Nomenclature Plant names conform to the nomenclature generally accepted in the nursery trade. The following texts are used as reference: Dirr, Michael A. 1998. Manual Of Woody Landscape Plants, 5th Edition, Stipes. Champaign, IL.; Bailey Hortorium. 1976. Hortus III. Macmillan Co. New York, NY. 2. Plant Measurements Sizing and grading standards shall conform to those published in the current edition of AMERICAN STANDARD FOR NURSERY STOCK, by The American Association of Nurserymen, Inc., 1250 I Street NW, Suite 500, Washington, DC 20005. All plants shall be in the upper half of the specified plant size range. 3. Quality All plant materials shall be ‘nursery grown’ in accordance with approved horticultural practices under climatic conditions similar to those in (list your town here). They shall have a habit of growth typical of the species or variety, grown from a single crown of roots and having been root pruned within the last two years. All plant materials must be exceptionally heavy, symmetrical, well branched and proportioned, and densely foliated when in leaf. All trees shall have their main leaders intact and, unless otherwise noted, have single straight trunks free of major branches up to a height of at least six (6) feet. Evergreens and clump form trees shall have dense, compact growth branched to the ground unless otherwise specified. Plants shall be matched when uniformity is required. 4. Substitutions Acceptance of this contract assumes the Contractor is able to supply all plant materials as specified and as indicated in the Plant List. Substitutions will not be permitted unless the specified materials are proven to be unobtainable or cannot meet specification requirements. If substitutions are necessary the use of the next larger size or nearest variety will be considered; such substitutions shall not increase the cost. Proposed substitutions must receive (your title) written authorization. When sources are located by (your title), there will be no substitutions. Nursery Practices and Specifications Edmund R. Gregan II Page 1 5. Inspections Plants shall be inspected, selected and tagged at the place of growth by (your title) with the Contractor. The Contractor shall make all necessary arrangements and will pay for all inspection costs. Notices requesting inspections must be received by (your title) at least five (5) days prior to anticipated inspection dates and within thirty (30) days following acceptance of the bid. Inspection and approval at the source will not waive the right of rejection for failure to meet other requirements. 6. Preparation and Shipment of Plant Materials The Contractor shall obtain and pay for all inspection certificates required and shall file copies with the (your title) before planting. All plants shall be prepared and packed, and protected to insure arrival at the site in good condition. They shall arrive fresh and properly dug, in sound, healthy, vigorous condition, with healthy well-developed tops and root systems. They shall be free of defects, eggs, larvae, insects, disease, injuries and physical damage, with all parts moist and showing active green cambium when cut. No plant branches shall be pruned prior to delivery. Deliveries shall correspond to planting schedules to insure immediate planting. Protection and handling of plants must be by approved horticultural methods to insure total recovery and healthy development. All plants shall be balled and burlapped (B&B), unless noted, and shall be moved as solid units having firm natural balls of soil of sufficient size to encompass the fibrous and feeding root system to insure full and prompt plant recovery. Plants with loose, manufactured, cracked, broken or undersized balls will be rejected. 7. Planting Seasons Planting shall progress only under favorable weather conditions within the following dates and will not be permitted when the ground is frozen or excessively moist. The Contractor may submit a written request stating conditions for a variance only if special conditions exist. Permission will be given if, in the opinion of the (your title), the variance is warranted.
