I bought Dahlia from website , they sent it as bare roots and must planted as soon as possible but i had to keep them 2 weeks more before planting, how can i do that? I put them in refrigerator as the package received with some soil and wet paper I wish you kindly advise me what to do
If the danger of frost has passed in your growing zone, plant outdoors now.
If it is still cold in your garden, plant the bare roots into pots.

I have a flower bed that has become completely overrun by crabgrass and weeds. We are having someone come in and tear out the whole bed and dig the dirt down several inches in an attempt to get a handle on the crab grass and hopefully start fresh. I'm wondering if there is a way to save some of my perennials and bulbs in the process and what the best way of going about that would be? I would have to dig them up, temporarily store them somehow and then re-plant once the bed is ready, likely in 3-4 weeks after being dug up. I have dahlias, coneflower, astillbe, gladiolas, salvia, Liatris and carnations. I am in zone 9b. Thanks for the help!
You can save anything that is a bulb or rhizome very easily with proper storage methods. Anything that is just a root mass will need to be planted in container, immediately, such as the salvia. You can put these in ground when you have a spot ready.

I dug up and stored my dahlia tubers over the winter in a cardboard box with newspaper for add'l protection. They did not rot and are firm. However they have no "eyes". Should I put them in the ground & hope for the best? Also, should I divide them (even tho I don't see any eyes) or leave them just as is?
If they are, relatively, young and you do not see any eyes, then I would recommend planting it as one just to be safe. Then, next year you may divide them up. This article will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/bulbs/dahlia/dahlia-care-grow-dahlia-plant.htm
I used a dahlia tuber to propagate shoots in a box, then cut the new shoot and plant it in a pot. I wonder if the used tuber should be just disposed? Or is it still useful?
It is necessary to have, both roots and shoots on each division. If you are not able to do this, then the tuber is best left alone. This is a nutrient storage organ that is necessary for feeding the plants. If there is none left on the shoot, then it will likely die. Could you send a picture of what you are referring to so that I may help you to divide this correctly? For now, here is an article that will help: https://www.gardeningknowhow.com/ornamental/bulbs/dahlia/dividing-dahlia-tubers.htm
I grow dahlias--always from tubers. this year I bought some dahlia seeds off ebay. They germinated quickly (8-10 days) and look great. But the leaves are thread like--like cosmos leaves. Do some dahlias have this type of leaf? They are supposed to be blue and white--I am sorry I forgot the name. Would be disappointed if these healthy little guys are not dahlias. I can wait and be surprised this summer, but am curious.
Not usually, although some can appear thin due to lack of light. Can you include a photo? This will help me to see what you have.
Hi, I would like to know whether Dinner Plate Dahlias can be grown from Seeds. if it is where are the seeds available? I know dwarf varieties can be grown from seeds not sure about Dinner plates..?
Yes, they can all be grown from seed with some patience. We do not, usually, recommend places to purchase. You can check local, or online nurseries. Most will ship just about anywhere.

I have just emptied a pot of dahlias after 2 -3 yrs of blooms. Most of the pot was corms, I now think it was pot bound. Can I separate them and replant or are they no good?
Many gardeners do not separate the tubers until spring.
Follow the clean knife and dusting with fungicide practice.
Even with the new sprouting, you can break those off and new growth will form from the eyes.
In my research I found that you can plant those long straggly sprouts and tubers can form at the leaf joints.
