Many speak of the benefits of ash in gardening, but sometimes this source of potassium and phosphorus can lead to undesirable consequences.
The mistake is most often made by novice gardeners, but sometimes even experienced gardeners make it.
Not All Ash is Suitable
You should not use ash left over from burning fences or trash. Ash from a barbecue is also often unsuitable, as special substances may be used for ignition that negatively affect plants.
Ash obtained from a stove or after burning branches and logs is suitable.
Smoldering Flame
Ash cannot be used everywhere. Sometimes plants require acidic soil, and ash acts as a liming agent, which can lead to poor seedling growth. It is recommended to check the soil acidity with water and vinegar before applying ash.
Dosage
You should not sprinkle ash in unlimited quantities. The dosage must be observed; otherwise, there may be an imbalance of trace elements. For example, plants may receive too much phosphorus and potassium, while nitrogen may be insufficient, negatively affecting the quantity and quality of the harvest.
