Gardeners warned it's the 'worst time' for common task that leaves trees 'vulnerable'

As autumn approaches, many gardeners are keen to get their trees ready for winter. However, one expert has warned against doing one common task at this time of year

As the autumn season draws near, many green-fingered enthusiasts may be tempted to give their trees a tidy up. However, one gardening expert has issued a warning about a particular task.

While it might seem like a good idea to prepare your fruit trees for the winter, the results could actually do more harm than good. Incorrect pruning methods can cause lasting damage and leave your trees vulnerable to various threats.

With chillier weather on the way, it's important to understand the fine line between tree care and seasonal changes. "Pruning in the fall is the worst time because the wounds won't heal properly, leaving the tree vulnerable," warns Susan Poizner, founder of Orchard People and an ISA Certified Arborist, reports the Express.

"Instead of sealing up, the cuts stay open, inviting pests and diseases. Fall pruning can also encourage tender new growth, which is easily damaged by frost."

During the colder months, trees naturally enter a dormant phase that is crucial for their survival. Disturbing them during this period can lead to long-term health and productivity problems.

If you're thinking about pruning your fruit trees this autumn, Poizner advises waiting until late winter. He suggests: "Prune in late winter to spur strong, vigorous growth, especially for young trees."

"If your goal is to slow the tree's growth, early to mid-summer pruning is ideal, as the tree is focused on fruit production rather than new shoots."

Gardeners are being advised to hold off on certain autumnal tasks, as waiting for more appropriate times can prevent frost damage and put your trees in the best position to flourish.

Experts warn against fertilising during this season, explaining that encouraging new growth now can backfire. "Tender new shoots won't harden off before winter and can break during a hard frost," cautioned a gardening aficionado.
