Tips for Success

Choose a sunny spot. Dahlias bloom best in full sun.

To give your dahlias the best possible start, enrich the soil with compost or rotted manure, and an all purpose (5-5-5) granular fertilizer.

Position the tubers in the hole so the stem, where the tubers are joined, is upright.

Sprouts will develop just above where the tubers join the stem. This junction should be planted no more than 1-2" below the soil surface.

Once your dahlias are 8-10" tall, begin fertilizing them with an all-purpose liquid fertilizer every 3 to 4 weeks.

Pinching dahlias when they are about 10" tall will give you a bushier plant with more flowers.

When the first flower buds appear, reduce 2 or 3 of the tallest stems to half their height. This will encourage the plant to produce longer stems.
