| Grams per 1000 seeds: | 1.14943 Gram |
| Seeds per Gram (does not correspond to the number of plants!): |
870 |
| Gram to get 1000 plants (if sown directly into pots etc. you will need a larger quantity): |
5 Gram |
| Sowing Rates/Trays: | 3 - 4 per cell |
| Plug tray recommended size(s): | 72 / 128 |
| Sowing Direction: |
(16) See 15 with the exception of germination being slower and more irregular. This poses no problems. (15) Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C [68°F]. Seeds must be covered thinly. Do not cover very small seeds, but tightly press into the earth. Keep in cooler conditions after germination occurs.
|
| 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): | 1-2 plugs per 11/12 cm (4 1/2") |
| 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: | This species is not a suitable candidate for forcing. |
| Fertilizer: | Medium (150-200 ppm) |
