Thorough watering is the way to go. Otherwise you'll end up watering everyday. Outside you won't have a problem with water because it dries easy outside in the sun. Don't cover your plant or it will rot and die. That only works if you want to plant early and it is still cold out. By making a little greenhouse with the earth it keeps your sprouts warm and wet...then you take the cover off when it gets bigger. I woudn't do this. I don't recomend it.Most likely you'll end up with a rotted rootsystem and a dead plant!
