When to plant Watermelon in M'Fatha
Medea, Algeria
Watermelon is a warm-season trailing vine, grown flat along the ground for its big, sweet, thirst-quenching fruit — a cousin of pumpkin, cucumber and melon.
| Fit | Favourable |
|---|---|
| When to plant | 21 May 2027 – 20 Jul 2027 opens in 33 weeks |
| Expected harvest | about 34.2 t/ha |
| Harvest | From 9 Aug 2027 to 7 Nov 2027, depending on the planting date |
| Ready to harvest | 80–110 days after planting |
| Work it takes | 46–96 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 M'Fatha is close to normal, so these dates match the pattern the area usually follows.
Planting after 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in M'Fatha
| Rain and temperature | 96% |
|---|---|
| The soil | 88% |
| The lie of the land | 45% |
For watermelon in M'Fatha, 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 2026/27 season in M'Fatha
| When the rains are expected | October 2026 to March 2027 |
|---|---|
| Rain in a typical year | About 372 mm |
| This season's rain | Rain close to usual — plan around about 372 mm falling roughly when it always does |
| 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, with a cool spell that slows winter growth |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 76% of this area. |
| 76% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 163 growing days · about 380 mm · October to March |
|---|---|
| 14% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 187 growing days · about 430 mm · October to April |
| 10% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 184 growing days · about 430 mm · October to April |

What watermelon needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |

What it takes to grow watermelon in M'Fatha
| Planting material | About 4,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 75 kg per hectare |
| Phosphate (P₂O₅) | About 21 kg per hectare |
| Potash (K₂O) | About 109 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 | 46–96 days per hectare, by hand |
These are the nutrients a watermelon 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.
