We use and recommend a fine wood chip mulch. Our mulch was developed for use in Springbank landscapes, which on occasion can be fairly windy. We acquire wood chips from several arborist companies, screen and shred the chips to make a fine ornamental mulch. This will divert materials from the landfill to our site for use in your landscape. Optimum depth should be 75mm to 100mm, this seems to provide the best moisture retention and insulation for the soil.
The main function of mulch is to protect the soil from the wind and sun – to retain soil moisture. It will aid somewhat in weed control, but does not inhibit all of the weeds.
We do not recommend landscape fabric – the soil building process works better if the mulch is in direct contact with the soil. It is always a rule when you do unroll fabric, it will get windy.
Our wood chip mulch is $30 / cubic meter, picked up at the nursery. We can arrange for delivery if you wish. Our wood chip mulch is bulk, eliminating the costly packaging.
