Plan the season, not just check it

The crops and dates above are read at cells spread across Quillen, 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 Quillen?

Beetroot, Common bean, Swiss chard, Lettuce, Kale all rate well in Quillen — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Beetroot in Quillen?

In Quillen the window for Beetroot runs 21 Sep 2026 to 3 Oct 2026.

Is there a farming app that works in Quillen?

Divisi does. It reads Quillen'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 Quillen, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
