Dahlia Growing Tips

Light: Dahlias love the sun, so choose a location with at least six to eight hours of direct sunlight daily.

Soil: Dahlias prefer well-drained, loamy soil. They don’t tolerate water-logged conditions, so if your soil is heavy clay, consider amending it with compost or peat moss to improve drainage.

Planting Time: Dahlias are usually planted in the spring after the risk of frost has passed and the soil has warmed up.

Planting Depth: Dahlia tubers should be planted about 4 to 6 inches (10-15 cm) deep, with the “eye” (the small bump from where the stem will grow) facing upward.

Watering: Dahlias like consistent moisture. Water them deeply a couple of times a week, more often if your area is experiencing a drought. Avoid overhead watering to reduce the risk of fungal diseases.

Fertilizing: Dahlias respond well to low-nitrogen fertilizers, such as a 5-10-10 or 10-20-20. Too much nitrogen can lead to lush, leafy growth and fewer flowers.

Deadheading: Regularly removing the spent flowers (deadheading) will keep your dahlias producing more blooms.

Overwintering: In colder climates (zones 7 and below), you’ll need to dig up and store the tubers indoors over the winter.

Pests and Diseases: Dahlias are generally relatively disease and pest-resistant, but there are a few common issues to watch out such as aphids, botrytis blight, earwigs, powdery mildew, slugs and snails, spider mites, and thrips.
