Our Perennial Planter is a garden tool that allows you to put your heart into your work. Most spades are either too big or too small for one gallon plants. This one is just right. It is very sharp and light weight. Best of all you can use it while on your knees in the garden, and it is great for dividing your perennials. The head measures 4.5 in x 4.5 in and is 20.5 in long.
