Dahlias are tender perennials, vigorous and fast growing. Dahlia tubers must be lifted for the winter from the ground in zones 7 and lower.

Planting:

Dahlias require soil that drains freely. Clay soil should be amended. Planting in raised beds can help alleviate moisture concerns. Tuber loss due to moisture rot is the leading cause for plant loss.

Plant 6" deep. Dig hole at least twice the width of your tuber to reduce soil compaction. 

Label and stake your Dahlia at planting. Tubers do not need to be watered unless you are dealing with especially dry conditions. Whatever Mother Nature provides will be enough.

Care:

When Dahlias reach 10-12", the center tip should be pinched. This will create a bushier plan and yield more blooms. Without pinching, the plant will grow one tall, thick central stalk.

Your Dahlias will bloom from mid-summer until frost. Keep spent blooms trimmed and you'll enjoy repeat blooms all season long.
