Using Compost as a Landscape Mulch Material
Uniformly apply compost mulch over the entire treatment area, or in a one metre circle around the plant.
Apply the compost mulch at a 25 - 75 mm layer over the area to be treated (2.5 - 7.5 m3 per 100 m2), or in a one metre circle around a singular plant (20 - 60 litres per tree).
Apply mulch as soon as possible after planting, applying it closely around plant stems but not against them. Water plant(s) in thoroughly prior to mulching, then again after mulching.
It is important to note that the addition of a compost mulch will reduce the required frequency of watering.
In many cases, applying a compost mulch may reduce post planting fertilization, as the compost mulch will supply some soluble nutrients (when a stable compost is applied at recommended rates).
Footnotes:
The Landscape Architect or Designer shall specify the compost mulch application rate depending upon soil conditions and quality, plant tolerances, and manufacturer's recommendations.
For most projects, uniformly apply a 25 - 75 mm layer of compost mulch over the area to be treated, (2.5 - 7.5 m3 per 100 m2). The application rates above are typical for many plant species and sites.
