Why does garlic turn yellow in the garden: what to do, how to feed?

Growing vegetables is not easy, so good advice from experienced gardeners will always come in handy. Among the frequent problems in the cultivation of vegetable crops, the yellowness of garlic is also distinguished. Why does garlic turn yellow? There seems to be no particular reason for the yellowing of the feather, but the vegetable garden turns from green to yellow in spring or mid-summer, in July. The stems are usually dried before harvesting the garlic heads. It is clear that yellowing ahead of time will stop the growth of the bulbs.

Yellowing of garlic caused by frost

Garlic, although it is not afraid of frost, withstanding a short-term drop in temperature to minus three degrees, but with a prolonged cold snap, it begins to turn yellow.

Sudden temperature changes between day and night are common in temperate regions, and what to do if the tips of the leaves of garlic turn yellow. Given the change in weather, you can cover the bed with the plant with plastic wrap at night.

Winter types of garlic sprout in spring and immediately turn yellow and leaves droop. This happens due to the wrong timing of planting crops in the winter. Early planting will cause shoots to appear in the fall and freeze them when frost occurs. It is important to pay attention to the gardener's calendar to determine the planting dates for a particular year. In the middle lane, a crop is planted in the second or third decade of October, in warm areas - two weeks later.

The garlic is turning yellow, don't know what to do? Spraying with Zircon growth stimulator will help speed up the formation of young leaves in spring.

Overabundance or lack of moisture

The conditions for growing garlic include the composition of the soil, its level of moisture. The vegetable does not like too wet soils. Therefore, they choose a site with deep groundwater.

If garlic leaves turn yellow during a wet summer, this indicates oxygen starvation of the roots of the plant. Oversaturation with soil moisture leads to the appearance of a dense crust on top of the beds. You can correct the situation by loosening the earth, loosening the stem with raking the earth from the bulb. To avoid wetting of the stems and roots, it is better to grow the crop on high ridges.

During the dry season, the plant may lack moisture. Therefore, water the beds every week. In addition to water, when the garlic turns yellow, how to water during a drought? Choose nutrient solutions with growth stimulants. If there is a threat of frost, then shed the vegetable more often. So the leaves will begin to renew faster, and the vegetable plant will continue to grow.

Diseases and pests of garlic, as the cause of yellowing of the pen

A feature of garden culture is the smell of garden pests.But when the soil is infected with fungi and larvae, it is difficult to save the plant from diseases. And the first symptoms of unhe althy culture in the yellowing of the leaves, the stem, the appearance of brown spots on them. A diseased plant is unable to develop further, begins to dry out and dies.

To establish the reason why the garlic turns yellow in the garden, and what to do in this case, you can by examining the bulb, the stem of the plant. Even a visual inspection reveals the source of the problem:

The rot that appeared on the head of the vegetable is a symptom of fungal diseases: rot, rust. Infection with a fungal infection occurs through the soil or seed material. The disease, progressing, leads to rotting of the bulb and yellowing of the leaves. When the first signs appear, vegetable plantings are treated with Quadris. The procedure is carried out three times in two weeks.
Onion fly mold is also found on the bulbs. Pest larvae penetrate the stem, eating it. And the damaged areas are populated by pathogenic microorganisms that finish off the plants.
If yellow stripes appear on the tips of the leaves, and the stem is covered with brown strokes, then the vegetable is sick with Fusarium. You can cope with the first signs of infection by treating Fitosporin-M.
During the wet summer, the leaves of the plant turn yellow, and on the underside are covered with a white bloom. This powdery mildew fungus struck a vegetable. Fight microorganisms by spraying with preparations containing copper.
The stem onion nematode is dangerous for vegetable crops. Feeding on the juice of the plant, the larvae of the parasite lead to yellowing of the garlic, stopping its development. The leaves of the vegetable dry out, curl, and the head rots. The eggs of the pest settle in the bottom of the bulb, and the worms migrate, affecting neighboring plants.
If an onion fly has started up in the garden, it will be detected visually. Small light gray flies fly around garlic feathers. The larvae of the fly harm, which, having made their way into the bulb, eat it. You can determine the defeat of a vegetable by mold on the roots.Creolin or naphthalene is used to repel flies.

As soon as the yellowing of the leaves begins for no reason, it is necessary to carefully examine all parts of the plant to identify a disease or pest.

How to prevent disease?

From measures to prevent diseases of vegetable crops, experienced gardeners offer:

Don't plant garlic in the same place.
Before planting a vegetable plant, the bed is shed with a solution of potassium permanganate. Planting material is also soaked in it for twelve hours. Then washed and dried.
Greenhouse soil requires special attention. It must be replaced and disinfected annually.
You need to know how to feed the culture. If garlic turns yellow, then greenhouse pests can lead to a lag in its growth and vegetation. It is necessary to constantly monitor the condition of the soil in the room, disinfect it, and change it regularly.

Next to garlic, mint, calendula are planted, whose roots secrete special substances. They are poisonous to fungi and flying insects. And the onion fly is repelled by planting carrots. Get rid of the parasite by spilling the soil with saline.

Lack of nitrogen and other trace elements

For a full-fledged vegetation, garlic needs nitrogen, to a lesser extent potassium and phosphorus. When there are not enough elements in the soil, the leaves begin to turn yellow.

A single application of nitrogen will restore the vegetable plant. Repeat the procedure after two weeks.

If the leaves turn yellow, what is the best way to feed the garlic? From fertilizers containing nitrogen, urea is chosen. She is watered with emerging shoots of three liters per square meter. One tablespoon of urea per bucket of water is enough.

For dry top dressing during wet weather, carbamide is embedded in the grooves along the vegetable rows. Two grams of the substance is enough per square meter.

Yellowing of the feather can be avoided by timely fertilization.

Micronutrient deficiencies will also affect other crops growing next to garlic. Phosphorus reserves in the soil in July are replenished with wood ash. Garlic is enriched with other microelements using complex substrates Agricola, Kemiru. Fertilizers are applied either in dry form before digging the site, or with a solution, watering seedlings.

Green fertilizer - green manure is sown on the plot in four months. These include oats, white mustard. Then the greens are cut, and the stems are buried in the ground. Rotting, they will fill the soil with useful elements.

Spring garlic dressing recipe

If garlic leaves turn yellow, then the beds are treated with nutrient solutions in the spring. Here is the recipe for one of them:

Twenty liters of water are poured into the barrel, preferably rainwater.
Dilute in a liquid twelve grams of ammonium nitrate and potassium, twenty - superphosphate.
Seedlings are watered with liquid top dressing. The amount of fertilizer is enough for two square meters.
The procedure is repeated a month later, in June.

Applying fertilizer on time will allow the vegetable not only to take root, but also to fully develop.
