Root Bound Tree Struggles

In October I was asked to visit a property in Jacksonville to determine the cause of the declining live oak that had been planted by a nursery in March, seven months earlier. The tree was experiencing drought stress indicated by a extremely dry rootball and dieback in the crown in spite of a summer of abundant rainfall and regular irrigation.

I performed a root crown excavation with a hand hoe and soon discovered the tree had been planted too deep while ...

Mulch for palms

Posted by:

Generally any mulch consisting of organic material is good. Often organic mulch from palm parts is stringy and not as esthetically pleasing as pine straw, pine bark or wood chips.

Excessive mulching causes strangulation by stem girdling roots.

During the first three months of 2013 Danny and I had been asked to excavate a number of young live oaks (Quercus virginiana) with mulch volcanoes and to fix the problems we found.

We also expected to find an occasional stem girdling root. But we weren’t prepared for the ...

What kind of mulch

Posted by:

Q: What kind of mulch would you recommend to use in beds around and close to our home. In the beginning we used cypress mulch and discontinued it a number of years ago because of the rampant destruction of cypress trees. Then we went to pine bark and encountered an ant problem, i.e. they entered the house. Our pest control people told us that eventually  these ants would attract termites. So we removed all of the pine bark and are ...
