Pruning is just one of the many gardening jobs to tackle in September to keep plants healthy and in bloom, as the seasons shift from summer to autumn.

Even if you’ve not ticked off your August pruning checklist, there’s still a chance to catch up on those gardening duties.

Bryan Clayton, CEO of GreenPal and a seasoned green-fingered guru, has released a guide of five plants that are ripe for pruning this month along with top tips on how best to do it.

He unpacked the mystery of pruning: “Pruning can seem daunting, but it doesn't have to be. Basic pruning shears for smaller branches and loppers for branches more than half an inch in diameter should do the trick.”

1. Fruit trees

If your fruit trees are beginning to look somewhat wilder than you might like, Bryan claims that the “secret” to managing them is quite simple - prune in “early September” before the frost makes an appearance.

He instructed: “Remove any dead wood and thin out crowded branches to allow better air circulation and light penetration.”

2. Hydrangeas 

Gardeners are often left scratching their heads when their hydrangeas don't bloom as expected. 

The gardening expert has cautioned that when it comes to pruning hydrangeas, one must “be careful”.

Bryan advised: “Only prune the ones that bloom on new wood, like the panicle and smooth hydrangeas. Cut back the spent blooms and about one-third of the height.”

3. Rose bushes 

Roses remaining radiant requires timely trims, and according to our expert, now's the moment to make that cut.

Bryan explained: “September is a great time to give them a light pruning. Snip off any dead or faded blooms about a quarter-inch above a five-leaflet leaf.”

This sage snippet of advice is all about redirecting energy into fresh growth and setting up the shrub for the colder months ahead.

4. Summer-flowering shrubs

It's time to get snipping at those summer-flowering shrubs such as spirea this month. Pruning these beauties now means “more blooms next year”.

Once they've finished showing off their flowers, give them a good trim to “shape them up and encourage new and healthier growth”.

5. Perennial herbs

Now’s the moment for garden enthusiasts to start pruning perennial herbs like sage and rosemary to promote fresh sprouts.

Pruning these herbs early in autumn can "stimulate a burst of new growth" that will “last until the first frost”.

Bryan recommended: “Clip back about a third of the branches, but avoid cutting into the woody parts of the plant.”
