What to plant on a black walnut stump....

Submitted by Bombax on Mon, 02/18/2013 - 23:44

I have a black walnut(Juglans nigra) stump. The tree was cut down six years ago. My understanding is that the juglone is no longer active one year after the tree's death. This may or may not be the case. I would have the stump ground out, except that there is a redbud in very close proximity to it. Does anyone know of any perennials, mosses, ferns or anything else that favor black walnut stumps as growing sites?

Amazing feature in iPhoto for mapping photo coordinates

Submitted by Lori S. on Sat, 02/16/2013 - 12:15

I just discovered a very neat feature in iPhoto of which I was completely ignorant. (Gee, I wish Apple would actually provide some instruction documentation with their products!! :rolleyes:) If you use a camera that is equipped with GPS, you can see the geographical coordinates of your photos on a Google map in iPhoto. For example, here's the route of a hike we took into Panorama Meadows in Banff National Park, as shown by the approximate coordinates of various photos I took:

Potential green roof plants

Submitted by ClifflineGardens on Tue, 01/22/2013 - 14:07

I am hoping to draw on the experience of Rock gardeners for potential new plant materials for green roofs. Plants that would work well, would include, those that like it hot, dry, sunny, windy, and exposed, in a gravelly somewhat alkaline shallow soil with around ~20% organic matter, and ~80% mineral. Currently, sedums dominate the market. Other plants in somewhat common use include those of the genera; Allium, Talinum, Opuntia, and Sempervivum.

I'm thinking there's many more out there, that would love a green roof. Any ideas?

Landscape cloth: to use or not to use for a new rock garden

Submitted by Novak on Sat, 01/19/2013 - 10:49

I'm planning a new rock garden, and I'd like advice on whether to lay out landscape cloth at the base. My plan is to create a mound of tufa (with a sandy mix filled in between the stones) above the existing ground, which is loamy soil. Is it worth using landscape cloth to try to discourage worms? I don't think I need landscape cloth to discourage weeds -- the site was a lawn with few weeds.

Thanks for any advice.

What do you see on your garden walks? 2013

We are 11 days late on this topic!
A couple views of some of my garden beds in the last couple of days-- not a whole lot to see! but you see some of the 'ridges' of the rock gardens and berms I've been developing, and looking at them this winter under snow, I've realised that these winter shapes should be taken into account at the design phase, since this is what I see for months at a time!
