LANDSCAPE PLANTING SPECIES SURVIVAL

THIRTY-SIX PLANTING CONTRACTS, INSTALLED IN THE FIVE YEAR PERIOD BETWEEN 1963 AND 1967 AND LOCATED THROUGHOUT MINNESOTA ON INTERSTATE, STATE PRIMARY, AND COUNTY ROADS, ARE EVALUATED. FACTORS THAT AFFECT SURVIVAL INCLUDE: SOILS, PLANT HARDINESS, PLANTING DESIGN, GEOGRAPHIC LOCATION, DRAINAGE, CONTRACT REQUIREMENTS AND ADMINISTRATION, SLOPE EXPOSURE, COMPETITION FROM OTHER VEGETATION, AND MAINTENANCE. FACTS AND FINDINGS RESULTING FROM THIS RESEARCH STUDY WILL BE IMPLEMENTED BY THE HIGHWAY DEPARTMENT AND OTHER AGENCIES IN IMPROVING FUTURE LANDSCAPE PLANTING WORK. IT WAS DETERMINED THAT THE SURVIVAL AND VIGOROUS GROWTH OF PLANT MATERIALS WERE THE RESULT OF A COMBINATION OF FACTORS, BUT THE MOST IMPORTANT FACTOR WAS DIRECTLY RELATED TO THE TIMING AND AMOUNT OF WATER APPLIED DURING AND FOLLOWING THE PLANTING OPERATION. WITHOUT SUFFICIENT MOISTURE DURING THE FIRST GROWING SEASON, MANY PLANTS FAILED TO BECOME ESTABLISHED. THEY EITHER DIED OR BECOME STUNTED AND DIED IN THE FOLLOWING YEARS. /FHWA/
