I've had similar experiences with straw—definitely helps retain moisture, but the sprouting can be a nuisance. One trick I've found helpful is using aged or partially decomposed straw; fewer viable seeds to deal with that way. Might be worth trying next time around.
That's a good tip about using partially decomposed straw; I hadn't thought of that before. I've usually opted for mulch or wood chips to avoid sprouting altogether. Have you noticed any difference in moisture retention between straw and wood-based mulches?
"Have you noticed any difference in moisture retention between straw and wood-based mulches?"
I've experimented with both straw and wood chips extensively, and from my experience, partially decomposed straw tends to retain moisture slightly better initially due to its finer texture and denser layering. Wood chips, however, offer more consistent moisture retention over a longer period as they break down slowly. Your approach of using mulch or wood chips to avoid sprouting is definitely sound—it's always good practice to minimize unwanted growth right from the start.
I've found straw does hold moisture pretty well at first, but honestly, it breaks down quicker than I'd like. Wood chips seem to last longer and keep things consistently damp underneath. Plus, straw can sometimes attract rodents—had that issue once, wasn't fun. Wood chips have been my go-to lately, especially since I can usually get them cheap or even free from local tree services.
Totally agree about the wood chips. Straw seems great at first glance, but yeah, rodents can be a real headache—I had mice nesting in mine one winter, not something I'd recommend dealing with again. Wood chips have been solid for me too, especially cedar if you can find it. It naturally repels pests and smells pretty nice too. Plus, like you said, tree services usually have plenty they're happy to unload for free or cheap... win-win situation all around.
