When lifting a wall section into position, the bottom of the wall can slip across the floor deck, and even fall off. If you are short on help, a solution is to position the section as it lays flat, then drive duplex nails (with two heads) through the bottom plate into the floor. The nails will bend as you raise the wall to a vertical position. After securing, pull out the duplex nails.
If you don’t have a soil moisture probe, some simple guidelines can help you decide when to water. Water when grass changes from a green to a grayish blue color, when grass leaves begin to roll, when the grass stays down after being walked on, or when you can’t easily push a screwdriver down into the soil a half foot or so. Apply 1/4 in. of water and then check to see if the soil is wet down to 6 in. If it isn’t, make another application just so the soil is moist, but not wet or sticky.
