Coffee Farming Guide: Grow, Process & Sell for Export
Coffee is a long-term, high-value export crop where quality decides price. This guide covers arabica versus robusta, site and shade, planting, pruning, disease control, picking, wet and dry processing, grading, and how to sell green coffee directly to roasters and exporters for the premium quality earns.
Quick answer
To farm coffee profitably: match the species to your altitude (arabica in cool highlands for specialty premiums, robusta in warm lowlands for hardy reliable yield), grow under 30–50% shade, prune annually, control leaf rust and berry disease early, selectively hand-pick only ripe cherries, process carefully (washed for the highest cup scores), grade the green coffee, and sell direct to roasters and exporters. Quality and direct selling are where the margin lives.
Arabica or robusta?
Your altitude decides this more than your preference. Arabica needs cool highland conditions to develop the acidity and aroma that earn specialty prices, but it is fragile — vulnerable to leaf rust, berry disease and temperature swings. Robusta is the workhorse: hardy, disease-resistant and productive in hot lowlands, with a stronger cup that sells steadily into blends and instant coffee. Many farms grow whichever their land suits rather than fighting the climate.
| Factor | Arabica | Robusta |
|---|---|---|
| Altitude | 1,200–2,200 m | 0–800 m |
| Temperature | 15–24 °C, cool nights | 24–30 °C, warm and humid |
| Flavour | Aromatic, acidic, complex — specialty market | Strong, bitter, high caffeine — blends and instant |
| Disease resilience | Susceptible to leaf rust & coffee berry disease | More resistant and vigorous |
| Price | Higher; large specialty premium possible | Lower but steadier; reliable volume crop |
| Best for | Highland farms chasing specialty premiums | Lowland farms wanting hardy, reliable yield |
From planting to picking
Site & shade
Coffee thrives under 30–50% shade from leguminous trees, which moderate temperature, cut leaf rust pressure and improve cup quality. Choose deep, well-drained, slightly acidic soils (pH 5.2–6.0). Avoid waterlogged or frost-prone sites.
Planting
Raise or buy disease-free seedlings; transplant at the start of the rains at 2–2.5 m spacing (≈1,600–2,500 trees/ha). Mulch heavily to conserve moisture and suppress weeds. First commercial harvest comes in year 3–4.
Pruning
Annual pruning removes old, unproductive and diseased wood, opens the canopy to light and airflow, and concentrates the tree's energy into bearing branches. Stumping rejuvenates old trees on a multi-year cycle.
Nutrition
Coffee needs steady nitrogen, potassium and phosphorus plus micronutrients (boron, zinc). Apply in splits across the rains. A soil and leaf test prevents wasting fertiliser and corrects hidden deficiencies that cap yield.
Picking
For quality, selectively hand-pick only fully ripe red cherries in multiple passes. Strip-picking everything at once mixes unripe and overripe cherries and destroys the cup score — and the price.
Pest & disease control
Coffee leaf rust (Hemileia vastatrix)
Signs: Orange-yellow powdery spots on the underside of leaves; severe defoliation
Control: Plant rust-resistant varieties, prune for airflow, manage shade, apply copper fungicide preventively. AI rust-risk alerts on GeraFarm flag high-humidity infection windows.
Coffee berry disease (Colletotrichum)
Signs: Dark sunken lesions on green berries that rot and drop
Control: Resistant varieties, timely fungicide on green berries, sanitation of fallen cherries. Worst in cool wet highland conditions.
Coffee berry borer
Signs: Tiny holes in cherries; larvae tunnel the bean, cutting weight and grade
Control: Strip residual cherries after harvest, deploy alcohol/methanol traps, harvest promptly, biological controls where available.
Antestia bug
Signs: Damaged cherries and "potato taste" defect in the cup
Control: Open the canopy by pruning, scout regularly, treat hotspots; dense unpruned bushes harbour the pest.
Processing decides your price
After picking, processing is where good cherries become great coffee — or where a good harvest is ruined. Dry (natural) processing sun-dries whole cherries on raised beds; it is cheap, water-free and yields a heavy, fruity cup, but uneven drying risks mould and defects. Wet (washed)processing pulps the cherry, ferments off the sticky mucilage and washes the beans before drying; it costs more in equipment and water but produces the clean, bright, high-scoring coffee that earns specialty premiums.
Whichever method you use, dry beans slowly and evenly to about 10–12% moisture, rest them, then hull and grade by size, density and defect count. Consistent grading is what lets a buyer pay a confident premium.
Frequently asked questions
What is the difference between arabica and robusta coffee?
Arabica grows at high altitude (1,200–2,200 m) in cooler conditions, has a complex, aromatic, acidic flavour and commands specialty premiums, but is susceptible to leaf rust and berry disease. Robusta grows in warm lowlands (0–800 m), is hardier and more disease-resistant, has a stronger, more bitter, higher-caffeine cup, and sells at a lower but steadier price for blends and instant coffee.
How long until a coffee farm produces?
Coffee trees begin commercial production about 3–4 years after planting and reach full yield by year 5–7. A well-managed tree stays productive for 20–30 years, and old trees can be rejuvenated by stumping. Coffee is a long-term investment, so variety choice and site selection at planting matter enormously.
What is the difference between wet and dry processed coffee?
Dry (natural) processing dries the whole cherry in the sun — simple, low-cost, and gives a heavier, fruitier cup. Wet (washed) processing pulps the cherry, ferments off the mucilage and washes the beans before drying — more equipment and water, but a cleaner, brighter, higher-scoring cup that earns specialty premiums. Most quality-focused arabica is wet-processed.
How do I control coffee leaf rust?
Plant rust-resistant varieties, manage shade and prune for airflow to keep the canopy dry, remove infected leaves, and apply copper-based fungicide preventively ahead of humid weather rather than after pustules appear. GeraFarm AI advisory flags high-risk infection windows from local humidity data so you protect the crop in time.
How do coffee farmers earn more for their coffee?
Quality and direct access. Selectively picking only ripe cherries, processing carefully and grading green coffee lifts the cup score and the price tier. Selling directly to roasters, exporters and specialty buyers — rather than through layers of middlemen — captures the premium that quality earns.
