How long for cucumbers to grow?

  1. The female flower of the cucumber itself is composed of small fruits and flowers. At first, it will bear small fruits and then bloom. When the cucumber flowers wither, the fruits will begin to grow.
    According to the season, it can be harvested in about a week after flowering in summer, and about 15 days in spring and autumn.
  2. Cucumber has dark green stems, shiny skin, white thorns on the melon, and light green streaks on the top. The melon can be harvested (proper management, generally 7-12 days after flowering);
    In order to be fresh and tender, reduce nutrient consumption, and increase the number of melons harvested per plant, the tender melons, especially the root melons, should be harvested in time to prevent the melons from falling.

How to manage cucumber after flowering?

  1. Cucumber flowers usually bloom from 5 to 6 in the morning during the day, and the blooming time is 1-1.5 hours. The flower life can be delayed to the afternoon of the same day, and the male flower will fall off the next day. Under low temperatures and rainy weather, life will be longer. Can bloom normally.
    When the corolla is fully expanded, the pollen has the ability to germinate in the afternoon of the day before flowering, but the germination ability reaches the highest when it blooms.

The lifespan of pollen loses its vitality rapidly in the natural state 4 to 5 hours after flowering, and the lifespan is short when the temperature is high.

  1. Cucumber flowering is closely related to temperature, and within a certain range, the higher the temperature, the more it can be promoted. Flowering usually starts at 60°F.
    The temperature limit for pollen germination is between 50°F-100°F, and the optimum temperature is 60°F-80°F. The pollen tube of cucumbers can reach 2 to 3 mm 4 to 5 hours after being pollinated. Cucumbers are basically monoecious but different flowers, and occasionally bisexual flowers appear.

What should I do if the cucumber does not bloom and bear fruit?

The reason why cucumber does not bloom:

  1. There are too many small fruits left during the planting process. Anything that can bear small fruits is left, and the extra female flowers are not removed.
  2. Improper fertilization. Excessive use of compound fertilizers makes the soil solution concentration too high, weakens the absorption capacity of roots, and affects the normal growth of plants.
  3. Excessive use of drugs. In the prevention and control of plant diseases and insect pests, some gardeners only pay attention to the prevention and control of chemical agents but ignore agricultural measures. The interval between the application of the agents is short and the concentration is severely exceeded, causing phytotoxicity. In addition, the indiscriminate application of hormonal pesticides causes physiological disorders of cucumber plants and causes cucumber growth points Can’t grow normally.
  4. Improper watering. Watering does not pay attention to weather conditions, nor does it analyze the pros and cons of watering according to plant growth rules.
    If it encounters unfavorable weather such as continuous cloudy, low temperature and strong cold current after watering, the ground temperature will be lower than 55°F, and the relative humidity of the soil will be higher than 85%, which will cause cucumber ratting, which will inhibit the growth of the root system. The growth of the upper part is more affected.
  5. The harvest is not timely. Because of being too busy, they did not pick them on time, leaving the grown melons on the melon seedlings, causing waste.
    The result of this is to break the balance between plant vegetative growth and reproductive growth, causing excessive consumption of organic nutrients in the plant.

Measures for Cucumber Flowering but Not Fruiting

  1. The blades should be evenly distributed. Cucumber plants are maintained at a height of about 1.5 meters, and ensure that there are more than 15 functional leaves (used to absorb sunlight) on the plants to ensure normal photosynthesis and maintain normal growth.
  2. Pay attention to thinning flowers and fruits. For plants with a lot of sitting melons, the melons should be thinned properly, and the melons should be kept if they are not visible, otherwise, it will easily cause seedling breakage in the middle and late stages. The yellow leaves at the bottom should be removed in time to reduce consumption.
  3. Strengthen light management on cloudy days. When the grass is pulled out near noon on a cloudy day, if the wind is properly released for 2 hours, not only will the shed temperature not be reduced, but it will increase by 35°F. After the cloudy sky suddenly turns clear, the grass thatch can’t be opened suddenly.
  4. Pay attention to fertilizer and water management. When the temperature is low and the light is weak, the watering frequency should not be too frequent. Generally, water should be watered once in about 20 days, and flooding is not allowed.
    Also note that after watering, wait for the temperature in the shed to rise above 85°F before letting out the air, and the air outlet should be from small to large, and not too big at one time.
    Fertilizers are generally flushed with water. Fertilizers containing humic acid or amino acids that are easily absorbed by cucumbers should be used. Do not use too much at a time.
  5. Strengthen disease control. Because the prevention is not timely, it is very easy to cause phytotoxicity after using the medicament in the shed. Therefore, when using the medicament, the concentration of the use must be strictly controlled. Do not mix multiple types of medicaments to reduce the occurrence of phytotoxicity.
