When to plant Swiss chard in Pwani
United Republic of Tanzania
Known here as mchicha
Swiss chard — muriwo, mchicha, silverbeet, spinach beet — is the dependable 'spinach' of African markets and home gardens, though it is not true spinach.
| Fit | Favourable |
|---|---|
| When to plant | 21 May 2027 – 30 May 2027 opens in 33 weeks |
| Expected harvest | about 46.3 t/ha |
| Harvest | From 18 Sep 2027 to 26 Nov 2027, depending on the planting date |
| Ready to harvest | 120–180 days after planting |
| Work it takes | 73–145 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 Pwani is close to normal, so these dates match the pattern the area usually follows.
Planting after 30 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Pwani
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For swiss chard in Pwani, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026/27 season in Pwani
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to June 2027 |
| Rain in a typical year | About 967 mm in a typical farming district |
| Across its districts | From about 892 mm in the driest of 7 districts to about 1,534 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 967 mm falling roughly when it always does |
| 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 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. |
| 60% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 247 growing days · about 940 mm · October to June |
|---|---|
| 36% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 278 growing days · about 910 mm · September to June |
last updated 17 September 2026 · from all 7 areas within it

What it takes to grow swiss chard in Pwani
| Planting material | About 200,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 162 kg per hectare |
| Phosphate (P₂O₅) | About 58 kg per hectare |
| Potash (K₂O) | About 278 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. |

These are the nutrients a swiss chard 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.
