You might be most familiar with eucalyptus (Eucalyptus cinerea) as a favorite food of the koala. This evergreen tree can grow to 60 feet high or more in its natural Australian environment, but in home gardens, it usually remains small, at around 6–10 feet high. It features reddish-brown bark that peels on the smaller branches. The leaves are a silvery to blue-green color, and they give off the plant’s distinct menthol-like fragrance when bruised. Eucalyptus trees are best planted in the spring. They have a fast growth rate and can gain several feet per year. It's important to note that the bark, leaves, and sap of eucalyptus are toxic both to humans and pets.

How to Plant Eucalyptus

When to Plant

When growing eucalyptus from seeds, start them indoors 10 to 12 weeks before your area’s projected last frost date in the spring. If you have a nursery plant, transplant it into the garden in the spring after the danger of frost has passed.

Selecting a Planting Site

Choose a planting site that gets lots of sun and has soil with sharp drainage. Also, ensure that there is enough space to accommodate the tree’s full height and spread. Make sure no nearby trees or shrubs will block sunlight from a young eucalyptus plant. This plant also can be grown in containers as well as indoors when given enough light.

Spacing, Depth, and Support

If you’re planting multiple eucalyptus trees, space them at least 8 feet apart. Plant them at the same depth they were in their nursery pot. These trees generally do not need any staking or other support structure on which to grow.

Eucalyptus Plant Care


Eucalyptus likes a lot of light, so settle your plant somewhere in your landscape that receives at least six hours of direct sunlight daily. Likewise, eucalyptus plants grown indoors should be kept near a bright window, preferably one that faces south.


Eucalyptus can tolerate most soil types, but it needs soil with good drainage. For container plants, use a well-draining potting mix. A slightly acidic to neutral soil pH is best.


Eucalyptus is somewhat drought-tolerant once it's established. However, it really doesn't like to be left dry for long periods, and doing so might cause it to drop leaves or branches. A good rule of thumb is to water when you can stick your finger into the soil and feel dryness at your fingertip. This often will amount to watering weekly if you haven't had rainfall, especially for container plants.

Temperature and Humidity

Eucalyptus prefers warm temperatures between roughly 65 and 75 degrees, and it likes a moderate humidity level. It cannot survive prolonged exposure to temperatures below 50 degrees. So if you're growing your plant in a container, bring it indoors if you expect chilly temperatures.


If you're growing your plant in the ground, it typically won't need fertilizer. However, container plants will deplete their nutrients more quickly. So fertilize them with a low-nitrogen houseplant fertilizer throughout the growing season, following label instructions.

Types of Eucalyptus

In addition to Eucalyptus cinerea, there are hundreds of other eucalyptus species. They include:

  • Eucalyptus globulus: Known as blue gum, this species features smooth bark and is particularly adaptable to a variety of growing conditions.
  • Eucalyptus gunnii: Commonly referred to as cider gum, this species has better cold tolerance than most other eucalyptus species.
  • Eucalyptus platypus: Commonly called moort, this is an especially hardy species that can tolerate heavy soils, cold, and drought.

Harvesting Eucalyptus

Beyond its obvious beauty, eucalyptus can also be harvested for various uses. Wait until later in the growing season to harvest mature leaves and branches. If you just want the leaves, simply snip them off with pruners or by hand. Air-dry them on a paper towel or drying screen in a cool spot out of direct sunlight. Wait until the leaves are slightly leathery or crispy, and then store them in glass jars with tightly sealed lids. The dried leaves can be used in teas and to flavor other drinks.

If you would like to use the branches for crafts, one of the best ways to preserve them is with glycerin. Simply prune off a length of branch that's to your liking. Then, choose a container that is large enough to hold your entire eucalyptus branch. In a separate container, mix one part glycerin with two parts boiling water, and allow it to cool. Pour some of the cooled liquid into the large container, and then insert the cut end of the eucalyptus branch until it's standing in about 3 inches of liquid. Keep the container in a cool, dark place, and inspect the branch weekly. Add more liquid as needed to keep it at the optimum level. It can take two to six weeks for the branch to dry. The leaves will turn from green to purple or silver, and they’ll be soft and smooth. Once dried, remove the branch from the container, and hang it upside-down for two to three days before using.

How to Grow Eucalyptus in Pots

Eucalyptus plants are often grown in containers outside of their hardiness zones. This allows gardeners to protect their plants from the cold by bringing them indoors. However, many gardeners treat container eucalyptus plants as annuals, starting with new plants each year because of their rapid growth rate. This allows them to remain manageable as houseplants and on balconies and decks.

These plants don’t like their roots to be disturbed. So it’s best to start with a large container to avoid having to repot. A 5-gallon container is a good size. And while unglazed clay is an ideal material to allow excess moisture to evaporate through its walls, you might want a plastic container that’s lighter to move around. Just make sure any container has ample drainage holes, and use a quality fast-draining potting mix. 


Eucalyptus trees generally don’t need much pruning. However, you can prune overgrown, broken, or misshapen branches to keep the plant looking attractive. The best time to do so is in the summer, but avoid pruning during very humid weather.

Propagating Eucalyptus

Eucalyptus trees are most commonly grown from purchased seeds or nursery plants. Home garden trees don’t often flower and produce their own seeds. They also can be propagated via cuttings, though this isn’t always successful. But this is an inexpensive and convenient way to get a new plant, especially because eucalyptus can be hard to come by at garden centers. The best time to take cuttings is when a tree is between 2 and 12 months old; rooting mature stems is difficult. Aim to take your cuttings in the late summer. Here’s how:

  1. Prepare a small pot of three parts composted tree bark to one part perlite. Add a slow-release fertilizer, following label instructions for the size of the pot. Moisten the growing medium.
  2. Use sterile pruning sheers to cut a stem that’s around 5 inches long with four to eight leaves. Cut just above a leaf node.
  3. Remove the leaves on the lower half of the cutting. 
  4. Dip the cut end in a rooting hormone, and then plant it in the growing medium almost up to where the leaves are. 
  5. Keep the container in bright, indirect light in a room that’s around 70 degrees. Make sure the soil remains lightly moist.
  6. Roots should form in about a month. At that point, you can move the new plant to a sunnier spot and gradually space out waterings. Once the weather is warm enough, bring it outdoors for progressively longer stretches before planting it in the garden.

How to Grow Eucalyptus From Seed

Seeds first must be chilled in the refrigerator for two months before planting. Sow them in the late winter indoors roughly 10 to 12 weeks before your area’s last projected frost date. Use a seed-starting mix in peat pots that you’ll eventually be able to plant right into the soil to avoid disturbing the roots. Sow seeds on top of the growing medium, only lightly covering them. Place the pots in a warm spot with indirect bright light, and keep the growing medium moist but never soggy by misting it. Seeds should germinate in two to three weeks. Once the seedlings are about 6 inches tall, they’re ready to go outdoors. 


If you’re growing a container eucalyptus plant outside of its hardiness zones, you must bring it indoors to survive the winter. Do not let your plant be exposed to frost, which can damage or kill the foliage. Place it near your brightest window, preferably a southern-facing one, for the winter. Do not fertilize the plant, and slightly back off on watering.

Common Pests

Eucalyptus is fairly free of any major pest or disease issues. But you might occasionally spot eucalyptus long-horned borers, especially on stressed plants. Holes in the bark, oozing sap, and foliage discoloration are signs of an infestation. Remove the infested area of the plant immediately, as insecticides are not effective against borers.
