An unprepared gardener is perplexed when he sees the leaves of cucumber seedlings turning yellow.
This is often due to mistakes that many novice gardeners make. If you don't delay solving the problem, you can save the seedlings and get a decent harvest.
Lack of light
Impatient gardeners sometimes sow cucumbers for seedlings too early. The daylight hours are short, so the plants do not receive enough light. It is necessary to move the seedlings to a southern window and additionally use a phytolamp.
Dehydration
Yellowing of leaves may be due to lack of water. Sometimes gardeners water plants rarely, but abundantly, or often, but little. Any of these options leads to yellowing of foliage and even death of seedlings.
Temperature
Some gardeners believe that hardening off seedlings is beneficial. This is true, but you need to know when to stop.
As for cucumbers, the soil temperature should be no less than +17 °C. A cool balcony and drafts can easily cause yellowing of the leaves.
