|Do pine needles make a good mulch for asparagus or any other vegetable for that matter?|
|Yes they do. They make an attractive mulch and don't tend to blow or float away. And they break down slowly over time. I have used them in my garden for years with great results.
You may need to apply them a little thicker than you would leaves for example, in order to block the sunlight enough to effectively prevent weed seed germination.
Thanks for the question!
