Lemon grass is a natural mosquito repellent and grows quite tall. Plant some in deep planters and place on the patio or where you will have people sitting, and you will also have a privacy hedge with the height the grass grows.
Plant lemongrass and rosemary in pots, containers or in flower beds on your balcony or in your garden to have a mosquito free summer. You can use them as herbs in cooking as well. Remember to brush them to release more of their fragrance before your outdoor activity. http://www.roanokemyhomesweethome.com
