šø Hot take: dahlias are not bulbs š¬ Let's talk a little dahlia lingo....
If youāve been calling them bulbs⦠youāre not aloneābut hereās the deal š
Dahlias grow from tubers, and that changes how they grow (and why they sometimes fail).
š Bulbs (tulips, allium, daffodils):
⢠Round + layered (like an onion š§
)
⢠Contain a full baby plant inside
⢠Grow roots from a flat base
⢠Very predictable growers
Dahlia tubers:
⢠Look like little potatoes š„
⢠Solid inside (no layers)
⢠No built-in plant
⢠Only grow if thereās an āeyeā
⢠Grow in clumps from a crown
š” The key mistake:
No eye = no plant š¬
š” Why this matters:
Treating a tuber like a bulb = weak growth, rot, or no blooms
