Kunzea (Myrtaceae). Starting at 70 was better than starting at 40. The result that K. vestita required GA-3 or light while K. Baxteri did not requires checking. K. baxteri germ. 70L(60% in 4-6 d), 70D(46% in 6-8 d), 70D GA-3(60% in 6-10 d), 40(18% in 7-12w )-70(1%), and 50% in October from seed placed outdoors in late September.

Protocol 2

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

Start around March 26, 2027 for a May 3 last frost.

  1. Gibberellic acid soak

  2. Sow and cover

    Temperature: 70°F 21°C Light: dark

Protocol 3

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

Sow around September 2027 — a date the source gives, not one counted back from a May 3 last frost. Too late for spring 2027 — that needed starting on September 2026.

  1. Sow outdoors and leave it

    Put out in late September; up in October.

No stated waiting before sowing. Germination time not stated; 21 days assumed.

50% germination.

Half the packet, with no equipment at all.

This source doesn't state how long.

Protocol 4

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

Start around March 28, 2027 for a May 3 last frost.

  1. Sow and cover

    Temperature: 70°F 21°C Light: dark

No stated waiting before sowing. Then 8 days to germinate.

46% germination in 6–8 days.

It does not need light, unlike K. vestita. Deno says that difference needs checking.
