Is Marigold Cold Tolerant?

This introduction to the cold tolerance of marigolds will definitely be helpful to you. Let's take a look together!

Is Marigold Cold Tolerant?

Marigolds are not particularly cold-tolerant. The temperature should not drop below 5°C in winter. Once the temperature falls below 10°C, the growth rate of marigolds will slow down, and the growth cycle will be extended. Marigolds can freeze to death in winter, especially when the temperature is too low and remains below zero for an extended period. If the outdoor temperature in winter is low, measures should be taken to keep warm, either by moving them to a warm room or to a greenhouse.

Marigolds are native to Mexico and are distributed throughout China. Marigolds enjoy sunlight, and sufficient light can help them grow better. Marigolds thrive in warm environments, but the temperature should not be too high, as high or low temperatures can both have adverse effects on their growth.

Do Marigolds Get Cold in Winter?

Marigolds are sensitive to cold, with a suitable growth temperature between 15-20°C. Proper temperature control is essential for marigold blooming in winter, and they should be placed near a window with adequate sunlight to promote the formation of flower buds.

Cold Tolerance of Marigolds

Marigolds are not particularly cold-tolerant. The temperature in winter should not drop below 5°C. Once the temperature falls below 10°C, the growth rate of marigolds will slow down, and the growth cycle will be extended. Marigolds can freeze to death in winter, especially when the temperature remains below zero for an extended period.

Winter Care for Marigolds

1. Maintain Temperature

Marigolds do not have strong cold tolerance and can withstand temperatures around 5°C. As long as the temperature does not drop below 5°C, marigolds will not suffer from frostbite. They can grow normally at temperatures above 10°C. In southern regions with milder winter temperatures, they can continue to be grown outdoors in a sheltered, sunny location.

If the outdoor temperature in winter is low, measures should be taken to keep warm, either by moving them to a warm room or to a greenhouse. If the indoor temperature still does not meet the requirements, a simple保温 greenhouse can be made with plastic film.

2. Control Watering

Marigolds require some water to grow, but as the temperature drops in winter, the evaporation rate slows down, and the roots absorb less water. It's important to control watering and avoid overwatering. Generally, water every 7-10 days, following the principle of watering when the soil is dry and wet.

3. Maintain Humidity

If the indoor environment is very dry, you can spray water around the plant to maintain humidity and promote the growth of branches and leaves.

4. Sufficient Sunlight

Marigolds love sunlight and thrive in well-lit environments. Since sunlight is poor in winter, it is beneficial to expose them to more sunlight to promote good growth.

5. Pause Fertilization

Fertilize before winter. As the growth rate is relatively slow in winter and the demand for fertilizer is low, fertilization can be paused.
