Hugelkultur

I am trying to figure out what is going on in my big raised bed hugelkultur. I'm in an arid desert and temps recently spiked. Because I was still trying too establish the asparagus crowns and strawberries in that bed, I'd been watering deeply a couple of times a week. I don't know if it's because of the heat and wind or maybe I was overwatering, but a couple highbush blueberries that had been doing well for months suddenly look as though their leaves are drying up and falling off. Any ideas why that might be? They're a highbush variety that is supposed to do well in our zone.

Would it be possible to post a picture?

A little more info would be good on this one!!! Stuff like where the different plants are located on the mound in relation to each other, orientation of the mound and plantings, actual location-ish information, etc. There could be a number of things going on there, but without a little more info I don't think you're going to get a whole lot of useful help.

My best guess based on the limited info provided would be to look at a possible over watering situation as the cause of the problem. Adding the extra water for the other plants might have water logged the berries and/or leached away the nutrient...maybe???
