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 grows in Colla with irrigation

These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.

Plan the season, not just check it

The crops and dates above are read at cells spread across Colla, 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.

Planting windows shift with the forecast. Leave your email and we'll send what changed, and a note when planting time nears — a couple of emails a month at most.

Frequently asked questions

What crops grow well in Colla?

Beetroot, Swiss chard, Chickpea, Garlic, Lettuce all rate well in Colla — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Beetroot in Colla?

In Colla the window for Beetroot runs 19 Sep 2026 to 11 Oct 2026.

Is there a farming app that works in Colla?

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