Where to Plant Dahlias

Dahlias need a sunny location to thrive! More sun equals more blooms. It is recommended that dahlias receive at least 6-8 hours of sunlight per day. Do not plant your dahlias under trees or too close to shrubs as they will not receive enough sunlight or nutrients to thrive. They can be grown with less sun, but please remember that less sun means less blooms and taller plants, reaching for the sun. Of all dahlias to consider growing with less sun, the lower growing and dwarf dahlias will do the best. In hot climates (such as Texas, Arizona, Southern California, many other southern U.S. states, or desert climates) morning sun with some afternoon shade may be best for proper growth. We recommend not growing bi-color varieties in hot climates, as the white tips can burn. Please remember dahlias require deep water 3 times a week or more by a sprinkler or soaker hose for at least 45–60 minutes during the growing season to bloom properly.
