Many gardeners, even experienced ones, complain that garlic leaves turn yellow on their beds early. The reasons for this phenomenon are many, in the article we will dwell on the most common of them.
Most often, such a phenomenon as yellowing of the tips of garlic tops is observed in winter crops. As a rule, this is due to improper fit, namely, if the teeth were too deep. The optimal planting depth does not exceed 5 cm. If the garlic cloves were embedded deeper, thorough loosening of the soil will help.
The leaves of this crop turn yellow due to obvious violations of the timing of planting in open ground. They need to be calculated so that the teeth have time to root well, but they do not start to grow. If the landing was correct, the first shoots will appear only in early spring. In order for the crops not to freeze, the beds are mulched to a thickness of 5-6 cm with humus.
Garlic leaves also turn yellow due to poor watering. Perhaps this is the most common reason. Between May and July, garlic should be watered regularly. First of all, this contributes to the formation of excellent green mass and large garlic heads.
Garlic leaves turn yellow from strong spring frosts, as well as from a lack of
soil of minerals such as potassium, magnesium and nitrogen. If there is a lack of nitrogen nutrition, then you can feed the plants with stale manure, diluted in water, urea or any other nitrogen-containing fertilizer. Replenishment of this particular mineral element is important because it is washed out of the soil very quickly, and even if top dressing was done in the fall, then by the time the first sprouts of garlic appear, it most likely will not remain in the ground. Therefore, in spring, nitrogen fertilizers must be applied to the soil.
Garlic leaves often turn yellow due to damage to the plant by diseases such as stem nematode or white rot. A nematode very often infects a plant in rainy, wet weather. In this case, gardeners are advised to carry out a series of measures aimed at preventing these diseases before planting. So, first you need to water the soil on the prepared beds with a solution of sodium chloride (per 10 liters of water, 2 tablespoons of salt). Pour onto 1 square. meter 3 liters of liquid. Boarding itself
the material must be treated with the following solution: 1 teaspoon of salt and 50 grams of chopped small fern leaves are taken per 1 liter of water. All mix and pour garlic cloves for 15 minutes, but not longer. Then, without washing, they are planted. Next to the garden, it is best to plant marigolds, coriander, mint, calendula. These plants repel the stem nematode.
It is important to follow the rules of crop rotation when growing garlic . Do not plant it where the onions or potatoes grew: they have common diseases and pests. It is recommended to return it to the previous site only after five seasons.
There is another little secret: if it was not possible to establish why the leaves of the garlic turn yellow, you need to feed the plant with any complex mineral fertilizer and increase the watering.
