I'm putting in three hugelkultur beds this year, and one is already complete. I just got back my soil test results, and my soil has a PH of 5.3 which is to low for the plants i want to grow. Does anyone know if its worth adding some lime? I assume over the years the decaying wood will raise the PH of the soil.
Few ordinary vegetables will want a pH that low. Blueberries and strawberries might. So yeah, lime or wood ash would be a good thing, at least on the outer layers where most of the feeder roots are. You're right that as the woody stuff decays it will pull the pH toward neutral, but that might take a few years....
