Wood ash has a high alkaline content, which makes it great for neutralizing acidic soil. To determine if your soil could benefit from an application of wood ash, first purchase a pH test kit at any garden center and test a small sample of soil from your garden beds. Before you add any ash to your garden, make sure it is completely cool to the touch.

The trick, for those trying this at home, is to let the fizzy water go flat before pouring it on your plants.
