The most common plant for improving a planting site is mustard, however, besides it, there are other herbs that are successfully used as green manure.

Green manure for winter garlic

Green manure is widely used and is used to improve soil quality before planting crops. For garlic, which is planted before winter, beneficial herbs provide good nutrition, protect it from damage to the cloves by pests, while the garden crop germinates early in the spring and actively develops. On the hundredth day after germination, the gardener can already dig up bulbs that will be large, fragrant and shelf-stable.

Expert opinion

Filatov Ivan Yurievich, private farmer for more than 30 years

In the absence of fertilizer plants, garlic yield decreases. The use of companion plants increases the content of minerals, nitrogen, starch, sugars and proteins in the soil, which are necessary for the proper development of vegetable crops. The root system of auxiliary plants is deep and does not allow the soil to become excessively compacted, as a result of which its water and air permeability increases.

In areas with harsh winters, herbs additionally insulate the soil, helping garlic plantings survive frosts. In such a situation, they do not embed the satellite plant into the ground, but leave it to grow so that by frost it will lie on the bed, covering it. At the time of planting the crop, the height of the satellite shoots should be at least 20 cm.

Plants from six groups are used as fertilizers. Which type to choose depends on the quality of the soil and the possibility of purchasing planting material.

1. Cruciferous . The most commonly used of these companion herbs are mustard, rapeseed and oilseed radish. They are unpretentious and quickly improve the soil, and are also effective in combating a number of pests and diseases of garlic and root crops. Green manures of this group effectively suppress the growth of most major weeds.
2. Legumes . Representatives from this group include vetch, alfalfa, lupine, sweet clover and beans. Any soil is suitable for the listed herbs; they also enrich it with beneficial bacteria and nitrogen and provide it with sufficient looseness. Legumes clear the planted area of ​​nematodes and also prevent the growth of weeds on it.
3. Cereals. They can grow in a variety of soils, including loamy and sandy soils. These herbaceous plants help improve soil permeability and reduce the intensity of leaching and weathering of the nutrient top layer. They enrich the soil with potassium. It is best to plant cereals as green manure in areas with high acidity.

4. Buckwheat . They help enrich even poor soil with phosphorus, potassium and organic compounds. Increases the lightness of the soil and its fertility.
5. Amaranthaceae . They increase the nitrogen content in the soil, improve its fertility and prevent compaction.
6. Hydrophilic . Such herbs will be reliable protection against weeds and various bacterial diseases for crops, including garlic. When using these green manures, oxygen exchange in the soil improves, it becomes lighter, and its acidity decreases, approaching neutral.

For garlic before winter, it is best to choose cruciferous, hydrophilic or, in extreme cases, cereal green manures. The remaining species are more suitable for spring planting.

Advantages of green fertilizer

In addition to cost, site greening has the following advantages:

• The chemical composition of green fertilizer is similar to manure, but is considered the best green manure for garlic and onions because it contains phosphorus - one of the main factors for long-term storage of products and a growth stimulant. Phosphorus is added to manure in the form of superphosphate, since animal organic matter does not contain phosphorus.

• Green manure suppresses the growth of weeds - their powerful root system prevents “competitors” from breaking through to the light and receiving food at the surface. Along with manure, on the contrary, weed seeds are introduced into the soil, since they have a strong shell that is not digested in the stomach of animals under the influence of digestive juices.

• Almost all green manure crops contain active substances that repel beetles, caterpillars, and rodents. When using them, you can achieve a clean, undamaged crop that will be stored longer.

• When growing green manure, nitrates do not accumulate. It is advisable to use mineral fertilizers at the growth stage; many do this so that green manure does not deplete the soil and does not remove the last nutrients. But then the plants process the minerals into organic matter, and this is a safe, environmentally friendly fertilizer.

• In many species, the roots reach 1.5 meters in depth. This is good for the main crops - they do not compete for food and water; it is good for green manure - they obtain nutritional components that are washed into the lower horizons of the soil after rain.

• They reduce acidity, allowing the main crops to fully absorb all substances in a balanced manner.

When the above-ground part is cut off, the root system of green manure remains in the soil. When rotting, it leaves empty spaces that are filled with water and air, providing plants with moisture and oxygen.

The benefits of using green manure when growing onions

Using organic fertilizers to grow onions and garlic, we obtain environmentally friendly products that have good taste and nutritional characteristics. Organic matter does not deplete the soil.

Regular planting of green manure helps to increase the fertile layer and the content of humus in it - organic matter. Soil microorganisms and insects that loosen the soil feed on plant residues.

Mulching with organic matter helps retain moisture and propagate beneficial microflora. When sowing onions in green manure, they are less affected by various diseases, which increases the shelf life of the fruit in winter. Using green manure plants as intercrops, one type of vegetable crop can be planted several times.

Planting winter garlic in green manure

How to plant garlic in green manure? Planting crops in green manure in the fall should be done correctly in compliance with a number of rules. You can plant the crop both after digging up the area, when the enriching herbs are already mixed with the soil, and where they are still growing. It is best to use white mustard as a feeding plant, which will reliably protect garlic from pests and diseases.

Is it possible to plant garlic immediately after planting green manure in the soil? Usually you need to start this only 4-6 days from the moment the green mass was dug into the soil. If mustard is used, you should wait at least 2 weeks. When cereals are used as fertilizer, garlic can be planted within 2-3 days.

You can also plant garlic in growing green manure before winter with high efficiency. In this case, the auxiliary grasses will cover the ground with the onset of cold weather and reliably protect the plantings from frost, and also prevent them from freezing if the winter is snowless or little snow.

Among the growing herbs, garlic is planted in two ways.

1. First way . In this case, green manure should form a continuous carpet, which is especially suitable for mustard. The crop is planted in rows among useful plants. The roots of the grass will not interfere with its growth, but will only improve the soil around it. Green fertilizers do not compete with vegetables, since they begin to develop only in spring, when the grass has already died from winter frosts and becomes food and protection for plantings.
2. Second way . With it, auxiliary herbs should be arranged in rows, between which the vegetable will be planted.

The choice of planting method depends only on personal preference.

What green manure should I sow after garlic? After harvesting the garlic, it is imperative to plant useful plants in the garden to restore the soil. This technique will prevent subsequent plantings from losing quality. To maintain soil fertility, it is recommended to plant legumes after garlic, which will increase the amount of nitrogen. Green manure and garlic grow well together without being competitors for each other, so they can be planted side by side.

Gardening Tips and Tricks

Experienced gardeners often resort to some tricks when planting garlic in the fall before winter, which allow them to get a rich and tasty harvest the following year.

These techniques can be used by both beginners and those who are planting garlic before winter for the first time. So, these tricks include:

1. Determination of soil acidity using an acid meter. An acid meter is a specialized device that allows you to determine the Ph level with maximum accuracy.
2. Timely preparation of the bed. It may vary from region to region, but it is best to start it in August. This is done to ensure that the loosening period lasts as long as possible: this will remove all weeds from the bed.
3. The right choice of location. It is necessary to take into account not only the composition of the soil substrate, but also the geography of the site. Garlic should not be planted before winter in poorly lit lowlands where rainwater accumulates. Even if garlic can cope with a lack of light, excess water will be detrimental to it.

The best green manure for garlic

What kind of green manure should I plant in front of garlic? Agrotechnicians recommend using any of the following plants to improve the soil before planting garlic.

1. White mustard . The grass is unpretentious, perfectly loosens the soil and increases its nutritional value, saturating it with organic matter. In addition, mustard suppresses weeds and repels pests. The plant can be planted in autumn and spring.
2. Phacelia . A plant that is resistant to adverse weather conditions, loosens the soil and increases the organic content in it. You can plant grass on any soil. After this, there is no need to additionally feed the area.
3. Oats . This cereal can be sown on various soils. It requires watering to grow fully. It is best to plant the plant in early spring, and plant it in the ground in mid-summer. Then, by the time winter garlic is planted, the soil will become quite nutritious.
4. Clover . Grass increases the nitrogen content in the soil. Green manure should be grown on moist soils. It is good to plant it between the rows of garlic. To maintain soil fertility, it is enough to sow clover once every 3 years.
5. Sweet clover . It is planted to improve the quality of the soil structure and enrich it with nitrogen, as well as cleanse the area of ​​pathogenic bacteria. The plant can tolerate drought and frost.

conclusions

Green manure for garlic and onions is a complete and pure organic fertilizer.
Their use in a summer cottage reduces the cost of vegetables, as well as labor costs in the greenhouse and open ground. There is no need to use chemicals against pests and weeds, since alkaloid substances do an excellent job using natural methods. Did you like the article?
