acid-loving

If you are growing acid-loving plants like blueberries, heathers, hollies and rhododendrons, they will not appreciate the addition of wood ash.

A: The answer is yes, especially for acid-loving plants like the ones you mentioned.

Also do not apply wood ash to acid-loving plants such as blueberries, rhododendrons and azaleas.

The surface roots should be lightly mulched in the spring and fed with a fertilizer formulated for acid-loving shrubs.

Some SoCal gardeners add about 50% sphagnum peat moss to their soil when planting acid-loving plants like blueberries and azaleas, because it helps lower the acidity.
