temperatures. Preventive fungicide applications for powdery mildew are recommended, especially in high humidity environments. Palladium ® , Micora ® and Segovis ® fungicides have all been effective at suppressing pathogens. Insecticides, such as Avid ® , Mainspring ® and Flagship ® , are effective.

HB | 4 ppp | 10–11 weeks 2 gal. HB | 5 ppp | 10–11 weeks Tech Tips: Scentropia Heliotrope has a mediuM–Vigorous habit and typically requires some plant growth regulator (PGR) applications to keep plants compact, especially under tight spacing. Late B-Nine ® WSG sprays can delay flowering. Avoid severe drying out of the media. The beautiful purple-blue flowers have a sweet scent.

Tech Tips: The keys to success are to avoid water and heat stress when the plants mature. Scout for thrips regularly and thrips-vectored Tospoviruses. Check media EC periodically to avoid high salt levels. Moderate light levels and warm temperatures provide the largest flower.

Tech Tips: Sonics New Guinea Impatiens generally do not need any pinching. The keys to success are to avoid water and heat stress when the plants mature. Scout for thrips regularly and thrips-vectored Tospoviruses. Check media EC periodically to avoid high salt levels. Moderate light levels and warm temperatures provide the largest flower.
