Tree lopping and crown reduction in California Gully

Lopping is what most people ask for when a California Gully tree gets too big for its block. What we actually do is a crown reduction to AS 4373, and this page shows why that matters over the next ten years.

Arborist climbing and reducing a large tree canopy, the way TB'S Trees approaches tree lopping in California Gully

Ask around the older streets of California Gully and you will find plenty of trees that were "lopped" twenty or thirty years ago: sugar gums cut flat at gutter height, peppercorns with a fist of regrowth on every stub, pines with a dead pole up the middle. They are why TB'S Trees does tree lopping in California Gully as a proper crown reduction rather than a topping job. Below: what the suburb does to its trees, then a side-by-side of a lopped tree and a reduced tree after one, three and ten years.

Quick answer

TB'S Trees provides tree lopping in California Gully (3556) as crown reduction to Australian Standard AS 4373, carried out by qualified, insured Bendigo arborists. Call 0498 609 887 for a free quote and an honest opinion on whether the tree needs it.

What California Gully's ground and weather do to a tree

The suburb sits on some of the most worked-over ground in Bendigo. Gold was found here in 1852 and the mines around Eaglehawk Road kept going into the 1920s, so what looks like a garden bed is often a shallow skin of topsoil over quartz rubble and mullock. Trees rooted in it grow slowly, hold less water through summer, and put on dense, heavy wood. Once a sugar gum or a box reaches the height of the powerlines, the crown is carrying a lot of weight on a root plate that never had deep, soft ground to spread into.

Block size adds to the problem. On a six-hundred-square-metre cottage block there is no such thing as a tree in the middle of the yard. It is against the fence, over the shed, or over the neighbour's roof. So the request we hear most is "can you take a few metres off the top?", usually after a hot north wind has dropped a limb or the tree has grown into the service line. The instinct is right; the method is what matters.

One more local factor: many older trees in California Gully have already been topped once, and have spent decades growing a new crown out of weakly attached shoots around rotting stubs. Those regrowth heads are the limbs that fail in storms, and they are what we most often end up reducing or removing today.

Lopping versus crown reduction: the same tree over ten years

The table below is what we would expect from a typical mature sugar gum or box on a California Gully block, treated the two different ways.

Topping compared with crown reduction on a California Gully tree
Time after the workLopped (topped)Crown reduced to AS 4373
After one year A fist of vertical shoots at every cut, bare stubs above them, decay already moving into the exposed heartwood. Shade gone; yard hotter, lawn scorched. Roughly a fifth smaller but the same shape. Cuts back to side branches have begun to seal. Shade kept; the canopy is thinner and lets more light through.
After three years Regrowth two to three metres long, thin and poorly attached, often back over the wires or the gutter. Rot working down the stubs. Needs lopping again; the cycle has started. Steady growth spread through the whole crown rather than bunched at the cuts. Structure sound. Usually nothing needed yet beyond a light maintenance prune.
After ten years Several heavy heads on decayed stubs. High risk of a whole head tearing out in a storm. Often unsafe to climb; removal is frequently the only sensible option left. Still fits its space with a reduction every few years. Wood sound, value on the block kept, and the tree can be climbed and worked safely for decades.

How a reduction to AS 4373 is done

AS 4373 is the Australian Standard for pruning amenity trees. For a reduction it comes down to a few rules: every cut goes back to a live side branch at least a third the diameter of the piece removed, so the tree keeps a growing point and the wound stays small; height and spread come back in proportion so the tree still looks like a tree; and no more than about a quarter of the live crown comes off at once, because a eucalypt stripped harder than that in a Bendigo summer responds with exactly the shoot growth we are trying to avoid. Pines cannot be cut back into bare wood at all, so a reduction on a radiata is limited to what can be taken back to green growth.

What a crown reduction looks like on a California Gully block

A typical job is a sugar gum on the fence line of a weatherboard cottage a few streets off Eaglehawk Road, planted decades ago as a windbreak and now well above the mains. The owner wants it "lopped" because a limb came down in the last northerly. We climb it, because the side access is a metre wide. Working from the top down, the leader and the longest laterals are reduced back to side branches, the wire side is brought in a little harder for clearance, and dead wood is stripped out as we go. The pieces are lowered on a rope onto the driveway and chipped. The tree finishes a few metres shorter, noticeably lighter on the roof side, and still looks like a sugar gum.

If the same tree had already been topped and was carrying rotten-stubbed regrowth, we would tell you honestly whether reducing it again is worth it or whether tree removal in California Gully is the better spend. Keeping a reduced tree in shape is a light job every few years, covered on our tree pruning in California Gully page.

California Gully tree lopping questions

Often, yes. We can thin the regrowth on each stub down to the strongest one or two shoots and reduce those back to a sensible height, which is called restoration pruning. It takes a couple of rounds over several years. If the stubs are badly decayed we will say so, because at that point the tree may not be worth saving.
It reduces the risk a lot, because the long, heavy end-weight that snaps in a gust is exactly what a reduction takes off. It does not make a box or a gum drop-proof; they shed limbs as a survival tactic in drought. Regular deadwooding after the reduction keeps the risk low.
As a rule, not more than about a quarter of the live crown in one visit. Take more and a eucalypt will throw out masses of weak shoots, and a pine will simply die back. If the tree needs to be much smaller than that, it is usually the wrong tree for the spot and we will say so.
Reductions done to the standard are generally treated as pruning, but if your block sits under a heritage or vegetation overlay in the City of Greater Bendigo planning scheme, some works can still need council approval. We check the address before we quote and tell you if that applies.
The part of the tree near the street mains has to be handled under the rules for working near live lines, and the service line to the house may need to be disconnected while we work. We assess that at the quote and arrange what is needed; you do not have to organise anything with Powercor yourself.
