My Grape Leaves Are Turning Yellow in June

Why do grapes have pale leaves?

Nitrogen starvation

Many summer residents ask questions why the leaves of grapes brighten, what to do and how to feed the plant. This is not accidental: deficiency of mineral substances becomes a frequent cause of lightening foliage. The problem is solved by the introduction of certain fertilizers. Nitrogen starvation is the most common disease of grapes.

With a shortage of nitrogen in the bush there are light green leaves: first, the veining, then all leaf blades in the lower part of the plant turn pale, the petioles turn red. If you do not feed the bush, it will gradually turn pale, later it will turn yellow and brown. It is necessary to add complex mineral fertilizer with nitrogen, potassium and phosphorus to the feeding zone of the vine; urea; humus. So, urea is applied to the soil in the form of a solution (30-50 g per 10 l of water) and additionally used for spraying (1% solution).

Iron deficiency

Iron deficiency is another common reason why pale leaves are in grapes. The plant has developed chlorosis, that is, chlorophyll is poorly formed in the foliage.At the same time lose juicy green color and shoots, and the bleaching of the vine occurs from the bottom top.

Iron deficiency is compensated by spraying the bush with iron sulfate (0.2% solution is enough). If the deficit is not replenished, the grape harvest will become scarce, the neglected vine will stop producing fruit.

Excess lime in the soil

The reason for the pale leaves of grapes can be bad weather, cold and rain. If there is an excess of moisture, the bush lacks air, the plant may even rot. If there is a lot of lime in the soil, an alkaline reaction may begin under the influence of water, as a result, the grapes will receive less nutrients, the same iron.

The plant falls ill with lime or carbonate chlorosis. With the stagnation of water should arrange drainage, for example, from rubble. As a treatment, fertilizer is applied that does not increase the alkaline reaction in the soil, for example, ammonium sulphate. To feed, you need a complex of fertilizers with substances that will help the grapes better absorb iron: boron, zinc, manganese, magnesium.

Lack of lighting

Sometimes pale grape leaves and shoots - just a consequence of poor light.The plant must be given more light, and as soon as possible! This requires thinning high vegetation, remove obstacles that cover the grapes from the sun's rays.

You may need a cardinal solution - transplanting a bush to a more suitable place for this variety. When growing plants in the greenhouse will need to equip the room with additional lighting.


If in the area of ​​the plot where the vine grows, it suddenly suddenly became cold, this can also be an explanation of why the light green leaves of the grapes, which used to delight in lush green thickets. This happens if the foliage barely had time to form, and then frost hit.

Leaf blades that survived the cold may lose their color completely and become spotty. Affected leaves are recommended to be removed.


Grape leaves begin to brighten, with yellow streaks appear? It is possible that the grapes caught infection. Often the disease of this plant is caused by a spotted mosaic virus, which is transmitted by roundworms. Diseased leaf blades become stained, curled and dry.

A sick bush needs to be urgently uprooted and burned away from the plot, and the soil should be disinfected from roundworms - steamed or treated with special means according to the package instructions. So, you can use an aqueous solution of Fitosporin (15 ml in 10 l of water). Ecstrasol, Barrier, Glyocladin, insecticides Iskra, Aktara, Inta-Vir and others also fight well against soil pests.

Fungus injury

The light green leaves of the grapes, together with pale and yellow spots, flying over the foliage can be signs of a fungal infection of the bush. Most often, the plant is ill with powdery mildew (mildew). In neglected condition, the disease affects the clusters, they become brown in color, the blue rim around the peduncles.

It is necessary to prevent the defeat of the grapes with a fungus: do not plant a vine in a lowland, wetland, make sure that the bush is well ventilated. If the first signs of mildew are noticed, treat the plant with special compounds, for example, Topaz. The so-called Bordeaux fluid, a solution of blue vitriol in calcareous milk, has proven itself in the fight against mold fungi.The easiest way to buy ready-made concentrate is to pour it into the sprayer in the recommended proportion.

As you can see, the reasons for lightening the leaves of the grapes can be more or less innocuous. Regular care of the vines, timely feeding and attention to the garden are sure to help you collect a good harvest of fruits.
