PORT ANGELES — Veteran Master Gardener Muriel Nesbitt will help home gardeners diagnose plant problems exhibited by yellowing leaves at noon Thursday.
The free one-hour lecture will be in the commissioners’ meeting room (160) at the Clallam County Courthouse, 223 E. Fourth St.
Chlorosis
Nesbitt will describe what happens when leaf tissue lacks essential green pigment, chlorophyll, and turns yellow, a symptom known as chlorosis.
Possible causes include poor drainage, damaged or compacted roots, high soil pH, nutrient deficiencies in the plant and normal aging.
Nesbitt will discuss how to examine the leaves and the soil to diagnose the problem and suggest measures for correcting it.
Education background
Nesbitt, who earned a doctorate in genetics from the University of Washington, retired from teaching biology at the University of California San Diego.
She directed the Clallam County Master Gardener program from 2009 to 2012.
She is a frequent speaker on sustainable growing and an instructor for the Master Gardener intern training.
‘Green Thumb’
The presentation is part of the “Green Thumb Garden Tips” brown bag series sponsored by the WSU Clallam County Master Gardeners.
