| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 9 Mar 2027 – 17 Apr 2027 opens in 23 weeks | 29 Aug 2026 – 11 Apr 2027 |
| Expected harvest | 8.2–9.7 t/ha | about 15.0 t/ha |
| Harvest | From 8 May 2027 to 16 Jul 2027, depending on the planting date | |
| Ready to harvest | 60–90 days after planting | |
| Work it takes | 80–157 days per hectare, by hand | |
| Rain meets its needs | 97% | |
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 4 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Naivasha leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 17 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026 season in Naivasha
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | March 2026 to June 2026 |
| Rain in a typical year | About 576 mm |
| This season's rain | Leaning wet — November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.0 °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 all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 57% of this area. |
| 57% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 196 growing days · about 680 mm · February to June |
|---|---|
| 22% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 355 growing days · about 890 mm · February to January |
| 9% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 313 growing days · about 740 mm · February to January |
| 8% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 198 growing days · about 610 mm · March to June |

What spider plant needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Spacing | 30 cm between rows, 12 cm between plants |

What it takes to grow spider plant in Naivasha
| Nitrogen (N) | About 48 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 10 kg per hectare |
| Potash (K₂O) | About 58 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 | 80–157 days per hectare, by hand |
These are the nutrients a spider plant 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.
