Roots of dead dogwood.  10.19.14

 This year I had 3 dead trees.  Two, a Satsuma plum and a Kousa dogwood, were planted summer 2012, did well in 2013, and died mid summer 2014.  The first summer I watered frequently, the second summer I watered rarely.

The 3rd, a Madrone, died without any growth at all.  From what I read, madrones transplant so poorly and die so quickly after planting, I should not have bothered.

I did an autopsy on the plum and dogwood.  It looks like the roots did not grow beyond the original root ball. 

I don't remember if I planted these without cutting away the surrounding roots.  Now I do.  From the book, The Informed Gardener by Linda Chalker-Scott - paraphrased -

The gardener should disturb the root ball, aggressively.  Nursery-grown trees, especially those bought in containers, often have roots that wind around the pot, creating a "root pot" that new roots can't escape.  Roots cross each other and strangle each other.  The roots don't grow into surrounding soil. 

The result is a tree basically growing in a pot, even though there is no pot and it's in the ground. 

The author washes away all soil with a hose, bare-roots the tree, and prunes all winding roots, then replants entirely in native soil, carefully spreading the roots. 

It looks like these trees were victims of my own poor planting technique.   As far as I can see, the roots never extended beyond were the original root ball had been.

The trees are now replaced with home-started trees.  No issues with recovering from nursery abuse, although there's still the forces of nature, and my own learning process.

Gardening is not about what you have, it's about what you create, and grow, and do.

It's not about what you know, it's about what you learn.
