Chemical-Free Weed Control of Asparagus Bed
I have a 8, 45' rows of asparagus I planted this Spring. I hoed the beds a couple of times earlier in the year and pulled large tap roots weeds such as pigweed, sticker bush, etc...The ferns have done well but so has the grass between the rows. My plan to tackle this grass is to wait until the ferns brown, mow everything, cover the area with plastic for a few weeks, layer with compost, and finally layer with straw. My question is will the heat from the plastic heat the ground enough to pose a threat to my asparagus crowns below the ground?
