I hauled about 6 truck loads of tree mulch into our garden this spring. We put the mulch on the pathways and then around the plants. Worked well and kept the weeds down.
Chickens are providing fertilizer for us too.
We are trying to get the Back to Eden no till garden method going.
I want to try planting directly in straw or hay bales though. Looks cool.
