** Answer ** Your pet problem is actually quite common, there are several pet repellent products on the market specifically for your pet problem. Check with your local pet center or garden center. This homemade remedy often works very well also....In a spray bottle combine water and about 3-4 tablespoons dishwashing liquid...or mild liquid soap. Spray the areas that your pet likes to chew, this will leave a bad taste in the dog's mouth and thus refrain him or her from continuing to chew. This is also helpful to your plants and shrubs as this mixture also keeps insects away from your plants. If this method does not work for you...try a little Red Pepper in the chewing areas, this will also help curb the chewing problem without harming your pet. My best suggestion would be to first check with your Vet. before trying even an off the shelf product. Without knowing your planting area...such as drainage and sunlight conditions, it's difficult to recommend types of plants to use. Evergreens such as Junipers and Yews will provide year round green where as Annuals and Perennials will eventually lose their blooms. I've listed some of the popular Perennials that require sunlight and also some that thrive in shady areas below. 1.) Daylilies are one of the hardiest perennials you can grow. They have large, trumpet-shaped blooms that come in many colors and bloom all summer long. This is a great perennial for hot, dry conditions. 2.) Delphinium - And although these don't look like much now, when they bloom early summer, the stately, tall spikes of color, typically in blue, look fabulous. And a nice tip about these, if you deadhead the blooms shortly after they fade, you'll get a second flush of color late summer. 3.) Bleeding heart - Bleeding hearts are an excellent candidate for the shaded garden or even a little bit of sunshine. The flowers line up on a single stem, which gracefully arch over the foliage. The flowers are pink, white, and red, and this plant will grow to a height of one to three feet. 4.) Astilbe - is another perennial made for the shade. The flowers are soft, feathery plumes in colors of white, pinks, and reds. They bloom in mid to late summer. 5.) Monarda, also called "bee balm." The bees love buzzing around the pompom-like flowers, which bloom in the summer through early fall. This is a great plant for sun or part shade, and it's deer-resistant. 6.) Peony - is another classic late-spring-blooming perennial with large masses of petals in shades of pink, white, and red. This is a perfect perennial for the cutting garden. They grow best in full sun, with well drained soil. 7.) Iris - All the flowers basically look alike, and they come in a wide array of color. Some are bearded, some are not. The blooming period is about two weeks in the spring after blooming period, the lance-shaped foliage is excellent filler for the garden all summer long. 8.) Hosta - These are nearly impossible to kill. They come in a wide variety of color, shape, size, and texture. They're excellent for borders and lining pathways. And here's a good tip...if the leaves are blue-green, that means they won't be able to tolerate as much sunshine. If they're yellow-green in color, they can take on more sun. Thanks for The Question !
