These stems break crisply off, always straight with plenty of length. It was the third one to bloom for me in early July, and is finally getting a bit tired late in the season... But still popping awesome blooms out with occasional open centers. There are so many good companion varieties to blend with this one in bouquets. Just a delight to work with!


Pulse watering is worth looking into if you are growing in zone 10. Basically, it's less water more frequently, allowing the plants to take sips to stay hydrated through the day. Check out the link describing it... Great info on the site about other topics, too.
Winkie Dahlia is in a very hot part of Australia, and John has figured out how to get dahlias to thrive in extreme heat. Heard him speak at the national show this year, and got to known him a bit. He has a wit about him that'd make your eyes cross... Laughed so hard my sides hurt!

Since no one in that planting zone responded, I'll give you my two cent Monopoly money...
Once you dig the tubers, I would not replant the disturbed roots until spring. Here's my theory on why-- there are lots of fine hair roots that feed the tuber, providing it with an immune system of sorts. If you sever that feeding system in a non-growing time of year, that tuber might rot with the winter rains. I wouldn't want to risk it.
Lots of growers in nice year-round climates dig every fall with the rest of us cold-zoned growers, as it allows them to divide and in turn get more vigorous plants. It also avoids rot when the plant is not actively growing.
Hope this helps, and that someone in your zone adds their thoughts.
Cheers!

Thank you cc!! I read the Georgia dahlia society on the internet and it said to wait til spring to dig up and divide. I sooooo hate to store things over winter so I think I will just wait til April and dig them up then and divide. I'm hoping they will be fine. Your advice was very helpful in steering me in the right direction if I do decide to divide now. Thanks for your help!! Judy

Diane, you're welcome to check out the public albums in my Facebook account... Specifically, Riverside Garden and Dahlia Hill shows overviews of public gardens. They are both really neat locations. I haven't downloaded some other garden overviews to the FB page yet. Perhaps I should make the time to do that.

Hi Diane
I studied kind of "land use policies/politics and landscape architecture". At the Mainau I was with the planning department and was involved with next years annual`s bedding design, counting gazillions of spring bulbs for next year`s order and lots of other plant related planning stuff.
Very interesting time,
well, all the best for your grandson,
bye, Lin


Hi Sheryl, I have a way to store cannas that has been fabulous. when I dig them up I leave the dirt around them put them in a plastic bag slightly moist and put them in the basement. they are ready to go in the spring with large eyes and take off like crazy. I treat them like the dahlias ,I let them get frosted then leave them in the ground for a week. My basement is around 65. they are different from the dahlia tubers because they need to be a little moist. You might try doing this with one to see if it works for you:)
For your small tubers try separating them, wash them ,soak them in a one part bleach and water for a few minutes, then dry really good then wrap them in saran wrap. I only lose about 5% of my tubers this way and I store a 1000. Like with the cannas ,maybe try a couple to see if it helps. Cindy

Thanks for the tip about the Canna! Mine were getting too dry with the dahlias, I guess, because they had a pretty slow start, too. I'll try what you suggested this year.
It's good to hear another grower storing in the 60-65 degree range, as that is what I have to contend with, as well. The long-time growers often say no more then 55, but obviously that's just not feasible for many of us.
With the Saran Wrap method, if there is temp fluxuation, I would not use it. I played with a portion of my tubers last season on the cold porch, and condensation got trapped next to the tubers causing some to rot and some to sprout. The growers I know that wrap with great success all have cold cellars that are a constant temp.

Welcome, Fresaq!
It sounds like either having higher humidity or protecting the seedlings from damp off might help you.
Perhaps Ted can give you further advice or links, as he has much more dahlia seed growing experience then I. I'm sure others on this site will chime in with their experience, given time. This forum is slow, but steady.
Cheers!

No rhyme nor reason to what dahlias sometimes do. I've dug up dahlias in winter only to find a shoot growing when it shouldn't be budding for another 6 months. I had a tuber laying on the ground since February without being planted near my chair and in Sept it started sending up a shoot. It is now about 12-16 inches high but WAAY past the time it would be able to bloom so eventually I'll have to cut off the shoot and replant it next year.
Can't explain why you got MANY shoots except you may be correct that the weather is so nice, it is sending up multiple shoots this late. There is no harm in simply cutting off the shoots and letting it winter as normal. If you let the shoots grow, they will simply grow until they run out of steam and will then simply fall over. And hopefully send up the same number of shoots as now, only next May or June when it is supposed to.

Hurray for the resurrection of shriveled dahlias! They are often tough little buggers. "Pooh" will be back in my garden this year too- so bright and cute.
Jerry D, my thought regarding your question is if you're going to dig a dahlia up, why not just store it in a bag or pot of vermiculite or wood shavings vs soil? Same amount of work, or less, and you'd be using a proven storage media. You can still check moisture levels through the dormant season. Perhaps an experiment of storing some in soil, some in shavings/vermiculite would be interesting to try.

Do moose munch on dahlias? I couldn't imagine an effective deterrent for them, as I understand they habitually like to squash dogs that bark at them.
It makes sense you not wanting to meet a massive wall of muscle and antler in the dark, or a grizzly for that matter, though I would have been tempted, with dahlia craze still blazing...

The moose don't eat the dahlias, but they tromp all over them (and the iris and lilies) on the way to the delicacies they love...almost everything else in the garden.
All my tubers are now dug and stored, so I can move on to cleaning up the yard/garden for winter.

I have been very happy with the sulfur/saran wrap method for the past few years. After dividing, the tubers are tossed in a baggie with garden sulfur and then wrapped individually in saran wrap. Stored in a cool dark place. Last year with over 200 tubers, I lost 3-4 to rot, and none dried up.
It takes a little time, but it works.

I have heard of some tubers surviving the winter in that zone when planted right next to the house with a southern exposure and a mild winter, but that is a rare exception.
Most of us in the colder climates dig our tubers after first frost, and store inside until spring. Others just treat them as annuals, and buy new ones at local club auctions every spring.
There are 'hardy gladiolus,' which never seem to grow for me in zone 5... Perhaps that is what you saw in a catalog and confused for dahlias.

Hi Liza
How do all of your 'offspring' have eyes?
When I dig up tubers and find clumps of anywhere from 6-14 tubers, many are just 'suckers' that hang off the main tuber and have no 'heads or eyes'.
Am I throwing out good tubers? I have sometimes laid them aside or partially planted them in soil to see if an eye develops and they never do. I always thought they were just 'hangers-on'.

Love them all! I have cornbride on order! Awesome!! Will def look for breakout and apricot brandy. Thanks everyone!!
Shilo Jazzman Also bloomed quite creamy in my garden, next to Blizzard which was defintiely whiter.
If you haven't grown Peaches N Cream you really ought to try it...(Note, this is not the same as Peaches and Cream.)
