Tech Tips: Tango Zonal Geranium is relatively compact and should not require repeated PGR applications. Provide relatively high light levels and warm temperatures early on to establish the plant and to allow it to respond adequately to plant growth regulators (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.

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: Silhouette Impatiens generally do not need any pinching if cuttings are compact and well-branched. Florel ® can be used early but is usually not needed. Keys to success are to avoid water and heat stress when the plants mature. A Bonzi ® drench during mid-late season to keep growth under control. Scout for thrips regularly and thrips-vectored Tospoviruses. Check media EC periodically to avoid high salt levels.
