Yellowing garlic

• temperature drops;
• improper watering;
• diseases and pests;
• lack of trace elements.

Temperature differences

Frost has a bad effect on garlic in the following cases:

• Too early planting. Recommended planting dates for each crop. If you plant garlic earlier, sprouts will appear on it before the onset of winter. When the cold comes, the leaves will freeze, and in the spring they will turn yellow.
• Frosts in winter or spring. If a young feather of garlic has come under freezing, the yellowing process begins. To minimize the effect of cold temperatures, the soil is mulched in autumn. Fallen leaves are suitable for this. The thicker their layer, the better the culture is protected from the negative effects of frost.The same advice can be given so that the onions do not freeze.

If you still managed to protect the plant from the cold, spray the stem with stimulants such as Epin, Zircon, Energen. They will contribute to the development of the bush.

Wrong watering

Due to the drought, the garlic feather turns yellow

Insufficient watering causes the stem to turn yellow. Garlic is watered regularly. Particular attention is paid to this in May and June, because it is then that a bush is formed.

In spring, when the snow melts, they check the condition of the soil. The soil near the garlic is loosened and see how moist it is. If the amount of moisture is insufficient, the plant begins to be watered regularly.

If the soil is excessively moist (if the bed is close to the reservoir), there is a need for drainage channels along the rows of bushes.

It’s not worth watering the garlic too much: it also contributes to the yellowing of the leaves. This usually happens if there is clay soil on the beds. In this case, the moisture may stagnate in the soil.

Water for irrigation is taken standing. It must preheat in the sun. If the weather is not very hot, there is rainfall, use about 10 liters of water per 1 square. m of soil.

During heavy rains, air access to the roots is impaired. To avoid this, the soil is loosened, and then slightly moved away from the bulbs.This frees up space and provides oxygen access to the upper bulb. Leaves are also tied. Due to this, nutrients enter the bulb better.

Diseases and pests

The following diseases and pests are most common:

• Fusarium. Fungal disease. Usually it develops at high air temperatures, high humidity, with dense soil, as well as lack of nutrition of bushes. To avoid fungal diseases, you can treat the cloves of garlic before planting. A solution of potassium permanganate and such drugs as Maxim and Fitosporin are suitable. You should study their instructions for use.
• Downy mildew. A disease that also occurs in hot weather and high humidity. In the fight against it, iodine milk, a decoction of horsetail, ash infusion help. These means spray the stems. Also use special drugs: Gamair, Vitoplan, Fitosporin-M. They must be used according to the instructions.
• Onion fly. A pest that infects leaves on bushes. If small worms are visible on the leaves, these may be the larvae of this insect. In this case, it is necessary to treat the leaves with saline. To do this, 200 g of table salt is dissolved in 10 liters of water.
• Stem nematode. This is a worm that lives long in the ground and lays eggs on plants. The best solution in this case is to destroy the plant and plant it on another bed next year.

Lack of trace elements

Potassium and nitrogen deficiency is often observed in the soil, resulting in garlic leaves turning yellow.

organic or mineral fertilizers. In mineral fertilizers, the concentration of nutrients is higher, so you should be especially careful with them, strictly follow the instructions. Top dressing is carried out in the spring. If you do this in the fall, the fertilizers will be washed until spring. You can also use the following solution: 20 g of urea in 1 bucket of water. Plants are watered at the rate of 10 liters per 1 m.

With potassium deficiency, foliar feeding is a good option. It is advisable to carry out the procedure at the very beginning of plant growth. You can apply a complex mixture. Potassium chloride is also used in a proportion of 10 g per 1 liter of solution. It is advisable that the weather be clear and calm. The product is sprayed onto the ground near the bushes.

Another option is the use of ash. Take 100 g of ash per 1 m. The solution is well suited for acidic soil. Manure is also used. It takes 100 kg of manure per 100 m of soil.

Conclusion

Yellowing of garlic is one of the problems many gardeners have to deal with. It is important to identify the cause of this phenomenon, then the fight against yellowing will give a result.
