When to plant Robusta coffee in Liberia
Robusta (Coffea canephora) is a hardy evergreen coffee tree of the warm lowlands — bigger, tougher and higher-yielding than highland Arabica, and far better at shrugging off leaf rust.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 21 Jan 2027 – 1 May 2027 opens in 16 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 1.6–1.7 t/ha | about 2.8 t/ha |
| Bearing cycle | 270–330 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 122–255 days per hectare, by hand | |
| Rain meets its needs | 96% | |
Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Liberia leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 1 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Liberia
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 45% |
For robusta coffee in Liberia, the lie of the land is the tightest of the three at 45%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
The 2025 season in Liberia
| When the rains are expected | February 2025 to December 2025 |
|---|---|
| Rain in a typical year | About 2,150 mm in a typical farming district |
| Across its districts | From about 1,763 mm in the driest of 136 districts to about 4,684 mm in the wettest |
| This season's rain | Leaning dry — September and October look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +0.8 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can. |
| What that supports | enough rain for a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 96% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 347 growing days · about 2,470 mm · February to December |
|---|---|
| 4% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 2,780 mm · January to December |

What robusta coffee needs to grow here
| Soil it likes | sandy loam, loam or clay loam |

What it takes to grow robusta coffee in Liberia
| Planting material | About 1,350 plants per hectare |
|---|---|
| Nitrogen (N) | About 56 kg per hectare |
| Phosphate (P₂O₅) | About 11 kg per hectare |
| Potash (K₂O) | About 62 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 122–255 days per hectare, by hand |
These are the nutrients a robusta coffee crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
