Additional Gardening Tips for a Pet-Friendly Landscape

Design Ideas

Creating pet-friendly gardens in Iowa means thinking like your pet. Avoid sharp or spiky plants and instead opt for soft textures and shady lounging spots. Use bamboo to form gentle dividers or designate a dog-friendly digging area with mulch or sand to keep them from uprooting your prized perennials.

Maintenance Advice

Mulch with non-toxic options like shredded bark, and skip cocoa mulch, which is harmful to dogs. Water early in the day to keep the soil dry by nightfall and reduce the risk of fungal issues. Choose hardy plants that thrive with minimal intervention, keeping your chores light and your yard healthy.

Interactive Tips

Have you ever tried mixing herbs with flowers in your garden? Combining edible and ornamental plants doesn’t just save space—it creates layers of scent, color, and usefulness. Basil and zinnias make stunning companion plants, while rosemary can anchor flower beds with its woody stems.
