Temperature Essentials for Maize

Regional wintering strategies

Maize prefers relatively warm temperatures, so maintaining temperatures above 20°C during winter cultivation is beneficial for plant growth. The minimum temperature should be kept above freezing point to prevent the plant from freezing damage. When the outdoor temperature approaches -5°C (25°F) during winter, it is advisable to bring Maize indoors or provide protection by setting up a temporary greenhouse or using materials such as plastic film or fabric to wrap the plant.

Signs of Low and High Temperature in Maize

Symptoms of Low Temperature in Maize

Maize has moderate tolerance to low temperatures and thrives best when the temperature is between 20°C and 38°C. During winter, it should be kept above 0°C. When the temperature falls below -40°C, the leaves may darken in color. In severe cases, water-soaked necrosis, wilting, and drooping may occur, and the color of the leaves gradually turns brown.

Solutions for Low Temperature in Maize

Trim away the frost-damaged parts. Immediately move indoors to a warm environment or set up a makeshift greenhouse for cold protection. When placing the plant indoors, choose a location near a south-facing window to ensure ample sunlight. If there is insufficient light, you can use supplemental lighting.

Symptoms of High Temperature in Maize

During summer, Maize should be kept below 38°C. When the temperature exceeds 43°C, the plant's growth slows down, the color of its leaves becomes lighter, and it becomes more susceptible to sunburn.

Solutions for High Temperature in Maize

Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the afternoon sun. Water the plant in the morning and evening to keep the soil moist.
