GAILLARDIA aristata 'Amber Wheels'
Plant Description
Best Sowing Date (northern Hemisphere, Field condition): |
Anytime |
Sowing to Germination: | 2 - 3 weeks |
Germination to Transplant: | 4 - 8 weeks |
Transplanting to Potting: | 6 - 10 weeks |
Cutting back at Transplanting: | Cut back 1-2 times; once at transplanting; once again 4 weeks later to keep more compact. |
Container Size(s): | 1 plug per 8/9 cm (3 1/2") / 2-3 plugs per 15 cm (6") |
Vernalization: | There is no current research on vernalization but a prudent recommendation for any perennial would be 6-12 weeks (a few might need 15 weeks!) at an average daily temperature of 40°F (5°C). Exposure to cold may not be necessary for flowering but might improve quality. |
Forcing: | An obvious place to experiment - following vernalization - would be raising daytime temperatures to 60° - 65°F (15° - 17°C). Provide 16 hours of continuous lighting. During the short days of winter, provide a night interruption lighting of 4 hours between 10:00 p.m. and 2:00 a.m. |
Fertilizer: | Medium (150-200 ppm) |
