Eucalyptus - Key Growing Information

A planting of eucalyptus, excellent as a foliage or filler item in cut flower arrangements.

DAYS TO GERMINATION:

Germination takes roughly a week (7–10 days) when kept at 75–80°F (24–27°C), or two to three weeks (14–21 days) at a cooler 65–75°F (18–24°C). Keep humidity high until seedlings appear.

SOWING:

Transplants are recommended: sow into 128-cell flats or your usual containers 8–10 weeks before planting out, covering the seed lightly. Water from below or mist so seed stays put. Seedlings dislike root disturbance. Harden off and plant out after frost danger has passed; in short-season areas, a warming plastic mulch helps.

LIGHT PREFERENCE:

Full sun.

PLANT HEIGHT:

Varies.

PLANT SPACING:

Space plants 12–24" apart.

HARDINESS ZONES:

Hardy in Zones 9–11. It can be kept as a perennial where there's no frost, or in cooler areas with good frost protection.

HARVEST:

Cut once the leaves feel leathery and the stems have turned woody. Hang stems to dry, or stand them in a mix of glycerin and water; glycerin-treated stems stay supple and durable and keep a freshly cut look.

SOIL REQUIREMENTS:

Fertile soil with good drainage.

USES:

Superb fresh or dried cut foliage; also an accent in beds and a fine container plant.

ALTERNATE NAMES:

Gum, cider gum, euc
