Growing Instructions for Zone 3b

Dahlias are not winter hardy in colder climates and should be planted after the danger of frost has passed. In Zone 3b, tubers must be lifted and stored indoors during winter.

Planting Time
Plant tubers outdoors in late spring once the final frost has passed and soil temperatures reach about 60°F (15–16°C).

Location
Choose a location receiving 6–8 hours of direct sunlight daily with rich, well-drained soil.

Planting Depth

• Dig a hole 4–6 inches deep.
• Place the tuber horizontally with the growing eye facing upward.
• Cover with soil and water lightly.

Spacing
Space plants 18–24 inches apart to allow proper airflow and room for mature growth.

Watering
Water lightly after planting. Once shoots appear, maintain consistent moisture while avoiding waterlogged soil.

Fertilizing
Apply a balanced fertilizer every 3–4 weeks during the growing season to encourage healthy growth and abundant blooms.

Support
Taller plants may benefit from staking to support heavy blooms and prevent stems from bending.

Overwintering in Zone 3b

• After the first frost blackens the foliage, cut stems back to 4–6 inches.
• Carefully dig up the tubers and allow them to dry for several days.
• Store in peat moss, sawdust, or vermiculite in a cool, dry, frost-free location (40–50°F) until spring.

With proper care, Sweet Sanne Dahlias will produce months of glowing peach-toned blooms that bring warmth, elegance, and vibrant beauty to summer gardens.
