The Q&A Archives: Planting Four O'Clocks in Zone 6 (OH)

Question: I'm hoping to plant some four o'clocks from seed. I'm wondering: What time of year should I plant the seed? How far apart should the seeds be planted? What germination rate can I expect? To what extent will they "winter over" here in central Ohio? Thanks much. Janet Boyd Marysville, OH

Answer: You will be able to plant seeds once the ground has started to warm up and has dried out, probably mid-April. Four o'clocks should be planted 12"-15" apart and should germinate outside in 7-15 days depending on weather conditions. I would't expect them to "winter over" in zone 6.
