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.
What Divisi would not plant in Harper
Every crop in the catalogue is scored against this district, not only the ones that work — so the list above is a decision rather than a shortlist. These are the rest, with what ruled each one out.

Plan the season, not just check it
The crops and dates above are read at cells spread across Harper, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions
What crops grow well in Harper?
African eggplant, African nightshade, Amaranth, Bambara groundnut, Banana all rate well in Harper — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant African eggplant in Harper?
In Harper the window for African eggplant runs 10 Feb 2026 to 17 Nov 2026.
Is there a farming app that works in Harper?
Divisi does. It reads Harper'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 Harper, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
