Cotton Growing Season Updated | 2026 |

The bolls open, and the fiber dries for harvest. 2. Critical Environmental Requirements

This is the critical phase. Inside the green boll, the cotton fibers (lint) and seeds develop. The plant requires ample sunlight and water during this phase. The boll grows to roughly the size of a golf ball.

But this whiteness is deceptive. Rain, dew, or even heavy fog can stain the lint or invite mold, dropping the grade—and price—in an afternoon. Farmers watch weather fronts like commanders. For a brief window, the crop is perfect. cotton growing season

Cotton flowers have a very short, dramatic life. On the first day, they open as a creamy white or pale yellow color. This is when pollination occurs, usually via self-pollination. By the second day, the flower turns a vibrant pink or red. Shortly after, the flower withers and falls off, leaving behind a small, green, berry-like structure called a "boll." Boll Development and Fiber Maturation

Cotton needs warmth to thrive. Farmers typically plant when soil temperatures reach at least 60°F (15°C) at a depth of 4 inches. This usually occurs between March and May, depending on the hemisphere. If planted too early, frost can kill the seedlings; too late, and the bolls won't have enough time to mature before winter.

The most water-sensitive stage; peak water demand occurs here.

If the soil is too cold, the seeds will rot or succumb to seedling diseases. Growers often wait for a "warming trend" to ensure the plant gets a strong start. During this phase, the primary goal is achieving a uniform "stand," where every seed emerges at roughly the same time. Vegetative Growth and Squaring Inside the green boll, the cotton fibers (lint)

Here’s the timeline: 1️⃣ Plant when soil is 60°F+. 2️⃣ Summer: Plants flower (white → pink → red) and bolls form. 3️⃣ Fall: Bolls crack open. Harvest time!

The journey from a tiny seed to a lint-filled boll involves several distinct biological milestones. Understanding this timeline is essential for anyone looking to understand the rhythm of a cotton farm. The Planting Window and Soil Requirements
