How to Use Limestone in Flower Beds

By Kathryn Hatter ; Updated September 21, 2017

Flowerbeds filled with beautiful blooms are the delight of many gardeners. Enhance the beauty of your flowerbeds by using limestone to edge the borders. Limestone rocks are a natural material that will endure throughout the years to remain an attractive border. Flowerbeds edged with limestone have a finished appearance and the limestone serves to contain mulch materials and prevent them from scattering outside of the growing area.

Measure the perimeter of the flowerbed to reach a rough estimate of how many limestone rocks you will need to edge the flowerbed. Determine the average length of the limestone rocks. Divide the perimeter in inches by the average length of a limestone rock to arrive at the number of limestone rocks you will need. Add several extra rocks to make sure you have enough and purchase that number of limestone rocks.

Measure the height and width of the limestone rocks. Dig a trench around the entire flowerbed that is as deep as the height of the limestone rocks and as wide as the limestone rocks.

Fill in the trench halfway with gravel to provide a solid foundation for the limestone.

Place the first limestone rock into the prepared trench. Pound the limestone in securely with the mallet so that approximately half of the limestone rock is above the soil level. Continue adding additional limestone rocks, placing each rock right next to the rock before it. Pound each limestone rock into the trench securely.

Check the new limestone border after one or two days to see if any rocks settle. If the border is uneven, pound the higher limestone rocks down with the mallet so that the border is level again.
