Noticed a huge shift in my backyard after 3 years of mulching

I moved into a house in Austin back in 2020 with a barren dirt yard. Over the past 3 years I've been adding a 2 inch layer of wood mulch each spring. Now the soil is dark and spongy instead of hard clay. The earthworms showed up after about 18 months and this year I saw my first fireflies. I think the mulch traps moisture and breaks down into organic matter over time. Has anyone else seen a similar change with something as simple as mulch?

Three years is about right for the clay to start breaking down. I did the same thing on a rental property in San Antonio. The first year it just sat on top and looked like a mess. By year two the top inch started getting dark. Now the soil is loose enough that stuff actually drains instead of pooling. One thing to watch for is that wood mulch can tie up nitrogen as it decomposes. I throw a little organic fertilizer on before I spread the new layer each spring. Keeps the plants from going pale.

I started with about 3 inches of cedar mulch in the backyard of my Houston place back in 2018, and it took a full two years before I saw real worms moving in. The clay was so hard the first summer that water just sat on top for hours, but by year three it was draining like a normal lawn. Something I did that helped was mixing in some compost from the hardware store with the second layer of mulch. That seemed to speed up the breakdown a lot and kept my plants from going pale. It's crazy how a cheap pile of wood chips can turn rock hard dirt into something alive.
