Care of Eucalyptus Plant 

They are low-maintenance plants with simple needs. The leaves of the small eucalyptus plant have beneficial uses. Its oil can be extracted to make perfumes and medicines. But, since it is toxic, always wear protective gloves when handling them.

Eucalyptus Light Requirements

When growing eucalyptus indoors. Always ensure you provide enough access to direct or full sunlight.  They need at least 6 hours of direct sunlight to thrive. Growing them in areas of low lighting gives them stunted leaf growth. 

Place them in a room, next to a south-facing window. This presents them with the most sun needed for the day. They can grow in areas with filtered sunlight. But they would need longer exposure and their growth might be poor. 

Eucalyptus Watering Requirements

The Eucalyptus cinerea can do without water for long periods. But they still need water to stay fresh. Depending on the heat of the season, watering should be kept moderate.  Once every 4 days is good in summer. However, during winter or fall, limit it to once a month or 2.  

Aim for moist soil. You can achieve this by letting it dry a little before the next watering session. Make use of a moisture meter as it helps with appropriate watering.

If you don’t have that, then feel the soil with your fingers. If the topmost part is a little dry, proceed to watering. Too little watering can cause the plant’s leaves to shrivel up. And excess watering opens the roots up to fungi. This can lead to root rot.

Ensure you use rainwater for your watering. Tap Water is filled with chlorine and this is harmful to the plant. You can also use a water filtering system, to get rid of chlorine from tap water.

Eucalyptus Soil Requirements

Keep the pH level of the soil between a little acidic and neutral. An appropriate range would be between 6.2 to 7.0.

Eucalyptus Temperature and Humidity Requirements

Try regular misting to achieve this indoors. You can also make use of a humidifier, but it can be expensive.

Temperature levels should be kept between 60 to 75 degrees Fahrenheit. They would need protection against the cold winter season.
