A North West garden in October is a wind tunnel. The sun is hot, the soil is dry, and the wind off the Kalahari sand lifts everything that isn't tied down. Plastic bags, leaves, the neighbour's newspaper, dust from the construction site two streets over, all of it ends up in your garden. The plant damage is the obvious one (broken branches, scorched leaves), but the dust is the slow one. It coats everything, smothers the lawn, and fills the air you breathe.
The North West gardener fights two enemies: the wind and the dust. A good garden in the province handles both. A few habits, a few plants, and a bit of routine cleaning make the difference.
What the Wind Does
The North West wind in spring (September to November) is relentless. Rustenburg, Mahikeng, Klerksdorp, the whole province gets hot dry winds that strip moisture from leaves, sand-blast tender growth, and deposit dust in every corner.
The damage:
- Broken branches. The brittle winter wood snaps in the gusts.
- Scorched leaves. The wind strips the moisture faster than the roots can replace it.
- Wind-thrown trees. The newly planted ones, with shallow root systems.
- Wilted annuals. The bedding plants that were doing fine yesterday are flat today.
- Pests. The dust masks the beneficial insects. The aphids multiply unchecked.
The fix is partly plant choice and partly structure. The plant choices that handle the wind are indigenous. The structures that help are windbreaks.
Windbreaks That Work
A solid wall blocks the wind, but it creates turbulence on the other side. A permeable windbreak (about 50% open) is much more effective. The wind filters through, losing speed without creating the destructive eddies.
The options:
- A hedge. The classic. Plant a row of evergreen, wind-tolerant shrubs. The carissa, the wild olive, the wild pear. They take a few years to fill in, but they last decades.
- A fence with a windbreak fabric. The cheaper quick fix. The fabric attaches to the fence, blocks 50% of the wind. Replace every 5 to 7 years.
- A trellis with climbers. Star jasmine, granadilla, bougainvillea. The plant takes a year to establish, then it's a green windbreak.
- A row of trees. The long-term solution. The wild fig, the white stinkwood, the wild peach. Plant 5 to 10 metres apart, depending on the mature size.
Place the windbreak on the prevailing wind side (usually the north-west in the North West). A single row 5 to 10 metres from the house or garden gives the best shelter.
Raking from Perimeter to Center
The wind blows debris into the corners. Leaves pile against the fence, against the house, in the gutters. Raking from the outside in is the most efficient pattern:
- Start at the edges. The fence line, the house wall, the corners.
- Pull the debris toward the centre. A pile in the middle of the lawn or the bed.
- Bag or compost. The leaves from the edges have the dust on them. Compost them slowly or bin them.
The pattern saves time. Raking the other way (centre out) means you're constantly moving the same pile. Edge-in is one direction, one job.
A few raking tips:
- A leaf rake for the leaves, a stiff broom for the paving. Two tools, two jobs.
- Damp leaves are heavier and easier to collect. A light watering before raking helps.
- A leaf blower is fast but loud. The neighbours notice. Use it for the big areas, the rake for the detail.
- A wheelbarrow or a tarp next to the pile. Saves on the back.
Soil Protection From Wind
The dust on the surface is the visible problem. The bigger problem is the wind erosion of the topsoil. The topsoil is where the nutrients and the water are. Once it's gone, the garden is in trouble.
Protecting the topsoil:
- Mulch. A 5 to 7cm layer covers the soil. The wind can't take what it can't reach.
- Ground cover. The plants that cover the soil also anchor it. Spekboom, vygies, even weeds in the worst spots are better than bare soil.
- Compost top-dressing. A 1cm layer of compost acts like a mulch and feeds the soil.
- Avoid tilling. Every time you turn the soil, you expose more of it to the wind. A no-dig or low-dig approach keeps the soil covered.
- Cover crops. If you have a vegetable bed that will be empty for a few months, plant a quick cover crop. Mustard, clover, lucerne. They protect the soil, then get dug in.
Plant Selection for the Wind
The plants that handle the North West wind are usually the ones that evolved in it. Indigenous and drought-tolerant options:
- Wild fig (Ficus). The thick leaves handle the wind. The deep roots anchor the tree.
- Karoo thorn (Vachellia karroo). The classic. The thorns are the price. The wind tolerance is the reward.
- Shepherd's tree (Boscia albitrunca). Slow-growing, evergreen, very wind-tolerant.
- Wild olive (Olea europaea subsp. africana). The small, leathery leaves handle the wind. The dense canopy provides shelter.
- Karee (Searsia lancea). The small tree or large shrub. Wind, drought, and frost tolerant.
- Spekboom (Portulacaria afra). The champion for the smaller garden. The small succulent leaves are perfect for wind.
- Cape honeysuckle (Tecoma capensis). The orange-flowering shrub. The flowers bring the sunbirds, the dense growth is wind-tolerant.
- Plumbago. The blue or white. The thin branches are surprisingly flexible.
A Simple Cleaning Routine
The North West garden cleaning is mostly about staying ahead of the wind. A quick weekly routine:
- Walk the garden. Look for the dust and the debris.
- Sweep the paving. The dust is slippery when wet.
- Empty the gutters. The leaves and the dust block them fast.
- Rake the lawn. The wind-blown leaves smother the grass.
- Top up the mulch. The wind takes the top layer first.
Once a month:
- Clean the windows. The dust on the outside is thicker than you think.
- Check the irrigation. The clogged nozzles and the cracked pipes.
- Trim the windbreaks. The hedges and the trees that protect the garden need the same attention as the rest.
- Aerate the lawn. The compacted soil from the wind-blown dust suffocates the grass.
Final Word
The North West wind is honest. It takes what isn't tied down. The gardener's job is to tie things down, in a way. Mulch on the beds, ground cover on the soil, indigenous plants in the wind, and a weekly routine to clean up what the wind brings. The dust is a constant. The debris is seasonal. Both are manageable. The garden that looks tidy in November is the garden where the owner did the work in August. The North West rewards preparation. The wind is a fair opponent if you know its rules.
