Research Interests:
Current program research: Plant nutrition of bedding plants including establishing recommendations of common
commercial species, characterizing the visual symptoms of toxicity and deficiencies, determining the molecular
signals of nutrient stress, predisposition of plants to abiotic stress caused by nutrient stress, environmental
interactions of nutrient requirements, the use of silicon as a beneficial nutrient in bedding plant production,
and influence of media types and quality on bedding plant production.
