Dr. Paul Fisher

Professor and Extension Specialist / Floriculture

Dr. Fisher manages two university/industry groups to undertake applied research and grower training for greenhouse floriculture production and water conservation. Floriculture is a globally connected network with flow of plant material, inputs, and diseases/pests. We collaborate with other UF researchers, as well as universities and companies around the U.S. and overseas.


    We collaborate in multi-state projects on applied research for the commercial greenhouse industry.

    The Floriculture Research Alliance is a university-industry consortium for applied research on production, propagation, and shipping of floriculture crops. Our focus areas are root zone management (growing media, fertilizer, water), production training, and economics.

    The Clean Water3 research program focuses on water sanitation and quality to help growers capture and reuse irrigation runoff.


    I supervise graduate and undergraduate students in applied research projects.

    These include:

    • Fernanda Trientini (MS, simplified fertilizer supply for small-scale hydroponics)
    • Student research on indoor propagation of transplants, hydroponics, water treatment, and labor efficiency

    Courses Taught

    • I guest lecture in courses such as nutrition for horticulture crops, and hydroponics

    I lead Greenhouse Training Online, a series of English/Spanish online professional development short courses for growers.

    We are developing mobile-accessible grower training and calculators in to help growers to improve production efficiency with information technology.

    Water conservation, sanitation and quality is the focus of Clean WateR3 to minimize runoff and disease-related issues.
