Ample soil moisture must be maintained throughout the two-year maintenance period. Need for watering can be determined by feeling the soil under the mulch at 3 - 6" depth for moisture. (Check twice per week for adequate soil moisture).
Follow the 3-2-1 method: start by watering 3 times per week for the first month, 2 times per week for the second month and 1 time per week for the third month. Then water 2 times per month for the next 3 months and 1 time per month through the next growing season (March - August).
Mulch
Mulch must be renewed once a year at 2" depth and at a radius of 24 - 36" from, but not touching, the trunk of each tree for the two-year maintenance period. Proper mulching helps retain water, moderates soil temperature, and can reduce the need for weed control .
Inexpensive mulch is available from the City's brush site, located at 1800 Old Bitters Road. For more information, dial 311.
Tree Wells
Tree wells must be kept free of weeds for the two-year maintenance period. This weed-free zone can be accomplished by pulling weeds on a monthly basis.
Do not use string trimmers within the mulched area around a tree. String trimmers will damage and may kill the tree.
