Cold Damage to Pittosporum
Dwarf Pittosporum. They're one of the most beautiful, soft textured shrubs we have, but unfortunately they are also cold tender. Now I know it's difficult to say the "C" word when it's 100 degrees in the shade and everybody's burning up, but cold damage is exactly what a lot of people are seeing around town on their dwarf pits.
Now if you look, the leaves start turning kind of an off-colored like that, off-colored green, and then they go to completely brown. If you take a knife and scar the wood a little bit, starting up with the brown going all the way back you'll see the brown touches the green. This is not caused by any insect damage, or disease, or anything else. It's caused by that cold weather that we had back last December.
These are not recommended shrubs for this area. We told you not to plant them. When they died in '83 you replanted them, when they died in '89 you replanted them, and now they're dying in '96. Have you learned anything yet? Dwarf Yaupon Hollis are much better, especially unless you want these big ugly things in your landscape after you prune the dead parts out.
