Is cardboard ash good for soil? Cardboard ash is good for soil. Cardboard is, basically, wood ash. Most of this will be vaporised away during burning, leaving very little in the remaining cardboard ash.

If you have a fireplace or woodstove, use wood ashes to improve garden soil! Wood ash is full of nutrients that plants need, such as potassium and phosphorus, so it’s great for using on the vegetable garden. Ash from hardwoods like oak and beech are best as they contain more nutrients than ashes of softwoods like pine.

Amending Soil and Boosting Your Lawn Wood ash can be used to boost the pH of your lawn’s soil quickly—faster than limestone, since the ash is more water soluble. Most lawn and garden soil does well at a pH level between 6.0 and 7.0. Higher than 7, and it’s considered alkaline.

Too much ash can increase the soil pH to levels that interfere with plant growth. Repeated, heavy applications to the same spot (as if you used one corner of the yard as an ash dump) can effectively sterilize soil and threaten surface water quality.

Do not spread ashes around acid-loving plants like blueberries, strawberries, azaleas, rhododendrons, camellias, holly, potatoes or parsley. Plants that thrive with a dressing of wood ash include garlic, chives, leeks, lettuces, asparagus and stone-fruit trees.

Ash from wood fires, such as bonfires or wood burning stoves, can be a useful additive to the compost heap or can be applied directly to fallow ground and dug in.

Wood ashes make a great addition to the compost heap, where they’ll aid fertility (most of the nutrients needed by plants are contained in them to some degree). If you have a lot, don’t add them all at once as they are alkaline and raising the pH too much will affect the bacteria and worms at work.
