When to plant Teff in Blantyre
Southern, Malawi
Teff (Eragrostis tef) is a fine, tufted grass that carries the smallest grain of any cereal in the world — seed almost as fine as dust.
| Fit | Favourable |
|---|---|
| When to plant | 21 May 2027 – 30 Jun 2027 opens in 33 weeks |
| Expected harvest | about 3.5 t/ha |
| Harvest | From 20 Jul 2027 to 28 Oct 2027, depending on the planting date |
| Ready to harvest | 60–120 days after planting |
| Work it takes | 88–174 days per hectare, by hand |
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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Blantyre 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 30 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Blantyre
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For teff in Blantyre, the lie of the land is the tightest of the three at 88%. 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 2026/27 season in Blantyre
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to April 2027 |
| Rain in a typical year | About 952 mm |
| This season's rain | Leaning dry — January, February and December 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 +1.5 °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 one short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 64% of this area. |
| 64% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 171 growing days · about 930 mm · November to April |
|---|---|
| 34% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 216 growing days · about 1,040 mm · October to June |

Frost and pest pressure hold back about 15% of yield here.
What teff needs to grow here
| Soil it likes | sandy loam, loam, clay loam or clay |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.2 and 5.8 |
| Feed it most with | phosphorus, nitrogen, zinc, sulphur and boron |
What it takes to grow teff in Blantyre
| Planting material | About 3,000,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 105 kg per hectare |
| Phosphate (P₂O₅) | About 35 kg per hectare |
| Potash (K₂O) | About 88 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 | 88–174 days per hectare, by hand |
These are the nutrients a teff 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.
