Trees grow naturally, why prune them? Training Trees in the Landscape

Pruning trees is a historic practice serving many purposes. These purposes include tree health, longevity, aesthetics, and safety.

However, some people wonder, “Trees are natural and alive, why do we need to prune them? Why don’t we leave them alone and let them do what they naturally do?”. It’s a matter of context. Yes, trees are alive and grow naturally, but the maintained landscapes we live in are far from natural. Maintained landscapes contain living and natural elements like grass, trees, and plants, but they are not in a natural context. In nature, a solitary tree would rarely be seen growing in the midst of a pristine field of Kentucky Blue Grass. In our maintained landscape spaces, natural things are put together in unnatural ways.  This isn’t necessarily bad, it’s what we humans do, and it is important to understand these differences in contexts.

What to do about Emerald Ash Borer (EAB)?

Emerald Ash Borer (EAB) has become a household name and a dreaded pest. Most people have heard of the devastation this pest has wrought on Ash trees in the eastern United States and know that it has an undeniable presence in the Minneapolis and St. Paul areas now. This pest indiscriminately kills Ash (genus Fraxinus) regardless of the tree’s vigor or size. Emerald Ash Borer larvae (youth life stage) create meandering tunnels under the bark which disrupts the flow of nutrients and water between the leaves and roots, eventually this kills the tree. For more details on this pest, life cycle and current location in Minnesota please see Minnesota Department of Agriculture’s EAB information website. Now that this pest is in our backyard, it is time to finalize the strategy to use regarding this issue of EAB.

What’s wrong with my spruce?

In recent years, the beauty of many spruce in the Twin Cities has significantly declined. This is not true for the entire population, but does speak to a large portion of these trees which many of us treasure in our landscape. A healthy spruce is a wonderful visual screen and wind block. It can also host strands of Christmas lights nicely, and when graced with a snowy white garment, there is little more beautiful in our winter wonderland. But lately, hordes of spruce have been discoloring and shedding massive quantities of needles. What is wrong with these plants and can anything be done?
