Tech Tips: Sonic 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.

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. Apply 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. Subdue Maxx ® , Mural ® , Micora ® , and Segovis ® fungicides can be used in a rotation program to control the common disease problems of Impatiens.
