Creating a pond or natural bird bath in a hugelkultur bed.

Hello there! I wanna find out if we could add a pond or a small bath for birds in a wildlife hugelkultur garden. Any of you done it before? I wanna explore ways to improve wildlife habitat. Could we also create puddles on the mounds? Please share me something so this topic becomes more edifying. Take care.

I gave found hugels to be very well drained, so it would take a liner or container.

Capital Idea! I'll try it. We need something to keep the water running?
