1. How to spend the winter

2. Water every few days in autumn

Potted sunflowers should be moved indoors as soon as possible after the temperature drops, and the temperature must be controlled. In winter, the best temperature can be maintained at 15-20 degrees, and the temperature should not be lower than 10 degrees, otherwise frostbite is easy. It should be exposed to more sunlight at ordinary times, so that it can see light throughout the day. This will not only satisfy its need for light, but also increase the temperature. At this time, watering should be reduced, and if it is not dry, do not water. In addition, if you want to survive the winter more safely, you should apply winter fertilizer before winter to improve its cold resistance.

1. How to survive the winter

1. Temperature control indoors: It is not winter-resistant. Potted plants need to be moved indoors after the temperature drops in late autumn. Pay attention to temperature control in winter. It is best to maintain the temperature between 15 degrees and 20 degrees. Once the temperature is below 10 degrees, growth will be affected and frostbite will easily occur.

2. Ensure light: It likes light very much, in winter The temperature is low and the sun is indispensable. Usually it should be placed on a windowsill with good lighting and exposed to sunlight throughout the day. This can not only meet the need for light but also increase the temperature. Opening hours are from 10 a.m. to 4 p.m.

3. Reduce watering: Water evaporates more slowly at low temperatures in winter, and its growth rate is also slower, requiring less water, so it should be watered less. Don't water until the soil is dry, usually water once every half month. When watering, it should be done at noon, and the water should be exposed to the sun in advance, so that the water temperature is close to the soil temperature before watering to avoid irritating the root system.

4. Apply winter fertilizer: before winter It is necessary to apply winter fertilizer once, and compound fertilizer is enough. This can improve its cold resistance and is beneficial to winter.

2. Water several times in autumn

Autumn can be divided into early autumn and late autumn. The temperature in early autumn is relatively high, and water evaporates quickly. Watering needs to be frequent, usually once a day or two, to meet its water needs. In late autumn, the temperature will drop, the water will evaporate slowly, and the plant growth will also slow down, so the frequency should be reduced. Generally, once a week or so is enough. Pay attention to the temperature and move indoors as soon as possible.
