Super Sonic growth can be controlled using sprays of Bonzi ® (1–3 ppm). Avoid late Bonzi ® sprays to prevent flower size reduction. Florel ® (300 ppm) can be used early on after transplant to delay flowering, but this should only be done for large baskets or pots where flower delay is desired.

Super Sonic ® White 70003754 M Tech Tips: Super Sonic New Guinea impatiens are relatively fast rooters. Unrooted cuttings are sensitive to chilling, so avoid storing cuttings<48 °F (9 °C). Super Sonics generally do not need any pinching. 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 most significant flower. V

Sidekick ™ Lime 70028150 M N/A Tech Tips: Stick unrooted cuttings immediately to prevent dehydration. Plants are chilling sensitive, so avoid storing cuttings<48 °F (9 °C). Sidekick is a moderately vigorous ipomoea that works in a range of pot sizes, including quarts and baskets. They are excellent in combo plantings. Watch for Aphids during finished production. Bonzi ® drenches work well anytime during production to control growth.
