Dahlia Tuber Care Instructions

🌱 When to Plant Outdoors:
If your last frost date has passed and your soil temperature is at least 55°F (13°C), you’re good to go! Plant your tubers directly in the ground at this point.

🌡️ Not Quite Ready?
Keep your tubers in their plastic bag with vermiculite in a cool, dark place until outdoor conditions are suitable.

🏡 Starting Indoors:
Want a head start? You can pot up your tuber indoors in moist (not wet) potting mix and place it under grow lights.
🔸 Water only when the soil has dried out.
🔸 Tubers are prone to rot before they sprout and form roots, so be careful not to overwater.

Understanding Your Tuber

Dahlia tubers come in all shapes and sizes—and they’ll all grow into beautiful plants!

  • Some varieties produce long, skinny tubers (like Bloomquist Arise)

  • Others form plump, potato-like tubers (like A-Peeling)

 

What matters most is:

✅ A crown with an eye (this is where growth starts)
✅ A solid neck
✅ Some tuber body
