Here is the information (recipe) some of
you have asked for from Tom Moore's demonstration at
our June meeting.
2 parts portland cement (do not substitute)
3 parts peat moss, screened
3 parts perlite
Water to make the consistency of cottage
Fibermesh is available from readi-mix concrete suppliers. We
used 1 cup for a roasting pan trough. Use a couple of handfuls for a bigger
trough. Coloring agents are available if you don't like the gray color. Cement
tint mix is available at Lowe's and similar stores.
All measurements are by volume,
dry. We used a large coffee can to measure for roaster size trough. Mix all ingredients well while dry, slowly add water and
mix again. Don't get the mix too wet.
Fill your mold with damp sand so the weight of the mix doesn't
collapse it. Build your walls a minimum of 1 inch thick. One and a half inches
is better. Use 2 inch if any dimension is 24 inches or more. Work form the base
up all around the mold. Don't try to do one side at a time. Leave your work a
little rough for a more natural look, or smooth it out if desired
After you do the top (bottom actually) use a pencil or a
similar size object to make drainage holes. Let dry out of direct sun for about
72 hours. Use a file or shaping tool to even out. Wire brush if
Let cure a month or so before using. These troughs would look
good planted with miniature hostas.
