How to Plan a Banana Farm
Six decisions made before planting that are expensive or impossible to change afterwards.
Most banana ventures do not fail in the field. They fail because the layout was decided with a spade instead of a plan, because irrigation was sized for a smaller field than the one planted, or because the harvest arrives before a buyer exists. This page is the pre-planting workflow.
Step 1 — Fix the field layout#
Layout decisions are permanent. Walk the land with these questions:
Where does water go? Mark every point where water enters and leaves, the flood line, and any hollow that ponds. Every other decision follows drainage.
Which way do rows run?
| Condition | Row direction | Reason |
|---|---|---|
| Flat, sloping < 3% | North–south | Even light on both canopy faces |
| Sloping 3–15% | On the contour | Erosion control outranks light |
| Hot, high-UV, low latitude | East–west | Afternoon sun on the narrow row face; less bunch scorching |
| Strong prevailing wind | Into the wind | Uniform aerodynamics, easier sheltered harvest lanes |
Where do access lanes go? You need to move harvested bunches (the heaviest, most time-critical item on the farm), fertiliser, mulch and sprayers. Plan a lane every 6–10 rows at a minimum, wide enough for the actual vehicle you will use — typically 3.0–4.0 m clear. Harvest lanes that also carry spray equipment should be on the windward side.
Where do drainage and irrigation mains run? Mainlines belong along lanes or contours so they are never driven over. Submains run at row ends. Drip or micro-sprinkler laterals run down the rows.
Where is the windbreak? Identify the prevailing wind direction and reserve a belt on that boundary. A double row of fast-growing trees (or a retained existing belt) sized to give a sheltered zone of 10–15× tree height.
Where is the staging area? Every farm needs a shaded, near-clean point where bunches are cut, de-handed or at least collected. Choose it before planting so harvest routes converge on it naturally.
Step 2 — Fix the spacing#
Spacing determines plant population, light interception, airflow, spray volume and machine access. Use the density calculator to run the numbers for your block.
Standard recommendations#
| Situation | In-row × between-row | Plants/ha | Notes |
|---|---|---|---|
| Cavendish export, flat land | 2.0 × 3.0 m | 1,667 | The global default |
| High-density, fertile, irrigated | 1.8 × 2.5 m | 2,222 | Higher total yield, smaller bunches, more spray |
| Low-input or dryland | 2.5 × 3.0 m | 1,333 | Bigger bunches, less competition |
| Plantain (French/Horn) | 2.5 × 3.0 m | 1,333 | Larger canopy, heavy feeder |
| Saba / processing types | 2.5 × 3.0 m | 1,333 | Big robust plant |
| Wind-prone site | 2.0 × 3.5 m | 1,429 | Wider rows for better anchorage and airflow |
| Steep contour planting | 2.0 × 3.0 m + grass strips | varies | Inter-row grass on the contour |
| Very high density (> 2,500/ha) | < 1.8 × 2.5 | > 2,500 | Only with intensive irrigation, nutrition and pruning — light limits yield per plant |
Triangular (offset) planting increases effective population by about 10–15% over square planting at the same spacings and improves light interception. Use it where machinery access is by lane rather than between every row.
Practical constraints#
- Sprayer clearance: leave enough width for your sprayer or knapsack operator to pass without damaging leaves.
- Harvest lane width: 3.0 m clear for a small truck, 4.0 m for a tractor with trailer.
- Root room and light: bananas root shallow and wide; below about 1.6 m in-row, canopy closure comes very early and lower leaves senesce from shading rather than disease.
Step 3 — Size the irrigation before planting#
Sizing after planting means either underwatering the whole block or retro-fitting laterals through a standing crop.
- Estimate peak demand. Peak crop evapotranspiration for a full canopy in the tropics is typically 6–9 mm/day.
- Convert to flow:
flow (L/h) = area (m²) × peak mm/day ÷ emitter spacing factors. For a 1 ha block at 7 mm/day you need roughly 70 m³/day ≈ 29 m³/h average, plus 20–25% for distribution losses. - Check the source can supply that continuously during the dry season, not just the wet season.
- Design for the day you cannot be there — automatic filtration, pressure regulation and a simple timer cost little and prevent crop loss.

Step 4 — Estimate labour honestly#
Banana farming is labour-intensive at three points: establishment, the mid-season desuckering/mulching cycle, and harvest.
| Activity | Labour per hectare per year (person-days) | Timing |
|---|---|---|
| Land preparation & planting | 15–30 (one-off) | Month 0 |
| Desuckering | 12–20 | Every 4–6 weeks from month 3 |
| Mulching / weeding | 20–40 | Establishment, then as needed |
| Fertiliser application | 6–12 | 4–6 splits |
| Leaf removal & propping | 8–15 | Flowering onwards |
| Spraying (if required) | 15–60 | Site and disease dependent |
| Harvesting, de-handing, packing | 40–90 | Continuous from month 10 |
| Total | ~120–280 |
A hectare at the high end is a full-time job for two or three people plus seasonal help. If your labour estimate is "we'll manage", it will not scale — build the number into the budget.
Step 5 — Write the budget#
An establishment budget for a 1-hectare Cavendish block typically breaks down as follows. Replace every figure with local prices using the farm budget calculator.
| Cost category | Share of establishment cost | What drives it |
|---|---|---|
| Planting material | 15–30% | Tissue culture vs suckers; clone chosen |
| Land preparation | 10–20% | Minimum tillage vs full ploughing; slope |
| Irrigation infrastructure | 15–35% | Drip vs micro-sprinkler; distance to water; pumping |
| Fertiliser and lime (year 1) | 10–20% | Soil test results; organic matter targets |
| Plant protection | 5–15% | Black Sigatoka pressure; residue programme |
| Mulch and weed control | 5–10% | Whether mulch is bought or farm-produced |
| Labour (establishment year) | 15–25% | Local wage rates |
| Windbreak, fencing, drainage | 5–15% | Site quality |
Operating costs from year 2 are dominated by labour, fertiliser and protection. Keep a contingency of 10–15%; almost every first plantation overruns.
The three numbers to know before you plant#
- Cost per hectare to first harvest — total establishment outlay.
- Yield at first harvest and at first ratoon — ratoons are usually 10–30% heavier than the plant crop if managed well.
- Farm-gate price per tonne net of packing and freight — not the headline market price.
Break-even is cost per hectare ÷ (net price × yield). If that is longer than your cash reserves support, scale down or delay, because the most common failure mode is running out of money in month 9 with a crop already in the ground.
Step 6 — De-risk deliberately#
| Risk | Likelihood | Mitigation |
|---|---|---|
| Drought during flowering | Medium–High | Irrigation sized for full dry-season demand; mulch 15–20 cm |
| Wind / lodging | Medium | Windbreak, propping plan, resistant spacing |
| Black Sigatoka | High in humid tropics | Protect leaf area: resistant clone, sanitation, spray programme |
| Panama disease (TR4) | Regional | Hygiene protocol: clean material, foot dips, no movement of soil or suckers from infected blocks |
| Bunchy top virus | Regional | Certified material only; rogue infected plants immediately; control aphids |
| Labour shortage at harvest | Medium | Diversified workforce, training, simple incentive scheme |
| Price collapse at harvest | Medium | Staggered planting, pre-harvest offtake agreement, two markets |
| Machinery or road failure | Low–Medium | Harvest routes that work on foot; contingency transport |
