An Ounce of Prevention in Nursery Production

Kyle Daniel, Department of Horticulture and Landscape Architecture, Purdue University

An ounce of prevention is worth a pound of cure.  That old adage is especially true when growing high quality ornamental plants.  Whether utilizing preemergence herbicides as the primary form of weed control or sanitizing equipment, preventing or eliminating a ‘problem’ before it becomes a problem is usually much easier and cheaper than a curative action.  This line of thought should be used throughout a nursery for various aspects of the production cycle.  A few examples of prevention include:

·       only buying disease free liners

·       obtain high quality media that isn’t stored on soil

·       sanitize machinery that comes in contact with media or plants

·       removing old media and pots from production areas

·       discard plant material after pruning

·       many others

These pictures were taken at a nursery that grows containerized plants.  The concrete bins hold the media utilized in production and there is a slope to prevent water from draining into the bins from other parts of the nursery and doesn’t allow water to pool, which aids in the prevention of disease transmission.  This nursery disposes spent media in a location away from the new media in the bins.  The potting shed is located near the bins so that travel time is minimal.
