Exhibit A - Scope of Work 2025 <br />Rev. 3/26/2025 Page 21 <br /> <br />6.04 Staking <br /> <br />Remove stakes as soon as they are no longer needed. Stakes and ties shall be inspected at <br />least twice per year to prevent girdling of trunks or branches, and to prevent rubbing that <br />causes bark wounds and cambium damage. Contractor shall train trees and shrubs off <br />stakes, and adjust stakes and ties as necessary. <br /> <br />6.05 Weed Control <br /> <br />Keep basins and areas between plants free of weeds and turf. Avoid frequent soil <br />cultivation that destroys shallow roots. Where there is not adequate plant material to <br />suppress weeds, mulch is preferred to either spray or mechanical removal of weeds. <br /> <br />6.06 Insect & Disease Control <br /> <br />Maintain a reasonable control with approved materials. Monitor trees for presence of <br />mistletoe. Remove immediately upon discovery. Consult with County Extension Agents <br />for recommended methods of control and prevention of resprouting. The Contractor shall <br />use a systemic fungicide that controls anthracnose and plant disease, and shall also a <br />systemic control fireblight where necessary. <br /> <br />6.07 Fertilization <br /> <br />Once, late in spring, fertilize recently established plants with a soluble nitrate fertilizer. <br />Avoid applying fertilizer to the root ball and base of main stem; rather, spread evenly <br />under plant to drip line. Rates will vary from about a cup of nitrate fertilizer, (depending <br />on nitrogen percentage) around a newly installed small plant to about one half (1/2) lb. of <br />actual nitrogen per inch of trunk diameter measured four feet from the ground for mature <br />trees. <br />Docusign Envelope ID: 13FE48C5-D5F5-4601-826E-B8F264A57D7BDocusign Envelope ID: 7C0E76E7-1031-45FB-8C1F-DF2FE0E6CF0B
