Start seeds indoors six weeks before last frost date.
Try to aim for a seed spacing of at least 2.60 feet (80.0 cm) and sow at a depth of around 0.78 inches (2.0 cm). Soil temperature should be kept higher than 12°C / 54°F to ensure good germination.By our calculations, you should look at sowing Dr. Wyche's Yellow about 42 days before your last frost date.
Transplant out when around 15cm (6 inches) high.
Plant to the first set of true leaves to promote strong root growth.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Dr. Wyche's Yellow is a tender plant.From SSE:
Given to SSE by the late Dr. John Wyche, one of SSE’s earliest members. Dr. Wyche used to own Cole Brothers Circus which overwintered in Hugo, Oklahoma. He fertilized his terraced mountain-top gardens with elephant manure and scattered lion and tiger waste to keep out deer and rabbits.
