Developing root flare

(Click on photographs for more information-suggest starting with 1)

The trunk base thickens on many tree where roots emerge from the trunk. This swollen area has been called the root flare or root collar or root crown. This is a key area on any tree. If root flare does not develop appropriately, or if it is injured, trees can become unstable and fall over. Some young trees do not have a visible root flare.
