if you’re looking to jazz up a patio or fill a few pots with beautiful blooms, then growing dahlias in a container or two isn’t just a possibility – it's encouraged! You can grow almost any compact to medium-sized dahlia in a well-placed pot! Here’s how to grow your favourite dahlias in a gorgeous pot like a professional, with help from our gardening experts. How to Plant Dahlias in Pots
If the Dahlia is an appropriate size, it can be planted in containers. Ensure the pot has suitable drainage with holes at the bottom and is large enough for the tubers to grow big and strong! It’s recommended that pots for dahlias are at least 30cm across. Dahlias can be started early in the season, following the instructions below. They will eventually need hardening off (gradually acclimatising them to outdoor temperatures) once the threat of frost has passed. You can also plant them up outside after this point.
1. Fill your pot with any multi-purpose compost until you’ve reached its halfway point. 2. Mix in any organic matter and slow-release plant food.
3. Add your tuber with the stem pointing to the sky and the tuberous roots downward. (If you’re planting potted dahlias, do so at the same depth as they were in their original pot.)
4. Cover with compost, with the stalk just below the soil level. Keep inside, or in a greenhouse while they grow.
5. Water every day, especially during hot weather, or when the soil is dry to the touch.
6. Containers can be moved outside from mid-late May if all threat of frost has passed. Want to learn more about growing and planting dahlias? Our Dahlia growing guide shows you how, with top tips and advice from our gardening experts. What dahlias can you grow in pots?
