Winter Tree Pruning in Dublin and Which Trees to Leave Alone

Why Winter Tree Pruning Suits Most Dublin Gardens

Winter tree pruning, carried out between late November and February while most deciduous trees are dormant, is the best time to shape, thin and make safe the majority of garden trees in Dublin. With the leaves off, the branch structure is easy to read, the tree loses less energy and nesting birds are not yet in the canopy.

Below we explain why the dormant season works, which trees should not be cut in winter, the methods our tree and hedge cutting team uses, what to check before any cutting starts, and what affects the time and cost of the job.

What Happens to a Tree in the Dormant Season

Once a deciduous tree drops its leaves in autumn, growth slows almost to a stop and the tree draws its stored sugars down into the roots and lower trunk. Cutting at this stage removes less of the energy the tree has built up over the summer, and the wound has the whole of spring to begin sealing over as growth restarts.

Bare branches also make the work more accurate. We can see crossing and rubbing limbs, weak forks, dead wood and branches growing back into the crown, and decide exactly where each cut should go. In summer the same faults are hidden behind a full canopy, and it is easy to take off too much.

Many fungal diseases are also less active in cold, damp weather than in the warm, humid spells of late summer, so fresh wounds are less likely to be infected. That said, Irish winters are mild and wet, and some trees are exceptions to the rule, which we cover below.

Trees to Leave Alone Until Spring or Summer

Not every tree should be cut in the dormant season. The main exceptions we see in local gardens are these.

• Cherries, plums and other stone fruit. These are prone to silver leaf and bacterial canker, both of which enter through pruning wounds in wet weather. We prune them in dry spells in summer, after fruiting where they crop.
• Birch, maple and walnut. These bleed heavily if cut in late winter, when sap pressure rises ahead of spring. If they need work, we do it in early winter before the sap rises or after the leaves have fully opened.
• Evergreens and conifers. Laurel, holly and most conifers are best pruned in late spring or summer when they are in active growth. Conifers such as Leylandii will not regrow from bare brown wood, so cutting back too hard leaves permanent gaps.
• Spring-flowering trees and shrubs. Magnolia and similar spring-flowering trees have already set next year's flower buds, so winter cutting removes the display. Light shaping is done straight after flowering instead.

Apples and pears are the opposite case. They are pruned in winter by tradition, and the dormant season is the right time to remove dead and crossing wood and open up the centre of the tree for light and air.

Tree Pruning Methods We Use in Winter

Good tree pruning in Dublin gardens is about removing the right branches, not as many as possible. On a typical winter visit we use one or more of the following methods, chosen to suit the species, its age and the space it has.

Deadwood removal

Dead, dying and storm-damaged branches are taken out first. They are easy to identify in winter because they carry no buds, and removing them reduces the risk of falling limbs during strong winter winds.

Crown thinning

Crown thinning removes a proportion of smaller inner branches to let more light and wind through the canopy, without changing the overall size or shape of the tree. It is useful where a tree shades a lawn, patio or neighbouring window.

Crown lifting

Crown lifting removes the lowest branches to give clearance over a path, driveway, lawn or boundary. We take off lower limbs in stages over several years where possible, rather than removing large branches close to the trunk all at once.

Crown reduction

Crown reduction shortens the outer branches to reduce the height or spread of a tree, cutting back to a healthy side branch so that the tree keeps a natural shape. We do not top trees by cutting straight across the main stems, as this leads to weak, crowded regrowth and decay.

Every cut is made just outside the branch collar, the slightly swollen ring where a branch joins the trunk or a larger limb. Cutting flush with the trunk or leaving a long stub both slow healing and make decay more likely.

What to Check Before Any Tree Is Cut

A few points should be settled before work starts on any tree, whatever time of year it is.

1. Confirm who owns the tree. Where branches overhang from a neighbouring garden, talk to your neighbour before anything is done, and agree where the waste will go.
2. Check for planning restrictions. Some trees are covered by a tree preservation order, and trees in an architectural conservation area or at a protected structure can have extra conditions. Your local authority planning section can confirm this.
3. Look for nesting birds. Under the Wildlife Act it is an offence to disturb or damage an active bird's nest at any time of year, and there is a seasonal restriction on cutting hedges and vegetation between 1 March and 31 August, as set out by the National Parks and Wildlife Service guidance on cutting hedgerows. Winter work avoids most of this conflict.
4. Note overhead cables, nearby walls, glasshouses and parked cars, so that branches can be lowered safely rather than dropped.

Large trees, trees near buildings and any work that needs climbing or roping down should be left to a trained tree surgeon. Using a chainsaw from a ladder is particularly dangerous and should never be attempted.

What Affects the Time and Cost of Tree Pruning

Because every tree and garden is different, we price tree pruning after seeing the job. The main factors are listed here.

• The size, species and condition of the tree, and how much work it needs.
• Access to the back garden, for example through the house, a side passage or a lane, and whether a chipper can get close.
• Obstacles under or around the tree, such as sheds, glasshouses, power lines and boundary walls.
• Whether branches need to be roped down in sections rather than dropped.
• The amount of waste, and whether you want it chipped and removed or the wood cut into logs and left on site.
• Whether other work, such as hedge trimming, stump grinding or a full winter tidy, is done on the same visit.

Combining jobs on one visit usually saves time, especially in older terraced gardens with narrow side access. If your garden has become overgrown, our guide to clearing an overgrown garden before landscaping explains how we tackle trees, hedges and stumps in the right order.

Planning Your Winter Tree Pruning in Dublin

Winter tree pruning works best when it is planned. Walk around the garden after the leaves have fallen and note branches that are dead, hanging over paths or roofs, rubbing together or blocking light. Mark any stone fruit or birch trees so that they are kept for a different season, and book the work early, as winter is a busy period for tree work.

Done well, winter tree pruning keeps trees healthy, safe and in proportion with the garden for years. We carry out tree pruning across Dublin and the surrounding areas, and our tree and hedge cutting service covers everything from light crown work to full tree removal and stump grinding. We can also include trees in a regular garden maintenance plan or winter garden service.
