In yesterday's monthly community Q&A meet-up (Prairie Upping) I went over a few more details about this 12,000 plug project: how I designed, selected plants, installed, etc. (You can watch the recording, and every recording from this year, by signing up.)
Often the topic of mulching comes up so I'm glad to address a few of the most common questions:
1) How much mulch? On our clay to clay loam soils we use 1 to 1.5" in shade, and 1.5 to 2" in such. Mulch breaks down faster in sun. The goal is just to slow up annual weeds for DIY managing clients then have it break down soon enough to allow plants to self sow. In sand I would never use wood mulch.
2) Mulch before or after planting? Always before. It's really hard to carefully mulch around hundreds and thousands of tiny plugs post install.
3) Preen or not? On some jobs I come back and wish we had used it, but I generally don't. Annual weeds won't be back the next year if we planted thickly enough, although if something like crabgrass gets too thick it's best to cut it back a bit to let light back on the plugs. Annuals are nature's way to heal over a wound and, in some cases, can even be helpful / useful in controlling more problematic / invasive plants.
