Why balcony cucumber leaves are stained and what to do

As soon as the sun begins to warm, the human body needs a lot of vitamins. Among the first vegetables used in salads are cucumbers.

And if it is not possible to grow vegetables in the summer cottage, you can get them from plants on the window or on the balcony.

Varieties for balcony growing

Popular varieties of cucumbers for growing on the windowsill include those that do not form long lashes, give high yields, and are resistant to diseases:

Boy-with-finger cucumbers ripen forty days after planting seeds.The hybrid has long lashes, but they do not differ in branching. The fruits of the vegetable reach ten centimeters in length, have tubercles with small spikes on the skin. Crispy greens have an excellent taste.
Mazay variety belongs to the early ripe ones. Cucumbers are quickly tied up and give small-tubercular fruits in June. Seedlings have been prepared since March.
Hybrid Natasha grows well on the balcony, but the plant needs pollination. Cylindrical cucumbers are suitable for fresh consumption and pickling.

Powerful stems of the Masha variety are capable of braiding the walls of the loggia, and each knot will tie up to seven fruits, tasty, crispy.
The yield of cucumbers Rodnichok is up to seven kilograms per square meter.
City cucumber was created for growing in an apartment. Strongly branched stems are compact. The plant bears fruit well until the very cold.

Balcony miracle - a special variety for growing in an unconventional way. It is undemanding to growing conditions. The plant feels great in a pot. The ovaries do not dry from lack of moisture, soil. The vegetable bears fruit massively fifty days after sowing.

For growing cucumbers on the windowsill, it is best to choose parthenocarpic species containing female flowers. From the ovaries, the fruits develop successfully, since they do not require pollination. Those varieties of vegetables that need pollination by insects do not grow.

Growing quality seedlings

In addition to choosing a variety of cucumbers, the preparation of seedlings plays an important role. Cucumber seeds undergo a disinfection procedure before planting in the ground, they are dipped for thirty minutes in a one percent solution of potassium permanganate. The age of the seeds is important in obtaining a crop of greens. Take five-year-old seeds of the plant, as they will produce the most female flowers.

Peat cups or tablets are suitable for planting cucumber seeds. The seeds are immersed one and a half to two centimeters deep into the soil.In order for the seedlings to hatch faster, the plantings are watered abundantly. The containers are placed in a warm room with an air temperature of 25 degrees above zero. Lower the temperature to 18 degrees after the first sprouts have hatched. Young shoots of cucumbers that have appeared require:

abundant watering;
daily spray;
organization of lighting with fluorescent lamps;
fertilization.

With well-organized conditions, seedlings will develop quickly.

Vegetation of cucumbers on a window or balcony

Vegetables grown on a balcony or window go through the same stages of development as in greenhouses, open ground. It is important to choose a container for cucumbers on the balcony.

The roots of the plant do not differ in deep occurrence, so a container for vegetable seedlings with a diameter larger than the height is useful.

Continuing to grow cucumbers on the windowsill, they are not satisfied with the stress of transplanting. Indoor cucumber feels great. For him, create a humid climate by spraying and daily watering. Plants need top dressing every ten days. Special fertilizer complexes for cucumbers are suitable.

After the appearance of the fifth leaf, support is organized for the stems of the plant. A net is stretched along the window and lashes of cucumbers are tied to it.

If the seedlings received the nutrition they need, light, heat and moisture in sufficient quantities, then there will be no barren flowers and the fruits will set. You can increase the number of cucumbers on the shoots by pinching the top after the seventh or eighth leaf. On the resulting lateral lashes, female flowers are formed.The set fruits grow quickly. Daily picking of greens encourages the formation of new cucumber ovaries.

Balcony vegetable plants go through stages of development in the same way as in the open field. They ripen on time if the conditions for their cultivation and care for them are in compliance with the cultivation technology of cucumbers.

To support the lashes, they stretch a rope on the balcony to which the shoots are tied.

Form bushes of cucumbers, pinching the top after the appearance of the eleventh leaf. On growing lateral shoots, pinching is done above the second leaf, on the next - five or six leaves are left.

Why the ovaries turn yellow on cucumbers, what to do

Gardening is not always satisfying. You need to learn the technology of growing cucumbers before you get crispy greens in a mini garden organized in an apartment or balcony.One of the common problems is when fruits do not set or the ovaries fall off after yellowing. There are several reasons for this state of the plant:

The absence of mineral elements in the soil leads to yellowing of the ovaries of cucumbers. Lack of nitrogen is manifested by lightening of the leaves. You can improve the soil with special mixtures, which are laid out in a layer of fifteen centimeters.
Reducing the temperature at night leads to hypothermia of the plants. Cucumber grows and develops poorly. Do not wait for the fruits from him.

Both seedlings and adult plants are watered with warm water. Waterlogging the soil threatens that cucumbers will not bear fruit. And the dryness of the air and the earth will not allow the development of ovaries in cucumbers.
Lack of light for plants at the window will result in empty flowers growing on the stems.
If there is not enough space on the windowsill, do not try to plant all your favorite varieties of cucumbers. For vegetables to grow comfortably, they need an area of \u200b\u200bhalf a square meter. Then there will be enough light and nutrition, and yellowing of the ovaries will not occur.

If a large number of fruits set, this will lead to the shrinkage of cucumbers, their drying. For a normal harvest, twenty-five ovaries will be enough. Do not leave flowers in the lower axils of the leaves, they will draw off most of the nutrients.

Yellow spots on the leaves may appear as a result of cucumber diseases. When infected with a fungus, cucumbers grow weakly. Even if the vegetable bloomed and the fruits were tied, the plant will not give cucumbers. Common plant diseases include:

fusarium;
powdery mildew;
white rot;
brown spotting.

It is known why balcony cucumbers have spotted leaves. Fungi place spores on leaves. And pests of cucumbers also affect this part of the plant. Developing diseases end with the death of the plant.Therefore, it is necessary to organize the prevention of infectious infection. And if signs of pathological development are found on cucumbers - their treatment. Diseases of cucumbers are cured after the treatment of plants with fungicidal preparations.

Signs of cucumber diseases

Cucumbers are more likely than other garden crops to suffer from diseases:

White rot affects all parts of the plant. An infection occurs with high humidity in the room and diligent watering. Fungus spores are visible inside the cucumber stem. They are transmitted through human hands, air. Fungus spores can fly into an open window and settle on the leaves of cucumbers. It will help to get rid of the disease by removing the affected parts, powdering them with lime or crushed charcoal.
White blooms on the leaves are a sign of powdery mildew. When the first signs of illness appear, cucumber leaves are pollinated with sulfur powder or the plants are treated with Fitoverm.
Brown spotting on the leaves appears with a sharp drop in air temperature. Over time, the spots turn into ulcers. You can prevent the disease by raising the air temperature to 20 degrees Celsius, reducing humidity. The treatment of cucumbers with Bordeaux liquid eliminates the signs of the disease.

The development of pathological conditions of cucumbers occurs due to non-compliance with the rules of care. Plants need ventilation, so cucumbers that are planted densely often get sick.

Why don't cucumbers bloom

If the seedlings of cucumbers developed correctly, then thirty to forty days after planting the seeds, flowers will appear. When flowering does not occur, there is a reason why cucumbers do not bloom.

To avoid this situation, you need to:

water cucumbers with warm water in the morning or evening;
plant vegetable seedlings at a distance of twenty-five centimeters from each other;

remove shoots and buds in the axils of the lower leaves;
purchase vegetable seeds from trusted manufacturers;
feed with complexes containing potassium and phosphorus, excluding nitrogen before flowering;
disinfect soil before planting seeds;
add chalk or slaked lime to the soil.

To prevent the problem of lack of flowering or the appearance of empty flowers, seeds of parthenocarpic varieties or self-pollinated hybrids are purchased. And then the question: “why the ovaries fall and turn yellow” will not bother you.
