How to spend the winter in potted sunflowers? How often should you water them in autumn?

1. How to spend the winter

1. Control the temperature indoors: It is not winter-resistant, so potted plants should be moved indoors when the temperature drops in late autumn. Pay attention to temperature control in winter, it is best to maintain the temperature between 15 and 20 degrees. Once the temperature drops below 10 degrees, it will affect growth and cause frostbite.

2. Ensure light: It likes light very much. The temperature is low in winter, so it cannot live without sunlight. It should be placed on a windowsill with good light and exposed to sunlight all day long. This can not only meet the need for light, but also increase the temperature. The exposure time is from 10 am to 4 pm.

3. Reduce watering: In winter, the low temperature causes water to evaporate more slowly, its growth rate is also slow, and the demand for water decreases, so you need to water it less. Don’t water until the soil is dry. Generally, water once every half a month. And the best time to water is at noon, dry the water in advance, and water when the water temperature is close to the soil temperature to avoid irritating the root system.

4. Apply winter fertilizer: Apply winter fertilizer once before winter. You can use compound fertilizer. This can improve its cold resistance and is beneficial for wintering.

2. How often should I water in autumn?

Autumn can be divided into early autumn and late autumn. The temperature in early autumn is relatively high and water evaporates quickly, so you need to water it frequently, usually once every one or two days, to meet its water needs. In late autumn, the temperature will drop, water will evaporate slowly, and the growth of plants will also slow down, so the frequency of weeding should be reduced. Generally once a week or so is enough. Also pay attention to the temperature and move it indoors as soon as possible.
