If you happen to lose most of the dirt around the roots, place the roots in moistened burlap or in plastic bags, and pack wet leaves around the roots. Roots can be kept moist with a spray bottle, if necessary. This is a wooden frame about one foot deep and usually four feet wide by 8-10 feet long. If possible, pot the plants before placing them in the bed, as this will lessen the number of times the roots have to be pulled up and traumatized. Then place the plants in the bed on the saturated layer, surround and cover the pots with soil or mulch, and spray the mulch with water.
Plants stored in a capillary bed can survive for up to a year with very little maintenance.
