This season's rainLeaning dry — January looks 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.

Frequently asked questions

What crops grow well in Riaba?

In Riaba the window for African nightshade runs 16 Feb 2026 to 14 Oct 2026.

Is there a farming app that works in Riaba?

Divisi does. It reads Riaba's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.

Is this exact for my own field?

No — these are readings taken across Riaba, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
