Root Flares in the wild
I think one of the things I talk about the most lately is the root flare on woody plant material and why it is important. There's a big problem of root flares being buried too deeply in the nursery pots or the field for B&B material. If the root flare is buried below the surface of the soil...the plant will either a) languish in plant purgatory or b) just die. The tissue beneath the bark moves the water and nutrients between the leaves and the roots. If that is buried too deeply, that tissue can rot and die and then the plant dies.
So, one of the questions I get is what does the root flare look like and where should I plant it. This oak tree in my neighborhood is the best example I have ever seen of what we should strive for in planting. The roots on that tree break just under the soil and you can clearly see the flaring of the trunk. That is what we should do when transplanting a woody plant.
