Not every eucalyptus tree is built for the freezing cold. If you’re wondering whether your plant can handle a dip in temperature—or how to keep it cozy until spring—you’ve come to the right place. Follow these simple tips, and you won’t have to lose any sleep when the frost hits.
What to Look For
The easiest way to tell if your eucalyptus is a hardy variety is actually by the color of its flowers. Generally speaking, if your plant sports red or yellow blooms, it’s a sun-lover that won’t tolerate frost. On the other hand, the *Eucalyptus gunnii* (Cider Gum), which features creamy white flowers, is the champ of cold weather. These hardy guys can often handle temperatures as low as -4°F (-20°C), but they still appreciate a little extra TLC.
In the wild, the ground acts as a natural insulator for the roots. However, if you have a potted eucalyptus, it’s much more sensitive to the cold. To help it survive the winter outdoors, wrap the pot in garden fleece or burlap. Make sure to pull the material upward to cover the soil surface, too. If you have a taller “standard” tree, you can even slip a breathable frost bag over the crown for protection.
If you have a more delicate variety—or just don’t want to risk it—you can always bring your eucalyptus indoors. Just keep in mind that indoor life requires a bit of balance: find a sunny spot and water regularly, but be careful not to overdo it.
Pro tip: Use low-lime water for your eucalyptus, such as:
- Collected rainwater
- Filtered water
- Tap water that has sat out for a few days
Post-Winter Care
Once the winter chill fades, your plant will be ready to kick off its growth phase. To give your eucalyptus a head start after its winter nap, give it a little boost with a suitable plant fertilizer for about a week. After that, stop fertilizing; too much of a good thing can actually damage the plant.
Spring is also the perfect time to prune your eucalyptus. Pruning isn’t just about keeping it at a manageable height or looking pretty—it actually encourages healthier, more vigorous growth. Since eucalyptus is a fast grower, don’t be afraid to give it a significant haircut; it’ll bounce back before you know it!
