Gerhard,

That sounds fine, but I have a couple questions. First of all, what is the pH of the surrounding soil and do you have lots of earthworms around? The reason I ask is that if the surrounding soil is neutral or alkaline, the bed you are constructing could raise in pH very easily over time. Earthworms tend to bring surrounding soil into the bed which too can increase the pH.

I would suggest you mound the bed, such that the plants are actually growing above the normal soil line. That will keep the surrounding soil from washing into the bed. Also, if your native soil is neutral or basic I would water frequently with acidified rainwater using vinegar as the acid. Avoid tap or well water. If the surrounding soil is acidic (below pH 5) you may not have to do this, but it won't hurt the plants either.

Let us know how they do.


Tom
