What temperature is best for watering garlic during the winter?

When planting garlic , if you want to know whether it needs wintering water, you can determine it based on the actual rainfall and field moisture conditions. If the rainfall is heavy and the field moisture is sufficient, you can reduce watering appropriately; otherwise, you will need to add water in time according to the condition of the seedlings. So what temperature is most suitable for watering garlic during the winter? Let’s take a look with the editor below.

1. What temperature is most suitable for watering garlic during the winter?

The most suitable temperature for watering garlic over the winter is when the temperature is above 5 degrees. This is because it is not recommended to water when the temperature drops to 1-2 degrees to avoid freezing and frostbite the plants. Therefore, in order to ensure the safety of garlic over the winter and enhance its frost resistance, it is best to water the garlic during the winter when the temperature is higher, that is, when the temperature is above 5 degrees, so as to avoid frost damage to the garlic caused by low temperature.

2. How to water garlic during the winter?

1. Weather selection

When watering during the winter, you should choose sunny weather after a continuous night of frost and the freezing during the day. Under such weather conditions, the soil temperature is relatively stable, water is not easy to evaporate too quickly, and the stimulation to the garlic roots can be reduced.

2. Watering time

It is more suitable to water after 10 am and before 4 pm. If you water before 10 a.m., the soil temperature may not have risen yet, and the water will further lower the soil temperature, which is not conducive to the activity of the garlic roots; while if you water after 4 p.m., as the temperature drops, the soil moisture evaporates slowly, which can easily cause the soil to be too humid.

3. Watering method

① Ground watering: Suitable for garlic planted in a small area. When watering, you need to pay attention to the amount to avoid stagnant water and suffocation of the garlic roots.

② Furrow irrigation method: Suitable for large-scale planting of garlic. Dig furrows in the garlic planting area and then irrigate water from the furrows, which can effectively guide water to the area around the garlic roots. But you need to control the amount of water and avoid overwatering.

③ Drip irrigation: It is a precise, economical and efficient way of watering. It can supply water in a fixed amount according to the water demand of garlic, saving water and energy. Suitable for large-scale planting of garlic with high benefits.

4. Watering amount

Watering should be done lightly with small amounts of water to keep the soil moist. Avoid heavy flooding that causes water to accumulate on the ground and form an ice layer that may suffocate the hair roots. Generally speaking, 20-30 cubic meters of water per acre is appropriate.

5. Watering frequency

The growth rate of garlic slows down in winter, and the frequency of watering is generally once every 7-10 days to avoid excessive watering which will lead to the loss of nutrients in the soil.

The above is an introduction to the most appropriate temperature for watering garlic over the winter. The best temperature condition for watering garlic over the winter is when the temperature reaches about 0℃ to 3℃. At this time, the temperature in the 5cm soil layer is about 5℃, and the surface soil shows the phenomenon of "melting during the day and freezing at night".
