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
