Border/Container Dahlias
Watercolor Silks
PERENNIAL GROWN AS ANNUAL
Frost tender
Summer/Fall Bloom
BEST TO START EARLY INDOORS
Sow seeds 2 inches apart in containers of seed starting mix, 4 to 6 weeks before last spring frost. Cover 1/2 inch deep, keep moist and warm and provide a strong light source until ready to plant outdoors. When weather is warm and settled, acclimate seedlings gradually to outdoor conditions. Plant 8 inches apart.
TO START DIRECTLY OUTDOORS
Wait until weather is warm and settled and night temperatures are above 50°F (10°C). Sow groups of 2 to 3 seeds 1/2 inch deep and 8 inches apart in well-worked, fertile soil. Cover lightly and keep soil moist but not soggy while awaiting germination. When well-established, thin carefully, leaving single seedlings 8 inches apart, so plants have room to grow and bloom. Keep well-weeded and evenly watered.
GROWING NOTES
Amend soil with compost or aged manure before planting in full sun. Feed plants monthly. Remove faded flowers to prolong bloom. These dahlias will produce little underground tubers after their first season of bloom; select your favorite blossom colors when in bloom, then multiply those plants by digging up the tubers in late fall to replant the next spring.
TO GROW IN CONTAINERS: Space seedlings 4 to 6 inches apart in containers that are at least 16 inches across and 16 inches tall.
