No PGR necessary. Pinch once for increased branching on smaller pots. Pinch 1 to 2 times for larger pot sizes.
General Pest and Disease practices as listed in notes. Whiteflies.
Early season production not recommended due to light quality and heat requirements. Can be grown in late summer and overwintered for spring sales OR grown in late spring for summer sales. The critical issue is daylength plants must have long days to grow and flower. ANY short days in production will cause the plants to rosette.
