When to prune hedges on the Sunshine Coast

Hedging looks simple from the outside. A pair of shears, a steady hand, and a neat line at the end of the day. In practice, when you cut a hedge matters almost as much as how you cut it. On the Sunshine Coast the growing season is long, the humidity is kind to regrowth, and most hedges will give you 2 or 3 good pruning windows in a year if you read them right.

Here is how we think about it across our gardens from Noosa to Maroochydore.

Late winter is the reset

August is the quiet month for most hedges here. Growth has slowed through winter, the plant is not actively flowering, and the shape is easy to see. A late winter prune is the chance to reset. Cut back hard to the line you want to hold for the year, clean up any inward growth, and feed immediately after to support the flush that is coming.

Species that respond especially well to a late winter reset on the Coast: lilly pilly, murraya, photinia robusta, viburnum, and most native callistemon hedging.

Spring is for shape, not scale

Once you hit September the hedges start running. That is the wrong time to cut hard. A hard spring prune strips the new growth off and you lose the payoff for the winter reset. Instead, spring is for light shaping. A soft once-over every 4 to 6 weeks keeps the hedge tight without punishing it.

If you are going to commit to one extra visit in the year, make it a spring shape. That is what carries the hedge visually through the summer.

Summer needs a gentle hand

Summer hedging is about pace. Growth is fast, rain is unpredictable, and new shoots are soft. A gentle top and sides every 6 to eight weeks is enough. Avoid cutting in the middle of the hottest week. Soft new growth burns in a heatwave, and the hedge can look scorched for a month afterward.

This is also the window where pest and fungal pressure peaks. Every hedge visit in summer is also a plant health visit, whether you book it as one or not.

Autumn is the quiet finisher

A final clean-up in April or May is usually the last big cut of the year. You want the hedge to enter winter tight, healthy, and with enough foliage to protect itself through the cooler months. This is also the right moment for a soil feed. It carries the hedge through winter and sets it up for the late winter reset.

Common mistakes we see

• Hard cuts in December. The most common call we get is in January after a December hard prune burned in the heat. Push those hard resets to August.
• Flat tops, vertical sides. A hedge needs to be slightly narrower at the top than the base so light reaches the lower foliage. Otherwise the bottom goes bare over a few years.
• Feeding without pruning. Feeding a tired hedge without resetting it just accelerates the mess.
• Cutting wet. Pruning foliage wet after a coastal storm invites fungal problems. Let the hedge dry for a day.

A working hedging calendar for the Coast

| Season | Window | What we do | |--------|--------|------------| | Late winter | Aug | Hard reset, feed | | Spring | Sep to Nov | Light shape every 4 to 6 weeks | | Summer | Dec to Feb | Gentle top and sides every 6 to 8 weeks | | Autumn | Mar to May | Final clean, soil feed |

A good hedge is a patient project. It rewards a rhythm far more than a single heroic cut. If your hedging has slipped out of that rhythm and you want it back, we care for hedging across the Coast and hinterland. We are happy to visit and share a schedule that suits the plant, your block, and the way you actually use the garden.
