What should you pay attention to when overwintering spinach? A detailed explanation of the latest management points

Vegetables in winter are no longer as rare as they used to be, and many places grow vegetables in winter, with spinach being one of the choices for many people. When growing in winter, temperature is a big issue, so what should you pay attention to when overwintering spinach at this time? Let's take a look below at the key points to focus on when overwintering spinach!

1. Increase fertilizer to promote growth

Before overwintering, the size of the spinach is very important. If it is too small, it has no resistance to low temperatures at all; if it is too large, it increases the area exposed to the outside, making it more likely to freeze. Before overwintering, spinach should be given more fertilizer to promote growth, so that the leaves quickly grow to about 5-6 leaves, which is a more suitable stage for spinach to overwinter. At this time, the spinach itself has strong resistance, and the area affected by the outside is not very large. However, when fertilizing, pay attention to the amount and the combination, so that the spinach does not grow excessively and then freeze to death on a large scale!

2. Grass mulch protection

Grass mulch protection is divided into two types: one refers to covering with grass material, and the other refers to plastic film, and the choice between the two depends on the actual conditions in each place. If the local temperature is extremely low and there is more moisture, making it easy to freeze, then it is best to choose plastic film, as this gives a better heat-preservation effect. If there is more snowfall locally and there are more continuous snowy days, then it is best to use grass material as mulch. You can also decide between these two according to your own conditions. In general, you should start preparing to use them when low temperatures occur continuously, and not too late.

3. Control soil moisture

When the surface temperature reaches below zero, it will freeze, but this is not the case inside the soil. Many people think that making the soil a little more moist before overwintering will cause the spinach to freeze, but this is wrong. As long as the soil is not so moist that it becomes sticky and slippery, it basically will not freeze. A little moisture in the soil is also good for keeping warmth, because groundwater basically does not freeze, and it can keep the temperature inside the soil from dropping below zero, allowing the spinach to overwinter better. Therefore, before overwintering, you must control the soil moisture well.

4. Prevent frost

Frost during the overwintering period is the disaster with the greatest impact on spinach. Some of it is caused by snow and water falling at the same time, while some occurs when snow and water half melt during the day and then freeze again at night. When spinach faces this kind of disaster directly, the losses are basically severe. In the face of such a situation, you can consider using plastic sheeting on top of the spinach plot to block it, which can effectively reduce the losses from this disaster. Place the plastic sheeting at an angle and prepare several fixing points so that the wind does not blow it apart.

The above are some of the issues to pay attention to when overwintering spinach. In winter, many people cannot deal with these problems in time, so it is best to prepare in advance, and then there is no need to worry once winter arrives.
