This is why they use peat moss in hanging baskets. The soil drys out so quickly in a hanging basket sI by adding peat moss water is retained much longer. Wood chips also absorb water but will release the water into the ground much faster than peat moss and won’t stay wet on the top surface.Only issue with peat moss is once it absorbs liquid, it seems to take forever and a day to dry out. I give it to my chickens for their dust bath but once it's pretty well used up I dump it in my garden, rather than leave it in the run.
