Hi there! I recently started my food forest by planting two apples, two pears, a fig, a mulberry, two aronia and two goumi bushes! Very exciting to have them in the ground after the many months of researching and waiting. In my research I found these two watering systems but haven't bought anything yet, and can't find any info by searching. Also found a little info about people doing this with PVC pipes with holes in them. Anyone have experience with any of these or thoughts about them? Is it really beneficial to the tree? Is the spike on the bucket that much better than just a bucket with holes in in? How do you water your trees? Anything I should know as a brand new tree owner? They are mulched well!
Both look cool, and both can be make from home for cheaper, if you've a mind for it.
However, in your climate, if you've molded the earth around your tree to collect rainwater, you may not have a need to irrigate at all after a few years, so I'd pick the bucket method, as it's more removable. You can also move the bucket to different spots under the tree whenever refilling, allowing the root directionality issue to be minimized.
