For maintaining a healthy lawn that is both eco-friendly and safe for pets, alternatives to traditional pesticides and herbicides include using corn gluten meal as a natural pre-emergent herbicide and fertilizer. Vinegar can be effective as a spot treatment for weeds. Additionally, planting pest-repellent plants like lavender and marigolds can naturally deter pests. Encouraging beneficial insects, such as ladybugs, which consume aphids, can also help control pest populations. These methods reduce the need for chemical treatments, promoting a safer environment for pets and enhancing lawn health.
