Yew Hedging

Yew plants are quite slow growing at around 30cm per year, depending on your location (plants generally grow faster in the warmer South & West than in the cooler East & North of Great Britain) and your local conditions (wind-shelter and full sun are ideal).
 

Yew has a special feature that does not apply to most other hedge plants: when you cut the leading stem (which removes the apical bud, i.e. the topmost growing point), their growth slows dramatically from about 30cm per year down to less than 10cm per year. 

Bear in mind that it is common for most plants to put on very little height in their first year after being transplanted into your garden.
There is nothing wrong with this: they are laying down roots first, in readiness for growing upwards and filling out.

How big does a Yew hedge grow?

Yew is suitable for hedges from about 1 metre, up to as tall as you like! For a shorter hedge, Common Box or Box Leaf Holly are good formal alternatives.

You can plant Yew hedging at any time of year, except when the soil is frozen. 
 

The best time to plant Yew is in winter (November to March), using bareroot stock, which is cheaper, easier to carry and plant, and tends to establish even better than the pot grown equivalents. 
 

Our film on How to Plant a Formal Hedge demonstrates beech, but the process is the same with Yew.

The advice below is supplemental to that film and applies if you have well-drained soil; see our specific instructions on how to plant yew where drainage is bad if you do not.
 

Preparing the ground for a Yew Hedge
 

Dig a trench about 30cm deep and 50-60cm wide.
Remove roots, perennial weeds, stones and other rubbish and incorporate plenty of well-rotted organic matter.
Break up any clods and work the whole together well, so you have a fine, crumbly planting medium.
Ideally, this should be done in advance and left to weather prior to planting. However, you can prepare and plant on the same day.

Spacing and Planting Yew Hedging
 

Depending on size, space your yew at between 2 and 3 per metre in a single row.
A Yew hedge is meant to be formal, so use a string stretched between canes to make sure you are planting straight.
 

Spread the roots of each plant out well.
Water the bare roots and sprinkle with Rootgrow.
Check the spacing between plants one last time before you return the soil around the roots.
Firm it down as you go, making sure that each yew plant ends up at the same level in the soil as it was before we lifted it. Hold the yew stem so it does not sink with the soil.
 

It is a bad error to plant your yew too deep as the bark on young plants can rot easily.
Aim to end up with a bed that is slightly ridged: 2-3cm higher in the middle than at the edges.
This helps water run away from the trunks of the young yew hedge plants, and the ridge itself will erode so the danger of rotting bark is minimised.

Water well and admire your handiwork with a cup of tea.

The ideal time to trim a Yew hedge is in September or October, because this should let you get away with one trim per year. 
 

But you can trim it anytime you like without harming the plants, and for a really tidy look, a second trim as needed in Spring or Summer might be necessary.

Yew plants will regrow from old wood, so they forgive mistakes and can be hard pruned if necessary, unlike most conifers. 

Important note: Once you cut the growing tip off the leading stem, the rate of growth slows right down to as little as 5-10cm per year.
Therefore, don't the top of your yew hedge until it has reached its final height. Only clip the sides.

In the first winter after planting, firm down the soil after hard frosts.

In the first year after planting, water yew well when the soil is dry, but don't water at all when the ground is damp: if the earth is damp 3cm down, there is no need to water.

A lot of water infrequently is better than little and often.
