Building Stone Borders

Beginning with a pond edge already firm and level (see Pond Building Paradise Style) we use sand to level the rest of the area we plan to flag. Keep in mind that we are in Florida and have no problem with freezing/thawing affecting our stone work. This is as easy as it looks and natural stone purchased by the pallet is relatively inexpensive.
We overlap the pond edge with stone by one to two inches and try to keep the edge thickness fairly consistent. This creates a shadow that hides the concrete pond side. Though we make an effort to keep stone and mortar out of the ponds, some gets in with no apparent detriment to plants. We do usually put a little vinegar in the water near the edge we are working on.
Materials & Tools: Brick hammer, pointed trowel, sand for leveling, bagged mortar mix, a bucket or other mixing container, hose and nozzle, wire brush (in case we don't wash off quickly enough), rubber gloves.
Tips: Several of the keys to attractive stone work are to vary rock sizes and to avoid creating long lines that catch the eye. Don't select or set too many at a time since they don't always go back exactly they have in pre-selection. Don't let the mortar set too long without washing -- wire brushing or a mild muriatic acid wash will help if you do.
