Timing

Timing
Sow indoors 10-12 weeks before the last frost date. That’s mid-winter for most gardeners. Germination should occur in 14-21 days.

Starting

Starting
Lightly cover the seeds and keep moist and warm until germination. Once the seeds sprout, remove from bottom heat and remove any humidity dome. It seems that Eucalyptus seedlings are prone to damping off, so provide bright light and air circulation around the plants. At 10-13cm (4-5″), transplant on to a container if keeping indoors. Or transplant outdoors once night time temperatures are consistently above 10°C (50°F).

Growing

Growing
Plant in full sun in well drained, moderately rich soil. This Eucalypt can be grown in a container as an indoor houseplant and pruned to a compact size. Outdoors, take branches as needed for floral displays. They can also be dried or preserved with glycerin.
