Why does garlic turn yellow? Main reasons

Very often, when there are shoots of garlic, and it begins to gain strength, gardeners observe a strange picture: the leaves of the plant become yellow. If we consider the time of planting, then the one planted under the winter is more prone to change. So why does winter garlic turn yellow? There are several reasons for this, which are related to technology and proper care. Or rather, with their violations. To establish the true cause of why garlic turns yellow, you need to apply an exclusion method.

Main reasons

1. Untimely landing

The teeth of the plant were planted ahead of schedule, and they managed not only to take root, but also to begin to grow. As a result, young, but weak shoots freeze even in the case of mild frost. The best time to board is deep autumn. Garlic turns yellow if the planted beds do not cover mulch for winter. To do this, use humus or compost.

2. Lack of fertilizers

Thinking about why garlic turns yellow, analyze the amount and time of insertion. For the winter variety, nitrogen is needed, which is very quickly washed out of the soil. Its shortage is replenished early in the spring, using nitrogen-containing mixtures or humus and urea. In autumn, mineral fertilizing is best not to use, they will go deep together with the spring water. It is better to use natural organic. With a shortage of potassium and magnesium, their sulfuric acid species are used, based on five liters of water, 10 g and 100 grams, respectively.

3. Soil acidity

Too acidic soils can be another reason why garlic turns yellow. In this case, it is necessary to add lime in the ground during its preparation for planting in any of its compounds. At increased acidity, about 60 kg of powder is needed per weave, 40 kg is taken for medium-earth soils, and 30 kg for slightly acidic soils.

4. Lack of water

When the head begins to form, regular watering is needed. This time is in May and June. Inadequate watering is one more reason why garlic turns yellow.

5. Diseases and pests

One of the important reasons why garlic turns yellow. The diseases include white and bacterial decay, black mold and fusariosis. This can be avoided by pre-soaking the seed in a solution of potassium permanganate. And if unprocessed teeth were planted, they spill the beds with a weak solution of water and salt - one tablespoon per five liters. Of pests, the most dangerous is the stem nematode. These little worms can not be seen with a simple eye. But their activity is easily seen through a magnifying glass, if you dig a couple of heads. They will show their presence by cracks around drying roots, flaking of scales and unpleasant odor. It is enough to dig out the garlic and consider the pests. Infected bulbs are removed from the site and burned outside. Neighborhood of garlic with calendula, thyme, marigolds, mint and coriander will serve as a good prophylaxis against parasites.

Wishes

It is not recommended to plant plants after potatoes and onions, they have the same disease. When yellowing leaves, garlic is fed with complex mineral fertilizers.
