Many gardeners swear by pruning roses (it's one of Monty Don's top plants to prune in September), but Arit Anderson has credited garden neglect as the secret to her blooming rose bush.

"There was one time when I had a very pruned and clipped garden — I would mow the lawn every week. As things got busier, the garden got more neglected," the British garden designer and writer tells Country Living.

"It was upsetting at first, but then I allowed things to meander and decided not to prune the roses every year. Now, I've got this huge prolific rose bush that grows without hardly any human intervention. It might get black spot, but if it does, then I don't stress. It disappears the following year."

Before you rush to hang up your gardening gloves, Arit says we should spend more time trusting, observing and watching our own outdoor space, rather than following rules too closely.

"You will always learn something new by getting things wrong. Asking stupid questions is the rule to follow," she tells us over the phone, "I used to be paranoid about not getting my tulips in on time, but if the weather isn't good, it won't work. I plant them out of season and they always come through.

"Become observant of the timing and what the plant needs. The joy of gardening is that it pushes us to become more observant."

Gardening in step with the seasons is vitally important for a healthy plot. With autumn in the air, Arit says she has a few jobs to tick off.

"I've got a small garden with a lot of trees. This autumn, I'll be looking at what I can cut back as some of them are getting a bit big. Autumn is also a good time to plan perennial moves and see if anything has become too big.

"You may need to divide some of yours. Now is a good time to do this, as you'll see everything in the green. Once things have died back in winter, it will be hard to see how big your plants are. I desperately want to get better at my containers. It's a good idea to plan how you'll get your containers looking good year-round and what bulbs you might put in."

Other autumn jobs Arit recommends are planning your annual flowers, refreshing compost in containers and looking at your soil health.

Don't forget: "Annuals only get one season of interest, so planning them carefully can keep everything looking great."
