More details? Okay.
Eight inches was a good combination for both viability and fitting into pop bottles. When I began noticing multiple ones in the same bottle with leaves yesterday, I looked through the plastic below the bottle labels and saw a lot of white roots. I separated the root clippings at that point. (First photo.)
Thirty-six of the root clippings were 3/16” – 1/4" in diameter and at least six inches long. Those were all M.111. The signs of life among that size range were about equally split between these groupings:
- White roots plus leaves
- White roots plus white stems pushing toward the surface
- White roots plus stem buds formed
- White roots plus exposed portion turned green, like a potato exposed to sunlight
- No sign of life
It seemed to make no difference which end of the root was pointed up. In fact, there was one long clipping that had been inserted in a U shape with both ends exposed and both ends are growing.
I also have a few Dolgo seedling tree root clippings growing. I picked trees that I wanted clones of and then looked for suckers. In some cases, the only suckers they had were dead, but I suspected that the dead suckers might still have viable secondary roots just below the soil surface. I clipped the dead sucker trunks off between the sucker’s own roots and the parent tree’s root and put those in pop bottles as well. (Second photo.)
Of course, I preferred viable suckers if the tree had them. (Third photo.)
I also have some Dolgo seedling trees growing that I dumped wood chips around last year. Some of those sent a multitude of white roots into the chips from their trunks. I shoveled some extra dirt on top of those this spring. I think any of those adventitious roots are fair game once they reach 1/4" diameter, whether they develop suckers or not.
I also have more floor sweeping root clippings in Walmart bag halves that are starting to push up growth now as well. (Fourth and fifth photos.) I need to get those moved into bottles soon, and then maybe cut back on the caffeinated pop.
