A B-Nine 2,000-3,500 ppm and Cycocel 1,000- 1,500 ppm tank mix(S) will help control height.
Whitefly, fungus gnats, thrips
Botrytis, Pythium, Rhizoctonia
Regularly allow the media to dry between waterings, particularly during cool periods. Prefers warm conditions to ensure early flowering. Regularly allow the media to dry moderately between waterings, especially in cool periods. Proper pinching and moderate feeding will improve habit and flowering. Pinch two weeks after transplant. Plants should dry between watering. PGR is recommended for regions with high light levels and high tempratures. Regularly allow the media to dry between waterings, particularly during cool periods. Prefers warm conditions to ensure early flowering. Scaevola prefers a well-drained soil. Allow the media to dry between waterings. Night temperatures lower than recommended will significantly slow the crop and lead to problems with root rot. Moderate light levels produce more colorful foliage. Pinch early to shape. Feed regularly to maintain growth. Using fertilizers with low phosphorus during early stages will aid in minimizing stretching. Alternative finishing for Southern Regions would be a long cycle crop similar to those of dipladenia. Pinch two weeks after transplant and use a trellis for the plant to climb up. Thunbergia is a warm-season crop that prefers night temperatures above 60°F (15°C). Pinch regularly to shape. Torenia is a warm-season crop that prefers night temperatures above 60°F (16°C). Pinch regularly to shape. Regularly allow plants to dry between irrigation.

Generally not needed. Bonzi(D) at 1-3 ppm two to four weeks after transplant will tone finished growth when grown warm in the greenhouse. Cool night temperature during production cycle promotes tight habits. Responsive to a B-Nine 2,500-3,500 ppm/ Cycocel 750-1,000 ppm tank mix(S) and Florel(S) 250-300 ppm to control growth and improve plant habit.
