Planting the seedlings you’ve raised carefully indoors is a proud moment. But be sure to acclimatize them to their new outdoor home first, or you’ll risk losing your plants and wasting all that hard work. This is a process known to gardeners as hardening off plants.
In spring, we plant several crops into hay mulch to help control weeds, including reducing the "weed seed bank". Few weeds other than perennial grasses will come up through a 4-inch layer of hay. Mulches of natural materials keep the soil damper, which can mean higher yields and less need to water. This method is quick and easy, and more effective than mulching around the plants after transplanting.
