Do dahlias in containers appreciate lime?
I have run out of sunny garden beds and am planning to plant my remaining dahlia seedlings in several EarthBoxes (rectangular self-watering containers often used for vegetables.) The EarthBoxes come with a package of dolomitic lime which is recommended to be added to the potting mix. Is this necessary with Dahlias in containers? Maybe this is only important for veggies--I just don't know enough ;-)
