Pruning clematis: Simplify the ABCs

Clematis alpina ‘Pamela Jackman’ is in the Group or Type 1 or C (oops!) A pruning group. (Sometimes, a proofreader would be handy, too.) Clematis are usually classed as Type A, B or C (aka Group 1, 2 or 3), each with different pruning requirements. I know what the requirements are. Trouble is, I can never […]

Warning: Eastern Filbert Blight

The rather gross-looking cankers of Eastern filbert blight, a fungus that’s not a fun-guy! Run out right now and inspect your corkscrew hazel shrub (Corylus avellana ‘Contorta’) for bumps like these. If you see semi-regular, black cankers along the stems (like I did), your hazel has Eastern filbert blight (Anisogramma anomala). If left to its own […]

Go with the snow. It’s a good thing.

The view is clear when you can see a tree silhouetted in its underwear. Let’s let go of our moaning. Snow in January is a good friend to the Toronto gardener.

Warning: Siberian elm needs a firm hand

While we’re (almost) on the subject of overgrown trees, take a look at this little linear forest (shown in two seasons). This was once a hedge. That is, it was a hedge till someone put away their shears. If you pay attention to the city’s garden archeology, you can spot these runaway hedges all over. […]

Life will intrude (and other excuses)

Drat this vacation. The maniacal rush to get things done before taking a break is screwing up my garden. Next spring, I’ll probably regret not having deadheaded those tarda tulips. Hopefully, all their energies didn’t go into making seed. Just popped out now and sprinkled the seeds over some new ground. Don’t know if this […]
