Plant guides

Everything we know about the hedges in your street.

Six plants make up most of the hedging in the Sutherland Shire. Each one wants to be handled differently, and knowing which is which is most of our job. We’ve written down what we actually tell clients at the gate — how fast it grows, how often it needs cutting, whether it survives a hard reduction, and what it’s telling you when it goes brown.

No sign-ups, no email capture. If it saves you a call-out, good.

The one rule that applies to all of them

A hedge should be slightly wider at the base than at the top.

This is the single most common reason a hedge goes bare at the bottom, and it has nothing to do with the species, the soil or the fertiliser. If the sides are cut straight up — or worse, leaning in — the top of the hedge shades its own base. The lower foliage gets no light, gives up, and drops off.

Cut with a slight taper and light reaches the whole face. The hedge stays green right to the ground. It is a small change in how the cut is made and it is the difference between a hedge that lasts and one that slowly hollows out from the bottom up.

Hedge profile: straight-sided versus tapered Two hedge cross-sections. The straight-sided hedge shades its own base and goes bare at the bottom. The tapered hedge, cut slightly wider at the base than the top, lets light reach the lower foliage and stays green to the ground. STRAIGHT SIDES Top shades the bottom. Base goes bare and stays bare. TAPERED (BATTER) Light reaches the whole face. Green right down to the ground.
The taper is often called a batter. On a fast grower like lilly pilly or viburnum a bare base can be recovered with a hard reduction. On a slow grower like box, correcting it takes years — which is why the shape matters most on the plants that are least forgiving.
The other rule

A trim and a reduction are two different jobs.

Every guide here distinguishes between the two, because it is the thing that moves the price more than anything else. A trim takes a hedge back to a shape it already has. A reduction resets a hedge that has got away — usually cutting into bare wood, and usually looking confronting for a few weeks before it thickens up.

Whether your plant survives that second job depends entirely on the species. Lilly pilly, murraya and viburnum reshoot from old wood happily. Box does too, but so slowly that a hard cut leaves you bare for a year or more. Each guide says which.
