The Spring Window: Six Weeks When Everything Digs Easily
Between the last of the rain and the first hot northerly, Western Australia has a short stretch when the ground is soft, the days are mild and the fire rules haven't started. Use it well.
Ask any Perth landscaper when they are busiest and the answer is the same: September and October. The reasons are all in the ground.
Why spring is different
- Moisture without water. The winter rain has soaked in but the water table is falling. Sand has apparent cohesion, clay is plastic rather than sticky, gravel is firm rather than concrete.
- Mild temperatures. Machines and operators both work better at 22 degrees than 38.
- No fire restrictions yet. Restricted burning periods and firebreak deadlines mostly start in November, so machine work in grass and bush has no bans to dodge.
- Grass is green. Slashing and firebreak cutting are easy while grass is soft; cured grass in November is harder on brush cutters and a fire risk in itself.
The window is short. By late October a hot northerly can turn Hills clay to brick in a week, and by November the plain is dry and the fire rules are in force.
What to prioritise
Hills and gravel country
Anything that involves cutting into laterite: footings, shed pads, driveway cuts, fence strainers. In summer the same jobs need a ripper and twice the time.
Firebreaks and fuel reduction
Cut breaks and slash low-fuel zones in September and October, then touch them up after the deadline. Regrowth after spring rain is the reason breaks fail inspection. A skid steer with a brush cutter does it in an afternoon.
Landscaping
Lawn, garden beds, reticulation and paving prep all go in now so they establish before summer heat. An RS06 moves the sand and mulch; an R18 PRO does the retaining walls and drainage.
Retaining walls and soakwells
The sand holds a face and the water table is falling. Both jobs are easier now than in either winter or high summer.
Lining it up
Spring is also when machines sell fastest and delivery lead times stretch. If you plan to buy for spring work, decide in winter. If you plan to hire, book early; the good machines are gone by the second week of September.
