Mulching..... Water concern?
I'm considering mulching my vegetable gardens. I've read and read about the benefits of mulching in the vege garden. Cooler soil temps, weed control, less watering, etc. I'm a big fan of all those.
My dilemma is this...... To prevent weeds effectively, mulch depth should be 3". 2" absolute minimum. I'm considering an untreated western red cedar. I like the look, the way it interlocks and resists wind and slowly adds to the soil be decomposing. It's easy to move for future planting and is durable.
My concern is this... Doesn't a layer of mulch that thick absorb water meaning my overhead irrigation system would have to run longer to penetrate the soil sufficiently?
Your thoughts are greatly appreciated!
