Calendar and regions

When and where marigold is grown

Marigold is grown as a Year-round (three seasons) crop in India: Transplanted 30-35 days after sowing.

Leading states: West Bengal, Karnataka, Tamil Nadu. Soil moisture is best kept around 50 to 70% of capacity for most of the season.

Season, stage by stage

What to watch on your field

What a weekly satellite and weather view of your own field shows at each stage, and when to walk the field.

  1. Transplanting

    Steady root-zone moisture for quick establishment.

  2. Vegetative growth and pinching

    Even growth across the beds sets up even flowering.

  3. Bud formation

    Temperature swings at this stage affect flower size and timing.

  4. Bloom and picking

    Long humid spells raise grey mould risk; plan picking around the forecast.

The main risks for marigold

Most of these follow the weather. A risky week is a reason to inspect the crop, not to spray by default.

For any spray or dose, ask your KVK or an agronomist. VarshaKrishi's free Watch plan never names a product.

  • Red spider miteHot dry spells.
Irrigation

Watering marigold well

Drip or light irrigation with care to keep the canopy dry, balancing bloom size against disease risk.

Crop water use follows the FAO-56 method: the weather sets a reference demand, and the crop's stage sets how much of it the crop uses. That is why the same field needs different amounts in different weeks.

How VarshaKrishi helps

A weekly message about your own marigold field.

Watch is free for any field in India: what changed on your field this week, the weather for your village, and a clear note when the satellite cannot see. Decide opens crop by crop after an agronomist reviews each crop model.

Questions

Marigold: common questions

What soil pH does marigold need?

Marigold grows best at a soil pH between 6.0 and 7.5. A soil test before the season is the reliable way to know your own field.

How much water does marigold need?

About 500 mm over a season of roughly 90 days, from rain and irrigation together. The real need changes with the weather, the soil and the crop's stage, which is why it helps to track your own field week by week.

What is the main disease or pest risk for marigold?

Botrytis Blight is the main risk. Most risks follow the weather, so a risky week is a reason to inspect the crop. Ask your KVK or an agronomist before any spray.

When is marigold grown in India?

Marigold is grown as a Year-round (three seasons) crop: Transplanted 30-35 days after sowing.

Which states grow the most marigold?

Leading states include West Bengal, Karnataka, Tamil Nadu. VarshaKrishi's free Watch plan covers any field in these states: you need WhatsApp and your field's location, nothing installed in the field.
