Gorgeous Gravel Gardens
July 8, 2016
In the last several years, Olbrich has seized the opportunity to improve its sustainability and experiment with a new gardening technique by establishing four gravel gardens. Exhibited at the main entryway to the botanical center, a prominent gravel garden established two years ago displays vibrant blooms of purples, oranges and yellows.
Beauty and low maintenance are two factors that ring true for Olbrich’s gravel gardens. Above the surface these gardens are composed of beautiful drought tolerant plants; below the surface is what makes them low maintenance. A gravel buffer system is established by using four to five inches of quartzite which prevents the roots of weed seedlings from reaching the soil, but allows drought tolerant plants to thrive due to their extensive root systems. While gravel is a major component of this garden style, at first glance you may not see much of it in the gardens at Olbrich. By spacing plants close together to create a tight-knit plant community, the shade from overlapping foliageworks to inhibit weed seeds’ exposure to sunlight, resulting in less seed germination, weeding, and maintenance.
Vibrant blooms and low maintenance seems too good to be true, but once you come to Olbrich and see it for yourself, you’ll be a believer!
