How to manage asparagus in winter?

Asparagus is a nutritious vegetable that contains many vitamins and minerals. Asparagus has a well-developed root system, consisting of fleshy storage roots and fibrous absorbing roots. It likes to grow in deep, well-drained, fertile sandy loam. So how do you manage asparagus in winter? Let’s take a look with the editor below.

1. Apply winter fertilizer heavily

After the autumn harvest, winter fertilizer should be applied again in batches to meet the needs of underground root growth. Apply winter fertilizer twice during the two solar terms of "Lidong" and "Winter Solstice", mainly organic fertilizer , such as soil and miscellaneous fertilizer, calcium magnesium phosphorus, ammonium bicarbonate, etc., and mix with peanut cake, bone meal, etc. before fermentation and application.

2. Prune branches and leaves

When the asparagus leaves gradually turn yellow in winter, the branches and leaves should be cut directly above the roots, leaving 5-6 cm above the ground. This can reduce nutrient consumption and concentrate supply on the root system. After pruning, clean up the cut parts to avoid piling up on the ground and affecting the growth of asparagus.

3. Garden cleaning and disinfection

During the period from "Great Cold" to "Start of Spring", depending on the degree of yellowing of the plants on the ground, the plants should be cut off one after another, and the stems, leaves, dead branches, weeds, etc. of the plants should be thoroughly cleaned up, moved out of the field and burned, and the weeds in the bamboo shoot garden and the surrounding area should be removed to eliminate overwintering parasites and pathogens.

4. Ditch cleaning and stain prevention

Asparagus has fleshy roots. When the soil contains too much water, it is susceptible to frost damage or root rot in winter. Therefore, it is necessary to clear ditches in time to lower the groundwater level and prevent waterlogging and root rot.

5. Water before freezing

After the beginning of winter, the last watering should be done before the soil freezes. This watering is commonly known as "freezing water". Based on the principle of "watering before freezing and not watering after freezing", it is very beneficial to prevent winter drought, keep the soil moist, and protect the bamboo shoots safely over the winter. It is also beneficial to the emergence and growth of young shoots in the spring of the second year and reduce the hollowness of asparagus.

6. Fertilization management

In winter, as the growth rate of asparagus slows down, it needs to be supplemented with nutrients in time. The frequency of fertilization can be appropriately increased, with urea, compound fertilizer , etc. applied once every week. At the same time, be careful not to over-fertilize, which can cause root burns and wilting in the asparagus.

The above is an introduction to how to manage asparagus in winter. The temperature is low in winter. If you encounter severe weather such as heavy snowfall, strong winds, etc., you need to take timely measures to protect the asparagus from damage. You can cover the base of the asparagus with a certain thickness of straw, rice straw, etc. to avoid frost damage and low temperature damage.
