Eucalyptus is the key to a relaxed home – here's how to grow your own
Eucalyptus trees, known for their rapid growth, aromatic grey-green leaves and colourful peeling bark, can be a wonderful addition to your garden. Providing numerous ecological benefits, including shade, habitat for wildlife, and improved air quality, their menthol-like fragrant leaves are also known for attracting pollinators. However, with over 500 species ranging from towering giants to diminutive shrubs, what's the best eucalyptus for your outside space?
Good news: this ornamental tree, which is native to Australia, is pretty easy to grow and is generally low maintenance. Here's some expert advice on growing eucalyptus at home.
Choosing the right varieties
'If you want to grow eucalyptus in your garden, I highly recommend starting with eucalyptus gunnii, also known as cider gum,' says Chris Bonnett, founder of GardeningExpress.co.uk. 'It is a very common and hardy variety that is well-suited to most climates. Whether you plant it in full sun or partial shade, the plant will look great all year round. Cider gum also requires minimal maintenance and grows very quickly.'
Other popular eucalyptus varieties that are readily available in the UK include the snow gum and mountain gum species.
'There are over 500 species of what we usually think of as eucalyptus, now classified across at least three genera (Eucalyptus, Corymbia, and Angophora),' says Igor Lacan, Ph.D, urban forestry advisor at the University of California Cooperative Extension, who warns that some species can be invasive (they can successfully escape cultivation and spread), so choose wisely.
Ideal eucalyptus growing conditions
Eucalyptus trees prefer sunny locations and well-drained soil. While many species are drought-tolerant, it's essential to match the specific requirements of the species to your garden's conditions. Most eucalyptus trees thrive in a variety of soil textures and pH levels, but they will not flourish in waterlogged areas. Small creamy-white fluffy flowers, rich in nectar, will form on established species at various times of the year.
'When planting eucalyptus, make sure to place it in full sun and well-drained soil, ensuring the spot is sheltered to protect the plant from strong winds,' explains Chris. 'Water deeply but infrequently to encourage deep root growth, and apply a balanced, slow-release fertiliser in spring to promote healthy growth.'
Harvesting eucalyptus leaves
Eucalyptus is loved for its aesthetic appearance (and its scent), so it makes for a popular plant in the home – this is often why it's used by floral designers as the final flourish in bouquets. If fresh and kept in water, your eucalyptus stems will last a few weeks, and it maintains a striking sculptural shape for months when dried.
Dr. Lacan suggests eucalyptus pulverulenta, also known as the silver mountain gum, which is commonly harvested for its unique appeal.
Beyond using it for floral displays, wreaths or garlands, you can use eucalyptus leaves in the home as an air freshener, potpourri, or to create a bath bouquet. To do this, simply hang a bundle of eucalyptus stems to your shower head — the steam activates the essential oils in the plant, helping to release aromatherapeutic properties to boost your mind and body.
Common mistakes with eucalyptus
One of the most frequent errors made by home gardeners is planting large maturing eucalyptus in restricted, or small spaces.
'The typical mistake is to plant a large maturing species (like E. globulus) in restricted spaces. Then the tree grows up to its natural large size and causes all kinds of problems,' says Dr. Lacan. Always choose a species that matches your garden size and be aware of its growth potential.
'Some of the small-maturing species, and shrubby species, can live in containers,' Dr. Lacan adds.
Managing pests and diseases
Just like any other plant, eucalyptus trees are susceptible to pests and diseases.
'The most common pests to look out for are scale, aphids, vine weevils and mealybugs. While not a widespread problem, some beetle species may also feed on eucalyptus leaves, more likely affecting young or stressed trees,' says Chris. 'A common disease associated with eucalyptus is leaf-spot disease which causes dark spots on the leaves, leading to premature leaf drop. Eucalyptus plants can also experience root rot in poorly drained soils and develop botrytis disease which appears as sunken, dead areas on the bark.'
Pruning eucalyptus
'These trees are fast growers, so regular pruning is essential to maintain their shape and size,' Chris explains. Regular pruning not only promotes growth but also enhances air circulation and reduces the risk of disease.
Note that some eucalyptus species will require lots of structural pruning when young to form a well-structured canopy, adds Dr. Lacan.
