Deer are attracted to well-fertilized plants, such as those grown in gardens. Deer obtain protein, minerals, salt and one-third of their water intake from tender foliage and irrigated plants, according to the University of Georgia. Petunias tend to attract deer.
Petunias (Petunia spp.), a popular garden annual, are occasionally or frequently browsed by deer. Deer are especially attracted to moist plants, such as petunias, in spring and summer.
Petunias grow from 6 to 36 inches tall. Plants can grow as trailing ground cover or as hedges. Petunias produce flowers from May through October in a variety of colors, including pink, purple, red, white and yellow.
Plant petunias in full sun and well-drained, moist soil. Avoid heavy soil, as this can affect blooming. Petunias are susceptible to gray mold, aphid infestation and slug damage. Pinch plants at the end of the season to help plants keep blooming.
