Incorporating a landscape rockery into your residential or commercial property is a great way to add immense curb appeal while minimizing maintenance. However, there’s a lot of strategy that goes into it, and many property owners make mistakes that detract from the appeal of rockery landscapes. Here are the common mistakes we have observed from clients and why they’re less than optimal for a rock garden.
1. Not Taking Drainage Into Consideration
One of the biggest appeals of a rock garden is that the compiled rocks act as natural drainage. However, this doesn’t mean that you can forget about soil conditions. If the soil is heavily compacted, then water is going to collect and linger no matter how well the rocks are layered. Water accumulation can oversaturate plants and shrubbery, not to mention it can attract unwanted pests like mosquitoes.
Prior to rockery installation, have the soil tested to determine its ability to absorb water. Compact soil may require soil remediation before major renovations can get underway.
2. Using too Many Rock Variants
With respect to rockeries, more isn’t necessarily better. Too much variety can be counterproductive. As a general rule, limit rock selection to no more than two. For most properties, we recommend using rocks local to the Pacific Northwest. The rocks are locally sourced for a positive environmental impact. Plus, it emulates the look of nature that’s within a stone’s throw of your residence. If you want more contrast, then consider one to two rocks of differing sizes, shapes, and dimensions.
3. Using Naked Soil
Naked soil and landscape rockery aren’t a particularly good combination for several reasons. First, the available rocks may not provide adequate shading for the soil, thus exposing the surface to too much heat. The exposure can also be detrimental to beneficial soil organisms. Rock gardens and the soil go best together with adequate mulching. Luckily, there are plenty of mulching materials that complement the surrounding rockery. Aim for gravel and pebbles, and limit the use of compost and wood chippings.
4. Not Addressing Weeds
Weeds can still grow in a landscape rockery garden. Too many weeds can detract from the appearance of the hardscaping features. Mulching will limit weed growth but not stop it entirely. Perform a weed check once a week and pull weeds when they’re in the sprouting stages. Another prevention strategy is to use a weed barrier. Most barrier materials are made from fabrics that match well with the rock-heavy surroundings. They’re also inexpensive and cheap to install.
5. Not Watering Enough
One of the perks of landscape rockery is that it limits maintenance, especially when it comes to watering. However, this doesn’t mean the garden needs zero water. Rock gardens less than one year of age will still require regular watering, especially in the summer. Water every two to three weeks, as well as when the soil appears dry and crusty. The soil should appear moist but not too soggy. Once the garden has had time to establish itself, you can cut back on the irrigation.
