After a wildfire up to 2 million Mountain Ash seedlings germinate per hectare.

There are three main seedling stages: the two leaf stage with plants up to 2.5 cm in height (up to 3 weeks after germination), 10-15 cm tall plants with 3-5 pairs of leaves (3-4 months), and rapidly growing seedlings up to 3 m in height (2 to 4 years).

The tap root increases in size from 20 cm in the first year to over 1.5 m in the third year.

The lateral root system expands from 7 cm in the first year to over 2 m in the third year.
