Cedars need lots of water.
It almost impossible to overwater a properly-planted cedar hedge. After initial planting your hedge should be watered every evening (unless it rains) for a period of 30 to 45 minutes for the first year. A soaker hose on a timer is highly recommended due to its equal and gentle watering methods. This will prevent unnecessary erosion of the freshly placed soil.
Cedar hedging should receive extra watering during dry summers and several heavy waterings until freeze up in the fall if the fall has been dry. The right amount of water is the amount that keeps the soil moist at all times to ensure the cedar trees do not get distressed. When watering in the summer heat it is best to water in the evening so as not to scorch the tree's foliage to keep the evaporation to a minimum. Watering in the fall before the ground freezes enables the roots to bulk up before going into winter, ensuring they will be strong and healthy entering spring.
Lack of a consistent source of water is the main reason for the decline of a healthy growing hedge.
Early spring, when things start to bloom, is the perfect time to fertilize your Eastern White cedar hedge.
For warranty purposes use bloodmeal, sheep manure and/or Miracle Gro for shrubs. This will provide the proper nutrients without burning the hedge (follow label directions closely). The only other time you need to fertilize is in the fall, again using the same fertilizers, to help provide the roots with nutrients to keep the trees healthy during the winter dormancy.
Do not trim your hedge for one full year.
This is for warranty reasons as well as the general health of your cedar hedge. Cedar trees have very shallow surface roots so the ground surface should not be cultivated. Weeds are best cut off rather than pulled. Mulch helps minimise weed growth. After one full year your cedars' roots will have "taken" and snipping the very top will encourage the trees to "bush out" while still achieving gains in height. You can trim them in the spring, summer or fall as long as they have taken root (one full year from date planted). Trimming the tops will make the sides grow towards one another to create that desirable solid cedar hedge appearance.
