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 10 Mar 2026. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Garr-Bain 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 18 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in Garr-Bain

Rain and temperature 96%
The soil 76%
The lie of the land 60%

For amaranth in Garr-Bain, the lie of the land is the tightest of the three at 60%. 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.

This season's rainLeaning dry — September and October 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 heatHotter than usual — about +0.9 °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.
