So the kids talked you into getting a dog. But you want to keep your lawn attractive. With planning, it is possible to mix pets and plants. Perhaps container gardening is the answer for your flowers.
If a kennel and run is not in your vision, design a cobblestone or decorative pebble area in an interesting shape with some large rocks then train your dog to use only that area. Good drainage is a necessity. Diluting urine will help eliminate yellow spots in the lawn. Wherever you choose to let the dog urinate, hose that area thoroughly and routinely. Raised beds are functional, easy to work in, and will control urination on the gardens.
Select sturdy plants. Coneflowers and Liatris are good possibilities. One poke from a thorny plant will deter your pet. Barberry Bushes have showy purple, gold or variegated foliage and outstanding fall color. Viburnum flowers in spring and exhibits flashy fall color. Flowering trees will provide above ground level color. If you’re absolutely in love with a fragile looking delicate plant, put it in a hanging basket or an elevated planter. If you plan to use evergreen shrubs, note that squirrels, chipmunks, and other small critters may move in around them creating potential for altercations and injury between the wildlife and your pet.
Puppies are inquisitive, and plants like Hollyberry, English Ivy, and Yews are poisonous. If you question a plant’s toxicity, inquire at your local extension office, Master Gardener Hort. Line (319-447-0647), or your veterinarian before purchasing it.
Whether you’re gardening for pets, wildlife or the environment, it’s a good idea to limit the use of chemicals. A pesticide with a taste attractive to insects may also be attractive to your pet. Read the label directions thoroughly: look for pet safe.
The safest mulch for your pet is leaves and cut grasses. Mow, bag, and use generously. Even if Rover investigates what’s under the mulch, he can’t hurt himself by ingesting a chemical. Plus, you’re not feeding the landfill.
Just as kids need discipline, pets can learn respect for plants and lawns, too. Spend some time and effort learning the ropes together. With effort, and a good pooper-scooper, it is possible for flora and fauna to coexist.
