🌱 Life Cycle of a Dahlia
Dahlias are tuberous perennials, meaning they grow from underground tubers and return each year (in mild climates).
🌀 Stages of Growth:
1. 🌰 Tuber Dormancy – Resting underground during winter.
2. 🌿 Sprouting – Shoots emerge in spring.
3. 🌸 Blooming – Flowers appear mid-summer to fall.
4. 🧤 Cutback & Storage – In cold climates, tubers are dug up and stored indoors.
With proper care, tubers can last years, producing bigger and better blooms annually!
