Wood ash is not just waste from the stove, but a real natural fertilizer , which was appreciated by our ancestors. Thanks to its rich mineral composition, it improves soil fertility, protects tubers from pests and promotes the formation of large potatoes. But the most important thing is to use it correctly.
What are the benefits of ash:
- Potassium – promotes the growth of large, dense tubers;
- Phosphorus – helps root faster;
- Calcium, magnesium, boron – strengthen the plant’s immunity;
- Alkaline reaction – reduces acidity, prevents the development of rot and scab.
Ash is a natural alternative to mineral fertilizers that does not harm the environment.
Methods of application:
1. In the planting hole:
Add 1–2 tablespoons of ash to each hole, preferably with compost or humus. Mix with the soil to avoid direct contact with the fresh tuber.
2. Tuber treatment:
Before planting, roll the potatoes in dry ash – this is a natural protection against diseases and pests.
3. In between rows:
Sprinkle ashes on the soil between rows or when hilling – this will help nourish the plants during active growth.
Important tips:
- Do not combine ash with nitrogen fertilizers – this reduces their effectiveness.
- Use only clean ash without any plastic, paint, trash or coal.
- Store the ash in a dry place – wet ash loses its properties.
- Ash repels the Colorado potato beetle and other pests.
- You can prepare a solution for spraying: 1 cup of ash per 10 liters of water + 1 tablespoon of soap. Insist for a day, strain and treat the plants.
