How far apart to plant conifer hedging – The spacing guide
Last Updated on January 21, 2020 by John
Conifers make for a lovely addition to your home and what’s more, they can be used quite effectively as hedging. Given the different varieties, you can choose to create something such as a shorter, smaller privacy screen that serves to divide different sections of your garden into individual components. You can also opt to grow them as a hedge along the perimeter which is particularly effective when it comes to creating privacy and blocking out heavy winds or noise from street traffic, two great conifers for doing this is leylandii and Thuja plicata with the latter being my favourite choice. In general, you should space conifers 60cm (2ft) apart, if you plan on growing a taller hedge, for example over 8-10ft, you can space them up to 100cm apart.
That said when you plant your conifers you need to make sure that you space them apart properly and evenly and add plenty of organic matter to the soil when planting.
Why spacing matters
When you are first creating a hedge you will likely have younger plants that have yet to reach full maturity at which point they will become much larger both in height and spread. For smaller, younger plants you need to make sure that you space them apart enough that when they reach maturity they don’t grow into one another’s territory to much. While you do want them to grow into one another well enough to create a full hedge with no gaps, if they are too close together it will block the proper airflow and lend itself to an increased risk for diseases such as fungal infections and bacterial infections. If they are spaced too far apart your hedge may not form a solid hedge and may even struggle to close the gap as the base of the plants.
Spacing Conifer hedging
Properly spacing is going to be somewhat contingent upon the plant type. Most conifers should be spaced between 60cm and 100cm apart. Hedges that have plants 60cm apart will grow into space in between much faster but you can achieve a very effective hedge no matter the distance so long as it falls into that frame. If you are planting large, bushy varieties that grow up to 180 cm or larger you want to plant on the higher end of that spacing, 100 centimetres apart. This is also the appropriate measurement if you want to create a very tall hedge rather than a shorter wider hedge. As a rough guide, if you want to establish a hedge to around 6ft or under, space 60cm apart. If you want to grow a very tall hedge, space anywhere between 60-100cm apart.
