Do dahlias in containers appreciate lime?

emily06June 19, 2009

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 ;-)

Thanks!

Dahlias prefer a slightly acidic soil, so I wouldn't add any lime. I don't know how Earthboxes work, but you might consider adding water-holding polymers (i.e. Soilmoist) to the bottom few inches of soil where the roots will be. Containers need to be watered regularly.

Here is a link that might be useful: about soil and dahlias

Thank you, Poochella!! Your advice has helped me decide not to use dolomitic lime in my dahlia EBs, even though I paid for it LOL!!
