Why the leaves of the cabbage wither in the garden: what to do, how to water

The first ten days after planting cabbage seedlings in the ground is a difficult period, both for plants and for summer residents. Until the seedlings get stronger, they need to be covered for 5 days from the direct rays of the sun with any objects: covering material, old seedling boxes, buckets, boxes. If this is not done, the leaves of the seedlings in the sun can lose most of the moisture. The roots at this time are still weak and will not be able to provide the plant with the necessary moisture, the seedlings disappear.

Until the summer resident cuts down the cabbages, cabbage can be threatened by infections (keel, black leg), insects (aphids, cabbage fly, cruciferous flea, cabbage moth). In order not to be left without a crop, you need to identify pests and symptoms of diseases in the garden in time.

Why cabbage leaves wither

Kila is a very common disease of cabbage, both in the seedling stage and during its active growth. The main signs of quila can be seen on the roots. In diseased plants, seals form on the roots.

At the initial stage, the growths are painted in a pale yellow color, by the time the cabbage dies, they darken. Damage to the root leads to malnutrition of the seedling, it stops growing, the head does not form, the cabbage leaves wither.

What should a summer resident do and is it possible to save diseased cabbage

There is no point in treating if the club has affected seedlings or an adult plant. The disease is caused by a harmful fungus that persists in the ground for six years. The first thing a summer resident should do is to remove and burn all diseased plants.

Factors causing disease:

acidic soil;
high soil moisture;
soil heated to 20-25 °

Cultivation of cabbage on the ridge where the keel was found should not be practiced for 5-6 years. In autumn, the soil must be cleaned of all plant residues and disinfected. Use bleach for disinfection. The concentration critical for the fungus is 200 g per sq. m.

Spring preventive measures

Plant seeds for seedlings in purchased soil. Garden soil is very likely to contain keel spores. So that the future plant does not disappear, treat the seeds with a solution of manganese and only then sow. Cabbage ridge, where there was a keel, plant with tomatoes, peppers or garlic. Nightshade crops can cure the soil of quila in 3 years. Plant seedlings of cabbage instead of potatoes or tomatoes.

List of spring prevention activities:

spill a few days before transplantation with Bordeaux liquid (1%);
prepare milk of lime from water (10 l) and lime (1 glass), pour 0.5 l into each well;
all summer on the ridge with cabbage to loosen the ground.

Why seedlings wither

Because of the black leg, summer residents often die seedlings not only of cabbage, the disease affects flower crops, tomatoes. You can suspect the disease if, for some unknown reason, cabbage seedlings wither, fall, and thinning appears in the root zone. The reasons for the appearance of a black leg can be different.Starting with planting fungus-infected seeds.

Summer residents often take land for seedlings in their gardens, and it may contain a pathogen. Overcrowded planting and improper seedling care are very common causes of fungal infection.

When an inexperienced gardener sees that the cabbage is withering, he, first of all, begins to water the seedlings. This is a gross mistake, if the seedlings withered, this does not mean that it needs water. Overwatering can cause infection to spread.

When the cabbage wilts, they check the soil moisture, inspect the roots of the plant. The root system affected by the fungus is easy to recognize. Thin fibrous roots are absent, the root is not developed, dark in color, there may be signs of decay. Immediately after the diagnosis is made, all seedlings affected by the blackleg must be dug up and destroyed.

If the cabbage is sick with a black leg, it can no longer be cured. Save the remaining seedlings. Pour the boxes with seedlings with a pink solution of potassium permanganate and take them out to a cool room. Provide seedlings with full coverage, spray with Epin to stimulate local immunity.

Prevention

Blackleg prevention is the most effective way to fight for he althy seedlings. Prevention measures are not difficult:

treat seeds before planting with fungicide or manganese solution;
sow in soil treated with steam, temperature or fungicide;
if sowing seedlings is carried out in the ground taken from the garden, then do not take it from cabbage beds, take it from tomato or potato;
seedlings with a diseased root system should not be planted in the garden, it is subject to complete destruction.

Why cabbage leaves turn yellow and wither

Young plantings of cabbage look terrible. Recently planted seedlings withered, its lower leaves are all covered with small holes. If you look closely, you can see the reason - a small black insect cruciferous flea.

If no control measures are taken, insects can kill young cabbage seedlings in a few days. Leaves damaged by insects dry out. Some summer residents use chemistry, others choose less toxic methods of struggle, use folk recipes.

Folk methods are effective if the seedlings are only slightly wilted and the disease is caught at the very beginning. You should always have an infusion of tomato tops or dandelion roots ready. Spray them on every bush. Sprinkle the earth around the seedlings with ash or tobacco dust.

Chemistry is not contraindicated. The cabbage is still young, the heads of cabbage are just beginning to wrap up and, without consequences for their he alth, they can be sprayed with any of the preparations: Intavir, Commander. The rain that has passed after treatment washes away all traces of the drug, so the cabbage leaves are re-sprayed.

Aphids on cabbage

After the protracted summer doges, when the sun comes out, you need to carefully examine the cabbage leaves. When the weather changes, they can be attacked by aphids. This insect will not be able to destroy an adult plant. The leaves do not dry, but their quality is reduced. Aphid colonies settle on the back side of the leaves, to see the insect, you need to turn them away.

You need to fight aphids in simple ways without the use of chemistry. The leaves can be washed with ordinary water by directing a jet from a hose at them. Wash the ground under the bushes and powder with a layer of wood ash. After 2 days, repeat the treatment.

Saving the crop from the cabbage fly

The summer years of the cabbage fly can destroy the harvest, it happens in mid-June. Flies lay their offspring on cabbage leaves. Larvae, hatching, live in the root, gradually damaging it. Pest-infected cabbage becomes lethargic. The leaves take on a bluish tint. It is difficult to understand why the plant stops growing, since the larvae are difficult to find, they are small.

To protect the cabbage from the fly, a number of preventive measures should be taken in the spring:

treat seedlings before transplanting with Topaz solution (1 ampoule per bucket of water);
when preparing the ridge, apply Zemlin preparation (3 g/sq.m.) to the ground;
during the summer of cabbage flies, cabbage leaves 2 times treated with Spark, the interval between treatments is 7 days.

In June, when cabbage fly years are possible, experienced gardeners advise raking the soil from the stem and replacing it with another. Some people sow tansy, coriander, marigolds between cabbage rows to scare away a harmful insect.

A special transparent mesh can be purchased at the gardening store. The fly will not be able to penetrate the cabbage if the net is stretched over the bed and pinned along the edges. In the rain, the net can be removed, as the fly does not fly in such weather.

Copper sulphate helps with many pests. Based on it, you need to prepare a soap solution. Dissolve 1 tbsp in a bucket of water. l. soap shavings, take tar soap and a tablespoon of copper sulfate. Spray leaves at 3 week intervals.
