I am planning to mulch my tomatoes with barley straw, I have a whole bale, (we use it in the pond to keep string algae at bay), I am wondering if it will have any effect on the tomatoes? I have never used mulch on the tomatoes, and I figures that it would make gardening easier. Am I right?????????
Paul, mulching with straw does help prevent splashback infection from any spores and bacteria that were shed the previous year by infected plants.
But all NEW foliage infections are spread via wind and rain so mulching can do nothing to prevent those. One can prevent the fungal ones fairly easily with the best anti-fungal but what we have available to us to prevent the NEW bacterial ones are not all that effective.
