This time of the year, some areas can be accumulating growing degree days (GDD) pretty rapidly, while in other areas it is a slower process.

Unheavenly Ambrosia Beetles

I've received a number of reports recently from landscape managers and arborists of thin cylindrical strands of white sawdust appearing to ooze out of small holes in the trunks of recently planted trees.

Name These Flowers
