Garden Giant Gunnera

By | Arborist Insights, Company News, Landscaping, Resources, Seasonal, Strata Maintenance, Tips | No Comments

Gunnera manicata is one of the biggest and most spectacular herbaceous plants. It requires a lot of space and is best used as specimen plant in damp bog gardens or beside ponds.

The fat growth buds clustered in the crown are prone to frost damage so cut back the leaves in the fall and pile them over the buds for winter protection.

The Show Is Over….

By | Arborist Insights, Landscaping | No Comments

Pulling spent bulbs is a pleasant seasonal garden task. Yes, sadly, the show is over but we’re making room for annuals! Tulips put on a good show, maybe two and then become erratic. It’s best to change your spring tulip display and get new ones.

Unlike tulips, the bulbs pictured below are all “re-usable”. Daffodils can be naturalized, and the blue Anemones become perennials. Hyacinths are incredibly fragrant. Plant the spent bulbs with their green stalks and cut them back when totally retracted. Another option is drying the bulbs and planting them in the fall.

Enjoy planning your display for next spring.

Versatile Spirea japonica

This is one of my favorite shrubs. It tolerates pollution, produces beautiful tiny flowers in corymbs (flat-topped clusters), and has attractive fall leaf color.

My research showed that Spirea produced a second bloom when cut back after flowering. The picture below shows the results of my field test. The second bloom came, it just wasn’t as profuse as the first.

When the shrub looses its leaves in fall, you can cut back the stems in winter to keep the plant from outgrowing its space.

Is Your Viburnum tinus Full of Holes?

By | Arborist Insights, Landscaping, Resources, Strata Maintenance, Tips | One Comment

Healthy Vuburnum tinus are great plants with fragrant pinkish white flowers. But sometimes your plants get attacked by the Viburnum leaf beetle ( Pyrrhalta viburni) in numbers and soon all you see is tons of holes in your leaves. The larvae attack in spring and adult beetles in late summer.

Now what?

The cheapest solution is to renovate the plants by cutting them back hard at the base and waiting for new growth to emerge. A more expensive but better long-term solution is to remove the plants and plant a more suitable substitute.

Urban Forests Save Lives

By | Arborist Insights | No Comments

“Urban forests save lives” (link) was the heading of an article from The Vancouver Sun (March 24, 2015). And yet, our city trees often live short, brutal lives. They fall victim to storms, bad practices, bad design, and bad or new drivers. So let’s be mindful of the great work our urban trees do and treat them well.
