We all know that pruning is a must when it comes to tree and shrub care. Gardeners looking for healthy growth and shape know the importance of the secateurs.
As autumn rolls around, you might be thinking, ‘What should I be cutting back?’ Will my trees be damaged come spring time if I cut them back?’
Well fear not, our essential autumn pruning guide will shed some light on exactly what you should prune this autumn. You’ll learn how to protect your plants so that they’re ready to thrive in spring.
Why Autumn Pruning is Important
Pruning in autumn will help get your trees and shrubs ready for the dormancy period over winter.
You can reduce the risk of infection during the colder months by cutting back dead or diseased branches. This technique can also help plants conserve energy by redirecting it from weak growth to healthier areas. By pruning, you can also prevent breakage on overgrown branches when the heavy winter winds hit.
However, it’s best to approach autumn pruning with a healthy dose of caution. Pruning too much, too early, or trimming the wrong species may harm your plants. This can leave them vulnerable to frost or may disrupt their growth cycles.
What You Should Prune in Autumn
Many trees and shrubs are perfect for autumn pruning. These species tend to be hardy and pruning will help them manage the upcoming winter conditions.
Deciduous Trees
Deciduous trees, which shed their leaves during autumn, are generally good options for pruning after leaf fall. Once the leaves have dropped, you’ll be able to see the true structure of the tree. This means that you’ll be able to easily spot weak or crossing branches.
What to Prune: Get rid of damaged, dead or diseased branches. We also recommend thinning out crossing branches. This technique will allow more light and air to reach the tree at its core. You can also take the opportunity to cut back branches that have started growing at awkward angles or growing over each other.
Examples: After they’ve lost their leaves, Oak, Beech, and Maple can be pruned in autumn.
Fruit Trees
Lots of fruit trees will benefit from autumn pruning, especially trees that have finished fruiting. Pruning them in autumn helps fruit trees retain their shape, control their size, and supports good fruit produce next year.
What to Prune: Make sure to remove dead or diseased wood. Trim back branches that are growing inwards. This will help to open up the canopy, allowing more light and air to circulate.
Examples: Apple and Pear trees are absolutely fine to prune in late autumn after you’ve harvested the fruit.
Summer-Flowering Shrubs
Some summer-flowering shrubs like Buddleja and Lavender can be pruned in autumn after their blooms have faded. Pruning in autumn helps shape the shrub for spring growth. Removing spent flowers will also help for the upcoming year.
What to Prune: Trim the flowering stems to prevent the shrub from becoming leggy. For Lavender, aim to cut back by a third. However, we’d advise avoiding cutting into old wood as it might not regrow.
Examples: Buddleja, Lavender, and Hydrangeas (cut back spent flower heads but leave old stems for protection).
Hedges
Autumn is the perfect time to give your hedges one last tidy-up before winter hits. Giving them a trim in autumn means they will maintain their shape and won’t become overgrown.
What to Prune: Make sure to cut back new growth to maintain a tidy, compact shape. However, don’t cut into old wood, especially with species like Box or Yew.
Examples: Box, Yew, and Privet hedges.
Autumn Pruning Tips
-
Use Sharp Tools: Make sure you’re using clean, sharp pruning saws or secateurs to make clean cuts. This will help your trees heal faster and reduce the risk of infection.
-
Cut at the Right Angle: When you’re pruning branches, make cuts at a slight angle, just above a bud or node. This will reduce the risk of rot because water will run off.
- Don’t Over-Prune: We advise against heavy pruning in autumn, as this can cause new growth that won’t have time to harden off before winter.
Final Thoughts
Pruning in autumn is a great way to prepare many of your trees and shrubs for winter. Plus it can also help to ensure healthy growth for next spring. However, it’s important to know which plants can handle an autumn trim.
Happy pruning
