In standard greenhouse fertilizers, nitrogen is supplied as ammonium, nitrate, or urea. Each of these three nitrogen sources, when taken up by plant roots, produces different chemical reactions with differing effects on the growing medium pH.

Water alkalinity, fertilizer, and plant species can each play a role in the pH of your growth media.

When untreated, aphids damage ornamental crops and act as vectors for disease. Integrated Pest Management combined with vigilant scouting can help you stay ahead of the problem.

Greenhouse growers have been practicing integrated pest management for decades, but it’s becoming increasingly more important with the […]

This is the first article in a series of case studies designed to help growers
reduce, remediate, and recycle irrigation water as part of a multi-state research
grant (CleanWateR3.org).

While there’s no immediate cause for alarm, experts say the cicada’s egg-laying process can damage woody ornamentals and make them vulnerable to diseases.

The use of plant growth regulators may negatively influence the outcome of biological control programs, according to researchers at North Carolina State University.

The company is now producing Orius insidiosus, Dalotia coriaria, and Dicyphus hesperus at its California facility, reducing the transit time of perishable biocontrols between producer and grower.

Research from the University of Massachusetts highlights the differences approaches to soil media testing, and when to use them.

Improper pH and higher than adequate nutrient levels are among the many reasons for regular soil testing.

While the Environmental Protection Agency conducts preliminary risk assessments of neonicotinoid pesticides and retailers phase them out, the industry focuses on promoting pollinator gardens.

Biocontrols are useful alternatives to traditional pesticides that provide effective pest control in the greenhouse. Here are four ways to get started successfully.
