Horticulture

Place potted plant in box.  Surround pot with thickly crushed newspaper to stabilize.  Blow up commercial plastic sandwich bags - twist end, fold over, and tie very tightly to  prevent escape of air.  Place inflated bags under and around foliage (these are so light they will protect the plant and not interfere with its natural shape.
 

Transport plant in plastic foam (picnic) container.  Use plastic pellets to protect plant.
 

Cart horticulture in beer or wine cartons already fitted with dividers.
 

Support plants in plastic foam chemical boxes (with four openings) or cardboard boxes with circular holds cut to size of pot.  Weight the bottom of the box with bricks (or something similar) to prevent tipping.
 

Drill a board full of holes for dowels that can be placed around pots of varying sizes.  Surround pot with dowels to brace it.  Handles may be added to the board.
 

Tote small pots in cases designed to hold jelly glasses.
 

Make sandbags of various sizes and partially fill to provide suitable strong support for different sized pots.
 

Shred newspaper and pack around plant to protect leaves.
 

Try using fat twisted beach and bath towels.
