We planted about 35 plants. So far so good. We had one casualty (brushstrokes, so sad, this was a new tuber for us!!!!) with a soaker hose moving and breaking the stalk from the tuber. We are hoping for it to grow a new stalk.... Thanks for the encouragement! Hopefully everything will continue on and remain healthy!

depends on, how pampered they where. If they never got direct sunlight their older leaves might get burnt, but they should produce new ones really fast.
I transferred some Dahlias 2 days ago, about 4-8 inches high, they looked fine yesterday. I had put them on the balcony frequently, when the weather wasnt too cold.
Just mind the slugs, then everything should be fine.

They are pretty dang tough. I always bury mien deeper in the ground then I grew them in their starting pots and they looked sad for about a day and the next they looked great.
Hardening off is another subject. Like said above, a few leaves might get burned, but very unlikely you will loose a plant. Just and FYI, if you snap off new growth by accident, try putting it in the ground too, you may get it to root and have more plants!

Thanks for the info, I wanted to give them some fertilizer before I plant them in the ground in a couple of weeks so that the plants are growing well before I plant them. I always put bone meal in the planting hole but wasn't sure what other fertilizer I should be giving them.

Don't know if this is right or wrong, but I use Jobes tomato stakes, 2 to a plant and put them in after growth is about a ft. about 6 to 8 inches away from the plant.My dahlias grow well. I left them in the ground last winter, and they are all up and growing now.


Hi maxcyk. If memory serves me correctly 10-15-10 was introduced several years ago by w r grace as the perfect all purpose fertilizer. I believe if it were me I would use this at 1/2 strength the first couple of times. Every ten days is usually recommended.

Ah yes! All that Jazz, love all the colors she displays! Mine was so slow getting going last year with our cold gray summer but I did have some nice ones before frost, and will certainly plant it this year. Another nice one is "September Morn". I have to stop and think which is which between those two as they both show blends of nice autumn colors that go well with other flowers. Its nice to see what form "All that Jazz"could live up to if it got in gear here!



I don't plant all of the same color together but I do try to plant complimentary colors together. I have to sit down and figure out where I am going to plant them all, as I have a lot more than I did last year. I did go thur my list and mark off the ones that are 3 1/2 feet or shorter and will put them in another garden where they won't be overshadowed by the taller ones. I will hopefully be planting them in a couple of weeks. Most of mine are already growing in pots and the hot weather last week really helped them grow a lot!

Replant into a bigger pot. It won't miss a beat! You can also pinch back the top now to make it bushier. I've been doing this all morning with my prestarted dahlias in my greenhouse. Take off some of the lower leaves and set it deeper in the bigger pot. It will give the stem more support.

I would prefer that they weren't so far along, but some tubers had begun to mold, so I took them all out to put a stop to that; from there it just kind of took off to seeing which ones had good eyes, and then they sprouted, and then I planted...sometimes I just can't help myself!


Nice thought. You could buy some dwarfs from an Australian grower. They would be ready to grow - if they have enough light and humidity in your home.
