Pre-treatment of smoke may be beneficial.

Some research has shown this species may responsive to smoke, although it is not critical for germination of this species it may be beneficial in reducing the number of days to germination and increasing germination rates. Smoke treatments available by clicking here.

  1. Sow 2-3mm deep.
  2. Water with fine mist spray to avoid disturbance of the seed.
  3. Place in a warm shaded or semi shaded position to avoid dying out.
  4. Keep warm & moist, avoid drying out or waterlogging the growing mix.
  5. Germination generally occurs in around 21 days in the right conditions but may take up to 90 days or longer depending on the conditions. 

General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
