‘Red Cap’ Dahlias are exquisite in the landscape. Almost perfectly red round balls sit atop lush green foliage. These are very popular in cutting gardens. We provide them in #1 clumps so you get the best product available.
Ball Dahlias are wonderful plants that provide structure and continuous color to any garden with minimal effort. 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.
You can also use in a container. Simply pinch back the shoots after about 3-4 weeks to encourage branching.

Key Planting Tips
Plant in full sun crown 1-2” below the soil. Space ball dahlias about 2’ 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 well in slightly acidic or slightly alkaline soils.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.
