How To Plant a Conifer Hedge – The beginner’s guide

Last Updated on

Conifers are a wonderful option for a close-growing hedge that offers natural privacy, protection against the wind, and a beautiful backdrop to your garden. Conifer shrubs and trees can be found in two varieties the first of which is a container-grown conifer the second of which is called rootball conifers.

The rootball conifers are grown in the ground before being lifted from the ground and a sacking placed around the rootball to hold the root system together. These are usually more affordable and often larger conifers are sold like this. The only downside is they are usually only available from October for a few months while they are dormant.

Pot grown conifers can be purchased all year round and are often more expensive, they are often also slimmer as they have been confined to growing in a pot, however, they often bush out once planted in the ground.

Planting a conifer hedge

When you set about planting your Conifer hedge you want to do it either in the springtime or in the autumn while the ground is still warm and they will put out some root before winter really sets in. In general, springtime is best, particularly early spring because it allows the root system time to establish itself and has all summer to get established. Similarly planting an Autumn allows the plants to establish themselves a little before winter time so that they can establish their strength long before the first spring.

You can plant pot grown conifer hedging throughout summer without any problems but you will need to keep a close eye on watering for the first few months. You should never try and plant root balled conifers in summer as they usually do not take and often die.

 

Step one

Before you start planting, you want to soak the root system of a rootballed or pot grown conifer in water. Fill a bowl or large bucket with temperature water and allow the plant to rest for around an hour. Once that is done remove it from the water and cut off any dead or damaged roots but make sure you only use sharp good pair of secateurs to do so.

If you are using a container-grown conifer all you have to do is remove it from the container as the roots will not be damaged, carefully loosen the roots if they are very compact and prepare to plant.

Similarly planting an Autumn allows the plants to establish themselves a little before winter time so that they can establish their strength long before the first spring.

Step two

Measure the depth of the plants rootball from the base of the trunk to floor level. Dig a trench that is the same depth as that measurement and a little wider than the root balls.  If you are planting a container-grown conifer simply make sure that the hole you dig is the same depth as the container in which the plant was purchased. What you want to avoid is planting them any deeper than they were originally planted.

Step three

Place the conifers inside the trench you have dug such that the top of the root ball ends up at ground level. Make sure you do not damage the root system as you are doing this. This will also give you the opportunity to plan where you are going to plant the conifers and how much space will be between them. In most cases, conifers should be spaced approximately 60cm apart but you can read more on spacing conifers here.

Step four

Mix in organic compost into the soil that you removed from the holes you created so that you can improve the overall nutrient content and then fill in the Conifer with the new mixture. You want to pack in this mixture around the root system in order to hold your conifers upright, in place but make sure you don’t damage the roots as you are doing so.

Step five

Once this is done you should saturate the soil with one good watering and make sure that you water enough that the soil fills in the spaces around the roots and removes any air pockets. You might find that as the water settles, the soil level drops in which case you might need to add a little bit of extra soil to compensate. During these initial stages, you will need to water more heavily so that the roots are able to establish themselves, about three times per week but sometimes daily if it’s been very warm. The soil should remain evenly moist but not to wet. Remember to water regularly for the first few months and keep an eye on the watering thereafter for the next 12 months. After this, they generally look after themselves once the root systems are established.

 

Tip

  • If you are planting a hedge with an eventual height of around 6ft or under, space plants around 2ft apart. If you want to plant a very tall hedge, plants can be spaced as much as 1 meter apart.
  • If you don’t want to dig a trench, space the plants according and dig holes that are the same depth as the root ball, maybe a little deeper allow for any organic matter you might add and dig holes twice as wide. Space the conifers in the final positions before digging the holes
  • Bare root conifers, which are conifers that have no soil around the roots are very temperamental. We recommend avoiding bare root conifers and buy either pot grown on root balled conifers with the soil around there roots. The only exception is if you are planting yew trees which are a type of conifer and they grow well from bare root unlike most other conifers.
