Now that poinsettias are safely tucked into their prop trays and the threat of Erwinia (Pectobacterium) is almost over, it’s time to think about other Poinsettia issues.
Root rots, nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop. Read on for common pitfalls and how to avoid them.

Do you grow hardy mums and hydrangeas outdoors? If so, this blog post is for you! Flowers Canada Ontario, the Soil Resource Group and OMAFRA have collected data about fertilizer and water management in outdoor greenhouse crops over the last few summers, and have some updated production information for growers to think about over this year’s season.
The goal of the study was to look at ways to improve fertilizer and irrigation efficiency outside of the greenhouse. Continue reading “Tips and Tricks for Outdoor Mum and Hydrangea Production this Summer”
Oedema on the young leaves in this begonia basket.
Oedema, that physiological disorder that appears during periods of low light and high humidity. There’s been quite a bit of it reported in Ontario greenhouses this spring, and unfortunately it’s related to the long rainy (or snowy!) spring we’ve been having. If you’ve noticed salt-like crystals, odd tumour-like growths or water-soaked spots on either side of your plant leaves this disorder might be the culprit.
The disorder affects a wide variety of greenhouse ornamentals. It’s usually noticed in spring crops like sweet potato vine (ipomea), geranium, begonia and/or petunia. Continue reading “Oh dear! It’s Oedema.”
You might have heard that a new cost-share program, GreenON Agriculture was announced last week. This program is designed to help Ontario farm businesses reduce their carbon footprint, and greenhouses are eligible!
This program will be of interest to greenhouse operators who are concerned about rising energy costs, and want to make their operations more energy-efficient.

The summer of 2016 was unusually dry across much of the Niagara Region. Prolonged dry conditions highlighted the need for access to irrigation water and the consequences of inadequate irrigation on crop production.
A number of grower organizations, working together with Niagara Region, were approved for a Growing Forward 2 grant to develop an Irrigation Strategy Action Plan for Niagara. The focus of this work is on farmland used for horticultural production, including grapes, tender fruit, nursery and greenhouse production, below the escarpment. The work is important for the future of your farm and your neighbours. Continue reading “Participate in Developing an Irrigation Strategy for Niagara”
Now that the mums are gone, and the poinsettias are getting ready to colour up, it’s becoming clear that winter is just around the corner. With the colder temperatures outside, comes the ramping up of you heating system. Remember those energy bills from winter’s gone by? Have they got you thinking about doing some energy-efficient upgrades in your greenhouse?
The engineers at OMAFRA have been especially busy this year building GO-CALC – a tool to help estimate your energy use in the greenhouse AND how retrofits can help to make your greenhouse more energy-efficient! The tool shows how those energy-efficient upgrades like energy curtains, new greenhouse coverings and boiler upgrades that you may already be planning for your greenhouse can help you save energy.
