Horticulture Advisory: Protecting Fruit Plants from Adverse Winter Conditions
The recent spell of biting cold and dense fog in Mandi district is taking a toll on fruit plants, posing a risk of economic loss for local gardeners. Deputy Director of Horticulture, Mandi, shared these concerns on Tuesday, emphasizing the need for preventive measures to minimize damage during this harsh winter season.
Extreme cold and persistent fog can cause plant cells to burst, leading to damage. This can result in poor fruit production, premature flower drop, and decay of existing fruits. Furthermore, prolonged foggy conditions stunt plant growth and reduce flower and fruit yields in the following season.
Tips to Protect Fruit Plants
Deputy Director Sanjay Gupta highlighted the drought-like conditions in the district, exacerbated by the lack of rainfall. He recommended the following measures to safeguard fruit plants from cold and fog damage:
1. Choose Resistant Varieties: Opt for fruit plant varieties with a natural resistance to fog.
2. Cover Young Plants: Use sarkanda grass, dry corn stalks, or gunny sacks to cover small plants. Keep the southeast side open to allow sunlight and airflow.
3. Spray and Irrigate: Light irrigation and spraying water during foggy periods can raise the garden temperature by 1–2 degrees Celsius.
4. Burn Residues for Warmth: Burn dry leaves, grass, or plant residues in the evening to increase warmth in the orchard.
5. Use Shade Nets: Protect plantations with nylon shade nets (50% shade) to mitigate fog effects.
6. Apply Potash Fertilizer: Providing an approved amount of potash enhances the plants’ tolerance to fog.
7. Coat Tree Stems: Apply a mixture of Bordeaux paste (1 kg copper sulfate, 1 kg lime, 1–3 liters linseed oil) or copper oxychloride on tree stems up to 2.5 feet above the ground.
Guidance for Gardeners
Effective management can significantly reduce the damage caused by winter fog, ensuring healthier plants and better yields. Farmers and gardeners facing issues with their fruit plants are encouraged to consult their nearest Horticulture Department office for personalized solutions.
By adopting these protective measures, gardeners can safeguard their orchards and reduce potential losses during the challenging winter months.
