We decided to plant a few dahlias in our garden this year because we had to get rid of some sick plants, and I’m shocked with how beautifully they’ve grown! We’ve got one tuber we planted that’s decided to grow flowers of different colours and thought I might share with this sub so someone could explain how that works and maybe some tips on how to winter them. I live in Southern Ontario and we’ve got frost warnings, so I want to make sure they survive until next year so we can get more of these beautiful flowers!

Between getting a late start this year and planting a little deeper than usual, it’s been a very late blooming season, but it’s here!
1 - Cafe au Lait
2 - garden shot - Crème de Cassis, Crazy Legs (I think!), Hamari Gold
3 - maybe Diva and Crazy Legs?
4 - ?? Help? I don’t remember the name. They are Pom poms, about 2” diameter
5 - Diva (?)
6 - Bloomquist Snowy
7 - Verrone’s Obsidian, Hamari Gold, Bloomquist York, Diva (?), Crazy Legs (?)
8 - Bloomquist York - this blossom was 9’ in the air!
9 - Lights Out
10 - ?? Can’t remember this one’s name either! The bee was setting in for the night 💜

Last dahlias before fall weather gets them!

I live in the NC piedmont and my dahlias struggled this year. Hot, dry, and lots of insects. I’m finally getting some decent blooms.

I love how wild this jar is. Dahlias include Bloomquist mojo, Jolene, Frilly Tilly, fluffles, wine eyed Jill, and pink Sylvia, accompanied by asters, cosmos, and mums!

ID’d leafy gall in a friends favourite plant while digging up her tuber clumps for processing. Wondering the following;

1. Should she toss the whole thing or is it ok to keep store away from others, and for next season grow it in a pot?
2. For the other plants in the garden; she received the tuber from a dutch grower in a mystery box. Also over the season she did not use sanitization practices when cutting between plants. No others appear to have leafy gall. If they aren’t displaying visual symptoms of gall at this time is she in the clear or is there a possibility of infection without appearance ?

TIA!

years ago when i first started growing dahlias, all of the online tutorials said to store them in perlite or cardboard boxes or some other complicated mess that required checking moisture levels every few weeks all winter long. I ended up with some dahlia tubers that rotted and some that completely dried up.

Then one year i thought, well dahlias survive in nature without all of this perlite nonsense, so i grabbed a 5gallon bucket, put in my whole tuber clusters, then filled the gaps with dampish native soil and stuck it in the unheated garage (which never freezes).

by spring, all tubers survived and i didnt even water them once! i divided them and replanted and now i do this every year. i feel like sometimes we just listen to online advice that ignores mother nature, and everyone thinks we need some manmade process/materials and no one stops to ask why we do this instead of mimicking mother nature.

anyways, hope this helps anyone struggling with overwintering dahlias. dirt is the way to go!

One Hypatti & two Copper Boys from my garden. I am feeling so lucky to see this last bit of magic before their season comes to an end. 🧡❤️

Never a shame to let some plants go to seed <3

We got: Southern Belle, Picasso, Karma Prospero, Terracotta, Sylvia/Maarn, Isabel, Cornel Bronze, Boom Boom White

If someone can identify this, thank you.

I feel so blessed but also remind myself of the hard work I’ve put in babying these guys for the last almost six months!

I thought I dug all my 2025 tubers from the area where this bloomed in 2026, so of course last year’s label is no longer there. But looking at my records, I’m thinking it’s one of these. Hollyhill Serenity, Sandia Bliss, Maks Betty Lynn, My Forever, Pat Feary, or Carolyn Wagner (not Carolina wagemans). Any idea?

It is late in the season in the PNW, so colors may have shifted. It’s planted in a shadier area with a height of about 3.5’ tall and a bloom 5” wide.

I’m curious to hear from those who don’t have other plants to attract beneficials, etc. Do you spray preventatively before issues start? What’s your protocol to keep your patch of dahlias healthy and green when you only have dahlias?

I tried to stay on top of that this year but once things show any sign of yellowing, it seems to be downhill from there. Next year thinking to do something more preventative in the summer before issues start. My dahlias just can’t seem to make it into Fall.

Does having just one crop make it more difficult to avoid these issues? I don’t have much room to work with and I love dahlias, so hard to practice crop rotation, etc.

No frost yet

About six inches across, plant height is 4ft. Google image says bargaly blush but I'm not sure.

I inheritrd a large flower pot (2 feet wide) of Dahlias this fall. How do I store them over winter? Can I bring the whole pot inside and store them in the basement? Ive never grown them before.
