Which Fertilizers Are Effective to Apply Under the Snow in Winter: Tips for Increasing Yields

During the winter period, when garden plots are covered with snow, certain types of fertilizers remain effective for nourishing the soil. Thawing water helps nutrients penetrate deeper layers, aiding the soil in recovering and accumulating resources for the new season. Winter fertilization positively impacts plant health, providing them with a strong start in spring and increasing potential yields.

Advantages of Winter Soil Fertilization

Throughout the season, the soil becomes depleted and loses a significant portion of beneficial substances. Applying fertilizers in winter has several advantages: the nourishment occurs gradually, and thawing water evenly distributes the nutrient components in the soil. This method is especially recommended for fruit trees, berry crops, and perennials that require additional support after autumn fruiting.

Fertilizers Recommended for Application Under the Snow

• Wood Ash. A natural fertilizer that helps strengthen the root system, boosts plant immunity, and reduces the risk of fungal diseases. Suitable for nourishing onions, garlic, berry bushes, and trees. It adds lightness to the soil and improves its structure. Recommended rate: 1 cup per 1 m².
• Superphosphate. In winter, this fertilizer transforms into a form that is easily accessible to plants in spring. It promotes the development of a strong root system and the formation of flower buds. Particularly beneficial for raspberries, currants, strawberries, and grapes. Application rate: 30-40 g per 1 m².
• Potassium Fertilizers. Potassium sulfate helps plants survive frosts and increases their resistance to diseases and weather stresses. The fertilizer can be spread directly on the snow — thawing water will distribute it in the soil. Recommended dosage: 15-25 g per 1 m².
• Organic Fertilizers. Organic fertilizers include compost, manure, and bone meal. They are applied in a layer of 2-3 cm. Over the winter, the organic matter partially penetrates the soil, enriching it with humus. Bone meal is a long-lasting source of phosphorus. Dosage: 100-200 g per 1 m².
