When to plant Lettuce in Boumerdes
Algeria
Lettuce is a fast, leafy salad crop grown for its crisp, tender leaves — and because people eat it raw, you must grow it clean.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 18 Sep 2026 – 3 Oct 2026 open now | 2 Mar 2027 – 1 May 2027 |
| Expected harvest | about 15.4 t/ha | about 23.9 t/ha |
| Harvest | From 2 Nov 2026 to 17 Dec 2026, depending on the planting date | |
| Ready to harvest | 45–75 days after planting | |
| Work it takes | 40–80 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 3 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Boumerdes 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 3 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Boumerdes
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For lettuce in Boumerdes, 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 Boumerdes
| When the rains are expected | September 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 676 mm in a typical farming district |
| Across its districts | From about 569 mm in the driest of 32 districts to about 1,042 mm in the wettest |
| This season's rain | Leaning dry — January, February, November 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 +1.1 °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 full main crop, warm, with a cool spell that slows winter growth |
| 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. |
| 73% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 243 growing days · about 770 mm · September to May |

Sloping ground holds back about 35% of yield here.
What lettuce needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Spacing | 38 cm between rows, 30 cm between plants |
| Feed it most with | nitrogen, potassium and calcium |
What it takes to grow lettuce in Boumerdes
| Nitrogen (N) | About 38 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 15 kg per hectare |
| Potash (K₂O) | About 77 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 | 40–80 days per hectare, by hand |
These are the nutrients a lettuce 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.
