I felt like a fraud last week. I was having dinner with Dr. Linda Chalker-Scott and she was correcting my understanding of wood mulch depth around trees. For years I have been insisting on 4 inches (10 cms) of wood mulch at the base of trees in new landscape installations. She was disputing that…. so If you are using bark mulch tell me how much mulch you use. You may be surprised by Linda’s suggestion.
Yes we all love early blooming alpine flowers and summer-long showy annuals. But sometimes it is the humble shrub that wins praise with its fantastic blooms and ability to welcome the world of pollinators. When I walked outside and saw my ninebark ( Physocarpus opulifolius ‘Tiny Wine’) in bloom I was surprised by the range and number of bees attracted to the flowers.
This spring we are expanding into the “back 40” as my dad used to call the back pasture on the farm. This is an area we recently had to fence because we joined the lot behind us with our main house lot. In doing that we had to clear out the branches and brambles and big stumps that were in the way. And so we were left with a field. A new planting opportunity. This post looks at edible shrubs and will be of special interest to green-thumb gardeners or farmers on a budget.
I was asked to mentor youth as part of the Goodseeds program earlier this winter and I wondered what two students and I would do together for a week once my shed was clean and shears sharpened. It was snowy outdoors so we couldn’t attack my unlimited weeding. I had to get more creative….

INTERVIEW – ALL ABOUT TREES
Donna Balzer : Tell me about this tree disaster you keep seeing in Calgary?
What kind of nutrients do falling leaves really have? Are they just drained out empty shells of their former selves? Answers vary.
Some older studies show commercially collected fallen leaves in urban centers contained nasty elements such as lead and cadmium because the tree leaves were swept up by machine along with portions of lead-contaminated soil.
