Welcome to the Geneva Greenhouses. Here are some of the basics to help you get started.

  • Information about most aspects of greenhouse use can be found in our Standard Operating Procedures. A printed copy is available in the Greenhouse Manager’s office.
  • Our greenhouse operations are governed by a set of Best Management Practices, (BMP’s) that are linked to the right. You will be held to those practices.

Cleaning Up:  You are responsible for cleaning up after yourself.  There is no custodial service. Trash goes in garbage cans, but plant waste and soil belong in the compost piles outside.  Recyclables should be place in appropriately marked containers.

There are pot washing stations in the Barton head-house and the Horticultural Science potting sheds. Materials from isolation houses HS107 and HS108 should be disinfected before they leave that isolation space and autoclaved.

Chemicals:  The rules on the use of chemicals--even innocuous ones--are very strict.

  • Don't use any chemical until you have been trained in the rules and are positive that you understand them.
  • All greenhouse users must attend Worker Protection Standard (WPS) training because there will be chemical use around you.
  • It is safest to assume that there are pesticide residues on greenhouse surfaces, even if you can't see anything.
  • No pesticides may be applied without prior consent and arrangement with the Greenhouse Manager.

Access to the buildings:  Pesticide Applications are applied Tuesday at 4 pm and Friday at 3 pm. You must leave the greenhouse before application times and not return until the next morning even if your material is not sprayed. The doors to the greenhouse are locked after business hours. See your department office for keys and after-hours procedures.

Do not enter other programs' growing spaces. Insects hitch a ride on clothes, so even short visits can spread infestations. Also, others' experiments should not be disturbed.

Plant care:  You are responsible for taking care of your plants. Only two plant-care services are normally provided by greenhouse staff: watering on the weekends and spraying pesticides. In Plant Pathology and Entomology, there are bins of common-use potting mix; in Horticultural Science they are bought by each program. You are expected to have an effective pest control plan and to water and fertilize your own plants.  And you are encouraged to discuss these plans with the Greenhouse Manager so that we can best assist you with meeting your research needs.  Generally you supply or purchase all materials, and each program has their own inventory.

The greenhouse staff manages facilities, such as temperature and lighting control.
The tap water is moderately saline. Fertilizer that is compatible with our water (Excel 15-5-15) is available from the Greenhouse Manager. Our tap water can injure sensitive perennials over the long term. So there is reverse osmosis water in the 4910a and 4910k greenhouse ranges.  Bear in mind that it is very expensive to make R/O water available.  Use it when necessary but use it judiciously.
