Q. How do I care for a eucalyptus plant indoors?
Thank you for our question about the care of eucalyptus. Not sure what species you are growing, but usually Eucalyptus gunnii is the most suitable for indoor growing because ordinarily it cannot grow more than 12 - 18 inches a year in a pot. It remains a reasonable size for several years.
The juvenile leaves encircle the main stems, are more or less heart-shaped, 2 - 3 inches across and of a dull, gray-green color heavily sprinkled with white powder. The leaves of very young shoots are usually suffused with pink, particularly when the plant is grown in direct sunlight.
And speaking of sunlight the plant needs full sunlight (at least 6 hrs/day); sunlight from a southern exposure is best.
Another species, E. globulus, can be grown indoors only for a year or two, after which its rapid growth — 3 - 4 feet a year — makes it too large. The juvenile leaves are almost stalk-less, somewhat heart-shaped, 2 - 3 inches across, and gray-blue sparsely sprinkled with white powder.
Temperature for eucalyptus can be warm or cool. While plants are actively growing, water moderately, watering thoroughly throughout the soil, but let the top third of the mixture dry out before re-watering. Trees need well-drained conditions, so do not water too soon. Also repotting may need to be done twice a year, but at least once a year, into a pot one or two sizes larger. Make sure that the potting mixture entirely covers any swollen root structure when repotting is needed.

- I have a cutting or pinch off of a Eucyliptis. I tried to get roots which about the size of hairs but didn't get any only clean wedge cuts (I was afraid of damaging the root ball which was about 4' diameter. can I grow these. ? there are two .
should I start in water or soil? and can input root hormone in water if that's what I'm using first?
- Propagation of eucalyptus is by seed, which you sow in spring and germinate at a temperature of 65 to 75 degrees F.
