Rabbits will nibble most tender seedlings, so if you want to keep them away from your plants your best bet is to fence your garden. A fence of 1-inch chicken wire should be 2 feet high and buried at least 6 inches deep. Inter planting your flowers with garlic, onions, Mexican marigold or dusty miller deters bunnies. Another option is to spray plants with repellents. Read the label to be sure the repellent is labeled for the plants in your garden. For example, you may not want to spray something foul-tasting on your lettuce!
