Let's try to figure out why onion and garlic leaves turn yellow and what rules for planting and caring for crops must be followed in order to avoid these troubles.
Early frosts
There are times when gardeners follow all the rules and dates for planting, but the leaves of garlic and onions still turn yellow. The reason may be a sudden drop in air temperature. Such negative changes in weather conditions negatively affect young seedlings. However, do not be very upset - the sprouts will adapt to the cold snap, and the harvest will be saved.
Excess or lack of moisture
You should follow the rules for watering vegetable crops and remember that both a lack and an excess of moisture can cause problems for their growth and health.
With insufficient watering, yellowing begins at the tips of the leaves near the ground. If you notice that the soil is sticky and sticky, then you overdid it with watering. In this case, loosen the bed for faster drying.
Onions, taking into account sufficient natural moisture and the absence of drought, should be watered in summer 2-3 times a week at the rate of 10-12 liters of water per 1 sq. m beds. Garlic does not like moisture so much, so water it once a week, using 4-6 liters per 1 sq. m.
To get a rich harvest of healthy onions and garlic, approximately 3-4 weeks before harvesting, it is necessary to stop watering the crops.
Insufficient soil fertilization
If not only the leaves began to deteriorate, but poor growth in general is observed, and the feathers grow weakly, then the soil has a lack of nutrients due to poor feeding.
Fertilizers are an indispensable basis for good plant growth, protecting them from insects and pests. Top dressing is applied to the soil before planting root crops. Fertilization begins in September and continues until harvest. Fertilize the soil with humus or mineral agents based on nitrogen, potassium, phosphorus, etc.
It is RECOMMENDED during the growing season, which falls in late spring - early summer, to feed onion varieties with mullein or urea solutions.
The negative impact of diseases and pests
In addition to external factors, diseases caused by lack of pre-treatment of soils, such as fusarium, rust, various rot, black mold, etc. Affected plants, in case of detection of diseases, should be removed from the garden and destroyed.
Pests can also cause great harm to the crop. Of the most frequently infecting crops, one can single out the onion fly, onion moth, onion rattle, and various types of ticks.
In order to minimize the risk of insect damage to plants, it is recommended to pre-soak the planting material in fungicides and deep digging of the earth.
We hope that this article will help you understand the possible causes of yellowing of the tips of onions and garlic and avoid their occurrence.
