Rubber farming guide for India
Rubber trees rely on steady rainfall; long dry spells reduce latex flow.

Typical values for India. Your soil test and your local KVK's advice come first.
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.
Before flowering
Many orchard crops are deliberately kept dry before flowering to induce bloom. A falling water signal in this window is expected, not stress.
Flowering
Bloom-time weather largely decides the season's crop: watch for heat, frost, rain and long humid spells.
Fruit development
Steady moisture now reduces fruit drop and improves size; a block that loses greenness faster than the rest deserves a visit.
After harvest
Recovery feeding and irrigation rebuild the tree for next season's bloom.
The main risks for rubber
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.
- Abnormal Leaf FallThe main risk for this crop in India.
- Abnormal leaf fallPhytophthora during monsoon.
- Pink diseaseHumid-weather stem infection caught early by microclimate monitoring.
Watering rubber well
Basin or drip irrigation tuned to the crop's stage, including the dry period some orchards use to induce flowering. Weekly field monitoring helps tell deliberate stress from real stress.
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.
A weekly message about your own rubber 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.

Rubber: common questions
What soil pH does rubber need?
Rubber grows best at a soil pH between 4.5 and 6.0. A soil test before the season is the reliable way to know your own field.
How much water does rubber need?
About 2000 mm over a season of roughly 365 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 rubber?
Abnormal Leaf Fall 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 rubber grown in India?
Rubber is grown as a Perennial (tapping from year 7) crop: June-July planting of budded stumps.
Which states grow the most rubber?
Leading states include Kerala, Tripura, Karnataka. VarshaKrishi's free Watch plan covers any field in these states: you need WhatsApp and your field's location, nothing installed in the field.
