Late October is the right time to assess storm risks across a macadamia orchard. As spring moves towards the wetter, more storm-prone part of the year, heavy rain, strong winds, hail and lightning can quickly affect trees, access, infrastructure and crop potential.
At Allen Agri Consulting, we encourage orchard owners to act before a weather warning appears. A property-specific agricultural risk assessment in NSW helps you identify weak points early, set maintenance priorities and keep clear records for recovery planning if a storm does cause damage.
Protect Orchard Value Before Storms Arrive
Storm preparation is more than a quick check of drains and shed doors. Every orchard responds differently to wet weather and wind, depending on its slopes, soil types, tree age, row direction, drainage capacity and past storm exposure.
Reactive clean-up is often harder when access tracks are damaged, water is pooling around trees or fallen limbs are blocking machinery. A planned review gives you a clearer order of work before conditions become difficult.
Documented observations also support better decisions. Keeping notes, photographs and maintenance records can help you plan contractor work, discuss insurance matters and prepare practical post-storm reports. Rather than relying on memory after an event, you have a useful picture of the orchard’s condition beforehand.
Map Storm Exposure Across Every Orchard Block
A whole-property view matters because one block may handle rain well while another becomes exposed to runoff, wind or poor access. Ridges, sheltered gullies, steep slopes and low areas can all behave differently during the same storm.
We recommend mapping the areas most likely to be affected first, including:
- Wind-exposed ridgelines, row ends and blocks with limited shelter
- Low points, overland flow paths, culverts, drains and creek crossings
- Erosion-prone slopes where water may move soil, mulch or debris
- Farm roads, bridges, loading areas and tracks that could become unsafe
- Pump sites, power equipment, sheds and chemical storage areas
Wind exposure deserves close attention. Check the condition of windbreaks, look for leaning trees and note mature canopies with large limbs that may be prone to breakage. Trees with prior storm damage or poor branch structure may need assessment before high winds arrive.
An agricultural risk assessment in NSW should also identify which infrastructure needs protection first. If a severe weather forecast is issued, knowing the location of vulnerable assets can help you make calm, timely decisions instead of rushing around the property at the last minute.
Inspect Trees, Soils and Drainage Before Heavy Rain
Regular orchard inspections are a practical part of professional macadamia farm management. They are not only for storm season, but the period before summer weather becomes more unsettled is a sensible time to focus on known trouble spots.
Start with tree structure and canopy condition. We look for deadwood, crossing limbs, weak branch unions, signs of stress and damage left from earlier weather events. Where branches could affect workers, machinery, buildings or neighbouring trees, pruning or arboricultural advice may be needed.
Soil condition also tells an important story. Exposed roots, erosion scars, compacted traffic zones and water that sits on the surface can all signal that heavy rain may cause bigger problems. On sloping orchards, fast-moving runoff can remove soil and make tracks difficult to use.
Drainage checks should include table drains, diversion banks, culverts and sediment controls. Clear flow paths are particularly important where runoff may carry mulch or debris into drains. We also recommend noting places where water pools around tree bases, as long periods of wet soil can affect root-zone conditions and delay machinery access.
Align Irrigation with Northern NSW Conditions
Irrigation planning should reflect the conditions on your own Northern NSW property. Approaches used in Queensland macadamia orchards should not simply be transferred across the border, as rainfall patterns, soil types, water availability, storage capacity and orchard systems can differ.
Before wet weather, we recommend reviewing irrigation against current site conditions rather than relying on a fixed routine. Rainfall records, soil moisture observations, weather forecasts and system checks can help avoid unnecessary watering when soils are already approaching saturation.
A pre-storm irrigation review can include:
- Checking pumps, filters, lines, valves and emitters for faults
- Inspecting electrical connections and drainage around pump stations
- Securing vulnerable components where wind or floodwater may reach them
- Confirming that the system can be safely isolated during lightning or power interruptions
- Planning a post-storm inspection before normal irrigation resumes
After significant rain, inspect for washed-out fittings, blocked emitters, damaged lines and changes in soil moisture. The right time to restart irrigation depends on what you find across each block, not what the calendar says.
Safeguard Workers, Equipment and Records
Storm planning needs to protect people and keep the farm operating as safely as possible. Clear responsibilities help everyone know what to do when there is lightning, high wind, flooding or damaged access.
Worker procedures should cover when to stop work, how to communicate, where safe shelter is located and which places are off limits. Creek crossings, unstable slopes, damaged tree zones and flood-prone tracks may need to be restricted until conditions improve.
Equipment and chemical storage deserve the same attention. Where practical, machinery can be moved away from areas likely to flood. Loose materials should be secured, shed roofs checked and repair supplies stored where they remain accessible without creating a safety risk. Chemical storage should be protected from water entry and kept compliant with applicable requirements.
Good records are often overlooked until they are needed. Photograph high-risk areas before storm season, retain maintenance notes and document damage after an event. These records can support insurance discussions, recovery reporting, property assessments and decisions about what needs attention first.
Put Your Storm Plan Into Action Now
The most useful storm plans are specific to the property, updated regularly and based on what is happening in the orchard. Before the season becomes more severe, map high-risk blocks, inspect drainage and access, review tree condition, check irrigation equipment and confirm worker safety procedures.
A clear agricultural risk assessment in NSW gives you a practical starting point when weather conditions change quickly. By documenting existing conditions and addressing known weak points early, you can protect orchard value and make post-storm recovery more organised if damage occurs.
