After building a new house in Calgary, NW high in the hills - it is time to get sod for a lawn. I am new to the lawn starting process - and have a fairly large yard with lots of mature trees (14 to 20 feet) on the fringes of the yard - 5 Cherries, 1 Ussurian Pear, 4 Blue Spruces, 2 Maydays, 6 Swedish Aspens, 4 Poplars, 3 Japanese Yews, 2 Maples. Also a large variety of lots of established bushes (about 50 various blooming varieties). Soil is VERY compact with lots of clay and rocks - although I have amended it with various commercial soil products in the areas where the trees and bushes have been planted so they will thrive. The area is protected from west and north winds by a thicket of trees in a ravine - but this also exposes the property to lots of seed borne weeds. I have picked all the rocks out of the whole yard - but the soil has not been amended in those areas where the grass will go. Can anyone help me with tips on (1) the best kind of sod to purchase - hardy and thick, not susceptible to extremes in temperature and varying moisture conditions (2) where I may purchase good quality sod in Calgary (3) the best way to amend the soil for the type of sod suggested (4) where I may purchase good quality screened loam/topsoil in Calgary. Also, about a year ago in one of the Western Canada gardening magazines I read about an odd formula to spray on the lawn to keep the lawn healthy and vigorous - and I can't find where I put the magazine! The forumula had beer (I think!) and some other rather unusual ingredients and was provided by an experienced gardener. (By the way - yes - you read right - the beer is for the lawn and not the gardener!) Has anyone heard of such a thing? Any tips would be appreciated! Thank you.
