Why do the leaves of balcony cucumbers dry out and turn yellow, what to do?

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

And if it is not possible to grow vegetables at your 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 a windowsill include those that do not form long vines, produce high yields, and are resistant to diseases:

• Cucumbers of the Boy-Thumb variety ripen forty days after planting the seeds.The hybrid has long lashes, but they are not distinguished by branching. The fruits of the vegetable reach ten centimeters in length and have tubercles with small spines on the skin. Crispy greens have an excellent taste.
• The Mazai variety is an early ripening variety. Cucumbers set quickly and produce small lumpy fruits in June. The seedlings have been preparing since March.
• Hybrid Natasha grows well on the balcony, but the plant requires pollination. Cylindrical cucumbers are suitable for fresh consumption and pickling.

• The powerful stems of the Masha variety are capable of entwining the walls of a loggia, and each knot will bear up to seven tasty, crunchy fruits.
• Productivity cucumbers Rodnichok up to seven kilograms per square meter.
• The city cucumber is designed for growing in apartment conditions. The strongly branched stems are compact. The plant bears fruit well until the coldest weather.

• Balcony miracle is a special variety for growing in an unconventional way. It is undemanding to growing conditions. The plant feels great in pots. The ovaries do not dry out from lack of moisture and soil. The vegetable bears fruit en masse fifty days after sowing.

To grow cucumbers on a windowsill, it is best to choose parthenocarpic species containing female flowers. The fruits develop successfully from the ovaries, since they do not require pollination. Those vegetable varieties that require pollination by insects do not grow.

We grow quality seedlings

In addition to choosing the variety of cucumbers, the preparation of seedlings plays an important role. Before planting in the ground, cucumber seeds undergo a disinfection procedure; they are dipped for thirty minutes in a one percent solution of potassium permanganate. The age of the seeds is important in obtaining a harvest of greens. Take five-year-old plant seeds, as they will produce the largest number of 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. Reduce the temperature to 18 degrees after the first shoots hatch. The emerging young shoots of cucumbers require:

• abundant watering;
• daily spraying;
• organizing lighting with fluorescent lamps;
• application of fertilizers.

Under properly organized conditions, seedlings will develop quickly.

Growing cucumbers on a window or balcony

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

The roots of the plant are not deep, so containers for vegetable seedlings with a diameter larger than the height are useful.

Continuing to grow cucumbers on the windowsill, they are not satisfied with the stress of transplanting. The indoor cucumber feels great. A humid climate is created for it by spraying and daily watering. Plants need feeding every ten days. Special fertilizer complexes for cucumbers are suitable.

After the fifth leaf appears, support is provided for the plant stems. A net is stretched along the window and cucumber vines are tied to it.

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

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

To support the lashes, a rope is stretched on the balcony, to which the shoots are tied.

Cucumber bushes are formed by pinching the top after the eleventh leaf appears. On growing side shoots, pinching is done above the second leaf, on the next ones five to six leaves are left.

Why do the ovaries on cucumbers turn yellow, what to do?

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

• The lack of mineral elements in the soil leads to yellowing of cucumber ovaries. A 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.
• A decrease in temperature at night leads to hypothermia of plants. The cucumber grows and develops poorly. You can't expect any fruit from it.

• Both seedlings and adult plants are watered with warm water. Overmoistening of the soil threatens that cucumbers will not bear fruit. And the dryness of the air and soil will not allow the ovaries to develop in cucumbers.
• Insufficient light for plants in the window will result in barren flowers growing on the stems.
• If there is not enough space on the windowsill, there is no need to try to plant all your favorite varieties of cucumbers. For vegetables to grow comfortably, they need an area of ​​half 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 are formed, this will lead to the cucumbers becoming smaller and drying out. Twenty-five ovaries will be enough for a normal harvest. There is no need to leave flowers in the lower axils of the leaves, they will draw off the bulk of the nutrients.

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

• fusarium;
• powdery mildew;
• white rot;
• brown spot.

It is known why balcony cucumbers have spotted leaves. Fungi place spores on leaves. And cucumber pests also attack this part of the plant. Developing diseases end in the death of the plant. Therefore, it is so necessary to organize the prevention of infectious infection. And if signs of pathological development are detected on cucumbers, treat them. Diseases of cucumbers can be cured after treating the plants with fungicidal preparations.

Signs of cucumber diseases

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

1. White rot affects all parts of the plant. Infection occurs when there is high humidity in the room and heavy watering. Fungal spores are visible inside the cucumber stem. They are transmitted through human hands and air. Fungal 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 and sprinkling them with lime or crushed charcoal.
2. White coatings on the leaves are a sign of powdery mildew. When the first signs of disease appear, cucumber leaves are pollinated with sulfur powder or the plants are treated with Fitoverm.
3. Brown spotting on leaves appears when the air temperature drops sharply. Over time, the spots turn into ulcerations. The disease can be prevented by increasing the air temperature to 20 degrees Celsius and reducing humidity. Eliminates signs of disease processing cucumbers with Bordeaux mixture.

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

Why don't cucumbers bloom?

If the cucumber seedlings have 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 prevent this situation from occurring, you must:

• water the 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, eliminating nitrogen before flowering;
• disinfect the soil before planting seeds;
• add chalk or slaked lime to the soil.

To prevent the problem of lack of flowering or the appearance of barren flowers, purchase seeds of parthenocarpic varieties or self-pollinating hybrids. And then the question: “why do the ovaries fall off and turn yellow” will not bother you.
