Moving companies typically don't take plants. Give them away or arrange special transportation. Plan your meals to use up food from your freezer and pantry. Don't forget brokerage accounts. Verify the moving estimate.
Movers refuse combustibles.
Dispose of any you have and drain gasoline-powered tools of fuel and oil. Pack a separate bag with things you will need while your household goods are in transit. Carefully inventory and inspect your furniture, and go through it with the mover. Unless specifically excluded by a contract of sale, window coverings stay with the house. Arrange to have the phone disconnected the day after you leave.
