Pruning and repotting coast live oak

I thought I was in for a simple before and after post about a coast live oak until I began the root work.

After removing a few large roots, I found a pocket of old soil.

Curious about where this would lead, I began picking at the old soil until most of the rootball had come undone.

For those who have repotted old live oaks, you’ll understand when I mention that the compacted soil of black organic material and sand was as tough as concrete. After removing a few more large roots and picking at the soil for two hours, I was ready to put the tree back in a pot.

Instead of returning it to a bonsai pot, I opted to use a large training pot to give the roots lots of space to grow.

I don’t know how the tree will respond to this work, but since it has been relatively weak for the past three years, I thought it’d be worth a try. Will report back when I know more.
