Autumn to early winter

Expert insight into the best time to prune a rowan tree; why rowan tree pruning is important, and how to identify common rowan tree diseases.

The rowan tree, or Sorbus aucuparia to give it its Latin name, is a UK native species. Rowan is also known as the mountain ash due to the fact it is able to survive high altitudes, and because its pinnate leaves are very similar to those of the common ash. However, the two are not related.

Other names for the rowan tree are witch wiggin, keirn and cuirn. The tree is deciduous and will grow up to 15 metres in height, and can live for up to 200 years. In spring, the rowan tree will blossom with beautiful white flowers, followed by stunning bursts of red berries in late summer to early autumn.

The name witch wiggin came about as the rowan tree was once upon a time planted by homeowners in order to protect against witches; in Ireland it was grown to ward off evil spirits and in Wales the rowan tree was a popular sight in churchyards. In Scotland, the felling of a rowan tree was forbidden. The bright red berries were considered the best possible colour to fight evil, which is why the rowan tree has been associated with witches and magic for many years and was in fact known in Celtic as the wizards’ tree.

Why prune a rowan tree?

The abundant fruit of the rowan tree can weigh heavy on its branches, so it’s vital to regularly prune the tree in order to encourage a strong framework to support it. Without a strong framework, you will find branches regularly breaking off under the strain. This is both dangerous and not healthy for the tree.

Regular pruning generally promotes the good health of a tree by allowing air and sunlight to circulate. It also allows the wind to pass through easily, which prevents storm damage.

The rowan tree also benefits from having damaged or crossing branches removed so as to leave a clear trunk up to two metres in height.

When is the best time for rowan tree pruning?

When you prune a tree, it will naturally bleed sap if it is actively growing. This is why it’s always best practice to avoid pruning during the growing season. In the case of the rowan tree, autumn to early winter is considered the best time.

If you are pruning to remove deadwood for safety reasons, you can proceed at any time if there is an impending risk of personal injury or property damage.

What to look for when pruning a rowan tree

The rowan tree can suffer from fireblight, and may be susceptible to silver leaf disease. Look out for wilting blossoms, cankers and oozing slime; or in the case of silver leaf disease, silvery leaves and branch dieback. Aphids, blister mites and sawflies can also be an issue.

Tree Preservation Orders and Rowan Tree Pruning

You should never proceed with any tree work including rowan tree pruning unless you are satisfied that there is not a Tree Preservation Order (TPO) in place. If there is, will need permission before you go ahead. This can take up to eight weeks to come through. What’s more, if the tree is situated in a conservation area, permission must be gained before commencing works of any kind.

Expert insight into the best time to prune a sycamore tree; why sycamore tree pruning is important, and how to identify common sycamore tree diseases.

The sycamore tree belongs to the maple family. Of the Latin Acer pseudoplatanus, the sycamore is a large broadleaf deciduous tree that is native to southern, eastern and central parts of Europe. It is thought to have come to the United Kingdom during the Middle Ages, and is now considered a naturalised species, highly prevalent across the country due to the ability of its winged seeds to spread and reseed with ease.

The domed canopy of the sycamore tree is particularly striking, and the tree will grow to heights of up to 35 metres and can live more than 400 years. You’ll find it along avenues and in gardens and parks, creating much called for shade.

Why prune a sycamore tree?

The sycamore tree has a tendency to grow into an odd shape as it matures, often with drooping branches and extreme angles. Sometimes the branches will wrap around the tree. Pruning is essential to manage the tree’s shape, and it will also promote new growth.

Sycamore trees benefit from pollarding to keep them at an ideal height, particularly if they are growing along avenues and on public land. Pollarding also helps create a nicely rounded canopy, but this needs to start as a continuous process from the tree’s early days and then carry on every year for shape and size maintenance.

Sycamore pollarding or crown reduction is particularly useful when light is being blocked and there is the risk of neighbour disputes arising.

When is the best time for sycamore tree pruning?

Because sycamore sap is at its most prevalent during the spring, it is important to refrain from pruning this tree during this season as it could lead to fatal consequences. Bleeding sap attracts bugs, which bring with them disease.

If you are pruning a sycamore tree simply to remove unwanted branches, it is best to undertake the work in June. However, if you are looking to heavily prune the tree, you should leave it until later in the year, preferably between October and December. Proceed with caution though, because you need to avoid damaging the collars of the branches by keeping the pruning flush with them. Remember, open wounds are potential points of disease ingress, so all pruning should work to minimise this. If in doubt, consult a qualified tree surgeon.

You will also need to remove dead wood on a regular basis, and crown thinning is also a wise move so as to allow light and air to penetrate, which is vital for the prolonged health of the tree. Wherever possible, carry out this work during the month of June.

A tree surgeon will inspect the tree and work out whether certain limbs will be able to carry the weight of the leaves. If they aren’t, then they will remove them, because they will become unsafe and could stress the tree as a result.

What to look for during sycamore tree pruning

The sycamore tree is prone to sooty bark (cryptostroma corticale). Where the weather has been continuously hot, sooty bark will cause partial or total crown wilting which can eventually be fatal.

Verticillium wilt is a fungal disease that gets into the tree through the roots. It causes wilting, yellowing leaves and dieback. Phytophthora root rot causes yellow, sparse or wilting foliage together with branch dieback.

Leaf spot and tar spot are also common issues, although these aren’t considered too dangerous. Bark stripping by grey squirrels is another low key problem.

Pest wise, the horse chestnut scale insect is one of the main issues, although it doesn’t tend to affect the trees unless they have been deprived of nutrients or water. Look out for white circular egg masses partially covered by brown shells on trunks and larger branches. These will appear in early summer and are caused by a sap-sucking insect.

Tree Preservation Orders

You should never go ahead with any tree work, including sycamore tree pruning, before learning whether there is a Tree Preservation Order (TPO) in place. If so, you have to seek permission for the works. This will usually take up to eight weeks to materialise. Furthermore, if the tree is situated in a conservation area, permission must be obtained before starting works of any kind.
