Data is gathered from our Elburn, Ill., trials (Zone 5a) for a North American audience. Warm-climate growers: expect 1-2 weeks earlier finishing. Cool-climate growers: expect 1 week slower. Dates based on standard 288 plug size.

Notes/Pitfall Management
Primarily grown as an annual. One or two pinches/trims can help manage container size. B9 is also beneficial.
