Don’t plant your dahlias yet… grab these 4 things first.
These are the four things I always recommend having ready before your tubers go in the ground:
1. Plant stakes
Add your stake at the time of planting, not later. Dahlia tubers are fragile, and trying to stake after they’ve started growing can damage the tuber or root system. This gives your plants the support they’ll need once they’re full and blooming.
2. Twine or plant ties
As your dahlias grow, gently secure them to the stake every 8–12 inches. This keeps stems from snapping in wind or under the weight of blooms (especially for larger varieties).
3. Bone meal (1 tablespoon per hole)
Bone meal is a great source of phosphorus, which supports strong root development and flower production. Just a tablespoon in each planting hole is enough to give your tubers a healthy start.
4. Plant tags (don’t skip this!)
Trust me… Labeling at planting saves you from guessing later, especially if you’re growing multiple varieties.
