Second photo looks best . I like to spread out the stakes in each bucket . We cut buckets in half and makes them easier to spread . A half bucket is plenty of concrete for 8 to 10 good stakes . We just put dry quickcrete in the bucket and add water, then add stakes. No need to go to the trouble of premixing concrete . We place 6 to 12 to a spot . They are great and hardwood stakes last for years submerged . Also use a PVC stake driver to put in without concrete or buckets . Check out this on youtube .
