When to prune a tree in France: the real calendar, species by species

If you want one rule to remember: prune a deciduous tree while it is dormant, that is from November to February, outside frost and outside strong mistral days, and stay away from the period running from 15 March to 31 July, when nests are occupied. For Mediterranean evergreens — olive, holm oak, pine, cypress — the calendar shifts: late winter and early spring suit better, because cold is rarely a problem and the wound closes quickly once sap starts moving.

The rule has exceptions, and the exceptions are what cost money when they are ignored. Plane trees follow their own sanitary precautions because of canker stain. A tree in flower or fruit is treated separately. And a broken limb, or a tree threatening a roof, is not pruned by the calendar: you act as soon as it is safe to do so. The rest of this article goes through each case with the reasoning behind it, so you can judge for yourself whether a date proposed by a professional is a serious one.

A tree is not a shrub. A cut branch leaves a wound that the tree does not repair: it closes it by building callus wood around it, and it walls off the damaged wood so decay cannot spread. The whole pruning calendar follows from this mechanism, and from three moments in the tree’s cycle.

Dormancy: the tree loses nothing

In winter a deciduous tree has no leaves, its reserves are stored in roots and trunk, and sap hardly circulates. A cut at that time costs no productive leaf. For the tree surgeon it is also the season when structure is easiest to read: without foliage you can see dead branches, tight forks and crossing limbs that rub. It is the reference period for anything structural — crown reduction, thinning, removal of large wood.

Sap rise: avoid it for trees that “bleed”

In spring, when sap rises, some species — maple, birch, walnut, vine, mulberry — bleed heavily at the cut. It is not always dangerous for the tree, but it is a loss that weakens it if repeated, and a sweet liquid that draws insects to the wound. These species are therefore cut either in full dormancy or in late spring once the flow has calmed.

Full leaf: a light cut, never a heavy one

In summer the tree is at peak activity. Removing a lot of foliage then deprives it of part of its energy production, exactly when it needs that energy to close its wounds. Conversely, a light pruning — removing water shoots, clearing a facade, lightening a rubbing branch — works very well in summer, and you can see the balance of the crown better. Arborists’ rule of thumb: in summer you remove small wood, in winter you deal with the big wood.

The calendars at the top of search results are written for a temperate climate, sometimes for Quebec: “out of frost, out of sap, before the growth.” They are right there. In the Rhône valley three constraints move them: a short winter where serious frosts are rare, a mistral that dries fresh wounds and breaks tender regrowth, and a summer that regularly exceeds 35 °C. And one constraint that nearly all generic calendars ignore: fire risk, which frames the working season in forest and woodland edges.

This table is a starting point, not a regulation. A year of early drought, a mild winter that brings sap forward by three weeks or a late frost moves the windows. That is why a serious pruning quote gives a period, not a date carved in stone, and why we would rather wait a few days for decent weather than cut on schedule under a 70 km/h wind.

These are the trees we meet most often in gardens, housing estates and farmhouses between Lapalud, Bollène, Pierrelatte and Pont-Saint-Esprit. For each one, the period when a cut is best tolerated, and the most common mistake.

The plane tree, first tree of the landscape, first subject of caution

Rows of plane trees are part of the Rhône valley landscape, from village squares to farmhouse avenues. Canker stain, a disease caused by the fungus Ceratocystis platani, has spread across several departments of southern France, and there is no curative treatment. The fungus enters through wounds, and contaminated pruning tools are among the best-documented vectors. In practice: a plane tree is not pruned lightly, blades and chainsaw are disinfected between two trees, and cuttings are disposed of according to sanitary guidance. If your tree shows foliage that wilts suddenly in summer or reddish stains under the bark, do not prune it: report it to the town hall or to your region’s plant protection services.

Pruning your own tree in your own garden requires, in principle, no authorisation. But several rules overlap, and they are what turn a simple calendar date into a considered decision.

Nests and birds: protection that does not depend on the date

Article L. 411-1 of the French Environment Code prohibits destroying or removing the eggs and nests of protected species, and intentionally disturbing them. It applies to a tree as much as to a hedge, and the individual answers for the cut just as the professional does. Peak nesting runs from March to July: inside a large plane or oak you do not always see the nest, hence the value of watching the tree for a few minutes before climbing.

The three levels of rules that protect nesting apply to trees as to hedges, same law, same caution, same sensitive period. We detail them in our article When to trim a hedge in France: dates, nests and rules.

Burning green waste: prohibited for private individuals

Once the tree is pruned, what do you do with the branches? Open-air burning of green waste is prohibited for private individuals by the circular of 18 November 2011, taken up by the departmental sanitary regulations, and the prefects of Vaucluse, Drôme, Gard and Ardèche also restrict the use of fire during the high-risk season. Branches go to the waste recycling centre, are chipped on site for mulch, or are removed by the professional doing the work. Professionals either remove or chip: the quote should say which.

The fire season: a calendar specific to the south

In summer, prefectoral orders restrict or prohibit, depending on the day’s risk level, access to forest massifs and the use of equipment that can throw sparks. A chainsaw at the edge of the garrigue, a disc on a dry stone wall, a vehicle parked on tall grass: fires also start from work sites. If your tree is on the edge of woodland or scrub, the work is planned outside the red period, and it fits with your brush-clearing duties.

The 50 metres around a building, the owner’s responsibility and the inspections are explained in our article Mandatory brush clearance in France: the 50 metres, the neighbour, the penalties.

Power lines and networks: you do not go near them

A tree whose branches touch or approach an overhead line is never pruned by the owner. Work near networks is subject to a prior declaration procedure and safety distances, and it is the network operator you must contact. Every year serious accidents happen with a pole pruner and a medium-voltage line. It is the absolute limit of what you do yourself.

Protected trees, classified woodland and neighbours

A tree located in a classified woodland area of the local urban plan, in a listed site or within the perimeter of a historic monument cannot be cut or heavily pruned without a prior declaration at the town hall. A remarkable tree registered in the local plan may also be concerned. Before any major work, a phone call to the commune’s planning office settles the question. And if the tree stands on a boundary, not all its branches belong to you: the neighbour cannot cut for you, and you cannot cut on their side.

Planting distances, article 673 of the Civil Code and what is settled amicably are detailed in our article Neighbour’s tree or hedge on the property boundary.

The calendar is for upkeep. It does not apply when the tree has become a risk. In those cases you prune as soon as the situation allows — that is, as soon as working conditions are safe — even if it means adapting the method: a more targeted cut, dismantling in pieces, temporary securing.

• A broken branch still hanging in the crown, which can fall at any moment onto a roof, a vehicle or a path.
• A tree destabilised after a violent wind or hail: leaning trunk, lifted root plate, split at the fork. In that case do not go near the base.
• Branches touching a roof, a gutter or a chimney, damaging the covering or encouraging leaks.
• Significant dead wood: a large leafless branch in the middle of the growing season is generally a dead branch, therefore brittle.
• Signs of a disease or insect attack that is progressing fast: fungi at the base, black seepage, foliage yellowing on one side only.

An emergency is also a tree whose roots or trunk have already suffered too much to be saved. In that case pruning gives way to felling, with stump removal if the spot is to be reused. It is a decision made on site, after looking at the base, the fork and the wood: we never fell on principle, and we do not keep a dangerous tree out of sentiment.

When the tree can no longer be saved, felling is done by sectional dismantling if access is narrow, with stump removal if the spot is to be reused: Tree felling and stump removal.

When a tree is badly pruned, the defect does not show straight away: the tree grows back, it even puts on a fine flush the following year, and it is three or four years later that a badly formed branch breaks or a trunk rots from the inside. These are the mistakes we see most often on trees we are asked to rework.

Topping: the false good idea

Cutting the head off a tree to “bring it back down” is the most widespread practice, and the most harmful. The tree reacts by producing a mass of shoots at the cuts. These shoots are poorly attached, grow fast, and within a few years rebuild a volume more fragile than the one you removed. The wide wounds, meanwhile, let water and fungi in. If a tree is too tall for its spot, the right answer is a crown reduction: each branch is shortened back to a lateral branch of sufficient diameter, respecting the natural habit.

Cutting flush with the trunk, or too long

A branch is cut just outside the swelling at its base, the branch collar. Closer, you wound the trunk and slow the closing of the wound. Further out, you leave a stub that dries and rots. A heavy branch is cut in three steps: a first notch from below about thirty centimetres from the trunk, a cut from above a little further out to release the branch, then the final cut at the collar. This method prevents the weight of the branch tearing the bark off the trunk as it falls.

1. 1Notch from below, about thirty centimetres from the trunk, through a third of the branch thickness.
2. 2Cut from above, a little further out, to release the branch without tearing the bark.
3. 3Clean cut of the remaining stub, just outside the collar, without damaging the swelling.
4. 4Branches removed or chipped on site before moving to the next tree, tools cleaned if it is a plane tree.

Wound paint: useless, sometimes harmful

The idea that wounds must be painted with a healing paste was long widespread. Arboricultural work shows it does not speed healing, and that it can trap moisture in the wound. A tree protects itself, provided the cut is clean and in the right place. The product only makes sense on certain fruit trees or for large diameters, on a professional’s advice.

Climbing without method: the mistake that hurts people

Most pruning accidents involve private individuals on a ladder set on soft ground, with a chainsaw at arm’s length. A ladder is not a workstation. Pruning above three metres with a powered saw is a professional job, with harness, ropes or an aerial platform, a second operator on the ground and a marked drop zone.

Not everything has to be delegated. A homeowner with secateurs, a pole pruner or a pruning saw can perfectly well look after small subjects, from the ground or from a stable stepladder. The right criterion is not gardening skill, it is height, branch diameter and the proximity of everything you do not want to touch.

For a mature tree, a crown reduction or a roof clearance, we work on a free quote, with branches removed or chipped. The details of the service are on our page Tree pruning in Lapalud and northern Vaucluse.

A pruning quote is built on precise criteria: the height and diameter of the tree, access (a tree in an enclosed garden costs more to work than one along a drive), the method (climbing, platform, dismantling) and what happens to the waste. We do not publish a price grid: a tree is looked at on site, and a figure given over the phone without seeing it is a figure that will be revised. We come, we look, and we give you a written quote that details what is included.

Some garden upkeep expenses give right to a tax credit, provided the provider meets certain conditions. We explain the scheme and its limits in our article The French gardening tax credit: ceiling, covered work and approval.

We are a sole-trader business: it is Josué Poulain who comes, looks at the tree, writes the quote and does the work. There is no salesperson promising a date and a crew keeping another. This is the usual sequence, from the first visit to the last branch removed.

1. 1Free visit on site, looking at the tree, its surroundings (lines, roofs, neighbours, access) and the season.
2. 2Choice of the working period: straight away if the tree demands it, or within the calendar window above if it can wait.
3. 3Written quote stating the method, what is cut, what happens to waste and any special precautions (plane tree, nest, line).
4. 4The work: marked drop zone, clean cuts at the collar, protection of whatever lies below.
5. 5Branches removed or chipped, ground tidied, and advice on upkeep for the following years.

We work in Lapalud, Bollène, Mondragon, Mornas, Pierrelatte, Pont-Saint-Esprit, Bourg-Saint-Andéol and within about 30 kilometres of Lapalud, across four departments: Vaucluse, Drôme, Gard and Ardèche. To find out whether your commune is covered, see our service area page, or simply call.
