- Water with fine mist spray to avoid disturbance of the seed.
- Place in a warm shaded or semi shaded position to avoid dying out.

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.
