Keep a plastic knife in your garden tool box.
It will open those weighty bags of potting soil or top soil faster than most pricey garden gadgets.
Keep one of these handy.
My frugal gardening suggestion is recycle plastic forks, spoons and knives as plant markers and plastic bag openers.
You will probably use plastic flatware at a picnic this summer and most of it will go into the trash.
They aren’t frugal if you buy them especially for this purpose , but if you happen to use plastic ware this summer, recycling for garden use will keep just one more thing out of the landfill.
