‘Blue Boy’ Dahlia (Decorative)
The Blue Boy variety is a stunning lilac blue in color. It is very easy to stop and admire the blooms. You will be asking yourself why didn’t you plant more of these since they are breathtaking. We provide them in clumps the majority of the time. Sometimes they will be stand alone with necks and eyes depending on the season’s harvest.
Decorative Dahlias are wonderful plants that provide structure and color to any garden with minimal effort. They do rather well in the middle to back of your beds or even in stand-alone rows. They reward gardeners with an abundance of blooms starting in mid to late summer through frost. Typically they are not bothered by diseases and have attractive foliage until frost.

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.
