One of the common reasons why cucumber ovaries turn yellow and fall off is a lack of light.
Cucumbers need sufficient light to grow and develop normally. Sometimes they can be shaded by other plants grown in the greenhouse, which results in insufficient light for cucumbers.
To avoid this problem, it is recommended to follow a certain scheme for planting cucumbers in a greenhouse, says Anastasia Kovrizhnykh .
For hybrid varieties of parthenocarpic cucumbers, it is recommended to plant 1-2 bushes per 1 square meter of area, and for self-pollinating varieties - 2-3 bushes per 1 square meter.
It is also important to trim the tops of the shoots, leaving them no more than 20-25 centimeters long, and remove excess leaves and side shoots to ensure proper plant development.
The right temperature regime: ideal conditions for strengthening the ovary
Temperature plays an important role in the formation and strengthening of cucumber ovaries.
At low temperatures (below +13..+15°C) or high temperatures (above +25..+27°C), the ovary may begin to turn yellow, dry out and fall off. To maintain the optimal temperature regime in the greenhouse, additional film covering can be used at night.
To ensure optimal conditions, it is recommended to maintain the temperature until the fruits appear in clear weather within the range of +22..+24°C, and in cloudy weather - +20..+22°C.
Micronutrient balance: how to prevent yellowing of ovaries
Deficiency of some microelements can also lead to yellowing and falling of cucumber ovaries. For example, deficiency of magnesium, calcium or boron can negatively affect the formation of ovaries.
To prevent this problem, it is recommended to regularly analyze the soil and supplement it with the necessary microelements.
For this purpose, you can use special fertilizers or add compost or humus to the soil.
Balanced Watering: The Importance of Regular and Proper Watering
Lack or excess of moisture can also lead to problems with cucumber ovaries. Lack of moisture can cause the ovary to dry out, and excess moisture can lead to rotting and falling off of the ovary.
To prevent these problems, it is recommended to water cucumbers regularly and evenly, taking into account the soil moisture. Do not allow the soil to dry out or become over-watered, maintain an optimal level of moisture.
Removing excess ovaries: how to ensure optimal development of cucumbers
Sometimes cucumbers can produce too many ovaries, which can lead to improper plant development.
To ensure optimal development of cucumbers, it is recommended to remove excess ovaries, leaving only a few of the strongest and healthiest ovaries.
This approach will allow plants to concentrate their resources on producing high-quality fruits.
