Why Landscape with Native Plants?
Landscaping with native plants is the earth friendly way to garden. It is also perfect for today's busy homeowner, who wants a backyard garden sanctuary, but just doesn't have the time or money to maintain a formal, ornamental garden. With native plants you get the best of both worlds: beauty with low cost and low maintenance.
Some of the many pluses of native plants include:
- drought resistance
- attracts butterflies and birds
- low cost
- low maintenance
- helps reduce emissions because there is little lawn to cut
- no need to fertilize
- no need for pesticides or weed killers
and I could go on and on. For more information about gardening with native plants visit some of the articles featured below.
