Days are those who have a fireplace will turn to warm up ... But then not clean it thoroughly before you pick up the ashes of the wood. The ash is a first class natural fertilizer for your plants.
The ash in the soil raises the ph to acidic soils (for this and should not be added to oxyfila plants such as berries, the rhododendrons, azaleas, hydrangeas are etc.) and adds potassium, calcium and trace elements.
The average content of ash in key nutrients are 0-1-3 (NPK).
What to Watch:
-It should be added to ash beds to be planted with potatoes because they favor the attack of plants by the bacterium Streptomyces scabies.
-Can be added to the compost bin especially if you throw large quantities of pine needles or other acidic materials, when it corrects the ph of the mix.
-When it comes to throwing around the base of the plant repels insects in soil and snails, provided you do not get wet.
-The addition of large amounts of ash can cause a large increase in ph (alkaline) and the concentration of salts in the soil with adverse consequences for plants.
-Use only the ash from the combustion of untreated wood.
-Do not drop ashes along with nitrogen fertilizer because nitrogen will be lost.
