Spraying cucumbers with vinegar can provide the plants with sufficient nutrients, promoting their growth and development. In addition, vinegar also has a certain bactericidal effect, which can prevent and reduce the occurrence of cucumber diseases. Spraying cucumbers with vinegar is generally done during the vigorous growth period and the flowering and fruiting period.
Best time to spray vinegar on cucumbers
1. Peak growth period
During their vigorous growth period, cucumber plants require a large amount of nutrients to support their rapid growth. Spraying vinegar at this time can provide them with sufficient nutrition, promoting dark green leaves and thick stems, which is beneficial to improving cucumber yield and quality. At the same time, spraying vinegar can also enhance the disease resistance of cucumber plants and reduce the occurrence of diseases.
2. Flowering and fruiting period
During the flowering and fruiting period, cucumber plants require more nutrients to support flower opening and fruit development. Spraying vinegar at this time can promote flower opening and pollination, increasing fruit set rate. Simultaneously, spraying vinegar can also promote fruit development, improving fruit quality and yield.
Method of spraying vinegar on cucumbers
1. Concentration and frequency
The concentration and frequency of vinegar spraying on cucumbers also need to be carefully controlled. Generally, the vinegar concentration should be controlled between 1% and 2%, and sprayed once every 5-7 days. If the concentration is too high, it may damage the cucumber plants. If the concentration is too low, it may not achieve the desired effect.
2. Water promptly
In addition, it's best to water the cucumber plants before spraying vinegar. This increases the plants' ability to absorb the nutrients from the vinegar, improving the effectiveness of the spray. Also, spraying vinegar is best done on a sunny morning to better promote its absorption and utilization.
3. Precautions
Spraying should be done around 3 PM on a sunny day, as the leaves absorb the vinegar quickly at this time, resulting in high utilization and good effects. Each time you spray, prepare a fresh solution; do not use previously stored solutions. Spray evenly onto the cucumber leaves until no water drips.
