PLANT SPECIES SURVIVAL ON LANDSCAPE PLANTING PROJECTS

THE DIFFERENT PLANT SPECIES OR VARIETIES USED AND THEIR SURVIVAL ON 36 CONTRACT PLANTING PROJECTS INSTALLED BY DIFFERENT CONTRACTORS THROUGHOUT THE STATE WERE EVALUATED, STARTING IN THE SPRING OF 1963 AND ENDING IN THE FALL OF 1967. SURVIVAL AND GROWTH OF PLANT MATERIALS ON PLANTING CONTRACTS IS DIRECTLY RELATED TO THE AMOUNT OF WATERING DURING AND FOLLOWING THE PLANTING OPERATION. THE USE OF WOOD CHIP MULCH, WHICH ELIMINATES WEED GROWTH AND RETAINS SOIL MOISTURE, IMPROVED GROWTH AND SURVIVAL. COOPERATION BETWEEN THE ENGINEER AND THE LANDSCAPE ARCHITECT IN DEVELOPMENT OF THE ROADSIDE IS IMPORTANT. PLANTS TO BE PLANTED MUST HAVE A WIDE TOLERANCE RANGE TO ENVIRONMENTAL FACTORS. IT IS RECOMMENDED THAT PLANTING BE LIMITED TO FEWER PLANTS; PREFERABLY BALLED AND BURLAPPED AND TO BE PLANTED ON MORE FLAT, FAVORABLE SITES. CONTRACT ADMINISTRATION BY STATE PERSONNEL IS OF PRIME IMPORTANCE. INSPECTION OF THE QUALITY AND CONDITION OF PLANT MATERIAL, PROPER PLANT INSTALLATION AND MAINTENANCE MUST BE UP TO THE STANDARDS REQUIRED IN THE SPECIFICATION. FUNDS SHOULD BE BUDGETED FOR LANDSCAPE MAINTENANCE IN EACH MAINTENANCE DISTRICT OF THE STATE. THE MAINTENANCE OF THE ROADSIDE IS JUST AS IMPORTANT AS THE ROADWAY. THE EFFECT OF DEICING COMPOUNDS WAS NOTICEABLE ON THE FOLIAGE OF EVERGREENS PLANTED IN THE METROPOLITAN AREA. THIS DAMAGE IS STARTING TO SHOW IN TWIG DIEBACK ON DECIDUOUS PLANTS. ADDITIONAL RESEARCH IS NEEDED TO DETERMINE WHICH PLANT SPECIES WILL TOLERATE THIS CONDITION. /AUTHOR/
