Ashes can be extremely useful in your garden and for your plants since it becomes exceptional fertilizer.

Be it from the chimney in winter when logs heat your home, in fall after having burned leaves and old wood or in spring after your annual “spring cleaning” ashes are not to go about unused!

How ashes support plants

Ash has elevated potassium (K) and phosphorus (P) levels.

Its content isn’t as high as conventional fertilizer, but these nutrients still are resources that contribute to the plant’s development.

Regularly sifting ashes on flower beds or on the lawn can be considered to be excellent complementary fertilizer.

Can any type of ash be used?

No, it is important that this ash come from completely health wood:

  • no chemically treated wood
  • no wood with paint residues
  • no plastic

When should the ashes be sprinkled?

It is best to use the ashes in spring and in fall, because that is when the vegetation needs it most.

If you can’t store it, simply sprinkle them out right away, even in winter it will still find its way to support the plants.

It is better to proceed to sprinkling small amounts often rather than dumping a pile of ashes because if it rains, the pile will form a paste.

Using ashes in your compost

This isn’t really recommended because the ashes would tend to “suffocate” the compost.

Using ashes in your vegetable patch

If you have no idea where your wood came from, it is better not to use the ash.
Indeed, if ever poisonous toxic chemicals were in the wood, these would appear in the ashes and ultimately in the vegetables from the patch.

However, if the wood is untreated, this is perfectly possible and even recommended because it will increase the quality of your soil and the development of your plantations.

How about ashes as a slug repellent, does it work?

It is a fact that ash, just like flax mulch, sticks to the underside of slugs and thus slows them down.

For that, you must create small barriers 1 inch (2 to 3 cm) high around the most sensitive plants.
Take note that ashes have no impact whatsoever on slugs as soon as it rains.
