Warning: The dreaded Ailanthus altissima

They’re ba-a-ck! Now opening in a garden near you: the first of the yearly horde of seedlings of Tree of Heaven (Ailanthus altissima). Recognize them by the shiny, round primary leaves, followed quickly by pointy secondaries. If you see them, pounce immediately. Tree of Heaven is a prodigiously fast-growing, liberally self-seeding, non-native tree whose fronds […]

Carpenter bees: I’m a bee-leaver

After yesterday’s heartless post on the subject of aphids and leafrollers, it’s incumbent of me [oops, I mean: on me] to say: not all bugs are bad bugs. Not even bugs with bad-boy reputations. Even in this day of catastrophic bee decline, Google carpenter bees, for example, and 99% of the results will be about […]

Hey rose, what’s eating you?

It has been a wet few days. The roses have been slurping up that water and their growing tips and buds are nice and juicy. Mmmmm, say the bugs, the rose buffet is now open! Not for long, bugs. First, meet the leafroller – larva of one of a number of common moths. Leafrollers produce […]

Our baby (dawn redwood) leaves home

In 2007, we wrote about the whip of dawn redwood (Metasequoia glyptostroboides) that Sarah acquired in 2006 at Canada Blooms. Our fledgling tree, nursed along by neighbour M., has now flown the coop, and is planted in a sunny spot just across the street. Dawn redwoods are said variously to be hardy to USDA Zone […]

Open Gardens Toronto – June 2009

Open Gardens Toronto is a fantastic program that lets us take an informal tour of our fellow gardeners’ spaces during the long weekday evenings of summer. (and on Weekends in fall) $25 gets you a pass for a full season, or you can pay $4 for each garden you view. Proceeds go to the Canadian […]

“Red” alert: Lily beetle season

Witness here the final moment of a pretty but destructive Lily Leaf Beetle (Lilioceris lilii), an imported pest now chewing holes in your leaves and buds — and not only of lilies. [Update: What I should have said, two years ago now, was that although it likes lilies best, the lily leaf beetle will nibble […]

Help! Valley-strangling vine!

Spotted during the Toronto Women’s Half Marathon in the Don Valley this morning (with my 15-year-old daughter; her first race) — masses, and masses, and masses, and masses of dog-strangling vine or swallowwort (Vincetoxicum rossicum, syn. Cynanchum spp., from the Greek meaning “to choke a dog”) I’ve written warnings about this pernicious weed before: here […]

Peep into an Open Garden

On a rainy Thursday this week, I popped over to one of the local open gardens, part of Open Gardens Toronto that Sarah wrote about back in April. These are pretty close to “real gardens by real people” all over the city. Check out the link for a garden near you. The one I visited […]

Why gardeners say: Off with their heads!

Make like a squirrel now and lop off your tulip heads – or deadhead them – after they finish blooming and before they put their energy into seed-making. Instead, we want the tulip to fatten the bulb for next year. For tulips, daffs and other spring bulbs, pinch off the seed pod, but leave as […]

Peanut fur: Or why I grow milkweed

This week, Nova Scotia garden blogger Jodi of bloomingwriter wrote about her experience freeing a hummingbird trapped in her barn. It reminded me of a similar thrill of mine. One summer at our place on Ile d’Orléans, in the St. Lawrence River just outside Québec City, the (francophone) kids next door were collecting Monarch caterpillars […]
