Irrigating your hedge:

  • For best results, it is recommended during the first four weeks after installation of a cedar hedge, to water it frequently. The base should remain moist during the first month, but not soggy. It is also advisable to water 1 hour every 2 night with a garden soaker hose set to ¾ of your maximum water flow. Watering in the evening and at the base of cedar minimizes the amount of water used, less waste, less evaporation and maximizes the absorption by the roots.
  • The irrigation time may differ depending on the composition of the soil, the depth of the trench, the leveling of the soil, temperature and water pressure. Moreover, it is not advisable to water on rainy days: excess water and humidity would harm the development of your hedge, it will rot the roots and kill your cedars. The best way to estimate the run time is to irrigate ¾ of your maximum pressure for one hour in the evening. The next morning, if your soil is wetted, you must decrease the watering time. If it is dry, you should water longer. If it’s wet your ok.

Fertilizing your cedars:

  • If you are installing, you can promote root development, adding the fertilizer for cedars, on the surface of your plants once you have completed your hedging.
  • In subsequent years, you can add the fertilizer for cedars, three times a year. In mid-April to mid-May and mid-June, sprinkle a tablespoon for each plant above the root zone. This will increase the growth and foliage density, stimulate the root system, increase resistance to disease and cold while giving a dark green color as desired.


  • Do not use other fertilizers as this may damage your fragile hedge.
  • Do not add fertilizer if the work was done by one of our experts because they have already fertilized your trees during the installation process.

Pruning your hedges:

    • It is recommended to trim your hedge by giving it a conical shape, that is to say, wide at the base and slightly narrower at the top. This maximizes the absorption of solar rays over the entire cedar tree and provides a healthy and dense foliage. Furthermore it will help to reduce the weight of snow during the winter.
    • For best results, the first two years following the installation of a cedar hedge, you should prune them twice: a first pruning in late June and a second in mid-September. This will promote faster growth as the cut distributes growth to the remaining leaves. So the more you prune your hedge, the faster it will grow.
