Invasive Tree Roots.
When a bed is dug in a area with invasive tree roots you remove tree roots. When tree roots are cut the tree
does not repair the damage. The tree responds to the damage in one of two ways.
1) It walls off the damaged site by producing cells to wall off new growth from the damaged site.
2) It produces new roots from the ends of the damaged root.
It is recommended that the same procedures for cutting branches should be applied to roots. This will result in nice clean cuts
and the roots more likely to produce new roots from the end of the cuts. Tree roots do NOT seek anything when they grow. They grow
where conditions are best. So when you dig out a plant bed and fill it with your special soil mix you have created ideal
conditions for tree roots to grow in. The tree roots that you cut around the edge of the bed will now have idea conditions to grow
into. And since they were just cut, the tree will respond to the damage by producing more roots at the end of the cut roots. As
you can see this can lead to a endless cycle of re-digging the plant bed every few years.
So how do you stop the cycle? You have to keep the tree roots from growing into your plant bed. To do this you first need to know what the tree root requires to grow.
