Growing Eucalyptus Indoors Successfully: Here’s How

Growing Eucalyptus Indoors Successfully: Here’s How

The plant commonly known as eucalyptus is originally from Australia and Southeast Asia.

Most people think of essential oils, koalas, or floral arrangements when they think of eucalyptus.

There are actually hundreds of varieties of eucalyptus that have different scents, leaves, and sizes. 

Can you grow eucalyptus indoors? While this sun-loving plant does best when planted outdoors in Zones 8-11, it is possible to grow eucalyptus indoors. You’ll need to place the plant in the sunniest location in your home and consider keeping it outdoors during the warmer months. Water consistently, and fertilize every 4-6 weeks.

In the wild, eucalyptus trees can grow to be over 300 feet tall, and shrubs can be over 30 feet tall.

Luckily, there are plenty of compact varieties that look lovely indoors and still add that relaxing aroma to the air.

This article will tell you everything you need to know to successfully grow eucalyptus indoors. 

Indoor Eucalyptus Care

You can purchase a eucalyptus plant from the nursery or grow your own from seeds or cuttings. Either way, the care will be the same.

Since these plants love sunlight, some people keep their eucalyptus indoors during the cold winters but move them outside as soon as the weather warms up so they can enjoy all that natural, bright sunshine.

How To Pot a Eucalyptus Tree

You want to choose a pot that is the appropriate size for your specific plant. A container too large will hold too much soil and excess moisture. 

Plant your eucalyptus in a well-draining potting soil. A houseplant mix works well, but if it is too dense, add a little perlite to aid in drainage. 

Eucalyptus Light Requirements

Eucalyptus plants love sunlight! They should be placed in a location that receives as much light as possible.

A great option is a south-facing window with a few hours of direct sunlight. If you do not have a sunny spot in your home, you can use grow lights for your eucalyptus.

Be sure that you choose height-adjustable lights like these to accommodate for the growth of your tree.

Watering & Fertilizing Indoor Eucalyptus

Potted eucalyptus plants cannot handle droughts the way outdoor plants can. This is because soil in pots tends to lose moisture faster than the ground. 

You also do not want to overwater the eucalyptus plant and risk root rot. It is best to check the moisture level in your soil before watering.

Water your plant when the top couple inches of soil are dry. 

To give your indoor eucalyptus the nutrients it needs, add a balanced or high-potassium liquid fertilizer (find an organic high-potassium food here) during the growing season.

You do not need to apply it frequently; every 4-6 weeks is plenty.

Pruning an Indoor Eucalyptus Plant

All eucalyptus plants are fast growers and will need pruning indoors. Regular pruning maintains the shape and size of the plant.

Save any major pruning for the spring so that the plant has a chance to rebound during the growing season.

When pruning your plant, you can use the cuttings in floral arrangements or as an aromatic decoration in bathrooms.

How Long Does Eucalyptus Live Indoors?

Eucalyptus is a perennial evergreen that can live indefinitely when receiving proper care.

The most important factor to keeping your eucalyptus alive for many years is providing plenty of sunlight.

Anything less than a few hours of direct sunlight is sub-optimal for a healthy eucalyptus plant. 

When To Transplant a Potted Eucalyptus Outdoors

You can transplant your potted eucalyptus to the outdoors at any age. However, these plants are hardy in Zones 8-11 and cannot survive below freezing temperatures. 

Transplant your potted eucalyptus in the springtime when the weather is warm and there is plenty of sunshine.

This gives the plant everything it needs to establish strong, healthy roots in its new environment.
