How to Mark Dahlias

Dahlias are native to Mexico, where they grew in well-drained volcanic soil. In gardens, dahlias need well-drained soil and full sun. The flowers bloom in a range of warm colors -- pink, red, yellow, orange and white -- and in different shapes, including single, double and even pompom varieties. Some dahlia blooms can reach 12 inches across, according to the University of Minnesota Extension. Marking the dahlias you plant will remind you what varieties they are.

     Plant the dahlia tubers in the spring in a sunny location. Dig holes as deep as the tubers and two times as wide. Place the dahlia tuber into the hole so the crown is just above soil level and fill the hole with soil. Pat the soil down firmly.

     Write the name of each dahlia variety you are planting on the plant markers.

     Stick the plant markers into the ground, about 1 to 2 inches deep, next to the dahlias they mark.
