Here is what I thought I knew about spider mites, they like hot dry weather! ha For the past 2 weeks we have had lovely rainy ,humid weather. Suddenly everything in sight is full of spider mites.. green beans, tomatoes, cucumbers, and of course dahlias. Kelthane is supposed to get them, so I'm trying that. Of course I won't spray on my veges, so may as well pull them up and put in the trash. I believe they can live in the soil as I have brought them in the house on ivy when I bring it in in the fall. I don't think they would live on stored tubers.

LOL Jroot no prescriptions here. Good old compost laced with goat poop, Osmocote, recent Mor Bloom and shredded leaf mulch. I think in my photo album I have the caption to Mazama as "Get the ladder..."
I have two other plants of this in various locales. One is 6-7 feet and a late-to-sprout one is only about 4.5 ft.
Here's last years Mazama.


Hope springs eternal! A light frost shouldn't do much at all. It's the heavy sustained freeze that will end your dahlia season. We too have felt the early morning chill, but no where near 0/32. I was in 3 layers yesterday a.m. til the sun came out.
If you heat up during the day, you should have every chance to see your flowers in full bloom.

If it were me and I thought it was going to frost, I would covering my dahlia's at night. I would be checking that weather forecast every night like a mad woman, if the forecast predicted a heavy frost....well I would be running around the yard with sheets in hand. Sometimes you have to do what ya gotta do to save those "babies".
Frost already, you have my greatest sympathy. Good Luck


Hi Pitimpanai,
I read the camera manual on how to select fewer pixels per shot. As it came out of the box, it was taking gigantic photos that took too long to upload and were much to large to store or email.
My nephew sent baby photos of our first grand nephew and after scrolling around endless blanket, I finally found an adult human finger LOL- never did find the baby! It was just an immense file.
So that would be the place to start. Then, I think you use Photobucket also, once you get your photo in an album you select "edit" and go to the resize option. I usually go for 50% of the original size.
See if that works without distorting your photo.

You know what, I got the wrong name, not Edinburg. I have to go back and check the marker now. It is a huge dinnerplate with pink tipped blooms w/the centers a pale yellow.
How can I tell if Fantastico died? I really don't think it is taking a breather since all the foliage and stems have died back too.

It sounds pretty much a goner if the foliage and stems are gone. I had to cut down a stem rotted plant, cut it all the way to the tuber and it is sprouted again and a lofty 4 inches tall LOL- a real towering mammoth. Might be worth a try on Impress. Fant. It can't get much worse off, and perhaps you can save some tubers off the plant for next year.

Poochella, I tried checking on the link for "Show'N'Tell" and I think you nailed it! It is red and yellow and laciniated too. Thank you very much.
I measured the bloom of the first one and it is 8" in diameter. The second one has a diameter of 3 1/4"... does that help? I tried to click on the link of the dahlia forms, it won't work for me either.


ah, that's good to know. maybe i'll leave it here with my mom instead of lugging it to arizona...where do you think it would be happiest?
i found it at a place called Deke's 7 Dees in portland, OR. must not have been very popular this year because they were all on clearance for a buck.

It would probably be happiest in OR. However, you might try it in AZ planted in a light-colored (for cooler roots) container on a lightly shaded patio. The foliage is quite attractive and the plant has a parsley/celery scent. Thanks for the info. on the source - I grow several "wild" species of Dahlia as part of my research in plant systematics.

Willow Wins!!, Willow Wins!!!. It IS a zinnia. And yes, I do know that this is the Dahlia forum. I spied this lovely from the other side of my veg garden and at first look wondered how a dahlia ended up with the zinnias. It would be a pretty Dahlia. And I'm going to save the seeds on this one. Thanks Poochella, thanks Willow for playing.

I would call it coral, coral or pink it's got great form and strong color. Very lovely dahlia!
I planted a couple of Hillcrest varieties but they fell to tuber rot,d.....mmm. Have to buy new ones next year and try again.
Nice camera, Poochella

What a great find for you and congrats on getting them to grow so well already.
I would treat the ones in the pots just like the tubers in the ground because they have been subject to all the nasty little bugs and fungi outdoors. I'd want to dig them, clean them, treat them and store them as usual in a non freezing area. You might be suprised to see that your growing tubers have time to produce some extras you can divide. That's only what I'd do, not what you should do.

You can leave them in pots if you want to. Then in spring take them out & see if they can be divided. This is sometimes a good way to over-winter the ones that you don't think have much chance of having made many tubers or the tubers are small- & it's easy to store them. People who grow from cuttings usually leave the tubers in the pot over the winter- just make sure it's neither too warm nor too cold where you store them. Also lay them on their side so that they drain well & don't rot in storage.




You might want to look at the other string about our sick dahlia. The conclusion was that we have spider mites.
