Instead of throwing out leftover whey, consider using it as a fertilizer for your plants. This natural solution not only feeds your crops but also helps protect cucumbers and grape bushes from oidium and powdery mildew. However, it is important that the whey is unsalted for optimal results.

Where Can I Apply Whey?

Adjust Soil Acidity

If the soil has a low pH, it is considered acidic, making it difficult for plants to absorb nutrients. To ensure your plants thrive, soil acidity must be appropriate for each species. You can test the soil’s acidity level to determine the need for adjustment.

Whey has a pH range of 4.0 to 6.1, which can help neutralize alkaline soil and create an ideal environment for plants that prefer more acidic conditions.

Whey as a Fertilizer

Adding whey to your fertilizer mix helps balance the soil’s composition and provides essential nutrients. Serum is rich in potassium, calcium, phosphorus, nitrogen, and magnesium, with NPK proportions of 0.15-0.05-0.17. These nutrients help plants grow strong without the risk of salt buildup, which can hinder plant development. The low NPK content of whey makes it suitable for regular feeding.

Water your plants with a serum solution that soaks the soil three centimeters deep. For grapes and hydrangeas, you can spray the solution directly on the leaves.

To prepare the serum fertilizer, mix 1000 ml of whey with 10 liters of water. This amount will cover approximately 10 m². Water your plants with this solution every two weeks until they begin to flower.

Whey as a Remedy for Powdery Mildew

For powdery mildew prevention, dilute sweet whey with water in a 50:50 ratio. For sour whey, use a 30:70 dilution. Apply the solution once every 14 days to keep your plants protected.

Powdery Mildew on Grapes

Grapes are particularly susceptible to powdery mildew, so it’s essential to treat them regularly. Apply a 10% whey solution once every 7 days during the growing season. Keep an eye on the disease’s progression and control it promptly.

Whey as a Weed Killer

Whey can also help you combat weeds. Simply pour it directly on and around the weeds. After a few treatments, the weeds will die off, and you’ll be able to remove them from your garden.

With these tips, you can effectively use whey as a natural solution to enhance your garden’s health and yield. We wish you a bountiful harvest!
