When to Plant Maize in Kenya: Month-by-Month Planting Calendar (2026)

Introduction

Timing is everything when it comes to maize. Plant too early and seeds can sit in dry soil waiting for rain; plant too late and you risk your crop maturing right as the rains taper off. With the short rains season approaching, this guide breaks down exactly when to plant maize across Kenya's main growing regions, so you can plan your land preparation and seed purchases with confidence.

Why Timing Matters More During the Short Rains

Kenya's short rains (typically October to December) are shorter and less predictable than the long rains. That narrower window means a late planting decision can cost you the season. Choosing the right maize variety for your region's rainfall pattern, and getting seed in the ground at the right moment, gives your crop the best chance of reaching maturity before the rains end.

Regional Planting Calendar

Western Kenya: (North Rift - Uasingishu, Transioa) Short rains typically begin earlier here, often by early-to-mid September. Farmers in this region should aim to have land prepared by late August and plant as soon as the first reliable rains arrive.
Rift Valley (South Rift - Narok, Bomet, Kericho): Rains generally arrive in October. Land preparation should begin in September, with planting following the onset of consistent rainfall rather than the first isolated shower.
Eastern Kenya: Often the latest start, with rains arriving in October and sometimes into early November. Farmers here benefit most from fast-maturing varieties that can complete their cycle in a shorter window.
Coastal Kenya: Short rains (vuli) usually begin in October and can be more erratic, making drought-tolerant, fast-maturing varieties especially valuable.

Choosing the Right Variety for a Shorter Season

Because the short rains leave less margin for error, fast-maturing maize varieties are generally the safer choice over long-season hybrids. [Insert specific Royal Seed maize variety names and their days-to-maturity here, e.g., "Variety X matures in approximately 90 days, making it well-suited to Eastern and Coastal short-rains conditions."

Land Preparation Checklist

Clear and plough land at least 2–3 weeks before the expected onset of rains.
Conduct a basic soil check (see our related guide on soil testing) to confirm whether fertilizer or lime is needed.
Source certified seed early — short rains demand often causes stock shortages closer to the planting window.
Plant on the first reliable rains, not the first isolated shower, to avoid germination failure.

Conclusion

The short rains reward farmers who plan ahead. Knowing your region's typical onset, matching your variety to your season length, and preparing your land in advance are the three biggest levers you control.
