How much mulch?
I put down some additional mulch a few days ago. I probably have two or three inches of it on my azaleas. It rained yesterday - .33 inch. I checked the mulch and it was wet but the soil beneath it was dry. We got another little burst of rain this afternoon - I checked the mulch and soil and the mulch was wet but soil was dry.
I understand the value of mulch in terms of preventing evaporation but it also stops small rains from getting through to the soil much less to the roots.
How much mulch should I have?
