| PLease refer to the attached photo of a Sky Pencil planted in March 2012. Notice that one "trunk" is dead, but the others aren't. This is the second of five plants that did this. How can one "trunk" do this without the others doing it, or will they soon follow? |

| did the others die??? i always wonder if some strapping young man.. grabbed it by a branch like that to throw it up on a truck for shipping ... at the wholesaler.. at the retailer ... etc ... on the trunk.. off the truck .. in your trunk.. out of your trunk.. etc ... in other words.. i speculate on physical injury ... as bugs and disease.. usually affect the whole plant.. not individual branches. ... repeatedly over numerous plants... cut it off.. as close to the ground as you can ... it will fill back in .. ken |

| One other did the same thing. I removed it, cut off the dead branch, washed out the container soil, replanted it, mixing in gardening soil with existing bed soil. The other three are alive with no similar problem. |

| After doing some research I'm suspecting that it's phytophthora root rot because "it does discolor the leaves and reduce the vigor of the holly. The leaves may fall off, and the plant could appear to be drought stressed. The fungus actually grows on the roots of plants that are in wet soil conditions. Symptoms start in one limb or branch and then slowly spread. It can take years of exposure before the plant shows serious signs of the disease. Very young plants can die quite quickly from Phythophthora because their root systems are not strong." |

| Yes, partial blighting off of shrubs like this is often root rot. It is seen frequently also on box, rhododendrons and azaleas. Many broad-leaved evergreens need better soil aeration than can be gotten by with when growing various deciduous shrubs. |

| I since spoke to a nurseryman who does NOT recommend Sky Pencil Holly in the DFW area, and he won't sell them at his nursery. |
