Less water is the ticket to conservation landscaping

13 06 2008

If the first rule of conservation landscaping is to lesson your lawn, the second is to lesson your water use. This can be accomplished in a number of ways, with the most obvious benefit being a smaller water bill. Using less water will also reduce your impact on the earth and encourage another key part of greener gardening: the use of native plants. Plants that are native to your region usually require less water because they are adapted to the climate in which you live, with its unique weather pattern and annual precipitation levels. Let me repeat: the best plants for an environmentally friendly garden are not only native to your country but to your region, as well. Trying to plant a U.S.-native cactus if you live in New Hampshire kind of defeats the purpose.

The first way to reduce your gardening water use is to plant regionally native plants. If you live in the Chesapeake Bay watershed (most of Pennsylvania, Delaware, D.C. and Maryland, with parts of New York, West Virginia, and Virginia as well), the U.S. Fish and Wildlife Service has a detailed photo-book of regional native plants available online. If you live in the Mid-West, check out the EPA’s Great Lakes Native Plants Factsheet. The WildOnes organization is a native plant resource also primarily for the Mid-West, but it has a few Eastern chapters and good information for all. For Westerners, visit the customizable Native Gardening Guide at eNature, which goes for everyone in the U.S., too. Everyone can also benefit from visiting the National Wildlife Federation and Lady Bird Johnson Wildflower Center websites, both of which have spotlights and lists on the native plants of specific U.S. regions.

Another great way to get into native plant gardening is to go directly to nurseries, greenhouses, and nature centers in your area and to ask if they have native plants available. If they do, take notes but don’t buy anything until you check out resources like those above and books at libraries to make sure the person(s) you spoke with know what they are talking about. I have personally experienced several instances where garden center personnel were happy to help but gave false or misleading information about which plants are native. The native gardening movement is growing in the U.S., but knowledge is lagging behind in the commercial horticulture industry. There are, however, some nurseries cropping up that specialize in native plants. Seek these out and support them with your business if you can. Here in Western Maryland, ElkRidge NatureWorks is a beacon of conservation landscaping, covering aspects beyond native plants for their customers.

Some of these aspects also reduce water use, and I want to mention two more: rain barrels and rain gardens. Both capture rain water, the former for your traditional watering use and the latter for the purpose of decreasing stormwater flooding and increasing groundwater infiltration (besides looking good!). More information and how-tos about both can be found in this pdf document from the Center for Watershed Protection. Be careful, again, if you do not live in the Chesapeake Bay watershed, as the native plants mentioned may not be best suited for your region.

Now go and get your hands dirty with a greener garden; if not for the planet, at least for me, since I must garden vicariously.
