Small tubers and barely visible eyes
The majority of the tubers I bought this year were very small and most did not have a visible eye. The supplier replaced them, and I planted all of them just to see if the ones that I considered bad were actually good. (The replacements were not much better) Only about 50% of the dahlias are blooming, and some of the ones that I thought did not have an eye are growing, but they are still very small and it is doubtful they will grow enough to produce blooms for this season. So, my question is, just how much of an eye has to be visible for the tuber to be considered good? I used a magnifying glass to look at the tubers when I got them and still could not see an eye. The supplier insisted that they did have eyes, and said that she checked them herself.
I have been growing dahlias for several years, and I have found the biggest "eyes" and best performing dahlias to be from the "Big Box" stores. Please enlighten me for my future dahlia plantings. I LOVE them.
