Key Planting Tips
Plant in full sun with tuber 6-7” deep with the crown 1-2” below the soil. Space Decorative dahlias about 3’ apart from any neighbor. Plant when the soil is 60 degrees, well past any frost danger.
Dahlias love soil that is close to neutral and do ok in slightly acidic or slightly alkaline. You can amend soil with 10-10-10 or something similar. Just make sure the first number (nitrogen) is 5 or 10. You can fertilize every 4 weeks to help achieve large blossoms.
Don’t water until the Dahlia sprouts. If your soil is very dry, water the soil first and then let it stand for 30 minutes before planting. Mulch around your plant leaving bare dirt directly above the tuber. You will see sprouts in 7-10 days.
