14. The plants are best left in the open coldframe all winter, mulched with 
leaves, preferably oak leaves, and in the early spring, before the buds have 
begun to push, they should be very carefully lifted and moved, with the whole 
root mat and adhering soil intact, to a peat and sand nursery bed at a spacing 
of about a foot each way. 
ROOT CUTTINGS. 
The early experiments with root cuttings gave such a small per- 
centage of rooted plants that further experiments in the greenhouse 
were abandoned. At Whitesbog, N. J., however, in order that the 
roots as well as the tops of selected wild plants might be utilized, 
cuttings of the roots were made about 3 to 4 inches long and of all 
sizes down to a little less than an" eighth of an inch in diameter. 
These were given the same treatment as tubered cuttings in cold- 
frames. A high percentage of rooted plants resulted. (See PL XI.) 
This may prove to be one of the most satisfactory methods of propa- 
gating plants that have large root systems. 
TREATMENT OF YOUNG PLANTS. 
When blueberry plants, either large or small, are grown in porous 
pots, the surface of the pot should never be allowed to become dry, 
for the rootlets which grow through the soil to the wall of the pot 
for air are extremely fine and easily killed by drying, to the great 
injury of the plant. This danger may be eliminated by bedding the 
pots to the rim in a well-drained bed of sand or by setting the pot 
in another pot of 2 to 4 inches greater diameter, with a packing of 
moist sphagnum moss between and broken crocks at the bottom. (See 
PI. XII, fig. 1.) 
A burning of the young leaves and growing tips of twigs is often 
produced by the hot sun from the middle of June to the middle of 
September. Plants in pots or nursery beds are easily protected from 
such injury and forced to their maximum growth by a half-shade 
covering of slats, the slats and the spaces between being of the same 
width. On cloudy days the shade should be removed. It should not 
be used in the fall or spring. 
During the winter the rooted cuttings, or 1-year-old plants, should 
be kept outdoors, exposed to freezing temperatures, their soil 
mulched with leaves, preferably oak leaves. When kept in a warm 
greenhouse during the winter they make no growth before spring. 
Even then their growth is abnormal, often feeble, or sometimes 
deferred for a whole year. 
FIELD PLANTING. 
Plants from cuttings or rooted shoots are ready for permanent 
field planting when they are 1 or 2 years old and 6 to 18 inches 
high. (See PI. XII, fig. 2.) 
It is a curious fact that these plants send out no new roots in 
spring until they are in full leaf, when their flowering is nearly or
