Attack weeds as early as possible. They are called weeds in part because they are first up and outcompete other plants for space and light and water. Most of us don’t think about this need in early spring, as we have other things on our minds. But get them early. Good news is they are fairly easy to pull at this stage.
Delay mulching for a few weeks. Let the soil warm up and let water get to your new growth. Wait until plants are a bit established and you can see better where to mulch.
