How to feed the apple tree if the leaves turn yellow. What to do if the leaves turn yellow on apple and pear in summer

The change in the color of the leaves of apples and pears occurs for several reasons. Most often the tree lacks nitrogen, other macronutrients, moisture or light. Sometimes the plant has a damaged root system or a disease. How to cope with the yellowing of the leaves?

Often the leaves of fruit trees turn yellow throughout the summer. Initially, they are covered with small spots, shriveling, and then fade and fall off altogether. The reasons for the change in color can be several:

lack of macronutrients and nutrients
bacterial infections
temperature changes,
the activity of diseases and pests.

Consider each of the possible problems separately and talk about how to fix it.

Because of what leaves on an apple tree and a pear in June turn yellow

In recent years, the leaves of apple and pear begin to acquire "autumn" color at the very beginning of summer. This may be due to one of the following reasons.

Heat. If you did not water the plant with enough water, it could disrupt the nutrition of the roots and foliage. Therefore, urgently increase the intensity of irrigation at least to 1 time in three days.
Excess moisture. However, with irrigation should be careful - with an excess of moisture, the root system is flooded (most often this happens on heavy clay soil). In this case, the tree should be watered no more than 1 time per week.
Sunburn. If you watered the apple tree or pear abundantly on a hot day, and some of the water got on the leaves, it could cause burns and yellowing. In this case, you can feed the tree with an extract of mullein (dilute 1 cup of fertilizer in 10 liters of water) or spray the foliage with Zircon after sunset, so as not to burn the leaves again.
Herbicide exposure. If in the spring you carried out a massive pest and disease control, then probably some of the pesticides hit the leaves and caused them to die prematurely.
Moles. These small animals could dig up and damage part of the root system. If you observe earthen mounds on the plot, then it is time to get rid of moles.

Spray herbicides carefully, as some of the substances fall on the leaves of fruit trees.

Why do leaves on young apple and pear turn yellow

It is especially annoying to watch the leaves turn yellow in young trees, which should be pleasing with fresh greens and bright colors. There may be several reasons for the "autumn mood" of apple and pear.

Root penetration. Perhaps, when planting, you planted seedlings too deep, and the root neck was 10-15 cm below the ground level. Such planting gradually weakens the tree, it develops poorly and bears little fruit. In this case, it is easier to uproot it and plant a new apple or pear tree.
Close location of groundwater. Prolonged waterlogging also leads to the oppression of the tree and the fact that the root system stops breathing. Formed so-called "gley horizon", in which accumulate compounds of iron and manganese, poisonous for most plants. You can try to transplant a tree with a big lump of earth to a new place.
Sulfur and iron deficiency. If not only the apple tree or pear turn yellow, but other plants nearby, they may lack sulfur or iron. The deficiency of these microelements is observed with the excessive introduction of ash or lime. Neutralize them with sulfate or ammonium nitrate.
Scab develops. If this disease occurs 3-4 times per season, the tree should be treated with the drugs Skor or Fitosporin in accordance with the instructions. After watering (3-4 buckets of water), feed the tree with a nitroammofoska (one matchbox per 10 liters of water) at the rate of 2-3 liters of solution per plant.

With magnesium deficiency, the edges of the leaves become dark purple in color.

Why on the apple and pear turn yellow and fall leaves

Often the leaves do not just turn yellow, but also fall off after a while, depriving the tree of food. Diseases and pests are usually to blame for this.

Chlorosis of apple and pear. This disease is caused by prolonged drought, flooding of the site, leaching of organic and mineral substances from the soil and its depletion. First of all, it is necessary to strengthen the "nitrogen nutrition". For example, to feed a tree with ammonium sulfate or urea (35 g per 10 liters of water, make 3-4 liters under the bush) . Also useAzotobakterin (2-3 bottles of the drug under the same tree). Antikhlorozin is sometimes used (100-120 g per 10 l of water) for treating the roots, or if a pear is ill, spraying is carried out on the leaves and shoots.
Tick attack. Thinning and leaf fall can cause small mites (brown and red fruit). They feed on the juice of young leaves and are resistant to most drugs from pests. It is recommended that trees be sprayed with acaricides (Neoron) and insectoacaricides (Karbofos, Karate).

With the strong development of chlorosis, the root system dies off.

Why leaves and leaves turn yellow and dry on apple and pear

Sometimes during the summer, leaves of apple and pear trees turn white and dry, and then they dot the ground with a solid “dry carpet”. And this is not a sign of an imminent autumn, but a consequence of one of the following reasons.

Monilioz. This disease is manifested not only by yellowing leaves. During its development, the whole tree looks as if it has been burned with fire - twigs and other parts become dry and lifeless. Moniliasis usually occurs 2-3 weeks after flowering, and its peak occurs in August. After flowering, the plant should be treated with any antifungal drug, 1% solution of Bordeaux mixture, or copper chloroxide (30-40 g per 10 l of water).
Bad stock. Due to the incompatibility of grafted plants moisture and nutrients do not flow to the branches of the tree. In this case, practically nothing can be done, it remains only to hope that the next time the vaccination procedure will be more successful.

When moniliose leaves quickly change color from yellow to dark brown and soon die

Because of what the leaves on the apple and pear turn yellow and curl

The leaves of apple and pear are subject to many diseases and negative external factors. Therefore, if they began to turn yellow and then curl, then the following problems may be the cause.

Calcium deficiency. Young leaves brighten and twist upward, growth points die off, and the leaves soon fall off. When symptoms of calcium deficiency appear, the acidity level of the soil should be checked and limeed when the pH level is exceeded (the normal level for most fruit trees is 6-7 pH). At a normal pH level, trees are fed with calcium sulfate.
Freezers. When the root system freezes, not only is its depression, but also the trunk, branches, shoots, and leaves. The latter become small, turn yellow and curl. In this case, watering the trees with a solution of urea (500 g per 10 liters of water) will help, as well as a mixture of mullein with clay, which covers the wounds formed on the trunks under the influence of low temperatures.

When a frostbite is formed, the foliage may turn yellow closer to the middle of summer and rapidly fall off.

Causes of yellowing of the leaves on seedlings

Even outwardly healthy seedlings may suddenly turn yellow. This may be due to poor quality planting material or be caused by one of the following reasons, which manifest themselves after planting.

Lack of nitrogen. In the early stages of growth and development, young trees are most severely affected by nitrogen deficiency. Be sure to bring humus (4-5 kg per 1 sq. M circle wheel) and close it to a depth of 35-40 cm.
Critical temperature drops. If you planted an apple or pear tree too early, or frost occurred in the winter after a thaw, the young tree may freeze. To prevent this from happening, in the fall, the shtamb should be tied with a warming material — coniferous spruce branches, sackcloth, and cloth.
Stem damage. At the base, on the border of the trunk and root system, the tree could damage mice and other rodents. In this case, the spreading of wounds with a thick clay talker can help (the damaged areas are cleaned to a healthy tissue, covered with a clay talker and wrapped with cotton cloth) or grafting with a bridge. It is better to refuse planting a partially damaged seedling, since the tree will still be sick and bear fruit poorly.

Sometimes the leaves are yellow right on the seedlings - it is better not to buy such copies

How to process the trees on which the leaves turn yellow

A universal remedy for treating trees on which the leaves turn yellow is bordeaux mixture. For its preparation, you need to mix 100 g of copper sulphate, 100 g of lime and 10 liters of water. Spray should be 1 time in 2 weeks.

Spraying also helps calcium chloride (25-30 g per 10 liters of water). If the leaves gradually become gray and their edges turn brown, this indicates iron deficiency. In this case, use the solution iron sulphate(60-80 g per 10 liters of water). During budding, budding, during flowering, as well as in July-August, a solution is used to control pests. colloidal sulfur (100 g per 10 liters of water).

Now you know all about the causes of yellowing of the leaves on the apple and pear. Only your timely and quick actions, as well as the right drugs and solutions, will help prevent serious diseases and save your suddenly yellowed trees.

The first mentions of the apple appeared more than 5 thousand years ago. Probably, even then our ancestors appreciated the benefits of this plant. Nowadays it is one of the most popular fruit-bearing trees among summer residents and gardeners. Apple trees not only delight the rich harvest in the fall, but also turn the site into a truly flourishing fairy kingdom in spring.

Of course, in the care of a tree sometimes there are problems. Like any other plant, it is prone to disease. One of the first symptoms of the disease is the deformation and shrinking of the foliage.

Leaves curl on an apple tree: what to do?

If foliage is affected on an apple tree, the cause may be aphid. After twisting, the leaves fall, the tree becomes bare. Young shoots bend and dry. A large cluster of aphids can be found at the ends of the branches. You can fight the pest with the help of chemicals (Konfidor, Spark) and popular methods (decoction of wormwood, garlic decoction). A hunter belt is quite popular among gardeners: a garden pitch is applied around the base of the tree, covered with polyethylene on top. It should not touch the trunk. From above fix an elastic band. The hunting belt does not allow ants carrying the aphid larvae to penetrate the tree crown.

Another reason for twisting the leaves of an apple tree is powdery mildew. The leaves also begin to crumble, flowers and buds are covered with gray bloom. You can fight the disease with a one-percent solution of colloidal sulfur.

Dry leaves on an apple tree: the reason

In a situation where the leaves on the apple tree dry up, winter frosts or rodents, eroding the roots, may be to blame. Moniliosis contributes to drying. This fungal disease occurs a few weeks after flowering or in August. Especially if there is cool or wet weather outside the window. Symptoms of the disease - wilting and drying, brown leaf color. To combat the disease before flowering, treat the plant with any antifungal agent (Alerin, Fitosporin) or copper sulfate solution. After flowering - copper oxychloride. In order for the apple tree to resist the fungus, it is necessary to prune the affected shoots, including 10–15 cm of healthy tissue, to remove rotted fruits from the branches in the fall.

Red spots on the leaves of an apple tree

Red spots on the leaves of an apple tree indicate the possible presence of the fungus Sphaeropsis malorum - among the people of black cancer. Immediately after bud break, small reddish specks begin to appear on the leaves of the plant, scattered all over the surface. Over time, they increase to 4-6 mm. Spores can be found under the skin in the center of the spot. They are visible to the naked eye - they are black dots.
Usually, bark suffers from black cancer, so to save the tree from the disease, it is necessary to cut sore spots, process them with copper sulfate and cover them with garden pitch. The mass invasion of black cancer can be caused by drought, heavy rainfall. Young apple trees, unlike the old ones, are fairly resistant to fungi. Prevention may be whitewashing the trunk in the fall, pruning and destruction of diseased and dry branches.
Red blotches appear due to the red-gall aphids. After the appearance of spots on the apple leaves curl, red growths are formed, the disease passes to the fruit. Before budding, the tree should be treated with any preparation from the larvae of aphids (Oleukuprit, Nitrafen, Kemifos). If krasnogallyovka looked into your garden during the formation of the fruit, it is better to spray apple infusion of tobacco dust.

Apple leaves: useful properties

A change in the color of the leaves of an apple tree, their deformation may be due to other reasons. One of the main ones is the lack of necessary trace elements. Lack of nitrogen and magnesium leads to yellowish and sometimes reddish shades of foliage. Painful symptoms may be associated with phosphorus starvation, lack of potassium, boron, calcium.

Fighting diseases of the apple is necessary not only to preserve and improve the quality of the fruit. The leaves of the tree have significant beneficial properties. The effect of tea and decoction from them on the human body is due to the high content of vitamin C and phenolic compounds that strengthen the walls of blood vessels. Apple leaves help cure colds, cough, reduce the amount of cholesterol in the blood, are used for problems of the gastrointestinal tract, help get rid of acne.

Broth taken with anemia and insomnia. As a vitamin, you can use the tincture of fresh leaves. In other cases, tea is dry. Harvesting raw materials is better in June or July. The leaves are dried under a canopy, occasionally turning, or subjected to heat treatment (40-50 degrees). Willingness is determined by the fragility of the stalks. They should not bend.

the presence of a huge number of any pest;
diseases of the leaves.

All of the above can cause, both alone and together, the yellowing of foliage in the crowns of apple trees.

Diseases

Apple tree exposed diverse leaflets. This is fungal the rot and contagious diseaseswhich are found not only in the form yellowed leaves, but also little black spots on them.

in the spring, before flowering, and even before the appearance of flowers, a good treatment from copper sulfate and calcium hydroxide. To avoid the outbreak of diseases that can interfere with normal flowering;
when apple trees bloomed apply Trifloxystrobin or Difenoconazole. The same "chemistry" should be used in years with maximum precipitation.

Tip!Early detection of rot is the key to successful infection control.

Pests

shortage phosphorus will give early leaf fall from the bottom of the shoots. Therefore, it is necessary to boil a glass of superphosphate in a liter of water, 15 minutes, and dissolve the remaining liquid with water up to 8 liters. This solution is enough for one large apple tree or 5 dwarf trees;
shortage magnesium- leaves of a light grass color, with a lilac nuance along the veins. And then it is necessary either to add magnesium fertilizers to the soil of the stalk strip, 67–110 grams of magnesium per each adult tree. Or sprinkle the crowns of apple trees with a complex of compounds, where magnesium is the most, “on the leaf” and strictly according to the instructions, at night.

Do as he did, and he has apples about -go-th. And the fact that his garden is to the south is different varieties and the care is not the same, this statement is not taken into account. So it turns out that they advise, all and sundry to feed the apple tree. But here is the science of agricultural chemistry does not advise doing this for cold regions and acid thin soil. And that's why:

it not hygienic;
There is danger just burn suction rootsincorrectly calculated volume of slurry;
For apple trees so fast nitrogen after July is detrimental. For it will stop the ripening of the branches, and their excessive growth will greatly reduce the frost resistance of apple trees. Therefore, you can feed it only until the end of flowering.

In the southern regions a bucket of humus on a tree up to 15 years old and three buckets if the apple tree is old.

In the northern regions growing apple orchards you need to completely refrain from such dressings, and replace them with top dressing potassium humate, in doses indicated on the label of the drug. Or apply manure compost, on the bucket on the young and on the three buckets on the old apple tree.
