How to prevent and control excessive growth in cucumbers? These methods you need to master

Excessive growth in cucumbers is the phenomenon of leggy growth in cucumber vines. Leggy cucumber plants affect the growth of the plant, causing it to only flower without setting fruit, so the cucumber's nutrients cannot be concentrated in the fruits that have already set. This lowers the quality of the cucumbers and also easily triggers pests and diseases, causing a major drop in cucumber yield. But many friends have not yet found a way to prevent and control it. Below, the editor brings you methods to prevent and control excessive growth in cucumbers. Let's take a look!

1. Watering

When growing cucumbers, water them at the right time according to the growth conditions of the cucumbers and various conditions. The main purpose is to ensure soil moisture content and surface temperature. During the fruiting period, water at least once a week, and replenish water before and after each harvest to prevent leggy growth. After harvesting the top cucumbers, water promptly as well to promote the growth of new cucumber roots.

2. Topdressing

When nitrogen is sufficient, promptly supplement with phosphorus and potassium fertilizer. When topdressing, mix the fertilizer with water and decide the amount of fertilizer based on the planting area. Then topdress once every 1-2 harvests. In the middle and late stages, apply it together with farmyard manure when watering, about 1000 kg per mu. Pay attention to the application of nitrogen fertilizer, as one of the main causes of leggy growth is excessive use of nitrogen fertilizer.

3. Temperature

Unsuitable temperature is also one of the causes of leggy growth in cucumbers. The most suitable growing temperature for cucumbers is around 28 degrees. If it exceeds 30 degrees, it can very easily cause leggy growth. So we need to control the temperature around the cucumbers well and not let it exceed 30 degrees. The nighttime temperature can be lowered appropriately, which helps the accumulation of nutrients in the cucumber plant.

4. Humidity

Although cucumbers prefer water, the relative air humidity must not exceed 85%. If it exceeds this range, dehumidification work should be carried out immediately. Strengthen the ventilation of the cucumber field, especially in the evening, ventilate for at least one hour, because humidity is higher at night. This can appropriately reduce nighttime humidity, control the plant's growth rate, prevent leggy growth, and improve the rate of flowering and fruiting.

5. Tying the vines

When the cucumber vines grow to a certain length, we need to start the work of tying the vines. The first time, tie the vine to an upright pole. When it enters the vigorous growth period, the vine can be bent. The degree of bending depends on the length of the vine and the growth rate.

6. Preserving the cucumbers

When cucumbers begin to produce the first batch of fruits, the plant's growth will be somewhat restricted, so a relatively high fruit-setting rate must be ensured on the first batch of cucumbers. If the number of set fruits is insufficient, it can easily lead to runaway growth. Properly preserving the cucumbers can not only increase the yield of the first batch, but also prevent leggy growth in the plant. It can also promote early maturity, allowing an earlier market launch to recover costs.

The above are the methods the editor has compiled to prevent excessive growth in cucumbers. In fact, proper harvest timing also has a fairly good effect on preventing excessive growth. Because harvesting too late will hinder the plant's growth, so for plants that are growing wildly, you can harvest a bit later to control the plant's growth rate. That is all for today's introduction. This article is for reference only, and I hope it is helpful to everyone.
