Fast Growing Evergreen Shrubs

I get a lot of questions about fast-growing evergreen shrubs. We all like privacy in our gardens, and sometimes there is a need to create a hedge or buffer quickly, but avoiding the blandness of conifers and the problems of Leylandii.

If you are planning a hedge or screen in proximity to your neighbours, be aware of the law. As an alternative, you could consider planting a deciduous hedge, such as a Fagus, the common Beech, which is fast growing and not evergreen. It gives privacy but is a less dense shrub, creating less shade. 

You can plant shrubs at any time of year, provided it is not a cold spell. The main cause of shrubs failing to thrive is a lack of water. After you plant a shrub, you should water it regularly for weeks to help it establish. This makes autumn a good time to plant shrubs because it is much wetter than any other season.

Planting a fast-growing shrub is good in some ways as it produces an instant result. By its nature, a fast-growing hedge produces a lot of growth quickly and so will need regular pruning. It can also produce very dense shade around it. It is important to view the space and surroundings before deciding. For example, Portuguese laurel is correctly billed as a fast-growing evergreen, but it also gets very large and in around 7 years can reach 7m and 2/3m wide, which if planted on a boundary, could swamp the area and be unmanageable. 

It is a question of balance. The need for privacy or cover weighed against the ultimate size of the evergreen, how quickly and the amount of maintenance. It is great to get the cover, but you do not want to have to spend time or money cutting back to prevent the evergreen from taking over. With that caveat, there are a good number of easy, fast-growing evergreen shrubs. 

There are also many lovely evergreen shrubs which a moderately fast growing. These can be easier to maintain, less pruning, and more suited to the average sized garden. Suttons have a wide range of shrubs, including those featured many at discounted prices. Browse the collection.

Did you know some shrubs can reduce air pollution. If you live near a busy main road, planting these shrubs can help combat air pollution. Check out 10 best hedges and shrubs for wildlife and pollution busting.

Thinking of planting bamboo to provide a quick screen? plant with caution, as bamboo can be very vigorous.  Check out my guide to planting non invasive bamboo in the garden for hints, tips and a complete list of invasive and noninvasive bamboo varieties.

Can I plant Leylandii and other hedge issues?

It is not illegal to plant Leylandii, but there are restrictions and specific regulations concerning evergreen hedges. Your neighbours can complain to the local council if the trees or hedge you plant breaches the Anti-Social Behaviour Act (2003)  

This law applies to hedges consisting of two or more evergreens, or mostly evergreen trees (not to individual trees) and hedges over two metres affecting domestic property. This means is that if you pick a shrub which is quick growing, you will need to be scrupulous with maintenance and pruning so as not to offend neighbours and the law. If in doubt, take legal advice from an appropriate source, such as Citizens Advice or a solicitor.

Hedges for Health

If you live in an urban area, or close to a busy road, a hedge can help clean the air around your property. There has been some very useful scientific research by the RHS about this issue, and some shrubs are better at collecting particulates than others. Planting a hedge really can help to improve the air quality around your home.
