We buy at Unjha, the main psyllium trading market in India, so this is the cycle we watch every week. Here is how the season runs, what actually moves the market, and how we suggest importers time their purchases.
The Season at a Glance
| Months | What happens in the field | What it means for buyers |
|---|---|---|
| October – November | Sowing across north Gujarat and western Rajasthan. Early November is generally considered the best sowing window. | Acreage is being decided. Watch sowing reports; they set the tone for the season. |
| December – January | Crop growth. Isabgol needs cool, dry weather. | Crop condition reports start to matter. Old-crop stocks are still trading. |
| February – March | Crop matures about 110–130 days after sowing; harvest. | The highest-risk window. Rain or heavy dew at maturity can cut yields sharply. |
| March onward | New-crop seed arrives at Unjha and other markets for processing. | The size and quality of the new crop become clear. Usually the best time to plan annual volumes. |
| Mid-year to September | No crop in the ground. | Prices move on stocks, export demand and expectations for the next sowing. |
What Moves Psyllium Prices
1. Sowing area
Farmers in the psyllium belt choose between isabgol and other winter crops such as cumin and mustard, and last season's prices weigh heavily on that choice. A strong psyllium price tends to pull acreage in; a weak one pushes farmers to alternatives. The area sown in October and November is the first real signal for the following year's supply.
2. Weather at maturity
This is the factor that surprises new buyers. Isabgol is unusually sensitive to moisture when it is ripe. Agricultural guidance for the crop notes that heavy dew or even a light shower at maturity can reduce yield proportionately, and in bad cases cause near-total loss, because the seeds shatter from the spike. A few days of unseasonal weather in February or March can change the market more than anything that happened in the previous four months.
3. Carry-over stock
How much seed and husk is left from the previous crop when the new one arrives cushions or amplifies a weak harvest. A small crop on top of low carry-over is when prices move fastest.
4. Export demand
India supplies most of the world's psyllium, so demand from the United States, Europe and other large importing markets feeds straight back into Unjha prices. Large forward buying by a few big importers can tighten the market before the crop is even harvested.
How Importers Time Their Purchases
There is no single right answer, but the buyers who get caught out are usually the ones who buy all of their annual volume at one point in the cycle. Approaches that work:
- Split the year. Cover part of your requirement before the new crop and the rest once arrivals show the crop's size and quality. You give up the chance of buying everything at the bottom, and you avoid buying everything at the top.
- Avoid being uncovered in February and March. If your stock runs out during harvest and the weather turns, you will be buying in the most volatile weeks of the year.
- Ask which crop year a lot comes from. Old-crop and new-crop material can both meet specification, but you should know which one you are buying, and the crop year belongs on the COA or lot documents.
- Agree price validity in writing. In a moving market, a quotation without a validity date is not a price. Ask how long it holds and what triggers a revision.
- Plan sterilized grades earlier. If you need steam-sterilized husk, production runs in batches of at least about 500 kg, so allow extra lead time. Our sterilization guide explains why.
The 2026-27 Season
Sowing for the 2026-27 crop begins in October and November 2026, with harvest expected in February and March 2027. That timing also matters for organic buyers: the market expects organic Transaction Certificates for US and Canadian supply to resume with the 2027 crop, as we explain in our organic supply update.
We deliberately do not publish price forecasts. What we can do is tell you what we are seeing at Unjha as the season develops. If you are planning 2026-27 volumes, send us your annual requirement and delivery windows and we will suggest how to split contracts across the season.
Frequently Asked Questions
1. When is psyllium (isabgol) sown and harvested in India?
Psyllium is a winter crop sown in October and November, with early November generally considered the best window. It matures about 110 to 130 days after sowing and is harvested in February and March.
2. When does new-crop psyllium reach the market?
New-crop seed starts arriving at Unjha and other Gujarat and Rajasthan markets from March onward, after the February to March harvest.
3. What causes psyllium husk prices to rise?
The main drivers are a smaller sowing area, rain or heavy dew at crop maturity that causes seed shattering and yield loss, low carry-over stocks from the previous crop, and strong export demand.
4. When is the best time to buy psyllium husk?
There is no single best month. Many importers split their annual volume, covering part before the new crop and the rest once March arrivals show the crop size and quality, and avoid being uncovered during the February to March harvest window.
5. Where is psyllium grown in India?
Mainly in north Gujarat and western Rajasthan. Unjha in Gujarat is the principal trading and processing centre for psyllium seed and husk.
