Grampians gum · Eucalyptus alpina
In mild counties and frost-free areas, grow in sharply drained or sandy, neutral to acid soil in full sun with shelter from winds; in frost-prone areas, grow in a cool or temperate greenhouse, in a mix of lime-free potting compost and grit, in full light with good ventilation. Water freely in spring and summer and apply a general fertiliser monthly, water sparingly in winter. See eucalyptus cultivation
