Iran's date-growing calendar, and why it matters for buyers
Date palms in Iran's main growing belts — Bam, Jiroft, Saveh, and Khuzestan — go through a fixed yearly cycle: pollination in April, fruit set through June, and harvest running from late August into October depending on the variety and region. Piarom and Mazafati ripen earlier than Zahedi in most years. If you're placing a bulk order, that harvest window is what actually sets when fresh stock becomes available — not the date on a supplier's price list.
Why "planting" isn't the bottleneck
A date palm takes 4 to 8 years to bear fruit after planting and can keep producing for decades, so growers aren't replanting orchards on a seasonal basis. What varies year to year is weather during pollination and fruit set — a late frost or an unusually wet spring in Kerman province can cut yield noticeably, which shows up downstream as tighter supply and firmer pricing the following season, not as a planting delay.
What this means for import timing
Orders placed right after harvest (October through December) typically get the freshest stock and the most stable pricing, since supply is at its yearly peak. Ordering in the pre-harvest months (June to August) means working from the previous year's stored crop, which is still good if properly cold-stored but worth confirming the storage date on, not just the harvest year printed on the box.
Matching variety to season
If a specific variety matters more than "any dates now," it pays to ask a supplier directly which harvest month applies — Piarom sold in September is fresher than Piarom sold in May from the same crop year.
