Take up good, sound, young and well established runners; remove all decayed leaves, tie them in bunches of twenty-five or fifty, with their crowns evenly arranged; wrap in moist, swamp moss; pack tight in an open box, with the crowns upward, and nail slats across the top to keep them in, and yet allow free access of air. Thus shipped, they will go long distances without injury. The best season for shipping in spring, is the last of April, and in fall, middle of September. Nurserymen sometimes take up large quantities and heel them in during the winter, and thus are able to ship very early the next season to Southern localities, or more distant points. In New Jersey it is a common practice to pack in barrels with the tops out, slats out open for ventilation, and the roots turned toward the centre, and the vacant space filled in with wet sand. If the weather is cool they will go reasonable distances without any injury, although we are of the belief that in warm weather such a practice would be unsafe, and might cause fermentation. Plants should never be packed loosely, nor shipped in an unarranged mass.
It is better to charge a little higher price and do the plants up more neatly.
