Vegetable planting management guide in November

November is the transition period from late autumn to winter. The temperature gradually drops and the rainfall decreases. This month is crucial for vegetable planting and management. So what specific management work should be done? Let’s take a look at the vegetable planting management guide for November.

1. Harvesting and planting

Late October to early November is the best harvesting period for most autumn-planted vegetables, such as cabbage, radish, carrots , etc. They should be picked in time to avoid frost damage. For vegetable gardens that are idle after the harvest, you can consider planting some cold-resistant "winter vegetables" such as spinach, cabbage, mustard , etc.

2. Insulation measures

For vegetables that are not cold-resistant, insulation measures should be taken in time when the temperature drops in November. Greenhouses can be built in the north. The walls of the greenhouse must have good thermal insulation properties, and the general wall thickness is about 1-1.2 meters. In the south, you can use a small arch shed. The frame of the arch shed can be made of bamboo or metal and covered with plastic film.

3. Fertilizer and water management

In November, the temperature drops, the growth rate of vegetables slows down, and the demand for fertilizer and water decreases. Generally, watering can be done according to the type of vegetables and soil moisture. In places with heavy rain, attention should also be paid to drainage and waterlogging prevention. In addition, phosphorus and potassium fertilizers can be applied in appropriate amounts in combination with watering to promote the development of vegetable root systems and enhance cold resistance.

4. Environmental Control

(1) Temperature: Maintain the temperature within a range suitable for vegetable growth, 15°C-20°C during the day and not less than 5°C at night. Take heating measures if necessary.

(2) Humidity: Provide adequate ventilation and control humidity to avoid the occurrence of diseases.

(3) Light: Increase artificial lighting to ensure that plants receive sufficient light, especially in winter when sunlight is insufficient.

5. Pest and disease control

First, it is necessary to remove withered plant debris in a timely manner to reduce the source of pests and diseases. Secondly, it is necessary to use environmentally friendly biological agents or chemical pesticides in a timely manner to control possible pest and disease problems. The key pests and diseases that need special attention include downy mildew of cruciferous vegetables, lettuce, and spinach; wilt, downy mildew, and powdery mildew of greenhouse cucumbers; leaf mold and gray mold of tomatoes; aphids, diamondback moths, and American leafminers, etc.

The above is an introduction to the vegetable planting management guide for November. Specific adjustments can be made based on actual planting conditions. Through reasonable arrangements and careful care, we can ensure the healthy growth of vegetables and a bountiful harvest even in the cold winter.
