What is a consequence of overwatering plants in a greenhouse?

Overwatering plants in a greenhouse can lead to increased cell elongation, resulting in leggy growth. This occurs because excess water in the soil can lead to a condition known as waterlogging, which reduces the amount of oxygen available to plant roots. When roots do not get enough oxygen, this can inhibit their ability to take up water and nutrients effectively. Consequently, the plant experiences stress, and as a response, it stretches or elongates in an attempt to reach for more light, producing long, weak stems that are characteristic of leggy growth.

Plants that are overwatered often exhibit other signs of stress and health issues, such as yellowing leaves or poor overall vigor, but the specific consequence of leggy growth highlights how crucial proper watering practices are for plant health in a greenhouse environment. This understanding underscores the importance of maintaining a balanced watering routine to encourage robust, healthy growth.
