Urban Rock Garden Tips
Creating city rock gardens isn’t all that difficult. Emulating the rocky outcrops and scarce soil of mountain ridges above the tree line, rock gardens are the perfect home for alpine plants. Used to buffer winds, alpine plants grow close to the ground and are great if you don’t have much space for your garden to spread. They make up for what they lack in size with the brightness of their flowers, however. Compact, but brilliantly colored, flowers suited to growing in an urban rock garden include:
Stonecrop sedum Saxifraga Baby’s breath Fried egg plant Bellflowers
Be aware, though: These flowers are all accustomed to mountaintops and, by extension, bright sunlight. If your urban rock garden receives full sun, plant away! If you’re in a very shady space, consider covering your rock garden with moss.
Rock Garden Plants for City Dwellers
A rock garden in the city works best in full sun and should have very good drainage. Try to avoid shady or damp areas. As you’re emulating a mountaintop, your city rock garden design will do best on a slope. It decreases shading, and it ensures better drainage. If no slope exists, build up a small one with your base layer.
First, put out a coarse base layer of gravel or similarly-sized rubble. Cover it with a sheet of heavily-punctured plastic to make a stable base with free drainage. Arrange your rocks on top, preferably with a variety of shapes and sizes. Fill in the spaces between with garden soil and top with a mix of sand, compost, and loam. Now plant your flowers according to their needs.
