In autumn, most areas grow vegetables such as spinach, leeks, garlic, and shallots, which emerge through a winter before they can be harvested the following year. Although these vegetables have a strong ability to withstand cold, can they safely overwinter? How are you doing in the coming year? Management from the time of emergence to the beginning of winter is very important. Therefore, whether it is spinach, leeks, garlic or shallots, you can't neglect management before winter. The main management methods are as follows.
1. Remove weeds in time
After spinach, leeks, garlic, and shallots emerge, until the winter, they should not be allowed to grow grass in the ground, and once weeds occur, they should be removed in time. Because the vitality of weeds is very strong, if there are weeds, if they are not removed before winter, they will germinate prematurely in the spring of the next year, and the root system is also deep, and it is a bit laborious to clean up, which not only affects the growth of seedlings, but also takes labor and effort. Again, when removing weeds, vegetables such as spinach and shallots, if the seedlings are too crowded, by the way, even the seedlings are carried out together to avoid poor growth of the seedlings when they return to green in the next year.
2. Watering reasonably
Under normal circumstances, some overwintering vegetables do not need to be managed too much before winter, but in order to grow better in the coming year, proper management is necessary. Regardless of spinach, garlic, shallots, or leeks, after the emergence of seedlings, the soil can neither be too dry nor too wet, just keep the soil moist. When garlic, spinach and shallots grow to more than 3 leaves, you can properly control the water and promote the roots, so that the root system goes deeper, the root system is developed and robust, not only the cold tolerance is enhanced, and the seedlings will grow strong and lush when they return to green in the next year.
3. Control the seedling growth and too high
Whether it is spinach, garlic or shallots, due to the influence of planting time and temperature, sometimes the seedlings will grow very tall and long. Therefore, before winter, it is necessary to control the seedlings to grow too fast, if the seedlings grow too fast, the plants are tall, and they are easy to be frostbitten when they encounter low temperature weather in winter, and then another, the seedlings grow tall, and they are easy to sprout too early when they return to green in the next year, which not only reduces the yield but also affects the quality. The only way to control the seedlings from growing too fast is to control the watering, not to water too much, as long as the soil is not particularly dry, do not water too much.
4. After the emergence of seedlings, there is no need to fertilize
When it comes to fertilization, no matter what kind of vegetable it is, it is necessary to flexibly decide on the basis of growth and soil fertility. For example, vegetables such as garlic, shallots, spinach, etc., if the base fertilizer is used sufficiently at the time of planting, then there is no need to carry out top dressing before winter. If you don't use base fertilizer when planting, or use too little base fertilizer, then you can apply fertilizer once when it grows to about 4 leaves, and the fertilizer can be organic fertilizer, compound fertilizer, etc. But for leeks, it is best to apply fertilizer once before winter, plant ash, organic fertilizer can be, sprinkle fertilizer directly around the roots, be careful not to bury the leaves.
5. How to water the wintering water
Many friends have heard of wintering water, what is wintering water? Overwintering water is the water that is watered before the soil freezes, the purpose is to prevent drought and frost damage in winter, balance the ground temperature, and enhance the frost resistance of crops. However, the wintering water cannot be watered casually, and needs to be decided according to the soil moisture and dry humidity. If the soil is dry before freezing, it is necessary to water it again, the best time to water the wintering water is to thaw the soil during the day, and watering when the soil begins to freeze at night, the time is good in the morning, but the watering should not be too much, and it should not be too late, and the soil is not dry or wet, and the water can all penetrate into the soil after watering. If the soil is not dry before winter and the surface is in a semi-dry and semi-wet state, there is no need to water. Specifically, it can be flexibly grasped according to the dryness and wetness of the soil.
The above are several key points of management of spinach, leeks, garlic and shallots before winter, and how to manage them flexibly according to the local climate, soil and seedling growth.
