Figure this might be a how longs a piece of string question but how rotted or old does it need to be? Have 10 or so rhododendrons I want to put wood chip around. I have some year old stuff that never got turned or some 2 week old chippings
Fresh woodchip consumes some nitrogen as it begins to age. Unless you can guarantee a reliable source of dilute water soluble nitrogenous compounds, (yes urine is good), use the aged stuff.
