[medit-plants] Re: urbanite found on facebook

Jeanne -

One finds concern about alkalinity regularly in garden books.  My observation over the past several decades is that this is largely due to the choice of certain plants - rhododenrons, azaleas, gazanias - that LOVE acidic soils and are adverse to lime.  But there are many, many plants that are fine with lime, especially many from mediterranean climates.  The flora of the Mediterranean itself is largely native to limestone soils.  In fact, our California soils are often not alkaline enough for them.

One of the best lavender gardens I ever created was on top of soil embedded with lots of chunks of concrete (from a former foundation).   They grew and flowered better than any I'd ever seen!

It all comes does to plant choice.  Proper amendments can also help for those plants requiring acid soil.

I found this on facebook and thought it would be pertinent to the discussion here. A friend expressed concern about concrete leaching something into the soil to make it more alkaline. Is that a concern?
