Wood ashes have long been used to neutralize excess soil acidity and as a fertilizer for certain types of trees, shrubs and other plants that prefer alkaline soils. According to the University of California at Davis website, wood ashes contain up to half their weight in alkaline calcium and magnesium carbonates. Wood ashes also supply potassium, phosphorous and a number of minor trace minerals from the original wood; they do not contain nitrogen.
Trees
Trees that do well in alkaline soil fertilized with wood ashes, says the University of Minnesota Extension Service website, include silver maple (Acer saccarinum), buckeye (Aesculus glabra), hackberry (Celtis occidentalis), green ash (Fraxinus pennsylvanica), honey locust (Gleditsia triacanthos), ironwood (Ostrya virginiana), chokecherry (Prunus virginiana) and Austrian pine (Pinus nigra).
Shrubs
Shrubs that like alkaline soils, says the University of Minnesota Extension website, include Chinese juniper (Juniperus chinensis), bush cinquefoil (Potentilla fruticosa), viburnum (Viburnum spp.), lilac (Syringa vulgaris), hydrangea (Hydrangea paniculata) and berberry (Berberis thunbergii).
Flowers
Flowering plants that thrive in alkaline soil, says the University of Minnesota, include daylilies (Hemerocallus spp.), coneflower (Echinacea purpura), hostas (Hosta spp.), garden phlox (Phlox paniculata), creeping phlox (Phlox subulata), salvia (Salvia nemorosa), sweet William (Dianthus barbatus), clematis (Clematis spp.), honeysuckle (Lonicera spp.) and coral bells (Heuchera sanguinea).
Vegetables & Herbs
Wood ashes are good for certain alkaline-favoring vegetables and herbs, says the University of Minnesota, including beans, peas, peppers, spinach, parsley, thyme, borage, chamomile and wormwood.
