Transplant garden plants on a shady day, in late afternoon or
in early evening to prevent wilting, say horticulturists with the University of
Georgia Extension Service. It helps to water the plants several hours before
transplanting. When using bare-root plants, such as sweet potato slips or plants
from an old-time farm-supply store, soak the roots for an hour or two before
setting them out in the garden. Don't allow them to dry out completely at any
time. Handle the plants carefully. Don't disturb the roots or bruise the stems.
