I would say bare root plants are fine to buy and plant now- I agree they are so versatile, tough,beautiful and good for insects
Don't know about the depth, not heard of that. The bare rooted ones I bought last Autumn I just planted them as I would any other plant.
When raising them from seed, if you nip out the growing tips they then bush out so ultimetley you get more flowers. I would say that this theory would apply to bare rooted ones as well especially if you are putting them in now as they have more time to grow & develop before they flower. I haven't fed my biennial types but I have given the bowles mauve ones a bit of feed during the summer
