Overview: Pruning a cherry tree

  • Summer pruning is suitable for sweet cherries and winter pruning for sour cherries
  • Initial pruning, development pruning, maintenance pruning and rejuvenation pruning each require their own techniques when pruning fruit trees
  • Prune dwarf cherries carefully, as they grow more slowly
  • Prune old cherry trees radically to stimulate new growth and increase yield
  • Pruning cherry trees is important for tree health, safety and aesthetics, among other things

Pruning a cherry tree – when is best?

Timing pruning correctly can help to optimise the health and yield of the cherry tree. While some trees benefit from summer pruning, others should be pruned in autumn or winter.

Please note that there are considerable differences between the sweet cherry (Prunus avium ) and the sourcherry (Prunus cerasus) so the two species are treated and pruned differently – this also affects the timing of pruning.

Here is a tabular overview to help you determine the optimal time to prune depending on the cherry tree species:

Pruning a sweet cherry tree

The ideal time for summer pruning of sweet cherries is after harvest between the beginning of August and the end of September.

Pruning your sweet cherry in the summer will curb the strong growth and promote wound healing.

Pruning a sour cherry tree

If your cherry tree is a sour cherry, you can prune it in autumn or winter, between November and March to be precise.

You can also prune your sour cherry in late winter to lighten the crown and encourage new fruiting wood.

STIHL tip

It is important to note that the best time to prune may also depend on regional weather conditions and specific tree needs. It is always advisable to keep an eye on the health and growth of your tree and make adjustments if necessary when pruning your cherry. If you are unsure about pruning, a suitable course at a local gardening association or adult education centre is certainly a good idea.

Pruning a cherry tree: The right tool and accessories

Special tools are required for pruning cherry trees in order to work precisely and safely. Make sure to use sharp and clean tools to ensure neat cuts and minimise the risk of infection. Here is a list of the most important tools and safety precautions for tree pruning

Overview of pruning techniques 

Properly pruning a cherry tree requires knowledge of various pruning techniques.
Each technique has its own meaning and is used at different times in the life of the tree:

Differences in pruning sweet and sour cherries

Sweet cherries and sour cherries have different growth habits and pruning requirements. It is important to know these differences in order to maintain each tree type optimally and achieve the best yield.

 Sweet cherry details

  • The sweet cherry is a vigorous grower, which is why its growth should be slowed down.
  • Due to their strong apical dominance, sweet cherries grow upwards and form a tall, slender crown. Apical dominance refers to the inhibition of the growth of side shoots by the main shoot.
  • When pruning a sweet cherry, you should proceed with caution so as not to stimulate growth excessively and to minimise the risk of diseases such as gum flow.
  • The sweet cherry only flowers on shoots that are two years old, but then for years afterwards. This means that buds are formed again and again and you should prune back rather discreetly.

Sour cherry details

  • Unlike sweet cherries, sour cherries have bushier growth and form a wider, open crown.
  • The main goal when pruning sour cherries is to obtain a well-ventilated crown that allows light to penetrate. This promotes fruit production and minimises the risk of fungal infections.
  • The sour cherry flowers on shoots that are one year old but then not afterwards. This means that you have to cut back more to stimulate new growth.
  • Sour cherries grow fast – so you should rejuvenate them.
     

By understanding these differences and applying the right pruning techniques, you can ensure that both your sweet and sour cherries grow healthily and produce plenty of fruit.

Overview of differences in pruning sweet and sour cherry trees 

Sweet and sour cherry trees have different properties and therefore also different pruning requirements. The following table provides you with an initial overview of the special considerations you need to take into account.

CharacteristicSweet cherrySour cherry
Type of growthStrongly apical dominant, tends to grow strongly upwardsBushy growth with a more open crown
Main objective of pruningLimit tree size, keep crown open, preserve fruiting woodOpen crown that lets light through, stimulates the formation of new fruiting shoots, prevents decay
Best time to pruneinitial and development pruning in late winter, maintenance and rejuvenation pruning after harvest in summerLate winter before sprouting, maintenance and rejuvenation cutting also possible in summer after harvest
Pruning frequencyRestrained pruning, as the sweet cherry reacts more sensitively to pruning measuresRegular pruning to keep the crown open and allowing light through to prevent decay
Special featuresThe inside of the crown tends to become bare, fruiting moves to the outside, therefore thinning and fruit wood renewal are necessary. Gum flow should not be related to the cut.Tends to form long whip shoots that barely produce fruit, so regular trimming of younger side branches

Special case of pruning dwarf cherries: how to do it right

Dwarf cherries are particularly popular as trees for small gardens or for cultivating terraces in pots due to their compact size. But even though they are smaller, they need targeted care and regular pruning to stay healthy and bear plenty of fruit. 

The best time to do it

The ideal time to prune a dwarf cherry is late winter before the new shoot begins. Light summer pruning after harvesting can also be beneficial to correct the shape and control growth.

Objective of pruning

The main goal when cutting a dwarf cherry is to obtain a balanced, open crown that is well-ventilated and through which sunlight reaches all parts of the tree. 

Procedure

  • When pruning your cherry tree, start by removing all dead, diseased or damaged branches.
  • Shorten excessively long shoots to promote balanced growth.
  • Remove shoots that grow inwards or cross each other in order to create an open crown.
  • For young trees, make sure to establish a good main structure with 3-4 main branches evenly distributed around the trunk.

Special features

As dwarf cherries generally grow more slowly, it is important to be careful when pruning and not to remove too much at once. Pruning too harshly can slow down the growth of the tree.

STIHL tip

By pruning your dwarf cherry regularly and expertly, it will not only stay healthy, but also deliver a rich cherry harvest every year.

Special features: Pruning young and old cherry trees

Depending on the age of the cherry tree, the requirements and techniques of pruning vary. Below you can find out more about the special features and recommendations for pruning a young or old cherry tree:

By understanding these specific requirements and techniques, you can ensure that your cherry tree grows healthily and bears plenty of fruit, regardless of its age.

Radical pruning of old cherry trees

Old cherry trees may appear overaged, bear less fruit or be affected by diseases. In such cases, a radical cut, also known as a “rejuvenation cut”, may be the solution. 

Radical pruning of cherry trees – why?

Radical cherry tree pruning has several advantages:

  • Rejuvenation of the tree: By removing old, diseased or dead branches, new growth can be stimulated.
  • Increased yield: A rejuvenated tree can produce more and better fruit in the years that follow.
  • Diseasecontrol: Removing diseased wood can prevent the spread of diseases and make the tree healthier.

STIHL tip

When you radically prune an old cherry tree, you breathe new life into it. With the right care and attention, your old cherry tree can bloom again and give you many more years of joy.

Post-pruning care

Once you have pruned the cherry tree properly, it is important to give it the right aftercare – so you can ensure health and vitality. A well-maintained tree will heal faster, be more resistant to disease and provide a rich harvest in the following season.

Care tips after cherry tree pruning

  • Wound sealing: Treat larger cuts with a wound sealant. This protects the cherry tree from disease and promotes wound healing.
  • Watering: Make sure that the tree receives enough water after pruning, especially during dry periods. This supports the healing process and growth.
  • Fertilisation: A light spring fertiliser can help the tree recover from pruning and encourage new growth.
  • Disease control: Check the tree regularly for signs of disease or pests, especially where it has been pruned. Early detection and treatment can prevent major problems.
  • Mulching: A layer of mulch around the tree trunk can help keep the soil moist, suppress weeds and protect the tree from extreme temperatures.
  • Regular checks: Check the tree regularly throughout the year to make sure it is recovering well and growing healthily. Remove dead or diseased branches if necessary.
     

When pruning a cherry tree, you should follow these care tips after pruning so that your cherry tree remains healthy and continues to bear plenty of fruit for years to come. It is always advisable to pay attention to the specific needs of your tree and the climatic conditions of your region. Finally, we would like to advise you not to be put off by the many tips on pruning cherry trees – in the end, it's all about your garden and enjoying your own harvest.
