|This High Flying Combo combines ‘Acrobat Orchid’ snapdragon, ‘Gumdrop Cherry Blossom’ begonia and ‘Avalanche Rose’ petunia.
By Green Fuse Botanicals
Green Fuse Botanicals has put together a combination featuring ‘Acrobat Orchid,’ one of its new vegetative snapdragons, a vegetative ‘Gumdrop Cherry Blossom’ begonia and Benary Seed’s ‘Avalanche Rose’ F1 seed petunia.
The new Acrobat snapdragon series has a trailing habit, making it well suited for hanging baskets. Plants are well-branched, produce large flowers and flower profusely. The plants reach 4-6 inches tall and have good mildew and Botrytis resistance.
Gumdrop begonias are versatile and easy to produce in any size container. They grow 8-16 inches tall, have a full rounded habit and are covered with large, double flowers. They prefer partial shade and moist well-drained growing media.
The trailing Avalanche petunia series is significantly earlier to bloom than other series. All 10 colors in the series are uniform and reach 4-6 inches tall.
A 12-inch hanging basket is ready five weeks after transplanting 4-inch pots and plugs.

|Plant ‘Acrobat Orchid’ cuttings in a well-drained growing medium with a pH of 5.5-5.9 and electrical conductivity of 0.8-1.2. Plants should receive 150 parts per million nitrogen from a well-balanced fertilizer at every irrigation. Pinch plants twice while in 4-inch pots. Plants do not require any growth regulators and no supplemental lighting.
Stick ‘Gumdrop Cherry Blossom’ begonia cuttings in a well-drained commercial growing mix with a pH of 5.5-6.2 and electrical conductivity of 0.8-1.2. Maintain temperatures at 65°F-72°F initially to promote growth. Plant growth is very much dependent on temperatures. Gumdrops are self-branching and should not require a pinch. Use a balanced fertilizer at 100-150 ppm nitrogen in a continuous feed program. Water thoroughly and let the growing medium dry between irrigations. Grow plants on drier side for control of water mold diseases.
The best growth regulator for begonias is monitoring the amount of water applied. Excessive water stress reduces flowering. Cycocel at 750-1,500 ppm will control height.
Extremely low light conditions cause weak, spindly growth. Excessive light during propagation causes leaf cupping and dark bronzing.
Aphids and thrips are the most common insect pests. To minimize problems with Pythium and Phytophthora, allow the medium to dry between waterings. Drench regularly with preventive fungicides to control root diseases. Good air circulation and keeping the foliage dry are the keys to reducing the pressures of Botrytis. Extremely high light conditions and excessive drying damage the leaves during propagation.
Sow ‘Avalanche Rose’ into 280-cell plug trays containing a commercial growing mix with a pH of 5.8 and electrical conductivity of 1.0. Maintain a day temperature of 73°F and night temperature of 65°F. Plants can be transplanted into 32-cell trays after five to six weeks. To control growth in the flat, 1,200 ppm of B-Nine can be applied twice as a spray. Apply 150 ppm nitrogen from a balanced fertilizer at every irrigation.
