Cut grass is working well for us here. We also have straw as a mulch that is working well too. I cannot wait until Fall when I get to mulch with dried leaves. I have mulched like crazy and it is working. The only plants not mulched are lettuce, carrots and radishes. I made the mistake of mulching over the parsnips and they didn't come up well. I think the straw mulch was too much for them to push through. I well not make that mistake next year.Today I watered all the veggies (butternut squash, tomatoes, peppers, rhubarb, asparagus, cabbage) and worked on finishing mulching. I'm trying to get the entire veggie patch mulched with cut grass so we have to weed as little as possible.
