Soil is the heart of gardening

A couple of weeks ago, Connie, my neighbour, asked me to take a look at her beloved Japanese lilac. She was worried about its gradual decline. I could see why Connie was concerned. Half the tree had lost all its leaves. Something was obviously wrong, but what could it be?

In the previous blogs, I covered the merits of planting up slopes and the visual delight of terraced slopes. But which method works best for your site? How do we decide? According toUniversity of Nevada Coop Extension, the slope angle decides the method!

In my last blog, I covered slope stabilizing native plants used by Phipps Conservatory and Botanical Gardens in Pittsburgh, Pennsylvania. But there are other ways to tame a slope. Some gardeners in Pittsburgh have tapped in to a 2,000 year old idea: terracing. Of course, the most attractive way to deal with a slope happens to be the most expensive.

Pittsburgh, Pennsylvania surprised me. The city has a whooping 42 percent tree canopy! In comparison, Washington DC has 36% and Portland, Oregon in the wet Pacific Northwest has mere 30% tree cover. Even Canadian cities known for their leafy nature have less tree cover– Toronto 33%, Vancouver, Ottawa, and Montreal all at 20% tree cover. But enough about trees!

Another visual surprise is Pittsburgh’s topography. Hilly. Steep slopes. It’s a great place to see how gardeners tame their slopes. Since there’s too much information to cover in one blog, I’ve divided it this entertaining topic into three blogs.

I believe in supporting botanical gardens. Botanical gardens not only showcase and conserve different plants, but they also play a key role in educating people on the wonders of plants and gardening.

Soil health is a hot topic nowadays, but what does it mean? According to soil scientist, Dr. Dena Marshall, “Soil health is emphasizing the overall diversity of soil biology, which then enhances the resiliency of the soil.”

Early spring has many of us rushing out to buy topsoil (landscape soil/garden soil) either to fill/add to flower beds, build up vegetable patches, or to use on our lawns. But do we really know what we are getting?

It seems fitting to chat about the importance of soil on Earth Day. Over 75 years ago, Henry A. Wallace, United States Secretary of Agriculture, said,

“People in cities may forget the soil for as long as hundred years, but Mother Nature’s memory is long and she will not let them forget indefinitely.”

Soil is essential to life — people and other living beings – as well as Earth itself. I have listed the many ways that soil affects our lives and our planet.
