If your yard is a bar, mushrooms are the patrons and the wait staff

The phone call came during my regular CBC radio phone-in show.

The caller had heard Dr. Scholl's foot powder was a fungicide. She knew lawn mushrooms were a type of fungus, so she wondered if she could kill her lawn mushrooms with foot powder – active ingredient Tolfanate, a synthetic thiocarbamate.

"No, definitely not," I exclaimed.

But beware of Calgary's famous hail belt

What's with crazy gardening terms like "deadheading?" It sounds like something done in a dark alley, in private, after midnight.

Patrick Horner, a reader and fairly new gardener, wasn't sure at first, but he figured out from an online search that it meant cutting flowers off after they fade to encourage more flowers. He sent me an email: "If I am deadheading [my dianthus], what do I remove?"

Horner's plant in question is a perennial dianthus – a hardy dwarf relative of the common-cut flower the carnation. If he deadheads it, it may bloom again a bit this season, and will certainly bloom more heavily next year because it won't use up its energy making seeds this year.

When you know it's too good to be true

"Help! This plant is growing behind my office in Calgary and I can't identify it" tweeted Christene.

Gloria had some "wonderful old flowers" suddenly appear in her Canmore yard, so she sent photos by email. Mehran fell in love with a beautiful plant he saw in a Springbank ditch. He texted me a photo. Pretty and mysterious plants were suddenly on all my media.

"Our office building is about two blocks west of the Bow River. There's always a bunch of interesting plants growing out back behind the warehouse loading dock so I'm always trying to identify them, see if there are any plants I can steal to put in my garden. I had never seen anything like this one before and probably spent a good hour trying to figure out what it was," said Christene by follow-up email. But of course anything this exotic and pretty and springing out of nowhere could only be one thing. Christene and Gloria and Mehran all had or wanted to know more about weeds. Pretty, vigorous weeds.

Your chance to get involved in new local book

Calgary real estate professional Lori Olijnyk remembers a particular home home in Calgary's hot inner city: "It had a large 50-foot lot with a dilapidated picket fence that might have been white at one time. Rolls of chicken wire actually had a bird in it. [The] grass was overgrown and the walkway was crumbling."

In other words, it was a mess, and it failed the curb appeal test. The curb appeal was so bad it was hard to get prospective buyers out of the car and into the home.

"A bad first impression is difficult to overcome," said Olijnyk.

Create a natural focal point this fall to view from the inside looking out

I had a single dahlia plant left in my garden. It was battered into the ground by heavy winds and rain. The flowers on the plant, already lying on the ground, had aphids, spiders and slugs living in them. But from a distance, they looked shabby chic beautiful.

Studies show views of nature improve our mood and relax our minds. Improving the view of nature from your window, even if you live on the 10th floor of a high-rise building, might seem impossible this late in the season. But as long as you have a balcony or small patio, improving the view is simple. Just add flowers, dead or alive.

Instead of cutting my dahlias and dumping them, or bringing dahlia blooms with bugs into my home, I clipped the best blooms from my plant and placed them in a large, shallow, water-filled salad bowl. Then, I left the bowl outdoors on my patio table, where I enjoy them from my dining room.

Three garden tasks you don't have to do this fall

Mowing down your perennials the way you mow your lawn is not the best way to spend your time this fall. If you have your shears in hand, gently place them on the shelf in the shed and take a minute to read this fast-breaking gardening news.

1. There is no need to cut back most perennials in the fall:

Gardeners often cut plants back to within an inch of their life while plants are still green, still blooming or still providing interest. If you cut back green plants, you remove stored energy and weaken plants.

Design your landscape to suit your neighbourhood, yourself

For homeowners, their work is never done once they've found their dream home. In fact, it's often just the beginning.

During this time of year, most owners will turn their attention to the yard. My advice: please your neighbours in the front yard and please yourself in the back. Everything else is icing on your landscape cake.
