[net.garden] Lilac Fertilizer

tjo@gypsy.UUCP (05/16/85)

A question about lilacs and wood ashes:

Speaking of lilacs, I've heard that wood or charcoal ashes are
especially beneficial as lilac fertilizer.  Aside from the fact 
that potassium is generally good for flowering plants, is there
any particular reason to use ashes for lilacs?

Also, should ashes be just as beneficial to  other deciduous 
flowering shrubs like forsythia, quince, etc?
What about deciduous azaleas (Exburies)?

	Woodland shrubs like azaleas, camelias, rhododendrons
and other members of the camelia and laurel family like very
acid soil (like that created on the forest floor through all
the leaf mold). I can't imagine that ash would do them any good.

Lilacs like alkaline soil.  Ashes will make your soil more alkaline.

I recommend against using ashes for azaleas, because these like acid
soil.  The Sunset Western Garden Book says that quince may suffer from
chlorosis in alkaline soils.  I don't know what forsythia likes.

Ashes in the soil will make carrots taste sweeter.
