How to make cucumber seedlings strong

1. Increase lighting

Cucumbers need sufficient sunlight to grow. The daily lighting time should not be less than 8 hours, which can accumulate a large amount of nutrients for the plants and help the cucumber vines grow thicker. If greenhouse cultivation cannot meet this standard, fill lights can be used to provide lighting.

2. Lower the temperature

Although cucumbers can grow under high temperatures, low temperatures can inhibit their respiration and effectively store nutrients. The temperature during the day can be controlled at around 32℃, but it should be lowered to 15-18℃ at night, and maintained at 10-12℃ in the second half of the night, which will help it expand.

3. Raise ground temperature

Suitable ground temperature can make the cucumber root system more developed, which is conducive to the absorption of water and nutrients, and can also make the cucumber vines thicker. The suitable ground temperature is around 18-24℃. If it is lower than 8℃, the roots will no longer grow. Temperatures above 32°C will also inhibit root development.

4. Appropriate fertilization

If the soil does not contain sufficient nutrients, the cucumber seedlings will not be able to grow thick. Timely fertilization and nutritional supplementation are required. You can use nitrogen, phosphorus and potassium compound fertilizer and water it on the roots. Or use potassium dihydrogen phosphate as foliar fertilizer and spray it on the leaves of the plant. Do this every 7-10 days, two to three times, and the condition will improve.
