If you have several blueberry bushes and you want tasty and he althy fruit, you can use a solution of stale bread and water as an acidifying fertilizer.
If you are looking for ecological and proven methods of treating diseases, pests and plant slurries, we recommend:
Put approx. 1.5 kg of old crushed bread into a plastic bucket with a capacity of 10 liters. Pour water to the top and set aside for a few days in a warm place. We mix it up from time to time.
Use the fermented mixture to water the soil under the blueberries - 2 liters of fertilizer for each bush. We repeat the activity several times during the season.
