Just a quick question ... I live in Ottawa and have seen several people who have planted Scarlet Curls Willows in their small suburban backyards either near or right beside their pools, yet I have read on-line that their roots are invasive. Are they? Are there a couple of different types of Scarlet Curls?

They are beautiful trees and we'd love to put a couple at the back of our yard, but we don't want to create any problems with our neighbors (they have pools) or with the...

Any thoughts?

We have an old tree we call the snowball tree (big round white flowery balls at this time of the year). Anyway, it has got tons of small worms/bugs that are completley eating the leaves and leaving them lacy. The worms seems to start at the bottom of the tree and eat their way to the top of the tree.

We were wondering if we can buy some sort of chemical(?) or something that we can put on the base of the treee or the leaves to stop and kill the worms. I...

Presumably because the equable conditions that allow for really tall growth also allow for easy all-year leaf retention.

The tallest deciduous tree I can think of is Larix occidentalis, with the tallest currently known being 58.5m tall (Gymnosperm Database:...

I am considering planting Pacific wax myrtle (Myrica californica) in a garden located on southern Vancouver Island. From what I have read to date, this location is slightly beyond the northern limit of the natural range of this species. In addition, this species does not tolerate sub-freezing temperatures very well, and can be damaged or killed, depending on how cold it gets and for how long. Does anyone have experience growing this plant in or around Victoria, or Vancouver? I...
