Ash improves the structure of the soil, increases its fertility and promotes the development of beneficial microflora.

However, not all plants respond equally well to ash, and its improper use can cause harm.

Anastasia Kovrizhnykh , an expert of the online publication "BelNovosti", an agronomist and landscape designer, told how to use ash.

Plants that don't like ash

Ash has an alkalizing effect, so it is not recommended to use it for feeding plants that prefer acidic soils.

1. Rhododendrons and azaleas: These plants need acidic soil to thrive. Ash can increase the pH of the soil and cause chlorosis – yellowing of the leaves.

2. Hydrangeas: The color of hydrangea flowers depends on the acidity of the soil. Ash can make the soil alkaline and cause the flowers to change color.

3. Conifers: Most conifers also prefer acidic soils. Ash can disrupt the balance of nutrients and negatively affect their growth.

4. Plants of the heather family: heather, lingonberry, blueberry and other representatives of this family need acidic soil for normal development. Ash can lead to their death.

How to use ash correctly

1. Determine the acidity of the soil: Before using ash, it is necessary to determine the pH of the soil. If the soil is acidic, ash can be used in limited quantities, after mixing it with peat or compost.

2. Apply ash in the fall: Fall is the ideal time to apply ash to the soil. It will have time to decompose over the winter and enrich the soil with useful substances.

3. Do not use fresh ash: Fresh ash contains a large amount of alkaline compounds that can damage plant roots. Ash must be aged for several months before use.

To use or not to use

Ash is a valuable fertilizer that can be very beneficial to your plants if used correctly. However, it is important to consider the characteristics of each crop and not to use ash to feed plants that prefer acidic soil.
