Planting dahlia tubers that have been used to harvest starts. This is my first year taking dahlia cuttings. I have gotten all I need, but a lot of the tubers have new growth, not big enough to take cuttings from but green and healthy. Can I plant the tubers like I normally would and, if so, do I need to remove the new growth? Or can I just plant them with the very top leaves exposed to take advantage of the head start? Thanks for your time! Shannon
Go ahead and plant them, the fact that they have new growth ("sprouts") means they're healthy!

I am considering planting dahlia tubers this coming spring and I wonder if my choice of placement is going to be okay. I have a stone wall that has large mature linden and maple trees on one side and the other side is cleared for the planting garden. The amount of light should not be a problem; however, I am concerned about the mat of fine roots. This root mat is just at the surface and is 5-10 cm thick. Under this, there is just soil. Will this root mat interfere with the growth of the dahlias? I am noticing that certain plants will grow without problem and others just don't do well at all. Many thanks for any advice or recommendations!
Dahlias need full sunshine and warm, loamy, well draining soil.
If the soil is compacted with a net of roots it could be a drainage issue.
Ph should be between 6.5 and 7.0, slightly acidic.
You can add a small handful of Bone Meal in each planting hole and work in well before planting.
The soil could be amended with sand or peat moss or even steer manure.

I dug up my dahlia tubers and the tubers have bumps on them. I have never seen these before on my tubers. Is this a fungus or disease? What should I do?
I am not sure what these bumps are. They may be normal swellings called lenticels that can appear in wet weather. Or, they could be caused by nematodes:

I don't think it is any more serious disease, like crown gall.
What is best way to store my dahlia bulbs for the winter? I am drying them at the moment. Do I split them now or in the spring? Regards, Ray.
Dahlia bulbs should be divided in spring. See this article:

I dug up dahlia bulbs and found big holes in each bulb. Can you tell me what bug is eating the bulbs? Thank you for the info.
Mammals, such as voles, mice, or rabbits, may be eating your dahlias, especially since you've found large holes in the bulbs. Many mammals find dahlia bulbs tasty. Here is an article that might help:

What variety of dahlias are suitable for hanging baskets?
There are thousands of varieties of Dahlias, so making recommendations is very difficult.
Check the mature height and choose the smallest for a hanging basket. Watering and feeding requirements will be greater in a container planting.
