Using antitranspirants on landscaping plants
Using antitranspirants on landscaping plants (post #18046)
I just read/reread 10 Plants for Year-round Containers by Muffin Evander that is in a link in your October 4 email Planting Ideas for Autumn by the same author. In the article 10 Plants for Year-round Containers, Muffin recommends applying an antidesiccant to plants in container for the winter. in the article http://www.finegardening.com/how-to/qa/antidesiccants.aspx antidesiccants are also recommended.
I suggest your authors and editors read Chapter 10 of The Informed Gardener Blooms Again by Linda Chalker-Scott, University of Washington Press, Seattle, 2010. Linda is and urban horticulturalist and associate professor at Puyallup Research and Extension Center, Washington State University. She is interested in using scientific literature to refute gardening myths. One such myth she addresses in Chapter 10, is The Myth of Antitrtanspirants. The bottom line is that antitranspritants (antidesiccants), when used in a garden or landscaping environment, are more likely to harm rather than help plants. Her bottom line is: "While applied antitranspirants prevent stomal water loss, they also increase heat load, inhibit gas exchange, and decrease photosynthesis."
I realize that some of your advertisers sell these products and your authors may be influenced by this but antidesiccants are not products that belong in the home gardeners toolbox.
For a conclusion I will quote Claudia Larrow in her article When to use antidesiccants found at http://www.finegardening.com/how-to/qa/antidesiccants.aspx on your site.
"It’s best to avoid plant-moisture problems in the first place by siting your plants appropriately, watering the soil as needed, and mulching to conserve soil moisture and to reduce and delay soil freezing so that roots remain active."
I am sure Linda Chalker-Scott would agree with this.




Temporary Display - Why not? (post #18046, reply #1 of 1)
Many organisations use both Foliage & Flowering plants in their displays - for just the period of how long that show/conference/gathering/meeting is running for. The plant(s) is/are for the purpose . That short time-span. And then after that, the plants are put back to 'rest' /recouprerate again - 'till the next time they are required. A bigger storage spacew, the better the time to recouperate. For that short 'show' time - the plants have to look 'perfect'. There will be root damage in getting them there / back. It may be also inconvenient and possibly awkward to water those plants in situ. For those reasons, anti-dessication liquids are a valid tool in the 'armoury' of Horticultural Display Firms.
