A string weed trimmer should take care of any greenery, but digging down with a knife every year or so can restore it to "new" if you don't keep up with the trimming as faithfully as you need to. If the stepping stones are set in gravel or crushed granite and weeds are a concern, use organic corn gluten to help control the sprouting of weed seed, or let a ground cover take over. Vinegar and hot sunshine can kill a number of weeds. Agricultural molasses appears to be helpful against sedges.
As for tips, place the stones at a comfortable distance for your own walking comfort. Look at different colors of stone samples by day and night. Finding one that gives good contrast to its surroundings by day and night is a great way to make the steps a nice design feature that can be enjoyed at any time of day.
Yes Tall trees, ground coverings, bright flowers, bird baths, fountains and sculptures are all specifically plotted in one’s garden to create an interesting design and environment that will attract visitors. a Stepping-stones are the fastest, easiest way to build a path. There’s very little digging involved. And although the stone is heavy, a little goes a long way. Since there’s distance between the stones, you don’t have to worry about leveling them with one another. Stepping-stone paths also cost less because you’ll cover more distance with less stone. Stones that are flat and about 18 in. across and 2 in. thick are ideal. Check your local landscape supplier or quarry to see what’s available. If you’re building a short stepping-stone path, you can usually pick the stones you want from the pallet or pile of stones on hand at the supplier. For longer paths, ask for help figuring the quantity and have the stone delivered. If you’re lucky enough to live in an area with naturally occurring outcroppings of stone, you may find stepping-stones free for the hauling. Landscape Gardner Coventry
