5 Drought-Tolerant Trees

During your days in school, your teacher taught you about the essential needs of trees. So, it is common knowledge that in order to grow well, these trees require sunlight, water, nutrients, and the appropriate type of soil. 

But only a few people are aware that some trees require less water than others. These so-called drought-tolerant trees are the perfect addition to your garden space if you have little time, but you want trees for privacy and added property value. 

Moreover, this type of trees can survive arid and dry conditions, which means you don’t have to worry about consuming too much water during the hottest months. 

So if you want to save water, money, and time, consider these five attractive trees that require the least water in your outdoor space:

  1. Northern Red Oak (Quercus rubra)

Due to its maroon-shade foliage during winter, Northern Red Oak is one of the most popular backyard trees that homeowners want outside their property. This fast-growing tree develops a sturdy trunk and rounded crown with age. It reaches from 18 to 23 metres tall and 13 to 15 metres wide ─ which can be a perfect height and width for hedge trees

Caring for Red Oak is easier compared to other trees as it only needs regular moisture. It prefers full sun and can tolerate acidic, loamy, sandy, well-drained, or clay soil. 

Furthermore, the best time to plant Northern Red Oak is during spring or fall to avoid the hot climate. It needs deep watering at least once a week. At the time it matures, it can already become drought-tolerant.  

  1. Cootamundra Wattle (Acacia baileyana)

In Australia, Acacia is the country’s largest genus of flowering plants with about 1,000 species identified. Meaning, you have a variety of choices available for your garden space. And a classic tree that can magnificently grow in your lawn is the Cootamundra Wattle, which is native to NSW.  

As a garden owner, you don’t want to keep a monotonous colour mood in your backyard. With its attractive yellow flowers, Cootamundra Wattle can enhance the overall ambience of your outdoor space. 

Aside from being an evergreen, Cootamundra Wattle only needs a few requirements. It survives best in full sun and acidic, well-drained, or moist soil but can grow on other types as well. Furthermore, it can undoubtedly adapt to changing climate conditions and perform well with low amounts of water once established.   

  1. Japanese Tree Lilac (Syringa reticulata)

Japanese Tree Lilac is a large shrub or small tree that can grow from 6 to 9 metres and 4.5 to 6 metres wide. It can be a single or multi-stemmed tree with clustering and musky-scented white flowers that bloom in early spring. 

It can tolerate light shade but grows the best in full sun with medium moisture condition and well-drained soil. Moreover, it can adapt well to an urban environment but needs good air circulation. 

Japanese Tree Lilac can survive most pest infestations and disease problems. It is resistant to mildew, bacterial blight, scale insects, and lilac borders. Meanwhile, it needs deep watering every 7-10 days as long as there is well-established drainage

  1. Eastern Redcedar (Juniperus virginiana)

Eastern Redcedar is a sought-after tree in most lawns since it’s an excellent landscape enhancer. Its dense pyramid shape is perfect as windbreaks and screens. It can reach 12 to 15 metres in height and 2.4 to 6 metres in width. In late summer and fall, it produces blue berry-like fruits, which adds vibrance to your garden.  

It prefers full sun and grows on almost all kinds of soil. Moreover, since its fruits attract birds, it can effortlessly propagate. Tree maintenance for Eastern Redcedar can be minimal since it is tolerant to drought, heat, salt, and wind once established. 

  1. Jacaranda Tree (Jacaranda mimosifolia)

One thing is certain. Jacaranda tree is truly a head-turner due to its purple-blue, fragrant, and trumpet-shaped flowers that bloom enchantingly. Most garden owners consider it as an ornamental tree that is perfect when formed in a row. It can grow up to 15 metres tall and 9 metres wide. 

It blooms best in full sun and well-drained soil. Also, it thrives nicely in warm conditions and tropical climate areas. Unfortunately, it does not go well with below zero temperature, and its first two winter years are crucial for its growth. Once it survives the first two years,  frost is not a problem anymore. Lastly, it is drought-tolerant, but watering is required during the dry season. 


Taking care of trees can be quite a hassle. Probably, with your busy schedule, you won’t have the time to water them, especially during the driest season. If that is the case, it is best to invest in trees that require less water than others. You cannot only save time but money and resources as well.
