Green onion, also known as scallion, is a popular ingredient in many recipes around the world. It is easy to grow and can be harvested throughout the year. However, green onions are susceptible to rotting, which can be caused by various factors such as overwatering, poor drainage, fungal infection, and more. In this article, we will discuss how to prevent green onion plants from rotting and ensure that they stay healthy and fresh.
1. Choose the right soil
The first step to preventing green onion plants from rotting is selecting the right soil. The ideal soil for growing green onions should be well-draining and loose. It should also have good water retention capacity to ensure that the plant gets enough water without getting waterlogged.
To prepare the soil, mix compost or organic matter with the soil to improve its quality. This will help to maintain good soil structure and allow air circulation around the roots.
2. Watering
Watering is crucial for green onion plants but it can also be the cause of their rotting if not done properly. Overwatering can lead to waterlogging and root rot, which can kill the plant. To prevent this, water the plant only when the top layer of soil feels dry to the touch.
It is also important to ensure that there is proper drainage in the pot or garden bed where you are growing your green onions. This will prevent water from accumulating around the roots and causing rot.
3. Fertilization
Green onion plants require proper nutrition to grow healthy and strong. However, over-fertilization can cause root burn and damage the plant’s health. To avoid this, use a balanced fertilizer with an NPK ratio of 10-10-10 or lower.
Apply the fertilizer once every two weeks during the growing season, and make sure to follow the instructions on the label.
4. Pest and Disease Control
Green onions can be susceptible to various pests and diseases, which can cause rotting. Some common diseases that affect green onion plants include onion smut, leaf blight, and downy mildew.
To prevent these diseases, keep the plants well-ventilated and avoid overcrowding. Also, remove any infected plants or leaves as soon as you notice them.
5. Harvesting
Harvesting is an important step in preventing green onion plants from rotting. Cut the green onions at the base of the stem when they are fully grown, but before they start to flower. Leaving them in the ground for too long can cause them to rot and attract pests.
