. 5"0£ -3- Section 4. Trees other than palms may only be planted November through April. Balled and burlapped trees should be planted as soon as possible after diggingr but if trees must be storedr bury root balls in wood chips or similar material to prevent root systems from drying out. Section 5. Newly planted trees require special attention during the first three growing seasons. a) Ample soil moisture must be maintained throughout the first and second growing seasons. Supplement natural rainfall with 1 inch of water every 7 days May through September the first yearr and every 14 days May through September the second year. Watering can be skipped if natural rainfall totals 1 inch or more since the last scheduled watering. since overwatering can be detrimental to the tree's healthr the supervisor should examine the soil (feel the upper layer) for evidence of ample moisture. b) Mulching aides water retentionr moderates soil' temperature and provides a favorable Bnvironment for microorganisms. A layer of mulch 3 to 4 inches deep is required over the entire planting area at the time of planting. Mulch should be pulled away from direct contact with the trunk. Mulch may be either granules/chunks of barkr wood chips or composted leaves and must be renewed annually or more often as needed. c) Newly planted trees require a high phosphorous fertilizer (17-23-6, 4-12-4r or 5-10-5) for root and stem growth. Balanced'fertilizers may be substituted for the high phosphorous fertilizer in limestone soils. Established trees should have a balanced fertilizer applied at the beginning of the third year to stimulate foliage growth. d) Weed control should be done twice annually for the - first two yearsr April-May and July-August. Use a contact herbicide like Glyphosate (Roundup@) applied according to the label. Prior to sprayingr remove all ground level and other sprouts on the stem that might come in contact with the spray. Spray only the green foliage to be killed. Keep the spray away from the foliage of the tree and any other plants that are to remaln.
