Iron-based herbicides (FeHEDTA/Fiesta)

Q What is the best way to control weeds in lawn?

view details »

You can apply corn gluten meal (sold under various trade names both as a fertilizer (10% nitrogen) and as a herbicide) to the lawn to prevent weed germination. The effect builds up over the years. Don't do it prior to overseeding the lawn with grass seeds though as it will dessicate grass seedlings as well. It does not work that well when the lawn never dries out.

However, it will not deal with established weeds which have to be pulled or dealt with through better lawn care practices such as soil tests, aeration, proper mowing, overseeding and fertilizing with "live" fertilizer which provides soil and plants with the proper organisms for their health. Chip Osborne has turned around a lot of municipal properties in the U.S. with cultural methods, especially aeration, which our Regina soils are desperate for.

Q Are there any SK lawn care companies offering the natural lawn care described above?

As of December 2012, no one has notified me that lawn care practices such as soil tests, aeration, proper mowing, overseeding and fertilizing with "live" fertilizer are being offered in SK.

In Regina, you can find companies offering aeration, but my concern with that is whether the equipment has been used on recently pesticided lawn. I am sensitive enough to pesticides that it would likely be a problem for me.

As the City of Regina was discussing reduced pesticide use and a potential bylaw in summer 2012, a lot of lawn care and pesticide industry presentations were made to the City of Regina Environmental Committee and to the Public Works committee. The natural option the Weed Man seems to offer is an iron-based herbicide which has not been accepted in eastern provinces with bylaws such as Ontario and the city of Halfax for health reasons.

Why are iron based herbicides not accepted in Ontario and Halifax?

view details »

Iron- based herbicides are only available as commercial formulations at present.

Ontario and Halifax have not approved iron-based herbicides such as Fiesta under their pesticide bylaw. 

The hazardous materials, according to the Material Safety Data sheet, are sodium nitrate and Nitrilotriacetic acid, or NTA.The MSDS for NTA also warns of potential carcinogenic effects, and that 'the substance may be toxic to kidneys. Repeated or prolonged exposure to the substance can produce target organ damage'.”  (Fiesta/FeHEDTA Letter from the�Canadian Cancer Society)

In addition, over exposure to Iron is toxic. Any potential increase in environmental exposure to Iron through inhalation, skin absorption or ingestion following the application of Iron-based landscape products is of grave concern to the Canadian Hemochromatosis Society (www.toomuchiron.ca ).

Purslane Control in Gardens

view details »

Purslane control (by Paule Hjertaas, 14 February 2020)

Purslane is an annual weed well adapted to dessication. It also has the ability to re-root from every cut piece or if hoed, especially if left on a moist surface.

Are you rototilling? If so, that would make the problem worse, like it would for some perennials like quackgrass, thistles, and the terribly weedy imported Campanula. Loosening soil and hand digging or pulling works best for those in garden setting. You can always get more roots when digging or weeding after a good rain or watering. I always dig weeds before they go to seed, and leave them in piles as mulch, but not purslane, it would only re-root.

My experience is that purslane will germinate well in bare soil or even in cracks on a road or at the edge of a lawn besides the curb where the grass grows poorly. My experience with an ecoweeder trying to get rid of it in cracks or along a curb is that it may be set back but not killed. 

Purslane is edible so you could eat some of it. Chickens also love it, and perhaps so do other livestock. Visiting organic school gardens in Berkeley, California, several had several chickens wandering the garden during the day for pest control and likely also weed control.

Mulching might help but it may bring rodents. If mulching around fruit trees, put a collar near the base to protect them. Some plastic or polyester mulches are also available, although you may not want to go there with the current issues with plastics.

Organic growers grow flowers under fruit trees in orchards to increase pollinators and predators.

So:

1. quit rototilling areas with lots of purslane, especially during the growing season. Hand pull or dig out.

2. try mulching at least some of the area to reduce work.

3. don’t ever let any weed go to seed.

It may take a few years, but I think you will see a reduction of your problem by following these rules.
