I had another deep watering spike that got clogged and just never really worked that well. I used this one last summer to try to save our huge pecan trees from the intense heat wave, and it worked great! Our pecan trees are still alive and many of our neighbors lost theirs. I moved it around our trees in a spiral pattern. I moved it once in the morning and once in the evening, and it seemed to work like a charm. After an entire summer of use, it still looks almost new.
