Difficulty High Rated by us, not by the source.

Start around February 22, 2027 for a May 3 last frost.

  1. Sow and cover

    Temperature: 70°F 21°C Light: either

No stated waiting before sowing. Then 42 days to germinate.

Vaccinlum (Ericaceae). V. nummularia germ. 20% in 4-6 w in 70L or 70D and 40-70(none).

Protocol 2

DerivedN. C. Deno, 1993

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

    Deno gives no length for this period; three months is his standard cycle.

  2. Warm moist stratification

    Temperature: 70°F 21°C

    Nothing.

about 3 months from start to step 2. Germination happens during step 2.

0% germination.

Nothing after a cold period. Do not chill this one.

This source doesn't state how long step 2 lasts.
